**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Contact with acids liberates toxic gas. Causes burns. Very toxic to
aquatic organisms.Corrosive.Hygroscopic (absorbs moisture from the
air).Air sensitive.Light sensitive.
Potential Health Effects
Eye:
Causes eye burns. May cause irreversible eye injury. May cause
blindness. May cause chemical conjunctivitis and corneal damage.
Skin:
Causes skin burns. Prolonged and/or repeated contact may cause
irritation and/or dermatitis. May cause skin rash (in milder cases),
and cold and clammy skin with cyanosis or pale color.
Ingestion:
May cause severe and permanent damage to the digestive tract. May
cause perforation of the digestive tract. May cause cardiac
disturbances. Causes severe pain, nausea, vomiting, diarrhea, and
shock. Causes digestive tract burns with immediate pain, swelling of
the throat, convulsions, and possible coma. May cause systemic
effects.
Inhalation:
Irritation may lead to chemical pneumonitis and pulmonary edema.
Causes severe irritation of upper respiratory tract with coughing,
burns, breathing difficulty, and possible coma. May cause effects
similar to those described for ingestion. Aspiration may lead to
pulmonary edema. May cause systemic effects.
Chronic:
Effects may be delayed.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Get medical aid immediately. Do NOT allow victim to rub eyes or keep
eyes closed. Extensive irrigation with water is required (at least 30
minutes).
Skin:
Get medical aid immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
and shoes. Wash clothing before reuse. Destroy contaminated shoes.
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:
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. If breathing is difficult, give oxygen. 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:
**** 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. 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. Dusts may be combustible
when exposed to heat, flame, or oxidizing agents. This material does
not have a flashpoint. It can burn but does not ignite readily.
Fire may produce highly irritating or toxic gases (sulfur dioxide and
hydrogen sulfide).
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or
alcohol-resistant foam.
**** 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. Avoid runoff into storm sewers and ditches which lead to
waterways. Clean up spills immediately, observing precautions in the
Protective Equipment section. Avoid generating dusty conditions.
Remove all sources of ignition. Flush spill area with water. Provide
ventilation. Restrict access to area until completion of clean-up.
Ensure clean-up is conducted by trained personnel only.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Wash hands before eating. Use only
in a well-ventilated area. Do not breathe 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. Discard contaminated shoes.
Storage:
Keep away from heat, sparks, and flame. Keep container closed when
not in use. Keep from contact with oxidizing materials. Keep away
from strong acids. Corrosives area.
**** 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# 1313-84-4:
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:
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.

**** SECTION 10 - STABILITY AND REACTIVITY ****
Chemical Stability:
Air sensitive. Light sensitive. Hygroscopic: absorbs moisture or
water from the air. Moderately stable. Aqueous solutions and moist
solid slowly give off Hydrogen sulfide gas; more Hydrogen sulfide is
given off it heated. Aqueous solutions are slowly oxidized on
exposure to air. Discolours on exposure to light and air.
Conditions to Avoid:
Light, moisture, exposure to air, acids.
Incompatibilities with Other Materials:
Acids-reaction releases highly toxic and flammable Hydrogen sulfide.
Oxidizing agents-Can react violently and form highly irritating
Sulfur dioxide. Diazonium salts react explosively.
N,N-Dichloromethyl amine reacts explosively. Carbon releases heat.
Hazardous Decomposition Products:
Oxides of sulfur, hydrogen sulfide.
Hazardous Polymerization: Has not been reported.
