NITRIC OXIDE

CAS: 10102-43-9

Fraction By Weight: 100.0%

Reports of Carcinogenicity:NTP:No IARC:No OSHA:No
Medical Cond Aggravated by Exposure:

First Aid: INHALATION: If adverse effects occur, remove to
uncontaminated area. Give artificial respiration if not breathing.
Get immediate medical attention. SKIN CONTACT: Wash skin with soap
and water for at least 15 minutes while removing contaminated
clothing and shoes. Get medical attention, if needed. Thoroughly
clean and dry contaminated clothing and shoes before reuse. EYE
CONTACT: Flush eyes with plenty of water for at least 15 minutes.
Then get immediate medical attention. INGESTION: If a large amount
is swallowed, get medical attention. ANTIDOTE: methylene blue,
intravenous; ascorbic acid, intravenous.

Extinguishing Media:water Do not use dry chemicals, carbon dioxide or
halogenated extinguishing agents. Large fires: Flood with fine
water spray.
Fire Fighting Procedures:Move container from fire area if it can be
done without risk. Cool containers with water spray until well
after the fire is out. Stay away from the ends of tanks. For fires
in cargo or storage area: If this is impossible then take the
following precautions: Keep unnecessary people away, isolate hazard
area and deny entry. Let the fire burn. For small fires, contain
and let burn.
Unusual Fire/Explosion Hazard:Negligible fire hazard. Oxidizer. May
ignite or explode on contact with combustible materials.

Spill Release Procedures:Stop leak if possible without personal risk.
Avoid contact with combustible materials. Keep unnecessary people
away, isolate hazard area and deny entry. Ventilate closed spaces
before entering. Notify Local Emergency Planning Committee and
State Emergency Response Commission for release greater than or
equal to RQ (U.S. SARA Section 304). If release occurs in the U.S.
and is reportable under CERCLA Section 103, notify the National
Response Center at (800)424-8802 (USA) or (202)426-2675 (USA).
Neutralizing Agent:

Handling and Storage Precautions:Store and handle in accordance with
all current regulations and standards. NFPA 430 Code for the
Storage of Liquid and Solid Oxidizing Materials. Keep separated
from incompatible substances. Notify State Emergency Response
Commission for storage or use at amounts greater than or equal to
the TPQ (U.S. EPA SARA Section 302). SARA Section 303 requires
facilities storing a material with a TPQ to participate in local
emergency response planning (U.S. EPA 40 CFR 355.30).
Other Precautions:

Respiratory Protection:The following respirators and maximum use
concentrations are drawn from NIOSH and/or OSHA. 100 ppm Any
supplied-air respirator. Any chemical cartridge respirator with a
full facepiece and cartridge(s) providing protection against this
substance. Only non-oxidizable sorbents are allowed (not charcoal).
Any powered, air-purifying respirator with cartridge(s) providing
protection against this substance. Only non-oxidizable sorbents are
allowed (not charcoal). Any air-purifying respirator with a full
facepiece and a canister providing protection against this
substance. Only non-oxidizable sorbents are allowed (not charcoal).
Any supplied-air respirator with a full facepiece. Any
self-contained breathing apparatus with a full facepiece. Escape -
Any air-purifying respirator with a full facepiece and a canister
providing protection against this substance. Only non-oxidizable
sorbents are allowed (not charcoal). Any appropriate escape-type,
self-contained breathing apparatus. For Unknown Concentrations or
Immediately Dangerous to Life or Health - Any supplied-air
respirator with full facepiece and operated in a pressure-demand or
other positive-pressure mode in combination with a separate escape
supply. Any self-contained breathing apparatus with a full
facepiece.
Ventilation:Provide local exhaust or process enclosure ventilation
system. Ensure compliance with applicable exposure limits.
Protective Gloves:Wear appropriate chemical resistant gloves.
Eye Protection:Wear splash resistant safety goggles. Provide an
emergency eye wash fountain and quick drench shower in the
immediate work area.
Other Protective Equipment:Wear appropriate chemical resistant
clothing.
