Foam insulation can have a negative effect on the environment. Some of the blowing agents used to spray some foam insulations utilize greenhouse gases, according to thomasnet.com. When they are sprayed, some foam sprays release harmful toxins into the atmosphere.
The toxic fumes released by spray foam insulation can be fatal if they are inhaled. A respirator should be worn at all times while spraying foam insulation or installing foam board installation.
Foam insulation can be dangerous even to the touch. It can be irritating if it comes in contact with the eyes and skin. Overexposure to foam insulation can even lead to temporary blindness.
Demolishing buildings that employed foam insulation in their construction can be tricky as explosions and wrecking balls can cause toxic foam insulation debris to become airborne. To ensure maximum safety, foam insulation should be removed delicately without breaking it.
Exposure to burning foam insulation can be especially fatal to living organisms. If it is inhaled, smoke from burning foam insulation can cause people to go blind or lose consciousness.
