**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Harmful if swallowed. Irritating to eyes, respiratory system and
skin. Contact with combustible material may cause fire.Hygroscopic
(absorbs moisture from the air).
Potential Health Effects
Eye:
May cause eye irritation. Causes eye irritation. May cause
chemical conjunctivitis.
Skin:
Causes skin irritation.
Ingestion:
May cause irritation of the digestive tract. May cause
methemoglobinemia, cyanosis (bluish discoloration of skin due to
deficient oxygenation of the blood), convulsions, and death.
Methemoglobinemia is characterized by dizziness, drowsiness,
headache, shortness of breath, cyanosis (bluish discoloration of
skin due to deficient oxygenation of the blood), rapid heart rate and
chocolate-brown colored blood. May be harmful if swallowed.
Inhalation:
Causes respiratory tract irritation. May cause methemoglobinemia,
cyanosis (bluish discoloration of skin due to deficient oxygenation
of the blood), convulsions, tachycardia, dyspnea (labored
breathing), and death.
Chronic:
Sodium nitrate may react with secondary or tertiary amines to form
nitrosamines (certain nitrosamines are cancer suspect agents).
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
In case of contact, immediately flush eyes with plenty of water for
at least 15 minutes. Get medical aid.
Skin:
In case of contact, immediately flush skin with plenty of water.
Remove contaminated clothing and shoes. Get medical aid. Wash
clothing before reuse.
Ingestion:
Call a poison control center. If swallowed, do not induce vomiting
unless directed to do so by medical personnel. Never give anything by
mouth to an unconscious person. Get medical aid.
Inhalation:
Remove from exposure and move to fresh air immediately. If not
breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical aid.
Notes to Physician:
**** SECTION 5 - FIRE FIGHTING MEASURES ****
General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. Strong oxidizer. Contact with other material may
cause fire. Wear appropriate protective clothing to prevent contact
with skin and eyes. Wear a self-contained breathing apparatus (SCBA)
to prevent contact with thermal decomposition products.
Extinguishing Media:
Use water only!
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Vacuum or sweep up material and place into a suitable disposal
container. Clean up spills immediately, observing precautions in the
Protective Equipment section. Avoid generating dusty conditions.
Provide ventilation. Keep combustibles (wood, paper, oil, etc.,) away
from spilled material.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Use with adequate ventilation.
Minimize dust generation and accumulation. Avoid contact with skin
and eyes. Empty containers retain product residue, (liquid and/or
vapor), and can be dangerous. Keep container tightly closed. Avoid
contact with clothing and other combustible materials. Avoid
ingestion and inhalation. Do not pressurize, cut, weld, braze,
solder, drill, grind, or expose empty containers to heat, sparks or
open flames.
Storage:
Do not store near combustible materials. Store in a tightly closed
container. Store in a cool, dry, well-ventilated area away from
incompatible substances. Avoid storage on wood floors.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate
ventilation to keep airborne concentrations low.
Exposure Limits
CAS# 7631-99-4:
Personal Protective Equipment
Eyes:
Wear appropriate protective eyeglasses or chemical
safety goggles as described by OSHA's eye and face
protection regulations in 29 CFR 1910.133 or European
Standard EN166.
Skin:
Wear appropriate protective gloves to prevent skin
exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
Follow the OSHA respirator regulations found in 29
CFR 1910.134 or European Standard EN 149. Use a
NIOSH/MSHA or European Standard EN 149 approved
respirator if exposure limits are exceeded or if
irritation or other symptoms are experienced.
