WAYS PHOTO LAB PERSONNEL COULD BECOME POISONED WHEN WORKING WITH
PHOTOGRAPHIC CHEMICALS.
When working around chemicals, precaution should be taken to prevent poisoning. There are
three ways photographic personnel can become poisoned:
(1) INGESTION - The taking of chemicals into the digestive system by using beakers or similar
vessels as drinking cups. Also by contamination of cups from chemicals. Don't mix chemicals in
vessels used by personnel for drinking purposes.
(2) INHALATION - The taking of chemicals into the respiratory system by breathing of fumes,
mist, or dust. Wear protective breathing apparatus when working with chemicals. Keep adequate
ventilation in the area at all times and use fans or other devices when mixing chemicals.
(3) SKIN CONTACT - The most likely means of poisoning. Be aware of antidotes for
chemicals you are using and follow recommended procedures with even the slightest contact.
