If irritation, pain, swelling, lacrimation, or photophobia persist, get medical attention as soon as possible.;Skin: Frostbite - Compressed gases may create low temperatures when they expand rapidly. Leaks and uses that allow rapid expansion may cause a frostbite hazard. Wear appropriate personal protective clothing to prevent the skin from becoming frozen.;Breathing: Respiratory support
Firefighting Hazards
Behavior in fire: Containers may explode; vapor is heavier than air & may travel a long distance to a source of ignition & flash back.
The gas is heavier than air and may travel along the ground; distant ignition possible, and may accumulate in low ceiling spaces causing deficiency of oxygen. As a result of flow, agitation, etc, electrostatic charges can be generated ... On loss of containment this liquid evaporates very quickly displacing the air and causing a serious risk of suffocation when in confined areas.
Exposure Control and Personal Protection
· Wear positive pressure self-contained breathing apparatus (SCBA).;· Structural firefighters' protective clothing provides thermal protection but only limited chemical protection.;· Always wear thermal protective clothing when handling refrigerated/cryogenic liquids.

1000.0 [ppm]
Fire Fighting Procedures
Stop flow of gas. For small fires use dry chemicals. Cool adjacent areas with water spray.
If material on fire or involved in fire: Do not extinguish fire unless flow can be stopped. Use water in flooding quantities as fog. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible.
Evacuation: If fire becomes uncontrollable or container is exposed to direct flame consider evacuation of one half mile radius.
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 ...
Storage Conditions
COMPRESSED GASES MAY BE STORED IN THE OPEN ONLY IF THEY ARE ADEQUATELY PROTECTED FROM THE WEATHER & DIRECT SUNLIGHT. STORAGE AREAS SHOULD BE LOCATED AT A SAFE DISTANCE FROM OCCUPIED PREMISES & NEIGHBORING DWELLINGS. /GASES & AIR, COMPRESSED/
Storage temp: ambient; venting: safety relief
Store cylinder outdoors without direct sunlight or heat radiation and with adequate ventilation. Provide electrical equipment with spark resistant construction.
Four main types of storage are used: high pressure storage aboveground, low pressure refrigerated storage aboveground, frozen earth storage, and underground cavern storage. 1) Aboveground pressure storage tanks are usually designed for a 1720 kPa (250 psi) working pressure ... 2) Refrigerated, aboveground storage tanks usually are designed for a few kPa (psi) of pressure. They must be coupled with refrigeration systems to cool the product ... to a temp equal to the product's boiling point @ the operating pressure of the tanks. Vapors are generally recondensed by refrigeration and returned to the tanks. 3) In frozen earth storage of propane, the walls and bottom of a pit in the ground are frozen and a dome is constructed over the pit. The pressure in the storage cavern is maintained @ nearly atmospheric pressure by refrigeration systems that cool the product to its boiling point @ storage pressure. Heat leaks into the cavity and vaporizes some of the propane; the vapor that is formed is compressed, cooled, and returned to the pit as liquid by the refrigeration system. ... 4) Underground storage caverns, which operate @ approx formation temp and @ the corresponding /liquified petrolem gas (LPG)/ vapor pressure ... must be of sufficient depth to develop an overburden pressure greater than the vapor pressure of the stored liquid. Mined storage caverns are about 60-152 m deep, whereas salt formation caverns may be from 106-1524 m deep ...
Fireproof. Cool.
Cleanup Methods
Evacuate danger area! Consult an expert! Remove all ignition sources. Ventilation. NEVER direct water jet on liquid. (Extra personal protection: self-contained breathing apparatus.) ... Check oxygen content before entering area. Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
1) Remove all ignition sources. 2) Ventilate area of leak. 3) Stop flow of gas. If source of leak is a cylinder & the leak cannot be stopped in place, remove the leaking cylinder to a safe place in the open air, & repair the leak or allow the cylinder to empty.
Nonfire Spill Response

CAUTION: When in contact with refrigerated/cryogenic liquids, many materials become brittle and are likely to break without warning. (ERG, 2024)
Disposal Methods
SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.
Propane may be disposed of by burning at a safe location or in a suitable combustion chamber.
毒性情報
Interactions
Propane, when used as an aerosol propellant with isobutane in deodorant and antiperspirant products (65 to 70% by wt), has not been shown to cause skin irritation in 125 human volunteers who applied the aerosol products twice daily for 12 wk.
When dogs were exposed to 15-90% propane concn for 10 min, the heart was more sensitive to ventricular fibrillations induced by epinephrine than without propane treament.
Environmental Fate
TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 460(SRC), determined from a log Kow of 2.36(2) and a regression-derived equation(3), indicates that propane is expected to have moderate mobility in soil(SRC). Volatilization of propane from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 7.07X10-1 atm-cu m/mole(SRC), derived from its vapor pressure, 7150 mm Hg(4), and water solubility, 62.4 mg/L(5). Propane is expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(4). Using cell suspensions of microogranisms isolated from soil and water, propane was oxidized to acetone within 24 hours(6,7), suggesting that biodegradation may be an important fate process in soil and sediment.
AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 460(SRC), determined from a log Kow of 2.36(2) and a regression-derived equation(3), indicates that propane is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 7.07X10-1 atm-cu m/mole(SRC) derived from its vapor pressure, 7150 mm Hg(4), and water solubility, 62.4 mg/L(5). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 41 minutes and 2.6 days, respectively(SRC). According to a classification scheme(6), an estimated BCF of 13.1(SRC), from its log Kow(2) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC). After 192 hr, the trace concn of propane contained in gasoline remained unchanged for both a sterile control and a mixed culture sample collected from ground water contaminated with gasoline(8). This indicates that biodegradation may not be an important fate process in water.
ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), propane, which has a vapor pressure of 7150 mm Hg at 25 °C(2), is expected to exist solely as a gas in the ambient atmosphere. Gas-phase propane is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 14 days(SRC), calculated from its rate constant of 1.15X10-12 cu cm/molecule-sec at 25 °C(3). Propane does not contain chromophores that absorb at wavelengths >290 nm and therefore is not expected to be susceptible to direct photolysis by sunlight(4).

Effluent Concentrations
In gasoline: 0.07-0.08 vol %; in flue gas of municipal incinerator: < 0.4-0.5 ppm
Flue gases from a waste incinerator at Babylon, Long Island, NY was found to emit propane at concn generally less than 0.5 ppm(1). Propane is a product of gasoline(2-5), natural gas(5) and polyethylene(6) combustion. The average exhaust from 67 gasoline fueled vehicles was found to contain propane at a concn 0.1% by weight(3). The average concn of propane for the exhaust of 46 automobiles was 2.6, 1.6 and 2.2 weight % of total hydrocarbon according to the federal test procedure, hot soak test and the New York City cycle, respectively(4). Propane from car exhaust ranged in concn from 0.02 to 0.05 ppmV with an average for 8 samples of 0.03 ppmV(5). A Texaco refinery located in Tulsa, OK was attributed with emissions to the surrounding atmosphere where the propane concn was measured to be 95.5 and 189.8 ppbC for two min before and after 1:33 PM(6). The propane content of the air downwind of a Mobil natural gas facility in Rio Blanco, CO was 465.3 ppbC(7). Underwater hydrocarbon vent discharges from offshore oil production platforms contained propane at a concentration in the vapor phase at 2,000 umol/L of gas(8).
Gas-phase propane was detected in a Los Angeles tunnel at a concentration of 47 mg/L(1). Propane was detected in a tunnel at a concentration of 26 ug/cu m(2) which was about 4 times greater than the background propane levels of 5.8 ug/cu m(2). Propane was found in the Cassiar tunnel in Vancouver, BC, Canada in 1993 and 1995 at mass fractions of 0.81 and 0.047, respectively, as well as Tuscorora, Caldecott and Fort McHenry tunnels at mass fractions of 0.08, 0.07 and 0.03, respectively(3). Propane accounted for 0.88, 0.95 and 1.17% of the emissions on a Raleigh, NC highway, Dyanomenter, and an Atlanta, GA roadway, respectively(4). Gasoline containing propane (100 ug/g) emitted propane from the tail pipes of catalytic and non catalytic engines at rates of 650 and 9,300 ug/km(5). Propane emissions from cars driving in urban, suburban, rural and motorways were observed as 7.8, 3.69, 2.13 and 1.35 mg/km(6). Propane concentration in exhaust had mean concentration of 0.21 ppm(7). Propane was detected with annual means of 1 ug/cu m in London, England background and curbside and annual mean ranging from 4-21 ug/cu m in European cities(7). Propane was detected in gasoline vapors at concentrations ranging from 0.02-2.8 mg/ cu m(8).

Metabolism/Metabolites
/Propane/ is metabolized by microorganism via the malonyl succinate pathway.
In mice ... /propane/ was converted to isopropanol and acetone following inhalation. In the presence of microsomes prepared from liver homogenate of mice, the test substance was converted in vitro to isopropanol, too. The oxidation of isopropanol to acetone occurred in the presence of alcohol dehydrogenase. The metabolites were detected in blood, liver, kidney and brain of the exposed mice.
Absorption, Distribution and Excretion
A death involving asphyxiation by propane inhalation is reported. The presence of propane was determined in blood, brain, kidney, liver, and lung by gas chromatography. The brain showed the highest level of propane, whereas the kidney exhibited the lowest level.
In mice exposed to a liquid gas mixture containing propane, butane, & isobutane, (at 17, 31, & 52%, respectively), death occurred within 15 seconds of exposure. Concn of the cmpd in lung tissue were max within 1 hr of death & decreased thereafter depending on the degree of putrefaction. No residues or only traces were detected by the 15th day postmortem. Max concn were observed in the adipose tissue 4 days after death & the cmpd were still detectable by the 15th day. /Propane, butane & isobutane mixture/
Inhalation represents the major route by which propane is absorbed systemically. Studies ... in human volunteers showed that blood levels of propane could be detected after exposure to 250-1,000 ppm. ... Compared to respiratory absorption, dermal penetration of propane can be considered to be very low. ... the distribution /in tissues/ can be expected to follow the same pattern observed for butane.

Methods of Manufacturing
Removed from lower boiling hydrocarbons & permanent gases in petroleum refining & natural gas processing
Constituent of natural gas and of crude petroleum. Obtained by the so called "stabilization process" using fractional distillation under pressure.
Propane is obtained from natural gas by fractionation following absorption in oil, adsorption to surface-active agents, or refrigeration.
A unique feature of propane is that it is not produced for its own sake, but is a by-product of two other processes, natural gas processing and petroleum refining... Natural gas plant production of propane primarily involves extracting materials such as propane and butane from natural gas to prevent these liquids from condensing and causing operational problems in natural gas pipelines. Similarly, when oil refineries make major products such as motor gasoline and heating oil, some propane is produced as a by-product of those processes. It is important to understand that the by-product nature of propane production means that the volume made available from natural gas processing and oil refining cannot be adjusted when prices and/or demand for propane fluctuate.

Propane: ACTIVE
Propane naturally occurs as a gas at atmospheric pressure but can be liquefied if subjected to moderately increased pressure. It is stored and transported in its compressed liquid form, but by opening a valve to release propane from a pressurized storage container, it is vaporized into a gas for use.
Propane was prepared by the gas permeation membrane method for the calibration of air pollutant monitoring instruments.
Propane ... is a constituent in the paraffin fraction of crude oil and natural gas ... Propane is odorless when pure; a foul smelling odorant is often added when propane is used for fuel purposes.

説明Propane is colourless and odourless, with a mercaptan odour. Like all fossil fuels, propane is a non-renewable energy source. Propane is a gas derived from natural gas and petroleum. It is found mixed with natural gas and petroleum deposits. Propane is called a ‘fossil fuel’ because it was formed millions of years ago from the remains of tiny sea animals and plants. Propane is a clean-burning, versatile fuel. It is used by nearly everyone, in homes, on farms, by business, and in industry mostly for producing heat and operating equipment. Propane is one of the many fossil fuels included in the liquefied petroleum gas (LPG) family. Because propane is the type of LPG most commonly used in the United States, propane and LPG are often used synonymously. Butane is another LPG often used in lighters.
使用Propane is used as a fuel gas, as a refrigerant,and in organic synthesis.
一般的な説明A colorless gas with a faint petroleum-like odor. PROPANE is shipped as a liquefied gas under its vapor pressure. For transportation PROPANE may be stenched. Contact with the unconfined liquid can cause frostbite by evaporative cooling. Easily ignited. The vapors are heavier than air and a flame can flash back to the source of leak very easily. The leak may be either a liquid or vapor leak. The vapors can asphyxiate by the displacement of air. Under prolonged exposure to fire or heat the containers may rupture violently and rocket.
