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 Safety Data Sheet (SDS) 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.
- Know what to do in an emergency situation. Call Campus Police at x5555, when necessary.
