Avoid runoff into storm sewers and ditches which lead to waterways. Clean up spills immediately, using the appropriate protective equipment. Sweep up or absorb material, then place into a suitable clean, dry, closed container for disposal. Avoid generating dusty conditions. Provide ventilation.
Stable under normal temperatures and pressures. Easily tarnishes in moist air.
Oxidizing agents, acids, potential explosion with hydrogen peroxide and hydrochloric acid, violent reaction with halogens, forms amalgam with aluminum alloys.
Nature of decomposition products unknown..
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. To extinguish fire, use water fog, dry chemical, carbon dioxide, or regular foam. Use agent most appropriate to extinguish fire. Do not direct water at the heated material.
Non-combustible, substance itself does not burn but may react upon heating to produce corrosive and/or toxic fumes. Runoff may pollute waterways.
Fire will produce irritating, corrosive and/or toxic gases.
May cause gastrointestinal irritation with nausea, vomiting and diarrhea. May cause bone marrow depression.
May cause respiratory tract irritation. May cause burns to the respiratory tract.
May cause severe irritation and possible burns. May cause dermatitis.
Contact with eyes may cause severe irritation, and possible eye burns.
If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately.
Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
