Fire Fighting Procedures · 2건

Extinguish fire using agent suitable for type of surrounding fire. Material itself does not burn or burns with difficulty. Use water in flooding quantities as fog. Use "alcohol" foam, dry chemical, or carbon dioxide. Keep run-off water out of sewers and water sources.

Use flooding quantities of water as spray. Approach fire from upwind to avoid hazardous vapors & toxic decomposition products.

Storage ConditionsStore in a cool, dry, well-ventilated location. Separate from acids, oxidizing materials, halogens.

Disposal Methods · 1건

SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

Spillage DisposalPersonal protection: chemical protection suit including self-contained breathing apparatus. Do NOT wash away into sewer. Sweep spilled substance into covered containers.
Preventive Measures · 1건

SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.
