EMERGENCY OVERVIEW
This product does not contain oxygen and may cause asphyxia if released in a confined area. Simple
hydrocarbons can cause irritation and central nervous system depression at high concentrations.
Extremely flammable.

Carcinogenicity: -- NTP: No IARC: No OSHA: No
EYE EFFECTS:
Irritation may occur.
SKIN EFFECTS:
No adverse effects anticipated as product is a gas at room temperature.
INGESTION EFFECTS:
Ingestion is unlikely.
INHALATION EFFECTS:
Product is relatively nontoxic. Simple hydrocarbons can irritate the eyes, mucous membranes and respiratory
system at high concentrations.
Inhalation of high concentrations may cause dizziness, disorientation, incoordination, narcosis, nausea or
narcotic effects.
This product may displace oxygen if released in a confined space. Maintain oxygen levels above 19.5% at sea
level to prevent asphyxiation.
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.
Oxygen deficiency during pregnancy has produced developmental abnormalities in humans and experimental
animals.

4. First Aid Measures
EYES:
Never introduce oil or ointment into the eyes without medical advice! If pain is present, refer the victim to an
ophthalmologist for further treatment and follow up.
SKIN:
Remove contaminated clothing and flush affected area with cold water and soap. DO NOT USE HOT WATER.
INGESTION:
Not normally required. Seek immediate medical attention.
INHALATION:
PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF OVEREXPOSURE TO
PRODUCT. RESCUE PERSONNEL SHOULD BE EQUIPPED WITH SELF-CONTAINED BREATHING
APPARATUS. Conscious persons should be assisted to an uncontaminated area and inhale fresh air. Quick
removal from the contaminated area is most important. Unconscious persons should be moved to an
uncontaminated area, given assisted (artificial) respiration and supplemental oxygen. Further treatment should
be symptomatic and supportive.
5. Fire Fighting Measures
Conditions of Flammability: Flammable gas
Flash point: Method: Autoignition
Not Available Not Applicable Temperature: Not Available
LEL(%): 2.4 UEL(%): 10.4
Hazardous combustion products: Carbon monoxide, Carbon dioxide
Sensitivity to mechanical shock: None
Sensitivity to static discharge: Not Available
FIRE AND EXPLOSION HAZARDS:
Cyclopropane is heavier than air and may travel a considerable distance to an ignition source. Cyclopropane is a
flammable gas! Keep away from open flame and other sources of ignition. Do not allow smoking in storage
areas or when handling.
EXTINGUISHING MEDIA:
Water, carbon dioxide, dry chemical.
FIRE FIGHTING INSTRUCTIONS:
If possible, stop the flow of gas with a remote valve. Use water spray to cool fire exposed containers. If fire is
extinguished and flow of gas is continued, increase ventilation to prevent a build up of a flammable/explosive
atmosphere. Extinguish sources of ignition.
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 the liquid level with remote monitors. Limit
the number of personnel in proximity to the fire. Evacuate surrounding areas to at least 3000 feet in all
directions.
6. Accidental Release Measures
MSDS: G-24
Revised: 6/7/96 Page 3 of 7
PRODUCT NAME: CYCLOPROPANE
Evacuate all personnel from affected area. Use appropriate protective equipment. Increase ventilation to
prevent build up of a flammable/explosive atmosphere. Extinguish all sources of ignition! If leak is in user鈥檚
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
Earth bond and ground all lines and equipment associated with the product system. Electrical equipment should
be non-sparking and explosion proof.
Cyclopropane is noncorrosive and may be used with common structural materials.
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 (<250 psig) 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.
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 130oF (54oC).
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" signs in storage or use areas.
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.

ENGINEERING CONTROLS:
Use local exhaust to prevent accumulation. Use general ventilation to prevent build up of flammable
concentrations. May use hood with forced ventilation when handling small quantities. 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.
