Risk Phrases: 36/37/38
**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Irritating to eyes, respiratory system and skin.
Potential Health Effects
Eye:
Causes eye irritation. Effects may be delayed. Causes redness and
pain. May cause chemical conjunctivitis and corneal damage.
Skin:
Causes skin irritation. Causes redness and pain.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea.
Inhalation:
Causes respiratory tract irritation. Olfactory fatigue may occur.
Can produce delayed pulmonary edema. May cause central nervous
system effects such as nausea and headache.
Chronic:
Prolonged or repeated skin contact may cause dermatitis. Chronic
inhalation may cause effects similar to those of acute inhalation.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid.
Skin:
Flush skin with plenty of water for at least 15 minutes while
removing contaminated clothing and shoes. Get medical aid if
irritation develops or persists. Wash clothing before reuse.
Ingestion:
Never give anything by mouth to an unconscious person. Do NOT induce
vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls
of milk or water. Get medical aid if irritation or symptoms occur.
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 if cough or other symptoms appear. Do
NOT use mouth-to-mouth resuscitation.
Notes to Physician:
Treat symptomatically and supportively.
**** SECTION 5 - FIRE FIGHTING MEASURES ****
General Information:
Evacuate area and fight fire from a safe distance. As in any fire,
wear a self-contained breathing apparatus in pressure-demand,
MSHA/NIOSH (approved or equivalent), and full protective gear. During
a fire, irritating and highly toxic gases may be generated by thermal
decomposition or combustion. Dust can be an explosion hazard when
exposed to heat or flame. This material in sufficient quantity and
reduced particle size is capable of creating a dust explosion.
Flammable solid. May burn rapidly with flare burning effect. May
re-ignite after fire is extinguished.
Extinguishing Media:
Water spray may cause frothing. For large fires, use water spray,
fog or regular foam. Contact professional fire-fighters immediately.
For small fires, use dry chemical, carbon dioxide, sand, earth, water
spray or regular foam. Cool containers with flooding quantities of
water until well after fire is out.
**** 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. Scoop up with a nonsparking tool, then
place into a suitable container for disposal. Avoid generating dusty
conditions. Remove all sources of ignition. Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Minimize dust generation and accumulation. May
form flammable dust-air mixtures. Avoid contact with eyes, skin, and
clothing. Empty containers retain product residue, (liquid and/or
vapor), and can be dangerous. Keep container tightly closed. Keep
away from heat, sparks and flame. Use with adequate ventilation. Do
not pressurize, cut, weld, braze, solder, drill, grind, or expose
empty containers to heat, sparks or open flames.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances.
**** 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 general or
local explosion-proof ventilation to keep airborne levels to
acceptable levels.
Exposure Limits
CAS# 7704-34-9:
Russia: 6 mg/m3 TWA
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:
A respiratory protection program that meets OSHA's 29
CFR 1910.134 and ANSI Z88.2 requirements or European
Standard EN 149 must be followed whenever workplace
conditions warrant respirator use.
