I HAVE taken a keen awareness and interest as to how hockey goalies stand or "crouch down" closer to the ice than most of their counterpart players when playing hockey. This in turn makes them more suceptible to vapor exposures because they spend more time closer to the ice surface (their face does-cause they are crouched down closer to the ice-and its the facial extremeties where we breathe for the most part)
The chemical formula compilation of what is known as "glycol" (HOOCH2CH2OH) comprises in most man-made ice hockey arena surfaces and in turn as the ice hockey ice playing surface gets used, it in turn melts and concentrated vapors form off the surface (water etc) and go into the ambient air right above the playing surface. The chemicals comprising glycol if breathed directly could cause epilepsy seizures??? More research needs to be effectively done just like when Dr. Irving Selikoff MD was able to link how asbestos caused mesopheleoma (cancer of the lungs) Not that I am saying glycol is a carcinogen but it could if ingested or breathed it might aide in causing the brain to react with a seizure-more tests by CDC need to be compiled for more data.
Currently the american CDC and NIOSH proposed "guideline" for exposure thresholds limits breathing of glycol is recommended at 50 ppm as its ceiling level
no data has come back reported from US Hockey as to how much glycol exposure goalies receive personally in an 8-hour period. To do so would they would need special collection pumps which could collect the glycol's parts per million. high or low volume personal air monitoring pumps collect this ambient air in a cartridge or balloon. To my knowledge, there is one hockey goalie who reports to US Hockey who could qualify for the studies to be performed on her body's breathing zone areas on and around the hockey goal-Chanda Gunn (US Womens Hockey Team Goalie)
Personally I just dont like leaving any stone unturned as to why epilepsy may occur in humans. inhaling of certain chemical toxins from the ambient air sometimes does unfortunately route into and through our lungs which in turn goes through the bloodstream and hits the brain to create internal injury. I like to prevent it if at all possible and I cant figure out why if it is known that an amateur hockey goalie who can be on the ice surface for hours at a time well, couldnt there be a breathing mask w/a cartridge attached manufactured invented so as to allow the breaths taken in air to become less likely to expose them to a chemical which could have potential of routing into their bloodstream for harm???
Point is please do be careful if/when you are in an area where glycol could be present "Antifreeze" in cars also contains glycol so if you have an antifreeze leak please do also be careful as to not getting yourself exposed to it if you by chance are seizure prone. see &read the accompanying Material Safety Data Sheets "MSDS" labels whenever possible which the manufacturer has printed online! they're very similar to those labels that accompany the prescription pills "package inserts"!!!
