EYE EFFECTS: Contact with liquid may cause frostbite, irritation or blindness.

SKIN EFFECTS: Contact with liquid will cause frostbite or irritation.

INGESTION EFFECTS: Ingestion is unlikely. The effects of ingestion are unknown. However minimal
health effects are anticipated. Consult a physician for treatment or contact the local poison control center.

INHALATION EFFECTS: High concentrations may cause central nervous system depression or act as an
asphyxiant. Anesthetic effects may include dizziness, sleepiness, and incoordination. Effects of oxygen
deficiency resulting from simple asphyxiants may include: rapid breathing, diminished mental alertness,
impaired muscular coordination, faulty judgement, depression of all sensations, emotional instability, and
fatigue. As asphyxiation progresses, nausea, vomiting, prostration, and loss of consciousness may result,
eventually leading to convulsions, coma, and death.

MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: Irritant properties may aggravate pre-
existing eye and skin disorders.

POTENTIAL ENVIRONMENTAL EFFECTS: Ecotoxicity values were unavailable. Toxic effects are
expected to be similar to those seen in humans and test animals.

4. First Aid Measures

EYES: Never introduce ointment or oil into the eyes without medical advice! In case of freezing caused by
rapidly evaporating liquid, DO NOT WASH THE EYES WITH HOT OR EVEN TEPID WATER! Remove
victim from the source of contamination. For contact with small amounts of liquid, open the eyelids wide to
allow the liquid to evaporate. For contact with large amounts, rinse with a low pressure stream of cool water for
15 minutes. Refer the victim to an ophthalmologist for treatment and follow up. If the victim cannot tolerate
light, protect the eyes with dark glasses. The use of bandages is not recommended as keeping the eyelids closed
or exerting pressure on the eyelid may cause further damage.

SKIN: For dermal contact or frostbite: Remove contaminated clothing and flush affected areas with lukewarm
water. DO NOT USE HOT WATER. A physician should see the patient promptly if contact with the product
has resulted in frostbite.

INGESTION: Keep victim calm and warm. Notify physician and inform of nature of material, the state of the
victim and any observed signs or symptoms.

INHALATION: PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF
OVEREXPOSURE. RESCUE PERSONNEL SHOULD BE EQUIPPED WITH SELF-CONTAINE BREATHING APPARATUS.

Conscious persons should be assisted to an uncontaminated area and inhale fresh air. Quick removal from the
contaminated area is most important. If breathing is difficult, administer oxygen. Unconscious persons should
be moved to an uncontaminated area, given mouth-to-mouth resuscitation and supplemental oxygen. Further
treatment should be symptomatic and supportive.

Closed Cup
LEL(%): 3.0 UEL(%): 11.0

Sensitivity to static discharge: None

FIRE AND EXPLOSION HAZARDS:
Highly flammable gas mixture. This gas is heavier than air and may travel a considerable distance to an ignition
source. May burn with an almost invisible flame in bright light. Cylinder may vent rapidly or rupture violently
from pressure when involved in a fire situation.

EXTINGUISHING MEDIA:
Water fog, dry chemical, foam.

FIRE FIGHTING INSTRUCTIONS:
If possible, stop the flow of gas. Inerting the atmosphere to reduce oxygen levels may extinguish flame,
allowing capping of leaking container. Do not attempt this unless specifically trained. Reduce the rate of flow
and inject an inert gas, if possible, before completely stopping the flow to prevent flashback. Do not extinguish
the fire until the supply is shut off as otherwise an explosive re-ignition may occur. If the fire is extinguished
and the flow of gas continues, use increased ventilation to prevent build-up of explosive atmosphere. Use non-
sparking tools to close container valves.

Use water spray to cool surrounding containers. Be cautious of a Boiling Liquid Evaporating Vapor Explosion,
BLEVE, if flame is impinging on surrounding containers. Direct 500 GPM water stream onto containers above
liquid level with remote monitors. Limit the number of personnel in proximity of fire and evacuate surrounding
areas in all directions.

Firefighters should wear respiratory protection (SCBA) and full turnout or Bunker gear. Continue to cool fire-
exposed cylinders until well after flames are extinguished.

6. Accidental Release Measures

WARNING: Any leaks of MAPP present great danger of explosion or fire. Keep all sources of ignition well
away from leak. Extinguish any existing ignition sources and evacuate all personnel from affected area. Use
appropriate protective equipment (See Section 8). If leak is in user's equipment, be certain to purge piping with
inert gas prior to attempting repairs. If leak is in container or container valve, contact the appropriate emergency
telephone number listed in Section 1 or call your closest BOC location.

7. Handling and Storage
Electrical Classification: Class I, Group Not Specified.

Earth bond and ground all lines and equipment associated with the fuel gas system. All equipment should be
non-sparking and explosion proof.

Use only in well-ventilated areas. Valve protection caps must remain in place unless container is secured with
valve outlet piped to use point. Do not drag, slide or roll cylinders. Use a suitable hand truck for cylinder
movement. Use a pressure regulator when connecting cylinder to lower pressure piping or systems. Do not heat
cylinder by any means to increase the discharge rate of product from the cylinder. Use a check valve or trap in
the discharge line to prevent hazardous back flow into the cylinder. Do not insert any object (i.e.: screwdriver)
into valve cap openings as this can damage the valve causing leakage.

Protect cylinders from physical damage. Store in cool, dry, well-ventilated area away from heavily trafficked
areas and emergency exits. Do not allow the temperature where cylinders are stored to exceed 125oF (52oC).
Cylinders should be stored upright and firmly secured to prevent falling or being knocked over. Full and empty
cylinders should be segregated. Use a "first in-first out" inventory system to prevent full cylinders from being
stored for excessive periods of time. Post "NO SMOKING OR OPEN FLAMES" signs in the storage or use
area. There should be no sources of ignition in the storage or use area. This fuel gas should not be handled or
used in metals that form acetylides, such as copper, silver, magnesium or their alloys.

For additional recommendations consult Compressed Gas Association Pamphlet P-1.

Never carry a compressed gas cylinder or a container of a gas in cryogenic liquid form in an enclosed space such
as a car trunk, van or station wagon. A leak can result in a fire, explosion, asphyxiation or a toxic exposure.

8. Exposure Controls, Personal Protection

ENGINEERING CONTROLS: Use enclosures and local exhaust ventilation as necessary to limit exposure
below the acceptable exposure limits. Exhaust gas should be vented to a gas treatment system. If product is
handled routinely where the potential for leaks exists, all electrical equipment must be rated for use in potentially
flammable atmospheres. Consult the National Electrical Code for details.

EYE/FACE PROTECTION: Safety glasses with filter lenses, shade #4 or darker.

SKIN PROTECTION: Leather gloves and apron when welding, cutting or brazing.

RESPIRATORY PROTECTION: For emergency release use a positive pressure NIOSH approved air-
supplying respirator systems (SCBA or airline/escape bottle) using at a minimum Grade D air.
