shipment
Glues are used to seal containers and attach labels
Sometimes leaks can develop in the load, causing
hazardous chemicals to drain to the back of the truck
Often quick-drying agents are used to package
products for shipment. Some of these agents contain
Isocyanates, which are a designated substance in
Ontario
If the agents are not used and maintained properly,
workers may be exposed to the Isocyanates
Isocyanates are also contained in some floor repair
epoxies

asthma, damage to lungs, burns, irritation to your respiratory tract, skin, eyes
