[Fire Fighting]

Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Extinguishing media: Use agent most appropriate to extinguish fire. In case of fire use water spray, dry chemical, carbon dioxide, or appropriate foam.
[Fire Potential]

Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.
[Ingestion]

Never give anything by mouth to an unconscious person. Get medical aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water.

[Handling]

Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation. Use with adequate ventilation.
[Inhalation]

May cause severe irritation of the respiratory tract with possible burns. Can produce delayed pulmonary edema.
[Skin]

May cause severe irritation and possible burns.
[Eyes]

Contact with eyes may cause severe irritation, and possible eye burns. Lachrymator. May cause chemical conjunctivitis.
