WPI Darkroom Safety: Photographic Chemicals

Most common photographic chemicals can be used safely if simple pre- cautions are followed. The following safety tips are applicable to most aqueous chemicals used in black-and-white and color photography. Always read the Material Safety Data Sheet (MSDS) for a specific chemical before use.

Avoid creating dust when mixing dry chemicals. Use pre-mixed chemicals when available.
Ensure good ventilation in photographic work rooms.
Protect yourself by wearing eye protection and gloves whenever you work with chemicals. Most photochemicals are corrosive.
Use the least toxic chemicals available; avoid cyanides, heavy metals.
When mixing water and acid, always add the acid to the water to prevent violent splashing.
Dispose of chemical wastes properly. Almost all photographic chemicals must be disposed of as hazardous waste.
Always wash hands after using chemicals and before eating, drinking or smoking.
Do not eat, drink or smoke in work areas.
Make sure the emergency eye wash is accessible and in good working condition.
