Safety stan­dards set for school tracks, turf

China Daily (Canada) - - NEWS CAPSULE -

Safe lim­its of dan­ger­ous chem­i­cals emit­ted by syn­thetic run­ning tracks, play­grounds and ar­ti­fi­cial turf have been spec­i­fied for the first time in new stan­dards for schools in Zhe­jiang prov­ince.

Stu­dents at sev­eral pri­mary and mid­dle schools fell ill and the syn­thetic ma­te­ri­als used for the run­ning tracks and ar­ti­fi­cial grass were sus­pected cul­prits.

Sum­mer heat has been cited as a pos­si­ble cause of in­creased chem­i­cal emis­sions from syn­thetic ma­te­ri­als. Un­der the stan­dards, a group of five teach­ers, par­ents and ex­perts will as­sess odors at school fa­cil­i­ties reg­u­larly.

They will rate odors on a 1-5 scale, with 1 mean­ing no odor and 5 sig­ni­fy­ing strong, pun­gent odor. If three of the five reach a con­sen­sus at 3 or above, the run­ning track will be closed.
