Special protective equipment and precautions for fire fighters

Not considered to be a fire hazard. Not considered to be an explosion hazard. In the event of a fire, wear full protective clothing and NIOSH approved self-contained breathing apparatus with full face piece operated in the pressure demand or other positive pressure mode.

6. Accidental Release Measures

Personal precautions, protective equipment and emergency procedures: Evacuate area. Wear self-contained breathing apparatus, rubber boots, and heavy rubber gloves.
Environmental precautions: Not available.
Methods and materials for containment and clean up: Ventilate area of leak or spill. Clean-up personnel may require respiratory protection from dust. Spills: Sweep up and containerize for reclamation or disposal. Vacuuming or wet sweeping may be used to avoid dust dispersal.

7. Handling and Storage

Precautions for safe handling: Do not breathe dust. Avoid contact with eyes, skin, and clothing. Avoid prolonged or repeated exposure. Wash thoroughly after handling.
Conditions for safe storage: Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Isolate from incompatible substances.

8. Exposure Controls / Personal Protection

Exposure Standards

Material	TWA ppm	TWA mg/m³	STEL ppm	STEL mg/m³
Malachite Green	-	-	-	-

Engineering controls: Facilities storing or utilising this material should be equipped with an eyewash facility and safety shower. Use adequate ventilation to keep airborne concentrations low. A local exhaust system which captures the contaminant at its source is recommended to prevent dispersion of the contaminant into the workroom air.

Personal protective equipment

Eye and face protection: Use chemical safety goggles. Contact lenses should not be worn when working with this material. Maintain eye wash fountain and quick-drench facilities in work area.
Skin protection: Wear protective gloves. 0.11mm thick nitrile.
Body protection: Wear a clean body-covering clothing.
Respiratory protection: For conditions of use where exposure to the dust is apparent, a dust/mist respirator may be worn. For emergencies, a self-contained breathing apparatus may be necessary.
