Hazards and Protection.
Storage
Keep tightly closed in a cool place in a tightly closed container.
Handling
Containers of this material may be hazardous when emptied. Since emptied containers retain product residues (vapor, liquid, and/or solid), all hazard precautions given in the data sheet must be observed.
Protection
Chemical splash goggles in compliance with OSHA regulations are advised; however, OSHA regulations also permit other type safety glasses. Wear resistant gloves such as: natural rubber, To prevent repeated or prolonged skin contact, wear impervious clothing and boots.
Respirators
If overexposure has been determined or documented, a NIOSH/MSHA jointly approved air supplied respirator is advised in absence of proper environmental control. OSHA regulations also permit other NIOSH/MSHA respirators under specified conditions.
Small spills/leaks
Small Spill - Absorb liquid on vermiculite, floor absorbent or other absorbent material. Large Spill - Prevent run-off to sewers, streams or other bodies of water. If run-off occurs, notify proper authorities as required, that a spill has occurred. Persons not wearing protective equipment should be excluded from area of spill until clean-up has been completed. Stop spill at source, dike area of spill to prevent spreading, pump liquid to salvage tank. Remaining liquid may be taken up on sand, clay, earth, floor absorbent, or other absorbent material and shoveled into containers.

Fire fighting
Extinguish fire using regular foam, water fog, carbon dioxide, dry chemical. Water or foam may cause frothing which can be violent and possibly endanger the life of the firefighter. Water may be used to keep fire-exposed containers cool until fire is out. Wear a self-contained breathing apparatus with a full facepiece operated in the positive pressure demand mode with appropriate turn-out gear and chemical resistant personal protective equipment.
Hazards
Toxic oxides of nitrogen may form in fire.
Combustion products
Toxic oxides of nitrogen may form in fire.

Health.
Exposure effects
   Ingestion
Swallowing small amounts of this material during normal handling is not likely to cause harmful effects. Swallowing large amounts may be harmful.
   Inhalation
Ingestion causes mild irritation of mouth and stomach. Contact with liquid causes irritation of eyes and (on prolonged contact) mild irritation of skin.
