Important Information Before You Begin

  • Observe the precautionary information on the containers.

  • Use ventilation with enough air circulation or exhaust to keep the mixing area free from strong odors (change 10 room-volumes of air per hour).

  • Wear rubber gloves, eye protection (visor goggles or face shield), and a chemically impervious apron when mixing chemicals.

  • To avoid release of irritating vapor(s), always follow mixing instructions.

Storage Conditions

Important: Store at 40°-80°F (4.5°-26.5°C). This solution is highly concentrated. If stored in a cold area, crystals may be deposited. If the fixer crystallizes, it should be discarded.
