FLUOROELASTOMERS (Synthetic Rubber)
Many 'O' rings, seals, hoses, flexible pipes and other similar which appear to be manufactured from natural rubber are, in fact, made of synthetic materials called Fluoroelastomers.
Under normal operating conditions, these materials are safe and do not constitute a health hazard. However, if the materials are damaged by burning or exposure to excessive heat, they can break down and produce highly corrosive hydrofluoric acid.
WARNING:
Contact with hydrofluoric acid can cause serious burns on contact with the skin. If skin contact does occur, carry out the following steps immediately:
Remove any contaminated clothing.
SEEK IMMEDIATE MEDICAL ATTENTION
Irrigate affected area of skin with copious amounts of cold water or limewater for 15 to 60 minutes.
