3. HAZARD IDENTIFICATION
EMERGENCY OVERVIEW: This product is an colorless, liquefied gas with a foul odor. This product poses a
serious fire hazard when accidentally released. The gas is heavier than air, and may spread long distances. Distant
ignition and flashback are possible. Flame or high temperature impinging on a localized area of the cylinder of this
product can cause the cylinder to explode without activating the cylinder鈥檚 relief devices. This gas mixture is an
asphyxiant and presents a significant health hazard by displacing the oxygen in the atmosphere. Contact with the
liquefied gas can cause frostbite. Emergency responders must wear proper personal protective and fire-retardant
equipment, and have adequate fire protection, during the situations to which they are responding.
SYMPTOMS OF OVER-EXPOSURE BY ROUTE OF EXPOSURE:

6-8% Oxygen: 8 minutes, may be fatal in 50-100% of cases; 6 minutes, may be fatal in 25 to 50% of cases;
4-5 minutes, recovery with treatment.
4-6% Oxygen: Coma in 40 seconds, followed by convulsion, breathing failure, death.
WARNING: Exposure to atmospheres containing 8-10% or less oxygen will bring about unconsciousness
without warning and so quickly that individuals cannot help or protect themselves.
Lack of sufficient oxygen may cause serious injury or death.
OTHER POTENTIAL HEALTH EFFECTS: Contact with liquefied gas or rapidly expanding gases (which are released
under high pressure) may cause frostbite. Symptoms of frostbite include change in skin color to white or grayish-yellow.
The pain after such contact can quickly subside.
HEALTH EFFECTS OR RISKS FROM EXPOSURE: An Explanation in Lay Terms. Over-exposure to n--Butane may
cause the following health effects:
ACUTE: The most significant hazard associated with this product is inhalation of oxygen-deficient atmospheres.
Symptoms of oxygen deficiency include respiratory difficulty, ringing in ears, headaches, shortness of breath, wheezing,
headache, dizziness, indigestion, nausea, and, at high concentrations, unconsciousness or death may occur. The skin of
a victim of over-exposure may have a blue color. Contact with liquid or rapidly expanding gases (which are released
under high pressure) may cause frostbite. Symptoms of frostbite include change in skin color to white or grayish-yellow.
The pain after contact with liquid can quickly subside.
CHRONIC: There are currently no known adverse health effects associated with chronic exposure to this compressed
gas.

PART II What should I do if a hazardous situation occurs?
4. FIRST-AID MEASURES
RESCUERS SHOULD NOT ATTEMPT TO RETRIEVE VICTIMS OF EXPOSURE TO THIS
PRODUCT WITHOUT ADEQUATE PERSONAL PROTECTIVE EQUIPMENT. At a minimum, Self-
Contained Breathing Apparatus and Fire-Retardant Personal Protective equipment should be
worn. Adequate fire protection must be provided during rescue situations.
Remove victim(s) to fresh air, as quickly as possible. Trained personnel should administer supplemental oxygen and/or
cardio-pulmonary resuscitation, if necessary. Only trained personnel should administer supplemental oxygen.
In case of frostbite, place the frostbitten part in warm water. DO NOT USE HOT WATER. If warm water is not
available, or is impractical to use, wrap the affected parts gently in blankets. Alternatively, if the fingers or hands are
frostbitten, place the affected area in the armpit. Encourage victim to gently exercise the affected part while being
warmed. Seek immediate medical attention.
Victim(s) must be taken for medical attention. Rescuers should be taken for medical attention, if necessary. Take copy
of label and MSDS to physician or other health professional with victim(s).

fire-exposed containers, structures, and equipment.
UNUSUAL FIRE AND EXPLOSION HAZARDS: When involved in a fire, this
material may decompose and produce toxic gases (including carbon monoxide
and carbon dioxide). OTHER
See Section 16 for
DANGER! Fires impinging (direct flame) on the outside surface of unprotected
Definition of Ratings
pressure storage vessels of this product can be very dangerous. Direct flame
exposure on the cylinder wall can cause an explosion either by BLEVE (Boiling
Liquid Expanding Vapor Explosion), or by exothermic decomposition. This is a catastrophic failure of the vessel releasing
the contents into a massive fireball and explosion. The resulting fire and explosion can result in severe equipment
damage and personnel injury or death over a large area around the vessel. For massive fires in large areas, use
unmanned hose holder or monitor nozzles; if this is not possible, withdraw from area and allow fire to burn.
Explosion Sensitivity to Mechanical Impact: Not sensitive.
Explosion Sensitivity to Static Discharge: Static discharge may cause this product to ignite explosively, if released.
SPECIAL FIRE-FIGHTING PROCEDURES: The best fire-fighting technique may be simply to let the burning gas escape
from the pressurized cylinder, tank car, or pipeline. Stop the leak before extinguishing fire. If the fire is extinguished
before the leak is sealed, the still-leaking gas could explosively re-ignite without warning and cause extensive damage,
injury, or fatality. In this case, increase ventilation (in enclosed areas) to prevent flammable or explosive mixture
formation. Structural fire-fighters must wear Self-Contained Breathing Apparatus and full protective equipment. Because
of the potential for a BLEVE, evacuation of non-emergency personnel is essential. If water is not available for cooling or
protection of vessel exposures, evacuate the area. Other information for pre-planning can be found in the American
Petroleum Institute Publications 2510 and 2510A , and the North American Emergency Response Guidebook (Guide
Number 116P).
6. ACCIDENTAL RELEASE MEASURES
SPILL AND LEAK RESPONSE: Uncontrolled releases should be responded to by trained personnel using pre-planned
procedures. Proper protective equipment should be used. In case of a spill, clear the affected area, protect people, and
respond with trained personnel. Adequate fire protection must be provided. Minimum Personal Protective Equipment
should be Level B: fire-retardant protective clothing, mechanically-resistant gloves and Self-Contained Breathing
Apparatus. Use only non-sparking tools and equipment. Locate and seal the source of the leaking gas. Protect
personnel attempting the shut-off with water-spray. Allow the gas to dissipate. Monitor the surrounding area for oxygen
and combustible gas levels.
MAPP GAS (Document # 002015) MSDS
PAGE 3 OF 9
6. ACCIDENTAL RELEASE MEASURES (Continued)
The atmosphere must have at least 19.5 percent oxygen before personnel can be allowed in the area without Self-
Contained Breathing Apparatus. Combustible gas concentration must be below 10% of the LEL prior to entry. Attempt
to close the main source valve prior to entering the area. If this does not stop the release (or if it is not possible to reach
the valve), allow the gas to release in-place or remove it to a safe area and allow the gas to be released there.
THIS IS AN EXTREMELY FLAMMABLE GAS. Protection of all personnel and the area must be maintained.
PART III How can I prevent hazardous situations from occurring?
7. HANDLING and STORAGE
WORK PRACTICES AND HYGIENE PRACTICES: As with all chemicals, avoid getting this product IN YOU. Do not
eat or drink while handling chemicals. Be aware of any signs of dizziness or fatigue; exposures to fatal concentrations of
this product (due to oxygen displacement) could occur without any significant warning symptoms.
STORAGE AND HANDLING PRACTICES: Cylinders should be stored in dry, well-ventilated areas away from sources
of heat. Compressed gases can present significant safety hazards. Store containers away from heavily trafficked areas
and emergency exits. Post 鈥淣o Smoking or Open Flames鈥? signs in storage or use areas.
SPECIAL PRECAUTIONS FOR HANDLING GAS CYLINDERS: Protect cylinders against physical damage. Store in
cool, dry, well-ventilated area, away from sources of heat, ignition and direct sunlight. Do not allow area where cylinders
are stored to exceed 52 掳C (125 掳F). Isolate from oxidizers such as oxygen, chlorine, or fluorine. Use a check valve or
trap in the discharge line to prevent hazardous backflow. Post 鈥淣o Smoking or Open Flame鈥? signs in storage and use
areas. Cylinders should be stored upright and be firmly secured to prevent falling or being knocked over. Cylinders can
be stored in the open, but in such cases, should be protected against extremes of weather and from the dampness of the
ground to prevent rusting. Never tamper with pressure relief devices in valves and cylinders. Electrical equipment should
be non-sparking or explosion proof. The following rules are applicable to situations in which cylinders are being used:
Before Use: Move cylinders with a suitable hand-truck. Do not drag, slide or roll cylinders. Do not drop cylinders or
permit them to strike each other. Secure cylinders firmly. Leave the valve protection cap, if provided, in-place until
cylinder is ready for use.
During Use: Use designated CGA fittings and other support equipment. Do not use adapters. Do not heat cylinder by
any means to increase the discharge rate of the product from the cylinder. Use check valve or trap in discharge line to
prevent hazardous backflow into the cylinder. Do not use oils or grease on gas-handling fittings or equipment.
After Use: Close main cylinder valve. Replace valve protection cap, if provided. Mark empty cylinders 鈥淓MPTY鈥?.
NOTE: Use only DOT or ASME code containers. Earth-ground and bond all lines and equipment associated with this
product. Close valve after each use and when empty. Cylinders must not be recharged except by or with the consent of
owner. For additional information refer to the Compressed Gas Association Pamphlet P-1, Safe Handling of
Compressed Gases in Containers. Additionally, refer to CGA Bulletin SB-2 鈥淥xygen Deficient Atmospheres鈥?.
PROTECTIVE PRACTICES DURING MAINTENANCE OF CONTAMINATED EQUIPMENT: Follow practices indicated
in Section 6 (Accidental Release Measures). Make certain application equipment is locked and tagged-out safely. Purge
gas handling equipment with inert gas (i.e. nitrogen) before attempting repairs. Always use product in areas where
adequate ventilation is provided.
8. EXPOSURE CONTROLS - PERSONAL PROTECTION
VENTILATION AND ENGINEERING CONTROLS: Use with adequate ventilation. Local exhaust ventilation is preferred,
because it prevents dispersion of this gas mixture into the work place by eliminating it at its source. If appropriate, install
automatic monitoring equipment to detect the level of oxygen and the presence of potentially explosive air-gas mixtures.
RESPIRATORY PROTECTION: Maintain oxygen levels above 19.5% in the workplace. Use supplied air respiratory
protection if oxygen levels are below 19.5% or during emergency response to a release of this product. If respiratory
protection is required, follow the requirements of the Federal OSHA Respiratory Protection Standard (29 CFR
1910.134), or equivalent State standards.
EYE PROTECTION: Splash goggles or safety glasses, for protection from rapidly expanding gases and splashes of
liquefied gas mixture.
HAND PROTECTION: Wear mechanically-resistant gloves when handling cylinders of this product.
BODY PROTECTION: Use body protection appropriate for task. Transfer of large quantities under pressure may
require protective equipment appropriate to protect employees from splashes of liquefied product, as well as fire
retardant items.

N-BUTANE:
LC50 (mouse, inhalation): 680g/m3; 2-hour duration of exposure
LC50 (rat, inhalation): 658 mg/L; 4 hour duration of exposure.
INHALATION (mouse): n-Butane is reported to be anesthetic to mice at 13% concentration in 25 minutes, at 22% in 1 minute.
INHALATION ( dog): n-Butane is reported to be anesthetic to dogs at 25% concentration. n-Butane is also a weak cardiac sensitizer (high
concentrations can cause abnormal heartbeats in animals under stress).
ISOBUTANE: There is no specific toxicology data for Isobutane. Isobutane is a simple asphyxiant.
PROPANE. Skin Contact (Rabbit): Several formulations containing an isobutane-propane mixture have been tested for skin irritation effects. All
formulations contained less than 13% propane. All of the formulations containing propane caused only mild irritation.
Effects on Short-Term Inhalation: Guinea-pigs breathing 5.5% propane by volume developed tremors after 5 minutes. Nausea, retching, and
stupefaction were observed when animals were exposed for 30-120 minutes. All the animals survived a two-hour exposure and had no
significant tissue damage. A gas concentration of 89% did not cause anesthesia, but depressed the blood pressure of cats. Inhalation of 10
percent propane by mice and 15% by dogs caused weak cardiac sensitization, Presumably, all of these effects are reversible when exposure
ceases. In primates, 10% propane caused some change in heart function. At 20% there was aggravation of these symptoms and respiratory
depression.
Effects of Long-Term Inhalation: No toxicity or abnormalities were observed when monkeys were exposed to approximately 750 ppm for 90 days.
Similar results were obtained when monkeys were exposed to an aerosol spray containing 65% propane and isobutane.
MAPP GAS (Document # 002015) MSDS
PAGE 5 OF 9
11. TOXICOLOGICAL INFORMATION (Continued)
TOXICITY DATA (continued):
PROPYLENE: Effects on Short-Term Inhalation: In all species tested, propylene is an anesthetic, being approximately twice as toxic as
ethylene. A concentration of 40% produced light anesthesia in rats, with no toxic effects within 6 hours of exposure. Exposure to 55% for 3 to 6
minutes, 65% for 2 to 5 minutes, and 70% for 1 to 3 minutes caused deep anesthesia with no central nervous system disturbances. In cats, no
toxic signs were observed when anesthesia was induced with propylene concentrations of 20-30%. However, at higher concentrations, toxic
effects were seen. Some subtle effects were seen from 40-50%;, a drop in blood pressure and increased pulse rate at 70%; and an unusual
heart beat from 50-80%. Propylene has been found to be a cardiac sensitizer in dogs. After 4 hours of inhalation exposure to 50,000 ppm
propylene, rats pretreated with Aroclor 1254 (a hepatic mixed-function, oxidase inducer) showed liver toxicity. No liver toxicity was observed in
control rats or rats pretreated with phenolbarbital or beta-naphthoflavone. This evidence suggests that Aroclor pre-treatment is a prerequisite for
propylene liver toxicity.
Effects of Long-Term Inhalation: Chronic exposure to mice to concentrations causing central nervous system depression resulted in moderate to
very slight fatty degeneration of the liver.
SUSPECTED CANCER AGENT: Specific components of this gas mixture are listed, as follows:
1,3-BUTADIENE:
EPA- B2, Probable Human Carcinogen (sufficient evidence from animal studies; inadequate evidence in epidemiological studies)
IARC - Group 2A; Probably Carcinogenic to Humans (limited human evidence; sufficient evidence in experimental animals)
MAK-A2; Unmistakably Carcinogenic in Animal Experimentation Only
NTP- Group 2, Reasonably Anticipated to be a Carcinogen
ACGIH - A2; Suspect Human Carcinogen
PROPYLENE:
IARC-3: Not Classifiable as to Carcinogenicity to Humans)
ACGIH-A4 : Not Classifiable as Human Carcinogen
The other components of this mixture are not found on the following lists: FEDERAL OSHA Z LIST, NTP, IARC,
CAL/OSHA, and therefore are not considered to be, nor suspected to be cancer-causing agents by these agencies.
IRRITANCY OF PRODUCT: This product is not irritating; however, contact with the liquefied gas mixture or rapidly
expanding gases can cause frostbite to exposed tissue.
SENSITIZATION TO THE PRODUCT: This gas mixture is not known to cause sensitization in humans; however, some
animals studies indicate that exposure to n-Butane, Propylene, and Propane (components of this gas mixture) can cause
weak cardiac sensitization.
REPRODUCTIVE TOXICITY INFORMATION: Listed below is information concerning the effects of this product and its
components on the human reproductive system.
Mutagenicity: No mutagenicity effects have been described for this has mixture. 1,3-Butadiene (a component of this
product) and its metabolites have exhibited mutagenicity in bacterial tests.
Embryotoxcity: No embryotoxic effects have been described for this gas mixture. Refer to the following paragraph for
additional information.
Teratogenicity: No teratogenicity effects have been described for this gas mixture. Pregnant rats were exposed to 200,
1000, or 8000 ppm 1,3-Butadiene (a component of this gas mixture) on days 6-15 of gestation. Dose-related
maternal and fetal toxicity were observed. Offspring of rats exposed at 8000 ppm had increased numbers of major
skeletal abnormalities.
Reproductive Toxicity: No reproductive toxicity effects have been described for this gas mixture. No reproductive effects
nor other significant toxic effects were observed in two inhalation studies using rats (1000-8000 ppm; 6 hours/day for
5 days/week over 13 weeks) or rats and guinea pigs (600-6700 ppm daily for 3 months) exposed to 1,3-Butadiene (a
component of this gas mixture). In the long-term carcinogenicity studies, there were increased frequencies of uterine
and testicular cancers in mice. Non-cancerous atrophy of the ovaries and testes also occurred in mice.
A mutagen is a chemical which causes permanent changes to genetic material (DNA) such that the changes will
propagate through generation lines. An embryotoxin is a chemical which causes damage to a developing embryo (i.e.
within the first eight weeks of pregnancy in humans), but the damage does not propagate across generational lines. A
teratogen is a chemical which causes damage to a developing fetus, but the damage does not propagate across
generational lines. A reproductive toxin is any substance which interferes in any way with the reproductive process.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: Acute or chronic respiratory conditions may be aggravated
by over-exposure to the components of this product.
