Floor Rubber
Observe extra great care when it is suspected that you may
have to handle floor rubber.
Certain seals which have to withstand high operating
temperatures (e.g. in engines, transmissions, axles, hydraulic
motors and pumps) may be made from floor rubber, which,
when exposed to high heat (fire), forms hydrogen fluoride
and hydrofluoric acid. This acid is very corrosive and cannot
be rinsed or washed off from the skin. It causes very severe
burns which take a long time to heal.
It usually means that damaged tissue must be surgically
removed. Several hours may pass after contact with the
acid, before any symptoms appear and therefore one is not
given any immediate warning. The acid may remain on the
machine parts for several years after a fire.
If swelling, redness or a stinging feeling appears and one
suspects that the cause may be contact with heated floor
rubber, contact a medical doctor immediately. If a machine,
or part of a machine, has been exposed to fire or severe
heat, it must be handled by specially trained personnel. In
all handling of machines after a fire, thick rubber gloves and
effective goggles must be used.
The area around a part which has been very hot and which
may be made of floor rubber must be decontaminated by
thorough and ample washing with lime water (a solution or
suspension of calcium hydroxide, i.e. slaked lime in water).
After the work has been completed, gloves must be washed
in lime water and then discarded.
