**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Flammable. Very toxic by inhalation. Irritating to eyes, respiratory
system and skin. May cause sensitization by skin contact.
Potential Health Effects
Eye:
May cause eye irritation. May cause chemical conjunctivitis and
corneal damage.
Skin:
May cause skin irritation and possible burns. May cause
sensitization by skin contact.
Ingestion:
May cause digestive tract disturbances. The toxicological properties
of this substance have not been fully investigated. May cause nausea,
vomiting, abdominal pain, and increased salivation.
Inhalation:
May be fatal if inhaled. May cause respiratory tract irritation. The
toxicological properties of this substance have not been fully
investigated. May cause dyspnea (difficult or labored breathing).
Olfactory fatigue may occur. Can produce delayed pulmonary edema.
Chronic:
No information found.
**** 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.
Skin:
In case of contact, immediately flush skin with soap and plenty of
water. Remove contaminated clothing and shoes. Get medical aid if
symptoms occur. 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:
POISON material. If inhaled, get medical aid immediately. Remove
victim to fresh air. If not breathing, give artificial respiration.
If breathing is difficult, give oxygen.
Notes to Physician:
Treat symptomatically and supportively.
**** 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. Use water spray to keep fire-exposed containers
cool. Containers may explode in the heat of a fire. Flammable solid.
May burn rapidly with flare burning effect. May re-ignite after fire
is extinguished.
Extinguishing Media:
Water may be ineffective. For large fires, use water spray, fog or
regular foam. Contact professional fire-fighters immediately. For
small fires, use dry chemical, carbon dioxide, sand, earth, water
spray or regular foam. 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:
Sweep up or absorb material, then place into a suitable clean, dry,
closed container for disposal. Scoop up with a nonsparking tool,
then place into a suitable container for disposal. Remove all sources
of ignition. Use a spark-proof tool. A vapor suppressing foam may be
used to reduce vapors. Water spray may reduce vapor but may not
prevent ignition in closed spaces.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Ground and bond containers when
transferring material. Use spark-proof tools and explosion proof
equipment. Avoid contact with eyes, skin, and clothing. Do not
breathe dust, vapor, mist, or gas. Empty containers retain product
residue, (liquid and/or vapor), and can be dangerous. Keep container
tightly closed. Keep away from heat, sparks and flame. Do not
pressurize, cut, weld, braze, solder, drill, grind, or expose empty
containers to heat, sparks or open flames. Use only with adequate
ventilation.
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. Keep
refrigerated. (Store below 4C/39F.)
**** 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 general or
local explosion-proof ventilation to keep airborne levels to
acceptable levels.
Exposure Limits
CAS# 24424-99-5:
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:
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.
