4,4'-Methylene-bis(2-chloroaniline) (MOCA): Health effects
Description
This depends on how much methylene bis 2,4 aniline (MOCA) (4,4-) you have been exposed to, for how long, and your current state of health. Exposure can result in symptoms such as distress in the digestive system as well as burning of the skin, hands and face where direct contact has taken place. Methylene bis 2,4 aniline (MOCA) (4,4-) is probably a cancer-causing agent in humans. It can interfere with the ability of blood to carry oxygen and result in headaches, dizziness, nausea and result in a bluish colour in the lips and skin.
Entering the body
Direct contact with the skin, eyes and inhalation of dust and or other particles to which it is attached.
Exposure
People working in industries that produce or use the compound for manufacture of polyurethane products are most likely to be directly exposed to the compound. Exposure may take place where the compound has been disposed of in landfill or waste disposal sites.
Health guidelines
Worksafe Australia:
The compound is probably carcinogen to humans, can readily be absorbed through the skin. Time weighted average exposure levels over an 8-hour period should be limited to no more than 0.22 milligrams per cubic metre of air.
