  • 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.

  • Do not eat, drink or smoke in work areas.
  • Make sure the emergency eye wash is accessible and in good working condition.
