OSHA Regulatory Status: This material is classified as hazardous under OSHA regulations.
Emergency Overview:
Simple Asphyxiant – This product does not contain oxygen and may cause asphyxia if released in a confined area. High
concentrations of butane may have central nervous system effect. Maintain oxygen levels above 19.5%. Contents under pressure.
Use and store below 125 OF (520C). Nonflammable when butane concentration is less than 5.6%, flammable if above 5.6% (CGA
Pamphlet P-23 2003).

Hazards Identification Continued
Carcinogenicity: NTP: No IARC: No OSHA: No
Eye Effects:
Contact with rapidly expanding gas near the point of release may cause frostbite.
Skin Effects:
Contact with rapidly expanding gas near the point of release may cause frostbite with redness, skin color change to gray or white, and
blistering.
Ingestion Effects:
None known. Ingestion is unlikely as product is a gas at room temperature.
Inhalation Effects:
Inhalation of butane vapors may cause dizziness, headache and nausea. High concentrations may depress the central nervous system,
causing a loss of consciousness and respiratory paralysis.
Product is a simple asphyxiant. High concentrations may exclude an adequate supply of oxygen to the lungs. Effects of oxygen
deficiency resulting from simple asphyxiants may include: rapid breathing, diminished mental alertness, impaired muscular
coordination, faulty judgment, 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.
Medical Conditions Aggravated by Exposure: None known.

Hazard ratings were assigned in accordance with Compressed Gas Association (CGA) guidelines as published in CGA Pamphlet P19-2004, CGA Recommended Hazard Ratings for Compressed Gases, 2nd Edition.
Eyes:
None required for gas. If frostbite is suspected, flush eyes with cool water for 15 minutes and obtain immediate medical attention.
Skin:
None required for gas. For frostbite, immerse skin in lukewarm water. DO NOT USE HOT WATER. Obtain medical attention.
Ingestion:
None required.
Inhalation:
PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF OVEREXPOSURE. RESCUE PERSONNEL
SHOULD BE EQUIPPED WITH SELF-CONTAINED BREATHING APPARATUS. Victims 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 and, if breathing has stopped, administer artificial resuscitation and supplemental oxygen.
Further treatment should be symptomatic and supportive.
