(2) The presence of oxygen, ether, mineral or vegetable oils, phenols,
cresols, terpenes, hydrocarbon solvents, chlorinated hydrocarbons, esters, or oxidizing
acids will hasten the deterioration process. Check rubber articles often for swelling,
tackiness, or cracking. When any of these conditions exist, replace the affected parts.
(3) You can prolong the useful life of rubber articles by following a program
of intelligent use and care. Carry out the following suggestions when possible.
(a) If removal is required, remove the metal connectors immediately
(b) When possible, store rubber articles in the dark. Store them away
from sources of ozone generation such as fluorescent lighting fixtures, electric motors,
and diathermy machines.
(c) To prevent tackiness, sprinkle a powder on rubber articles to be
stored or steam sterilized that will come into immediate contact with each other. For
this purpose, you may use talc, zinc stearate, or starch. Avoid contaminating the
respiratory tract with these substances.
