============= Composition/Information on Ingredients =============
Name:METHYL ACETYLENE
CAS:74-99-7
Fraction by Wt: 100.0%
===================== Hazards Identification =====================
Reports of Carcinogenicity:NTP:No IARC:No OSHA:No
Health Hazards Acute and Chronic:INHALATION: SHORT TERM EXPOSURE:
irritation, difficulty breathing, headache, drowsiness, symptoms of
drunkenness, dilated pupils LONG TERM EXPOSURE: convulsions SKIN
CONTACT: SHORT TERM EXPOSURE: irritation (possibly severe),
blisters LONG TERM EXPOSURE: no information is available EYE
CONTACT: SHORT TERM EXPOSURE: frostbite LONG TERM EXPOSURE: no
information is available INGESTION: SHORT TERM EXPOSURE: no
information on significant adverse effects LONG TERM EXPOSURE: no
information is available
Medical Cond Aggravated by Exposure:
======================= First Aid Measures =======================
First Aid: INHALATION: If adverse effects occur, remove to
uncontaminated area. Give artificial respiration if not breathing.
Get immediate medical attention. SKIN CONTACT: If frostbite or
freezing occur, immediately flush with plenty of lukewarm water
(105-115 F; 41-46 C). DO NOT USE HOT WATER. If warm water is not
available, gently wrap affected parts in blankets. Get immediate
medical attention. EYE CONTACT: Immediately flush eyes with plenty
of water for at least 15 minutes. Then get immediate medical
attention. INGESTION: If a large amount is swallowed, get medical
attention.
===================== Fire Fighting Measures =====================
Flash Point:flammable
Lower Limits:1.7%
Upper Limits:12.5%
Extinguishing Media:carbon dioxide, regular dry chemical Large fires:
Flood with fine water spray.
Fire Fighting Procedures:Move container from fire area if it can be
done without risk. Cool containers with water spray until well
after the fire is out. Stay away from the ends of tanks. For fires
in cargo or storage area: Cool containers with water from unmanned
hose holder or monitor nozzles until well after fire is out. If
this is impossible then take the following precautions: Keep
unnecessary people away, isolate hazard area and deny entry. Let
the fire burn. Withdraw immediately in case of rising sound from
venting safety device or any discoloration of tanks due to fire.
For tank, rail car or tank truck: Stop leak if possible without
personal risk. Let burn unless leak can be stopped immediately. For
smaller tanks or cylinders, extinguish and isolate from other
flammables. Evacuation radius: 800 meters (1/2 mile). Do not
attempt to extinguish fire unless flow of material can be stopped
first. Flood with fine water spray. Cool containers with water
spray until well after the fire i out. Apply water from a protected
location or from a safe distance. Avoid inhalation of material or
combustion by-products. Stay upwind and keep out of low areas.
Evacuate if fire gets out of control or containers are directly
exposed to fire. Evacuation radius: 500 meters (1/3 mile). Consider
downwind evacuation if material is leaking. Stop flow of gas.
Unusual Fire/Explosion Hazard:Severe fire hazard. Moderate explosion
hazard. Gas/air mixtures are explosive. The gas is heavier than
air. Vapors or gases may ignite at distant ignition sources and
flash back.
================== Accidental Release Measures ==================
Spill Release Procedures:Avoid heat, flames, sparks and other sources
of ignition. Do not touch spilled material. Stop leak if possible
without personal risk. Reduce vapors with water spray. Keep
unnecessary people away, isolate hazard area and deny entry. Remove
sources of ignition. Ventilate closed spaces before entering.
Neutralizing Agent:
====================== Handling and Storage ======================
Handling and Storage Precautions:Store and handle in accordance with
all current regulations and standards. Subject to storage
regulations: U.S. OSHA 29 CFR 1910.101. Keep separated from
incompatible substances.
Other Precautions:
============= Exposure Controls/Personal Protection =============
Respiratory Protection:The following respirators and maximum use
concentrations are drawn from NIOSH and/or OSHA. 1700 ppm Any
supplied-air respirator. Any self-contained breathing apparatus
with a full facepiece. Escape - Any air-purifying respirator with a
full facepiece and an organic vapor canister. Any appropriate
escape-type, self-contained breathing apparatus. For Unknown
Concentrations or Immediately Dangerous to Life or Health - Any
supplied-air respirator with full facepiece and operated in a
pressure-demand or other positive-pressure mode in combination with
a separate escape supply. Any self-contained breathing apparatus
with a full facepiece.
Ventilation:Provide local exhaust ventilation system. Ventilation
equipment should be explosion-resistant if explosive concentrations
of material are present. Ensure compliance with applicable exposure
limits.
Protective Gloves:Wear insulated gloves.
Eye Protection:Wear splash resistant safety goggles with a faceshield.
Provide an emergency eye wash fountain and quick drench shower in
the immediate work area.
Other Protective Equipment:For the gas: Protective clothing is not
required. For the liquid: Wear appropriate protective, cold
insulating clothing.
