Nitric Oxide
Specific hazards arising : Contains gas under pressure. Oxidizing material. This material increases the risk of
from the chemical fire and may aid combustion. Contact with combustible material may cause fire. In a
fire or if heated, a pressure increase will occur and the container may burst or explode.
Hazardous thermal : Decomposition products may include the following materials:
decomposition products nitrogen oxides
Special protective actions : Promptly isolate the scene by removing all persons from the vicinity of the incident if
for fire-fighters there is a fire. No action shall be taken involving any personal risk or without suitable
training. Contact supplier immediately for specialist advice. Move containers from fire
area if this can be done without risk. Use water spray to keep fire-exposed containers
cool. If involved in fire, shut off flow immediately if it can be done without risk.
Special protective : Fire-fighters should wear appropriate protective equipment and self-contained breathing
equipment for fire-fighters apparatus (SCBA) with a full face-piece operated in positive pressure mode.

Environmental precautions : Ensure emergency procedures to deal with accidental gas releases are in place to avoid
contamination of the environment. Inform the relevant authorities if the product has
caused environmental pollution (sewers, waterways, soil or air).
Conditions for safe storage, : Store in accordance with local regulations. Store in a segregated and approved area.
including any Store away from direct sunlight in a dry, cool and well-ventilated area, away from
incompatibilities incompatible materials (see Section 10). Cylinders should be stored upright, with valve
protection cap in place, and firmly secured to prevent falling or being knocked over.
Cylinder temperatures should not exceed 52 °C (125 °F). Store locked up. Separate
from reducing agents and combustible materials. Store away from grease and oil.
Keep container tightly closed and sealed until ready for use. See Section 10 for
incompatible materials before handling or use.

Nitric Oxide
Appropriate engineering : Use only with adequate ventilation. Use process enclosures, local exhaust ventilation or
controls other engineering controls to keep worker exposure to airborne contaminants below any
recommended or statutory limits.
Environmental exposure : Emissions from ventilation or work process equipment should be checked to ensure
controls they comply with the requirements of environmental protection legislation. In some
cases, fume scrubbers, filters or engineering modifications to the process equipment
will be necessary to reduce emissions to acceptable levels.
