Summary
FAST-ACT Application Methods:
Situations:
D. For vapor contamination, utilize a FAST-ACT Pressurized Cylinder to dispense the product into the air space: Shake the FAST-ACT Pressurized Cylinder to loosen the contents. Pull the ring pin. Squeeze the lever and shake the cylinder in up and down motion to ensure maximum discharge of the FAST-ACT powder. Aim the hose and mist all powder in the direction of hazard. If liquid hazard is also present, sweep hose side to side to ensure complete coverage of liquid hazard.
F. Extreme caution. Compound is spontaneously combustible.
