EMERGENCY OVERVIEW
Possible risk of harm to the unborn child.
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation. A single prolonged skin exposure is not
likely to result in the material being absorbed in harmful amounts.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea.
Inhalation:
May cause respiratory tract irritation.
Chronic:
Prolonged or repeated skin contact may cause defatting and
dermatitis. Possible risk of harm to the unborn child.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
In case of contact, immediately flush eyes with plenty of water for
at least 15 minutes. Get medical aid immediately.
Skin:
In case of contact, immediately flush skin with plenty of water.
Remove contaminated clothing and shoes. Get medical aid. Wash
clothing before reuse.
Ingestion:
If swallowed, do not induce vomiting unless directed to do so by
medical personnel. Never give anything by mouth to an unconscious
person. Get medical aid.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical aid.
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.
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:
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container. Clean up spills immediately,
observing precautions in the Protective Equipment section. Provide
ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Avoid contact with eyes, skin, and clothing. Use
only with adequate ventilation. Avoid breathing vapor or mist.
Storage:
Keep container closed when not in use. Store in a cool, dry,
well-ventilated area away from incompatible substances.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use process enclosure, local exhaust ventilation, or other
engineering controls to control airborne levels below recommended
exposure limits. Facilities storing or utilizing this material should
be equipped with an eyewash facility and a safety shower.
Exposure Limits
CAS# 149-57-5:
Personal Protective Equipment
Eyes:
Wear chemical splash goggles.
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.
