One person works, while the other stands by to make sure the worker is not receiving fumes due to a defective filter in the mask. The person mopping up the spill takes towels, rays, mesh bags, blankets, even clothes if necessary, to soak up the spill, puts them immediately in the dry cleaning machine and shuts the door. He or she must be careful not to let the perc come in contact with exposed skin. If anyone does pass out from the fumes, get them outside into the air as quickly as possible. Some toxic effects come from repeated exposure, over a long period of time.
Chemicals can enter the body and gradually produce poisoning.
This kind of poisoning occurs because the exposure is repeated day after day over many years. The government wants to protect your health, and has put legislation in place to do it. When the legislation became law, every employer was required to hold training sessions to tell employees about the MSDS sheets and where they were kept. If you were hired after this time, it is possible this training has not been repeated. It is your right as a Canadian worker to ask about the MSDS sheets, be given a chance to read them, and an opportunity to ask management for further information if necessary.
