**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Harmful if swallowed. Contact with acids liberates toxic gas. May
cause fire.Heat sensitive.
Potential Health Effects
Eye:
May cause lacrimation (tearing), blurred vision, and photophobia.
May cause chemical conjunctivitis and corneal damage.
Skin:
May cause skin irritation and possible burns.
Ingestion:
May cause nausea, vomiting, abdominal pain, and increased
salivation.
Inhalation:
Inhalation of dust may cause respiratory tract irritation. Olfactory
fatigue may occur.
Chronic:
No information found.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid
immediately.
Skin:
Get medical aid if irritation develops or persists. Wash clothing
before reuse. Flush skin with plenty of soap and water.
Ingestion:
Do not induce vomiting. If victim is conscious and alert, give 2-4
cupfuls of milk or water. Never give anything by mouth to an
unconscious person. Get medical aid immediately.
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. Do NOT use mouth-to-mouth
resuscitation.
Notes to Physician:
**** 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. Use water spray to keep fire-exposed
containers cool. Use water with caution and in flooding amounts.
Combustible solid. May decompose explosively when heated or involved
in a fire. Powerful reducing agent. Closed containers may rupture
violently when heated. Heats spontaneously in contact with air,
especially moist air, and may ignite surrounding combustible
materials.
Extinguishing Media:
Use dry sand or earth to smother fire. If water is the only media
available, use in flooding amounts.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Sweep up or absorb material, then place into a suitable clean, dry,
closed container for disposal. Scoop up with a nonsparking tool,
then place into a suitable container for disposal. Avoid generating
dusty conditions. Remove all sources of ignition. Place under an
inert atmosphere. Do not get water inside containers. Control runoff
and isolate discharged material for proper disposal.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Use only in a well-ventilated area. Minimize dust generation and
accumulation. Avoid contact with eyes, skin, and clothing. Empty
containers retain product residue, (liquid and/or vapor), and can be
dangerous. Keep away from heat, sparks and flame. Avoid ingestion and
inhalation. Handle under an inert atmosphere. Store protected from
air. Do not allow contact with water. Do not pressurize, cut, weld,
braze, solder, drill, grind, or expose empty containers to heat,
sparks or open flames. Keep from contact with moist air and steam.
Storage:
Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances. Do not expose
to air. Store protected from moisture. Store under an inert
atmosphere. Isolate from oxidizing materials and acids. Should not be
exposed to temperatures above 122F (50C). Do not store in an area
equipped with emergency water sprinklers. Consider equipping storage
facilities with sulfur dioxide detectors.
**** 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# 7775-14-6:
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.
