**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Toxic by inhalation and in contact with skin. Very toxic if
swallowed. Causes burns. May cause sensitization by skin contact.The
toxicological properties of this material have not been fully
investigated.Lachrymator (substance which increases the flow of
tears).Corrosive.
Potential Health Effects
Eye:
Causes eye burns. Lachrymator (substance which increases the flow
of tears). May cause corneal edema and inflammation.
Skin:
Causes skin burns. Toxic in contact with skin. Skin contact may
cause an allergic skin reaction (sensitization) in a small
proportion of individuals.
Ingestion:
May be fatal if swallowed. May cause burns to the digestive tract.
May cause nausea and vomiting.
Inhalation:
Irritation may lead to chemical pneumonitis and pulmonary edema.
Toxic if inhaled. Causes respiratory tract irritation with possible
burns.
Chronic:
Laboratory experiments have resulted in mutagenic effects.
**** 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
immediately. 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.
Discard contaminated clothing in a manner which limits further
exposure.
Ingestion:
POISON material. If swallowed, get medical aid immediately. Only
induce vomiting if directed to do so by medical personnel. Never give
anything by mouth to an unconscious person.
Inhalation:
Remove from exposure and move to fresh air immediately. 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:
**** 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. Dusts at sufficient concentrations can form
explosive mixtures with air. During a fire, irritating and highly
toxic gases may be generated by thermal decomposition or combustion.
Will burn if involved in a fire.
Extinguishing Media:
Use water spray, dry chemical, carbon dioxide, or appropriate foam.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Clean up spills immediately, observing precautions in the Protective
Equipment section. Sweep up, then place into a suitable container for
disposal. Avoid generating dusty conditions. Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. Minimize dust
generation and accumulation. Do not get in eyes, on skin, or on
clothing. Keep container tightly closed. Avoid ingestion and
inhalation.
Storage:
Keep refrigerated. (Store below 4C/39F.) Store in a tightly closed
container. Store in a dry area. Store protected from light. Store
under nitrogen. Refrigeration has been recommended to prolong
integrity of the product.
**** 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# 128-53-0:
Personal Protective Equipment
Eyes:

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.
