Isobutane, volume 75-28-5 1000 ppm, OSHA 80%
PHYSICAL DATA
Boiling Point 15.5 鈥? 31.1掳F
Pressure in can at 70EF Approx. 30 psig
Vapor Density (Air=1) Greater than 2
Solubility in water Less than 0.1% by weight @70F
Specific Gravity (Water=1) 0.5669
Percent Volatile by weight 100%
Evaporation Rate (BuAce=1) Gas
Appearance and odor Liquefied compressed gas, flash evaporates at room temperature when
released from can, colorless gas with strong mercaptan (skunk-like)
odor due to stenching agent added to gas for leak detection purposes.
HAZARDOUS REACTIVITY
Stability Stable when stored as a liquid in cans under its own pressure.
Conditions to avoid Contact with sparks, open flame or any source of ignition.
Hazardous Polymerization Will not occur
Hazardous Decomposition
Products May produce carbon monoxide when oxidized with deficiency of oxygen.
FIRE AND EXPLOSION DATA
Flammability Category Extremely Flammable (Reference - Consumer Product Commission, flame projection
test for aerosol products, per 16 CFR 1500.45)
Flash Point Less than -117EF
Flammable Limits LEL% 1.8 UEL% 8.5
Extinguishing Media If feasible, stop flow of gas. Use water to cool fire-exposed cans, surroundings and
to protect personnel working on shut off. Water spray, dry powder or carbon dioxide
can be directed at flame area, if gas flow cannot be stopped, to reduce fire intensity.
DO NOT COMPLETELY EXTINGUISH FLAME UNLESS GAS FLOW IS SHUT
OFF!
Unusual Fire and
Explosion Hazards This product presents an extreme fire hazard. Liquid very quickly evaporates, even at
low temperatures, and forms vapor (fumes) which can catch fire and burn with
explosive violence. Invisible vapor spreads easily and can be set on fire by many
sources such as pilot lights, welding equipment, and electrical motors and switches.
For fires involving this material, do not enter any enclosed or confined fire space
without proper protective equipment. This may include self-contained breathing
Apparatus against the hazardous effects of normal products of combustion of oxygen
deficiency. Petroleum gases are heavier than air and travel along the ground or into
drains to possible distant ignition sources, causing an explosive flashback.
Special Fire Fighting
Procedures Avoid possible accumulations of vapors at floor level, as vapor is heavier than
air. Self-contained breathing apparatus and protective clothing should be worn
in fighting fires involving chemicals.
This product is extremely flammable at all times. Keep away from any sources
of inadvertent ignition, including heat, fire, sparks, or flame.

HEALTH HAZARD INFORMATION
Suggested Exposure Guideline 1000 ppm
Primary Route of Exposure Inhalation, skin contact, eye contact
Inhalation This product is an asphyxiate and may exhibit anesthetic properties at very high
concentrations. Initial symptoms of exposure at these concentrations are disorentation,
lack of coordination, rapid respiration, headache, and nausea. Continued exposure
May result in unconsciousness, coma, and possible death.
Skin Contact Vapors are not irritating. Freeze burns or frostbite possible if skin is in
prolonged contact with vaporizing liquid.
Eye Contact Same as skin contact.
Carcinogenicity None of the components in this material are listed by IARC, NTP, OSHA, or
ACGIH as a carcinogen.
FIRST AID
Inhalation Remove to fresh air. Artificial respiration, consult physician.
Skin Contact Wash with soap and water. Remove soaked clothing to avoid prolonged skin
contact.
Eye Contact Flush eyes well with running water for 15 minutes.
Ingestion NA, product is gaseous at normal temperature and pressure.
SPILL OR LEAK PROCEDURES
Steps to be taken in
case material is released
or spilled Protect from any ignition source, keep away from heat, fire, sparks, or flame.
Ventilate area well. Avoid accumulation of vapor at low levels.
Waste disposal method Dispose of in accordance with all local, state and federal
regulations. Do not puncture or incinerate.
SPECIAL PROTECTION INFORMATION
Respiration Protection If TLV is exceeded wear NIOSH-approved self-contained breathing
device or respirator.
Ventilation Must be adequate to maintaining airborne concentrations below established exposure
limits, particularly at floor level as vapors are heavier than air.
Protective gloves None needed for normal use. Thermal insulated gloves when handling
if prolonged exposure expected.
Eye Protection Safety glasses or goggles recommended
