**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Limited evidence of a carcinogenic effect.
Potential Health Effects
Eye:
Contact with eyes may cause severe irritation, and possible eye
burns. At high concentrations may cause lacrimation (tearing) and
irritation.
Skin:
May be absorbed through the skin. Causes irritation with burning
pain, itching, and redness. Prolonged exposure may result in skin
burns.
Ingestion:
Causes gastrointestinal irritation with nausea, vomiting and
diarrhea. May cause central nervous system depression, characterized
by excitement, followed by headache, dizziness, drowsiness, and
nausea. Advanced stages may cause collapse, unconsciousness, coma
and possible death due to respiratory failure.
Inhalation:
Inhalation of high concentrations may cause central nervous system
effects characterized by nausea, headache, dizziness, unconsciousness
and coma. May cause narcotic effects in high concentration. May cause
dizziness, incoordination, and unconsciousness. Central nervous
system effects may include confusion, ataxia (failure of muscular
coordination), vertigo, tinnitus, weakness, disorientation, lethargy,
drowsiness, and finally coma. May cause blood changes. Overexposure
may cause an increase in carboxyhemoglobin levels in the blood. Can
produce delayed pulmonary edema.
Chronic:
Possible cancer hazard based on tests with laboratory animals.
Prolonged or repeated skin contact may cause dermatitis. May cause
reproductive and fetal effects. Laboratory experiments have resulted
in mutagenic effects. Chronic exposure may cause lung, liver, and
pancreatic tumors. May cause conjunctivitis and/or corneal burns.
**** 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. Do
NOT allow victim to rub eyes or keep eyes closed.
Skin:
Get medical aid. Immediately flush skin with plenty of water for at
least 15 minutes while removing contaminated clothing and shoes.
Wash clothing before reuse.
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.
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. If breathing has ceased apply artificial respiration
using oxygen and a suitable mechanical device such as a bag and a
mask.
Notes to Physician:
Treat symptomatically and supportively.
**** 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. 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. Vapors mixed with air in
proper proportion will propagate a flame. Vapors may be heavier than
air. They can spread along the ground and collect in low or confined
areas. Containers may explode when heated. Combustible material; may
burn but does not ignite readily. Will form explosive mixtures in
atmospheres having high oxygen contents.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, or water spray.
For large fires, use dry chemical, carbon dioxide, alcohol-resistant
foam, or water spray. 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:
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container. Avoid runoff into storm sewers and
ditches which lead to waterways. Clean up spills immediately,
observing precautions in the Protective Equipment section. Remove all
sources of ignition. Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. Loosen closure
cautiously before opening. Avoid breathing dust, vapor, mist, or
gas. Do not get in eyes, on skin, or on clothing. Keep container
tightly closed. Keep away from heat, sparks and flame. Do not ingest
or inhale.
Storage:
Keep away from heat, sparks, and flame. Store in a tightly closed
container. Keep from contact with oxidizing materials. Store in a
cool, dry, well-ventilated area away from incompatible substances.
Keep away from metals. Store below 40C. Keep away from active
metals.
**** 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 exhaust ventilation to keep airborne concentrations below the
permissible exposure limits.
Exposure Limits
CAS# 1665-00-5:
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

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.
