First aid and notes for physicians: no specific antidote. Treatment of exposure should
be directed at the control of symptoms and the condition of the patient.
5. Fire fighting measures
Suitable extinguishing media: Water, foam, chemical power and carbon dioxide.
Unsuitable extinguishing media: None Hazardous combustion products: Carbon
monoxide, carbon dioxide, products from incomplete combustion, nitrogen oxides,
acrid fumes and toxic gases. Special hazards in fire: During emergency conditions
exposure to thermal decomposition products may cause a health hazard. Use of
NIOSH approved self contained breathing apparatus is recommended. When required
special protective equipment for fire-fighters: Protective clothes and gas mask.
6. Accidental release measures
Personal precautions: There is no actual hazardous of the Hypalon. The release is not
applicable. Environmental precautions: Clean the floor immediately and reuse the
clean powder. Drop the dirty part to the waste treatment center. Methods for cleaning:
Sweep the floor.
7. Handling and storage
Handling: provided good ventilation and/or local exhaust systems are used. Avoid
prolonged or repeated contact with skin. Use good personal hygiene. Do not consume
or store food in the work area. Wash hands before smoking or eating. Take
precautionary measures against static discharges. Electrically bond and ground all
containers and equipment before transfer or use of material.
Storage: Store in a cool, dry place. Minimize sources of ignition, such as static
build-up, heat, spark or flame.
