SECTION 5: Fire-fighting measures
5.1 Suitable extinguishing media
Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide.
5.2 Specific hazards arising from the chemical
Excerpt from ERG Guide 115 [Gases - Flammable (Including Refrigerated Liquids)]: EXTREMELY FLAMMABLE. Will be easily ignited by heat, sparks or flames. Will form explosive mixtures with air. Vapors from liquefied gas are initially heavier than air and spread along ground. CAUTION: Hydrogen (UN1049), Deuterium (UN1957), Hydrogen, refrigerated liquid (UN1966) and Methane (UN1971) are lighter than air and will rise. Hydrogen and Deuterium fires are difficult to detect since they burn with an invisible flame. Use an alternate method of detection (thermal camera, broom handle, etc.) Vapors may travel to source of ignition and flash back. Cylinders exposed to fire may vent and release flammable gas through pressure relief devices. Containers may explode when heated. Ruptured cylinders may rocket. (ERG, 2016)
5.3 Special protective actions for fire-fighters
Shut off supply; if not possible and no risk to surroundings, let the fire burn itself out. In other cases extinguish with powder, carbon dioxide. In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position.
SECTION 6: Accidental release measures
6.1 Personal precautions, protective equipment and emergency procedures
Evacuate danger area! Consult an expert! Personal protection: self-contained breathing apparatus. Ventilation. Remove all ignition sources. NEVER direct water jet on liquid.
6.2 Environmental precautions
Evacuate danger area! Consult an expert! Personal protection: self-contained breathing apparatus. Ventilation. Remove all ignition sources. NEVER direct water jet on liquid.
6.3 Methods and materials for containment and cleaning up
Evacuate danger area! Consult an expert! Personal protection: self-contained breathing apparatus. Ventilation. Remove all ignition sources. NEVER direct water jet on liquid.
SECTION 7: Handling and storage
7.1 Precautions for safe handling
NO open flames, NO sparks and NO smoking. Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding) if in liquid state. Use non-sparking handtools. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
7.2 Conditions for safe storage, including any incompatibilities
Fireproof. Cool.Butane in liquid form may be stored both above and below ground. Besides storage in liquefied form under its vapor pressure at normal atmospheric temperatures, refrigerated liquid storage at atmospheric pressure may be used. Such systems are closed and insulated, and the liquid petroleum gas vapor is circulated through pumps and compressors to serve as the refrigerant for the system. Butane may be stored in pits in the earth capped by metal domes and in underground chambers.

SECTION 9: Physical and chemical properties and safety characteristics
| Physical state | Butane is a colorless gas with a faint petroleum-like odor. For transportation it may be stenched. It is shipped as a liquefied gas under its vapor pressure. Contact with the liquid can cause frostbite. It is easily ignited. Its vapors are heavier than air. Any leak can be either liquid or vapor. Under prolonged exposure to fire or intense heat the containers may rupture violently and rocket. It is used as a fuel, an aerosol propellant, in cigarette lighters, and to make other chemicals. |

The gas is heavier than air and may accumulate in lowered spaces causing a deficiency of oxygen. As a result of flow, agitation, etc., electrostatic charges can be generated.BUTANE can explode when exposed to flame or when mixed with (nickel carbonyl + oxygen). It can also react with oxidizers. Strong acids and alkalis should be avoided. (NTP, 1992).

12.2 Persistence and degradability
AEROBIC: A mean half-life of 5.9 days was reported for all detectable hydrocarbons in an aerobic biodegradation study of gasoline in water from a domestic sewage treatment plant(1). Among the last compounds to be degraded was butane, for which a degradation half-life was calculated as 15 days(1). Within 24 hrs, n-butane was oxidized to its corresponding methyl ketone, 2-butanone(2,3), and the corresponding alcohol, 2-butanol(3,4), by cell suspensions of over 20 methyltrophic organisms isolated from lake water and soil samples(1-3). After 192 hrs, the concentration of n-butane contained in gasoline was reduced from 0.63 to 0.37 uL/L for both a sterile control and a mixed culture sample collected from ground water contaminated with gasoline; these data indicate that n-butane was not biodegraded over the study period(5). The biodegradation of n-butane in a Columbia River soil was measured over 50 days; a degradation rate of 1.8 mgC/day/kg dry soil was reported without the addition of nitrogen(6). When nitrogen at 0.15 mg per bottle was added, the degradation rate increased to 11.4 mg C/day/kg dry soil(6). 100% of the initially added n-butane (32.9 mg/L) was biodegraded over 34 days in a screening study using an activated sludge inoculum(7).
12.3 Bioaccumulative potential
An estimated BCF of 33 was calculated for n-butane(SRC), using a log Kow of 2.89(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate(SRC).
12.4 Mobility in soil
The Koc of n-butane is estimated as 900(SRC), using a measured log Kow of 2.89(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that n-butane is expected to have low mobility in soil.
12.5 Other adverse effects
no data available
SECTION 13: Disposal considerations
13.1 Disposal methods
Product
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Contaminated packaging
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.

Other Information
Check oxygen content before entering area.Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.Information except physical properties also apply for Isobutane (CAS 75-28-5).High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death.
