:::
:
:

Water spray
Foam, Dry powder, Do not use a heavy water stream.
May intensify fire; oxidizer.
May induce explosion of containers by heating.
In case of fire, product may produce irritative or toxic fumes/gases.

:

Protection during firefighting:

If ignited, for the initial fire-fighting, cut off combustion sources, extinguishfire at a stroke using appropriate fire-extinguishers.
In the case of peripheral fire, quickly remove movable containers to safe
places.
If unable to be moved containers, sprinkle water to containers andsurrounding equipment, etc. to cool.
Even after extinguishing fire, thoroughly cool containers by using plenty ofwater.
Wear appropriate fire-resistant clothing including self containedcompressed air breathing apparatus.

5. Fire fighting measures

6. Accidental release measures
Personal Precautions, Protective Equipment and Emergency Procedures
General measures: Before entering, ventilate the area.
Do not let unauthorized persons come close to the area.
Immediately place the leakage area in isolation, with taking proper
distances for all directions.
Wear appropriate personal protective devices to prevent inhalation andcontact with eye, skin, and clothing, and never attempt to work on the lee.
Environmental precautions
Environmental precautions:

Avoid release to the environment.
Prevent entry to sewers and public waters.

Methods and Equipment for Containment and Cleaning up
Methods for cleaning up: Clean up any spills as soon as possible, using an absorbent material tocollect it.
Collect leaking and spilled liquid in sealable containers as far as possible.
Wash out the spilled area with large amounts of water.

When involved in a fire, may cause an explosion. Leakage andsubsequent evaporation of the water of the solutions may present
increased dangers as follows: 1. in contact with combustible material(particularly with fibrous material such as jute, cotton or sisal) orsulphur, danger of spontaneous combustion; 2. in contact withammonium compounds, powdered metals or oils, danger of explosion.
Transport of ammonium nitrites, aqueous solution is prohibited.
