**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Irritating to eyes, respiratory system and skin. Harmful by
inhalation.Light sensitive.
Potential Health Effects
Eye:
May cause eye irritation.
Skin:
May cause skin irritation. Prolonged and/or repeated contact may
cause irritation and/or dermatitis.
Ingestion:
May cause irritation of the digestive tract. May cause liver and
kidney damage. 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:
May cause respiratory tract irritation. May cause effects similar to
those described for ingestion.
Chronic:
Chronic exposure can lead to iodism characterized by salivation,
nasal discharge, sneezing, conjunctivitis, fever, laryngitis,
bronchitis, stomatitis, and skin rashes.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. If irritation
develops, 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:
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 if cough or other symptoms appear.
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. 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. Containers may explode in
the heat of a fire. Vapors may be heavier than air. They can spread
along the ground and collect in low or confined areas.
Extinguishing Media:
Use foam, dry chemical, or carbon dioxide. Use agent most
appropriate to extinguish fire. 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:
Neutralize spill with sodium bicarbonate. Remove all sources of
ignition. Absorb spill using an absorbent, non-combustible material
such as earth, sand, or vermiculite. Do not use combustible
materials such as sawdust. Carefully scoop up and place into
appropriate disposal container. Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. Do not get on skin
or in eyes. Do not ingest or inhale. Store protected from light.
Storage:
Store in a cool, dry, well-ventilated area away from incompatible
substances. Store in opaque, air-tight containers.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use adequate general or local exhaust ventilation to keep airborne
concentrations below the permissible exposure limits.
Exposure Limits
CAS# 75-11-6:
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 impervious gloves.
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.
