When choosing the artificial turf for your home, you will always want to take into consideration the quality of the product. The heavier the face weight, the more abuse the artificial turf can withstand and the longer it will last. Be careful when choosing which type of artificial turf to install, as some brands look very cheap.
You should know that there are three types of artificial turf:
- Polypropylene
- Polyethylene
- Nylon
Polypropylene artificial turf is the least expensive, which makes it the artificial turf the majority of deal-shopping homeowners will choose. Unfortunately this is a poor purchasing decision, as polypropylene artificial turf has a low melting point, and always wears out easier than the other materials you have to choose. This material is used most often for golf putting green applications.
Polyethylene artificial turf is known for its soft texture, life-like looks in a home landscaping installation and is widely used on soccer fields, football fields, and landscape design. High quality polyethylene artificial turf is just right for your yard with the look and feel of that high cost, high maintenance and water guzzling natural grass lawn. You can’t go wrong with this type of artificial turf. In fact, we guarantee it for 8 years!
Nylon is the strongest artificial turf available. It can withstand high temperatures and weight, and still retain its original shape. This type of artificial turf is also used for putting greens because it is durable and creates a perfect environment for practicing your putt as if you were on the greens. It is not used often for landscaping because of the cost and the stiffness of the pile. It is, however, used as a secondary thatch of yarn to improve overall stability and strength of a higher end artificial turf landscape products. If you are willing to ignore to price tag of installing nylon artificial turf, it won’t feel like soft green grass between your toes. This is best reserved for backyard putting greens and secondary tuft thatches.

Pile Weight
You will often see a term called pile weight, also referred to as tufted face weight or sewn face weight. This measures how much the yarn weighs per square yard, excluding backing or infill, and is measured in ounces per square yard or grams per square meter. If you only want one measure of your carpet, pile weight is the best as it takes into account both the height and density measurements listed below. Generally speaking, the higher the pile weight the better quality and higher durability the turf. At the low end of the spectrum you will see pile weights of 28 oz per square yard or less. At the higher end of the spectrum you will see pile weights of 106 oz per square yard or greater. And there is a quite a large range in between.
Pile Height
The Pile Height is the height of the turf’s blades and is typically 1.50 to 1.75 inches, although much shorter (e.g. 0.31 inch) and taller (e.g. 2.625 inch) varieties exist. Often you will see a measurement for both the grass zone and the thatch zone, with the thatch zone a bit shorter. Generally speaking, unless you have a specific turf application requiring shorter blades (e.g., golf putting greens), be wary of shorter, generally cheaper pile heights of less than 1.50 inches.
Gauge
You may want to also consider the turf’s gauge. Carpet is formed by stitching together the individual blades of grass in rows on a backing at pre-set widths. Gauge is the distance or width between those rows. In the United States this is measured in fractions of an inch with typically gauges of 5/16″, 3/8″, 1/2″ and 3/4″. The gauge you select is partially based on preference and partially based on function. For example, closer gauges mean tighter-packed grass blades and might be used for, e.g., a golf putting green. Wider gauges may be better for athletic fields. For standard artificial lawns, most gauges seem to fall in the 3/8″ to 3/4″ range and, generally speaking, a closer gauge means a heavier artificial lawn which is generally considered higher quality.
Stitch Rate / Stitch Count
A final consideration is the stitch rate or count. This measures the number of blades or tufts per square inch and, similar to gauge, is a measure of the density of the grass blades on the carpet. Stitch rate is typically measured in the number of stitches in a 3 inch by 3 inch piece of turf. Generally speaking, the higher the stitch rate, the heavier and higher quality the grass.

FOR IMMEDIATE RELEASE
December 10, 2009
WASHINGTON – The U.S. Environmental Protection Agency has released results of a limited field monitoring study of artificial-turf playing fields and playgrounds constructed with recycled tire material or tire crumb. The study was intended to gain experience conducting field monitoring of recreational surfaces that contain tire crumb. EPA will use the information to help determine possible next steps to address questions regarding the safety of tire crumb infill in recreational fields.
“The limited data EPA collected during this study, which do not point to a concern, represent an important addition to the information gathered by various government agencies,” said Peter Grevatt, director of EPA’s Office of Children’s Health Protection. “The study will help set the stage for a meeting this spring, where EPA will bring together officials from states and federal agencies to evaluate the existing body of science on this topic and determine what additional steps should be taken to ensure the safety of kids who play on these surfaces.”
Recycled tire material, or “tire crumb,” is used in many applications, including as a component in synthetic turf fields and playground installations. In response to concerns raised by the public, EPA conducted a limited “scoping study” of tire crumb, which consisted of collecting air and wipe samples at three locations near EPA laboratories at Raleigh, N.C., Athens, Ga., and Cincinnati, Ohio. Sampling also was conducted in the Washington, D.C. area.
The limited study, conducted in August through October 2008, found that the concentrations of materials that made up tire crumb were below levels considered harmful. However, given the limited nature of the study (limited number of constituents monitored, sample sites, and samples taken at each site) and the wide diversity of tire crumb material, it is not possible, without additional data, to extend the results beyond the four study sites to reach more comprehensive conclusions.
Bloodsport movie The study confirmed that most of the methods tested were accurate, reproducible and appropriate for measuring concentrations of tire crumb constituents and therefore can be used in future studies.
Study findings
download Snake Eyes * Particulate matter, metals and volatile organic compound concentrations were measured in the air samples and compared with areas away from the turf fields (background levels). The levels found in air samples from the artificial turf were similar to background levels.
* No tire-related fibers were observed in the air samples.
* All air concentrations of particulate matter and lead were well below levels of concern.
* More than 90 percent of the lead in the tire crumb material was tightly bound and unavailable for absorption by users of the turf fields.
* Zinc, which is a known additive in tires, was found in tire crumb samples. However, air and surface wipe monitoring levels of zinc were found to be below levels of concern.
EPA is aware that studies by other agencies were undertaken or completed while this survey was under way. EPA is planning a 2010 meeting with federal and state agencies to review all new study data and determine next steps.

ATLANTA— The California Office of Environmental Health Hazard Assessment (OEHHA), California Environmental Protection Agency, released a report last week dated July 2009 which indicated there is a negligible human health risk from inhaling the air above synthetic turf, says a news release from the Synthetic Turf Council (STC), based here. The release adds that the OEHHA summary also stated “it is unlikely that the new generation of artificial turf is itself a source of MRSA.”
The STC says that OEHHA searched the available literature related to the safety of new generation artificial turf fields, those which contained crumb rubber infill. They analyzed whether these fields emitted levels of chemicals or particulates into the air that are a health risk when inhaled, and also any potential risk factors for MRSA infection. Based on the data from two 2009 New York studies and a 2006 report of indoor fields, they found that “Both reports concluded that these fields did not constitute a serious public health concern, since cancer or non-cancer health effects were unlikely to result from these low-level exposures.”
Other key findings included:
– Analyzing the chemicals detected above the fields in New York, OEHHA noted that “many of these occurred at similar concentrations in the air sampled upwind of the fields” – which suggests that the source of these chemicals was not from the turf fields.
– Cancer risks are negligible, lower than many common human activities. OEHHA created a test scenario to determine the exposure and health risks of an athlete playing on an artificial turf field from age five until age 55 for nearly 100 chemicals. The results showed an exposure to five chemicals with a lifetime cancer risk above one in one million, which is considered a negligible risk. As OEHHA explains “these estimated risks are low compared to many common human activities.” To give context, its Web site states that the cancer risk of breathing California air (in 2000) due to diesel particles was 540 in one million.
– Synthetic turf is not a source of MRSA. OEHHA stated that “It seems unlikely that the new generation of artificial turf is itself a source of MRSA, since MRSA has not been detected in any artificial turf field.” That conclusion is consistent with the findings of the Penn State Jan. 2009 study conducted on the lifespan of staph on grass and synthetic turf, which was sponsored by the STC and the Pennsylvania Turfgrass Council.

Each year over 200,000 children are injured in American playgrounds. 70% of the children injured received their injuries from falls to the surface below the play equipment. Playground safety begins with the proper artificial playground turf surface to protect your children or students from falls from equipment or tripping. Having the proper artificial playground turf surface is critical to ensuring that a simple fall from a slide or swing will not turn into a trip to the emergency room. Our artificial playground turfs are certified to meet critical fall heights requirements and are designed to create a safe and realistic surface that will keep your little ones playing safe and happily for years to come.
What is the “Playground Critical Fall Height for playground surfacing?
The playground critical fall height of a playground surface is based on the height of the highest piece of equipment that a child can stand on. This height will determine the thickness or impact attenuation a playground surface must have as described in ASTM F1292.
ASTM F1292 testing will provide a “critical height” rating of the playground surface. This height can be viewed as an approximation of the playground fall height which is below the level that would be expected to cause a life threatening head injury.
When looking for artificial playground turf surfacing it is very important to have the manufacturer or installer provide the playground critical fall height rating of their materials. ArtificialTurfSupply.com’s playground artificial turf products (ProPLAY PLUS series How to Sleep rip ) have a critical fall height rating of 7 feet. Make sure you are buying the right playground surface for your playground. You can’t put a price on the safety of the children playing on your playground.
How is the “Playground Critical Fall Height determined?
The most common way that artificial playground turfs are tested is a method used for evaluating the shock absorbing properties of a playground surfacing material. This method is dropping an instrumented metal head-form onto a sample of the playground surfacing material and to record the acceleration – time pulse during acceleration. Simply put, how fast and hard the metal head-form hit surface from varying heights.
Note: For both field and laboratory test methods please refer to ASTM F1292.
Pinocchio hd How is the height of the playground equipment determined?
Conan the Destroyer movie download The Shoes of the Fisherman film The Playground Critical fall height of equipment is determined by the distance between the highest designated play area of the equipment and the play surface underneath. This is measured form the point at which the feet can stand and not the overall top of the playground equipment. Many pieces of equipment have tops of coverings so the measurement is not taken form that point but where the child would be standing at the highest point during normal play.
The Mouse That Roared movie For example if you had a pyramid, climbing up that pyramid you would not be measuring the fall height from the very tip of the pyramid since you can’t stand on the tip. You would measure form the point at which the feet can stand.
Why is the Playground Critical fall height important?
There are a lot of companies out there that would tell you don’t have to worry about the fall height of your playground surfacing. We have seen many playgrounds especially in private pre schools where they will use an indoor outdoor carpet with a pad underneath it. May of the schools can have a long history of injury free play but all it takes is one bad fall by a child that can result in life threatening injuries. Once a child is severely injured or even worse, suffers a fatal injury, the money saved by installing an inferior playground surface becomes very unimportant, not to mention the legal liability this situation can create.

When a player falls, the impact is absorbed either by the playing surface or the player’s body. The “harder” the surface, the greater the amount of the impact absorbed by the player’s body; and, not surprisingly, the greater Concussions are a common injury the likelihood the fall will result in injury. This is especially true with respect to concussions – traumatic injuries to the brain – which can occur when the player’s head hits the playing surface. Concussions are an insidious form of injury. The effects of individual concussions are most often fairly mild. In the case of multiple concussions, however, the effects can be cumulative and the consequences can be long lasting - even permanent. Additionally, if a player has already experienced one concussion, they are more likely to experience another; and subsequent concussions carry a much higher risk of serious injury – up to, and including, death. If for no other reason than to lessen players’ exposure to this type of injury, it is important to monitor the impact-related characteristics of sports surfaces.
Impact testing (commonly referred to as Gmax testing) is used to measure the shock-absorbing properties of sports surfaces – including synthetic (artificial) turf and natural turf athletic fields. Gmax values express a ratio: the ratio of the maximum acceleration (deceleration) experienced during an impact, to the normal rate of acceleration due to gravity. The higher the Gmax value, the lower the shock-absorbing properties of the surface. Gmax measurements are a fundamental tool of athletic field safety testing. They are also useful in assessing the playability of a field.
Gmax testing involves measuring the shock absorbing properties of a playing surface in situ, and comparing the results against a standard. The most commonly used standard is the one established by ASTM
International (ASTM). For synthetic surfaces, ASTM specifies that the reported Gmax value for all test points on a field should be less than 200 Gmax (as measured in accordance with ASTM procedures F355-A and F1936). If the standard isn’t met, the field is considered unsafe and remediation is required.
Secretary dvd While the maximum threshold value of 200 Gmax is the de facto standard for evaluating the safety of an artificial field, many architects set different standards for the fields they design. These alternate standards typically involve a range of acceptable Gmax values. The range sets an upper limit that addresses safety, and a lower limit that focuses on playability. The operative assumption is that fields that are too “hard” are dangerous, while fields that are too “soft” contribute to excessive fatigue and poor player performance. The range of acceptable values will vary in accordance with the materials and methods used to build a field, and also as a matter of the architect’s personal preferences.

Where the Wild Things Are film More than a year has passed since the U.S. Consumer Product Safety Commission concluded that athletes are not at risk of suffering health consequences related to lead exposure from pigments used to color synthetic turf fibers. That statement thus assuaged fears of municipalities and school districts, many of which had declared their synthetic fields off-limits, and effectively nipped in the bud a nationwide panic. Nevertheless, turf manufacturers immediately and voluntarily began reducing lead levels in their products to comply with the same strict standards that the Consumer Product Safety Improvement Act of 2008 requires of the toy industry.
An Innocent Man movie download In fact, the turf industry has been fighting a two-front battle for more than a year. Still unresolved in the eyes of some observers, the current health issue involves recycled crumb rubber, the most commonly used synthetic turf infill. As many as 25 million used tires are recycled into infill each year, according to the Atlanta-based Synthetic Turf Council, a consortium of industry manufacturers, and the material also serves as a popular playground safety surface. “Rubber tires are made with chemicals that are known carcinogens,” Susan Buchanan, an assistant professor of public health at the University of Illinois at Chicago and associate director of the university’s Great Lakes Center for Children’s Environmental Health, told the Associated Press in May. “The question remains, does that raise the risk for cancer for children? We don’t know.”
A study jointly released less than two weeks later by the New York State Department of Environmental Conservation and the New York State Department of Health offers some answers. The agencies collected laboratory and field data from a small sampling of fields to “assess the potential impact to both surface and ground waters due to leaching of chemicals, assess potential public health impact from air release of chemicals and evaluate surface temperature and indicators of heat stress.” The findings conclude that the “crumb rubber material used in synthetic turf fields poses no significant environmental threat to air or water quality and poses no significant health concerns.”
Past studies performed by government agencies in other states have been less conclusive but similarly favorable. “Insufficient information was found to perform a complete formal exposure assessment/risk characterization on crumb rubber for the stated outdoor use at this time,” declared a 2007 report prepared by the New Jersey Department of Environmental Protection’s Division of Science, Research and Technology. It added that, outside of potential reactions from individuals with allergies to latex, rubber and related products, “there was no obvious toxicological concern raised that crumb rubber in its intended outdoor use on playgrounds and playing fields would cause adverse health effects in the normal population.” Another study that year, by the Connecticut Department of Public Health’s Environmental & Occupational Health Assessment Program, yielded comparable results.
Still, the Environmental Protection Agency, which does not classify scrap tires as a hazardous waste, recommended in a January 2008 internal memo that the organization take a neutral stance on the issue. The EPA, however, is now conducting a small study of its own in order to determine if the issue warrants greater analysis. Earlier this year, agency officials collected air samples from five synthetic turf sites with rubber infill to determine whether the crumb material is emitting toxins (blade samples also were being evaluated). Results of that small study were expected by summer’s end, according to EPA spokesperson Dale Kemery, but “they are not going to provide the definitive answer,” he says.
Synthetic Turf Council president Rick Doyle insists that enough data already exists to provide a definitive answer. “The science is clear,” he says, adding that he would welcome a statement to that effect from the EPA. “The questions have been asked and answered many times,” Doyle says. “We’re a little concerned about ideology subverting evidence.”
Regardless of what the data shows, industry veterans are aware that the attention paid to synthetic turf’s environmental impact may make facility operators leery of crumb rubber infill, also known as styrene butadiene rubber (SBR). As a result, several manufacturers have created a variety of environmentally friendly alternatives (and there are, of course, some turf systems that require no infill).
Among the more traditional alternative-infill offerings are ethylene propylene diene monomer (EPDM), a vulcanized synthetic rubber, and recyclable (but not recycled) non-vulcanized thermoplastic elastomer (TPE). Both are odor-free, high-density materials available in multiple colors. EPDM granules also often contain chalk, processing oils, UV stabilizers, antioxidants, pigments and vulcanization materials. TPE, on the other hand, boasts the fabrication characteristics of conventional thermoplastic (such as polypropylene and polyethylene) and the performance properties of thermoset rubber.
Other toxin-free alternative infills include:
Dracula video * Elastomer-coated sand, which reduces field temperatures and limits/inhibits infill kick-out.
* A combination of coconut fiber and cork that is organic and recyclable, and also absorbs humidity.
* A blend of organic and inorganic compounds covered with an antimicrobial agent that protects against bacteria, fungi and mold.
While it’s difficult to pinpoint the market share for each of these alternatives, their manufacturers claim that they provide playing characteristics comparable to or better than traditional SBR. “I can’t project what the market impact will be, but it’s an option,” Doyle says of these types of materials. “And that’s important for those who want to consider something other than crumb rubber, for whatever reason.”

Study Finds Crumb Rubber Turf Poses No Significant Threat To Air/water Quality
Tests Show No Health Concerns at Synthetic Turf Fields
ALBANY, NY (05/29/2009; 1219)(readMedia)– A new study released today by the New York State Department of Environmental Conservation (DEC) and the Department of Health (DOH) concludes that crumb rubber material used in synthetic turf fields poses no significant environmental threat to air or water quality and poses no significant health concerns.
The study, available on DEC’s web site (details below), assessed the potential release of chemicals in crumb rubber to the environment. Crumb rubber, produced by grinding scrap tires, is a common “infill” material for synthetic turf fields. It provides cushioning and helps to hold the carpet down and keep synthetic grass fibers upright. The study only addressed the crumb rubber infill and did not address pigments used in synthetic turf fibers that in older applications are known to contain lead.The study found:
Leprechaun 4: In Space Angelas Ashes hd
– No significant threat from chemicals leaching into surface water and groundwater. While some chemicals can be released from crumb rubber over time, they are in small concentrations and are reduced by absorption, degradation and dilution — resulting in no significant impact on groundwater or surface water.
— Lead concentrations in crumb rubber are well below federal hazard standards for lead in soil and do not represent a significant source of lead exposure.
– Levels of chemicals in the air at synthetic turf fields do not raise a significant health concern.
– Synthetic turf fields can have significantly higher surface temperatures compared to nearby grass and sand fields, although factors of heat stress did not differ noticeably among surfaces. Still, the study notes that prolonged contact with hotter surfaces has the potential to create discomfort, cause thermal injury and contribute to heat-related illness.
Best of the Best 3: No Turning Back video
To carry out the study, state scientists conducted lab tests on crumb rubber samples obtained from manufacturers and conducted tests at synthetic fields. They tested for leaching, exposure to acid rain and acid digestion, exposed samples to a range of temperatures to observe impacts, assessed chemical particle sizes for their potential to move through soil and air, collected soil samples at wells down-gradient from existing synthetic turf fields and measured air samples upwind and downwind of such fields. DEC will continue groundwater and surface water testing related to this issue.
download Village of the Damned movie
Led by DEC’s Division of Solid and Hazardous Materials and the Division of Air Resources, the state pursued a comprehensive evaluation of potential chemical releases from crumb rubber. It involved an interdisciplinary approach, drawing upon expertise in DEC’s and DOH’s other programs including water resources, remediation, laboratory, chemistry and fish and wildlife.
The study is available on DEC’s “Waste Tire” Web page, http://www.dec.ny.gov/chemical/8792.html (at the bottom of the page).

Filed under: guilford high school, toxins, synthetic turf
By Pam Johnson, Courier Senior Staff Writer:
Anyone with concerns of environmental toxins leaching from Guilford High School’s synthetic turf may now have their fears allayed, as independent testing has validated the environmental safety of Kavanaugh Field.
The Cheshire firm of Milone & MacBroom ran extensive tests for water and air quality and measured for excessive heat at the field, said Guilford Parks and Recreation Director Rick Maynard. The firm asked to do the tests at a time when some concerns were being fielded about toxins leaching from synthetic materials, particularly from impact-absorbing granules known “crumb rubber.”
“If there were concerns, we’d all want to know about it. We’re thankful for [the study’s] result—it’s certainly not a bad thing for people to know for sure, and this is a good thing,” said Maynard.
Maynard pointed out the town’s field, manufactured by FieldTurf Tarkett Co., was selected due to the company’s excellent reputation and environmental safety record.
“We felt they were the best in the market and that’s why we went with them,” said Maynard.
Guilford was contacted last year by Milone & MacBroom, a civil engineering, landscape architecture, and environmental science surveying firm. The firm sought to answer questions asked by various town commissions, said its environmental scientist, Scott Bristol.
“We design parks and playing fields. The bulk of our playing field experience is with natural turf. Since we also do design synthetic turf fields for schools and towns, we’re often in front of planning and zoning and inland wetlands agencies for approval. They start asking questions, as they should, and when it got around to some of the fields—in particular, synthetic turf fields—they were asking questions we didn’t have answers to. We set out to collect some information.”
Master and Commander: The Far Side of the World dvd Guilford and two other Connecticut towns (not in this area) were asked to participate, said Bristol. The Guilford testing ran through August 2008. Milone & MacBroom based its results against laboratory tests from a 2007 Connecticut Agricultural Experiment Station study.
“In general the state’s study is very similar to the work that we did,” said Bristol, noting the exception that Milone & MacBroom conducted testing in the field.
Among its tests, the state lab determined a toxin, benzothiazole, could be released from rubber when heated.
“If that happens in a lab, then it happens in the field, assuming their data was accurate,” said Bristol.
But concentrations found under lab conditions proved far different from a “real world situation,” he said.
“They took a few grains of rubber, put it in a vial and measured what was concentrated in the air above. When a container is sealed and heated, it represents the worst-case scenario,” Bristol said, adding “No one plays in a test tube.”
The lab test concluded there would be a “relatively high” concentration of benzothiazole in air above the fields on hot days. But tests done by Milone & MacBroom on hot July and August days proved otherwise.
“On the field, with wind, temperature, moisture, and other variables; we found differently. The [state lab] found benzothiazole at a relatively high concentration, [approximately] 225 micrograms per cubic meter. In Guilford, there were extremely low levels in air taken above the field—approximately .39 micrograms per cubic meter,” said Bristol.
Bristol noted that the Department of Public Health hasn’t established a formal threshold for benzothiazole exposure, though informally it’s developed one, “many, many times higher” than the Guilford results.
Another toxin released into the air by heated rubber, tertoctyl phenol, was “not detected at all,” at the field, said Bristol. He said the findings were consistent with the state lab test, which found tertoctyl concentrations “something like 100 times less than benzothiazole. We found little to none—in fact, none.”
The firm tested an air column rising to four feet above the playing surfaces and also air upwind and downwind.
“We set up five sample locations, four around the field plus one directly on the field, in the event a breeze was carrying anything off the field or if a breeze was carrying anything onto the field,” said Bristol.
The firm also came out in the rain to test water run-off from the field, spreading tests out at fields “over the course of about one year,” said Bristol.
In Guilford, “we collected water from drainage pipes leading from the field prior to mixing with any other source of water,” said Bristol. “We knew what the pipes were constructed of [PVC], to eliminate any metal contamination from pipes. Basically, we collected water and compared to standards set by the Department of Environmental Protection (DEP).”
Elvira, Mistress of the Dark move
The study tested for zinc and lead levels and how the run-off water affected a test species. According to Milone & MacBroom’s report, “results of the study indicate that the actual storm water drainage from the fields allows for the complete survival of the test species known as Daphnia pulex. An analysis of the concentration of metals in actual drainage water indicates metals do not leach in amounts that would be considered a risk to aquatic life, as compared to existing water quality standards.”
The report also noted laboratory-based tests for metal, using EPA methods, indicated “metals will leach from crumb rubber; but in concentrations that are within ranges that could be expected to leach from native soil.”
When asked why tests didn’t include risks from accidental ingestion of crumb rubber (sprays of which sometimes kick up during play), Bristol said an incredibly large amount of crumb rubber would need to be ingested to create a health issue.
“I don’t think anyone considers it an issue. The thresholds for what’s called direct exposure that are set up by the state assume daily exposure for 30 years.”
The final test conducted in Guilford gauged the level of heat the field could reach.
“We’d heard from a variety of sources the rubber on these fields reaches as much as 160 degrees,” said Bristol, adding the field certainly heated up, but, “we were surprised to find how cool the rubber could stay. The reason is that, when you look at the field, you don’t see black rubber, you see green. The rubber’s down about an inch or so. There’s is a lot of shading effect that happens.”
Like aluminum foil instantly cooling after it’s pulled from a hot oven, the synthetic grass blades dissipate heat quickly, said Bristol, because of a lack of mass to store heat.
Just as with other outdoor synthetic playing surfaces (such as tennis or basketball courts), the synthetic field will heat up. The highest testing temperature found crumb rubber reaching 112 degrees on a 100-degree day at another Connecticut field, Bristol noted, adding, “any chemical reaction tends to increase with increasing heat.”
Maynard said the field is not used on exceedingly hot days.
“It definitely does get hot. It also answered the question about can kids get burned—the grass doesn’t hold the heat very long, so they won’t get burned on it. But the bottom line is we don’t schedule things there in July at noon,” said Maynard.
Maynard hopes this testing will help put to rest any questions about the safety of Guilford’s synthetic field. Maynard said there soon may be more test results for residents. This week, representatives from the Connecticut DEP are visiting Kavanaugh Field to determine if it will be included in round of DEP tests.
“The DEP now [has] funding to study synthetic fields, and they want to do 10 fields all over the state. They requested permission to do ours. They’re coming to look at and if they want to test it again, we’d welcome it,” said Maynard.
As for the safety of synthetic fields such as Guilford’s, Bristol said, “we’re not necessarily recommending everyone install a synthetic turf field…we’re telling people that if you’re worried about a synthetic turf field, don’t let the environmental issues influence your decision-making process, because there doesn’t appear to be any issues. Make your decision on your usage and what you want for your teams.”

CPSC Staff Finds Synthetic Turf Fields OK to Install, OK to Play On
WASHINGTON, D.C. – The U.S. Consumer Product Safety Commission (CPSC) staff today released its evaluation (pdf) of various synthetic athletic fields. The evaluation concludes that young children are not at risk from exposure to lead in these fields.
CPSC staff evaluation showed that newer fields had no lead or generally had the lowest lead levels. Although small amounts of lead were detected on the surface of some older fields, none of these tested fields released amounts of lead that would be harmful to children.
An Officer and a Gentleman dvd
Lead is present in the pigments of some synthetic turf products to give the turf its various colors. Staff recognizes that some conditions such as age, weathering, exposure to sunlight, and wear and tear might change the amount of lead that could be released from the turf. As turf is used during athletics or play and exposed over time to sunlight, heat and other weather conditions, the surface of the turf may start to become worn and small particles of the lead-containing synthetic grass fibers might be released. The staff considered in the evaluation that particles on a child’s hand transferred to his/her mouth would be the most likely route of exposure and determined young children would not be at risk.
Although this evaluation found no harmful lead levels, CPSC staff is asking that voluntary standards be developed for synthetic turf to preclude the use of lead in future products.

The U.S. Consumer Product Safety Commission is charged with protecting the public from unreasonable risks of serious injury or death from more than 15,000 types of consumer products under the agency’s jurisdiction. Deaths, injuries and property damage from consumer product incidents cost the nation more than $800 billion annually. The CPSC is committed to protecting consumers and families from products that pose a fire, electrical, chemical, or mechanical hazard. The CPSC’s work to ensure the safety of consumer products – such as toys, cribs, power tools, cigarette lighters, and household chemicals – contributed significantly to the decline in the rate of deaths and injuries associated with consumer products over the past 30 years.
