7.12 Plaster of Paris
When mixed with water, this material hardens and then slowly becomes hot – temperatures as high as 60˚C.
NEVER attempt to make a cast enclosing any part of the body using this material.
Failure to follow this instruction can cause severe burns that may require surgical removal of affected tissue
or amputation of limb.
Direct, prolonged or repeated contact with the skin may cause irritation and attempts at removal can result in
abrasions. Rinse with water until free of material to avoid abrasions, then wash skin thoroughly with mild soap
and water.
If Plaster of Paris is in contact with eyes, first rinse with plenty of water for several minutes (remove contact
lenses if easily possible), then take to a doctor.
Plaster of Paris dust needs to be controlled as it is an irritant that can cause usually mild breathing
difficulties.
