**** SECTION 3 - HAZARDS IDENTIFICATION ****

EMERGENCY OVERVIEW
Causes burns.Corrosive.

Potential Health Effects
Eye:
Causes eye burns.
Skin:
Harmful if absorbed through the skin. Causes skin burns.
Ingestion:
May cause severe gastrointestinal tract irritation with nausea,
vomiting and possible burns. May be harmful if swallowed.
Inhalation:
May cause severe respiratory tract irritation and possible burns.
Vapors may cause dizziness or suffocation.
Chronic:
No information found.

**** 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:
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. Possible aspiration hazard. Get medical aid
immediately.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen. Do NOT use mouth-to-mouth
resuscitation.
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. Combustible liquid. Containers may explode when
heated.
Extinguishing Media:
Use water spray to cool fire-exposed containers. Do NOT get water
inside containers. 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. Remove all sources of ignition. Do
not get water inside containers.

**** SECTION 7 - HANDLING and STORAGE ****

Handling:
Wash thoroughly after handling. Use with adequate ventilation. Do
not get in eyes, on skin, or on clothing. Empty containers retain
product residue, (liquid and/or vapor), and can be dangerous. Keep
container tightly closed. Keep away from heat, sparks and flame.
Avoid ingestion and inhalation. Do not pressurize, cut, weld, braze,
solder, drill, grind, or expose empty containers to heat, sparks or
open flames.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances.

**** 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# 503-74-2:

exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
