Hazards and Protection.
Storage
Keep in a cool, dry location with ventilation and away from incompatible materials. Keep container tightly closed.
Handling
Electrically ground all equipment when handling. Do not use pressure to empty containers. Do not get in eyes, on skin or on clothing.
Protection
Protective clothing, PVC gloves when spraying fusilade 4e. Also, apron and full face shield when handling or mixing concentrate.
Respirators
NIOSH approved respirator for emission. May be a full face plate, half mask air purifying cartidge respirator for organic vapors and mists or a SCBA in pressure demand mode, supplied air respirator.
Small spills/leaks
Wear protective equipment. For small spills, mop up and place in an approved waste container. For larger spils, dike and then pump into an approved container.
Stability
Stable for 3 yr at 25 C and for 6 months at 37 C. Reasonably stable in acidic and neutral conditions, but rapidly hydrolyzed in alkaline media (ph 9). Tested stable in storages 40-120 F (5-50 C).
Incompatibilities
Strong oxidizing agents.
Decomposition
Oxides of carbon and nitrogen, ammonia.
