**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Flammable. Harmful in contact with skin and if swallowed.Light
sensitive.Water-reactive.
Potential Health Effects
Eye:
When substance becomes wet or comes in contact with moisture of the
mucous membranes, it will cause irritation. May cause chemical
conjunctivitis and corneal damage.
Skin:
Contact with skin causes irritation and possible burns, especially
if the skin is wet or moist. May cause dermatitis. May cause cyanosis
of the extremities.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. May be harmful if swallowed. Ingestion of large amounts
may cause CNS depression.
Inhalation:
Aspiration may lead to pulmonary edema. May be harmful if inhaled.
Vapors may cause dizziness or suffocation. May cause burning
sensation in the chest.
Chronic:
No information found.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid
immediately.
Skin:
Get medical aid. Flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes. Wash clothing
before reuse. Remove contaminated clothing and shoes. If
water-reactive products are embedded in the skin, no water should be
applied. The embedded products should be covered with a light oil.
Ingestion:
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 not breathing, give artificial respiration. If
breathing is difficult, give oxygen.
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. Vapors may form an explosive mixture with air.
Vapors can travel to a source of ignition and flash back. Will burn
if involved in a fire. Water Reactive. Material will react with
water and may release a flammable and/or toxic gas. Use water spray
to keep fire-exposed containers cool. Containers may explode in the
heat of a fire. Flammable solid. May ignite or explode on contact
with steam or moist air.
Extinguishing Media:
Use dry sand or earth to smother fire. For small fires, use dry
chemical, carbon dioxide, water spray or alcohol-resistant foam. For
large fires, use water spray, fog, or alcohol-resistant foam. Do NOT
use water directly on fire. Use water spray to cool fire-exposed
containers. Water may be ineffective. DO NOT USE WATER! Do NOT use
straight streams of water. Contact professional fire-fighters
immediately.
**** 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 or absorb material, then place into a
suitable clean, dry, closed container for disposal. Remove all
sources of ignition. Use a spark-proof tool. Do not expose spill to
water. A vapor suppressing foam may be used to reduce vapors.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Do not allow water to get into the container
because of violent reaction. Ground and bond containers when
transferring material. Use spark-proof tools and explosion proof
equipment. Avoid contact with eyes, skin, and clothing. Empty
containers retain product residue, (liquid and/or vapor), and can be
dangerous. Keep away from heat, sparks and flame. Avoid ingestion
and inhalation. Store protected from light. Do not allow contact
with water. Do not pressurize, cut, weld, braze, solder, drill,
grind, or expose empty containers to heat, sparks or open flames.
Keep from contact with moist air and steam.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. Store in a cool, dry, well-ventilated area away from
incompatible substances. Keep away from water. Flammables-area. Keep
containers tightly closed. Store protected from light.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use explosion-proof ventilation equipment. Use process enclosure,
local exhaust ventilation, or other engineering controls to control
airborne levels. Use adequate general or local explosion-proof
ventilation to keep airborne levels to acceptable levels.
Exposure Limits
CAS# 887-76-3:
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 minimize
contact with skin.
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. 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.
