Chemical (CAS#)

Difluoroethane (75-37-6)

Classification

  • Flammable Gas

Formula

C2H4F2

Characteristics

1,1-Difluoroethane is colorless, odorless gas shipped as a liquefied gas under its vapor pressure. Contact with the liquid can cause frostbite. It is easily ignited. Its vapors are heavier than air and a flame can travel back to the source of leak very easily. This leak can be either a liquid or vapor leak. It can asphyxiate by the displacement of air. Under prolonged exposure to fire or heat the containers may rupture violently and rocket.

Treatment

Pressurized cylinder can be used for vapor reduction.

Mechanism/Byproduct

Adsorption

Primary Mechanism Type

Adsorption

Byproduct

Compound mixed with MgO, TiO2, Mg(OH)2

Disposal Notes

The treated residue always needs to be disposed of in accordance to local, state and federal regulations.  For U.S. federal regulations follow 40 CFR 261, Subpart C “Characteristic Hazardous Wastes” and 40 CFR 261, Subpart D “Listed Hazardous Wastes”.

Reaction Rate (Slower to Faster)

Reaction Rate: 3

Summary




**Treatment: Pressurized cylinder can be used for vapor reduction if under flammability and explosive levels.

FAST-ACT Application Methods:

Situations:

A. For trace liquid chemical contamination, apply FAST-ACT Powder from either a shaker or pail to the surface to fully absorb the compounds. Apply powder forming a ring around the hazard and then shake the powder directly onto hazard to thoroughly cover the liquid. Carefully Agitate all the powder to ensure all liquid has been adsorbed.

B. Alternatively, for trace contamination on a surface, you can utilize a FAST-ACT Decon Mitt. Tear packet at the notch and remove the FAST-ACT Decon Mitt. Unfold mitt and insert hand, tightening the strap. Decontaminate surface by rubbing with pad side to remove liquid contamination. Shake and pat the mitt to release powder from the mitt to the surface. If liquid contamination is still present or suspected, repeat process with a new FAST-ACT Decon Mitt.

C. For liquid contamination, directly apply the FAST-ACT Powder from a Shaker or Pail to the liquid to fully absorb the compound ensuring no liquid chemical remains. Apply powder forming a ring around the hazard and then shake the powder directly onto hazard to thoroughly cover the liquid. Carefully agitate all the powder to ensure all liquid has been adsorbed.

D. For vapor contamination, utilize a FAST-ACT Pressurized Cylinder to dispense the product into the airspace: 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.
