Rinse mouth.

Inhalation causes irritation of respiratory tract, cough, mild depression, cardiac arrhythmias. Aspiration causes severe lung irritation, coughing, pulmonary edema; excitement followed by depression. Ingestion causes nausea, vomiting, swelling of abdomen, headache, depression. (USCG, 1999)

Excerpt from ERG Guide 128 [Flammable Liquids (Water-Immiscible)]: Inhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution. (ERG, 2016)

Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on the left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. Aliphatic hydrocarbons and related compounds

Wear self contained breathing apparatus for fire fighting if necessary.

Excerpt from ERG Guide 128 [Flammable Liquids (Water-Immiscible)]: HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Those substances designated with a (P) may polymerize explosively when heated or involved in a fire. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water. Substance may be transported hot. For hybrid vehicles, ERG Guide 147 (lithium ion batteries) or ERG Guide 138 (sodium batteries) should also be consulted. If molten aluminum is involved, refer to ERG Guide 169. (ERG, 2016)

Use alcohol-resistant foam, powder, carbon dioxide, water. In case of fire: keep drums, etc., cool by spraying with water.

Evacuate danger area! Consult an expert! Personal protection: filter respirator for organic gases and vapours of low boiling point adapted to the airborne concentration of the substance. Remove all ignition sources. Ventilation. Do NOT wash away into sewer. Do NOT let this chemical enter the environment. Collect leaking and spilled liquid in sealable non-plastic containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Wash away remainder with plenty of water. Then store and dispose of according to local regulations.

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). Do NOT use compressed air for filling, discharging, or handling. 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.

Fireproof. Separated from strong oxidants.Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage.

Ensure adequate ventilation. Handle in accordance with good industrial hygiene and safety practice. Set up emergency exits and the risk-elimination area.

Wear safety goggles.

Protective gloves.

Use ventilation, local exhaust or breathing protection.

Reacts violently with oxidants. This generates fire and explosion hazard. Attacks plastics.

Stable under recommended storage conditions.

The vapour is heavier than air and may travel along the ground; distant ignition possible. As a result of flow, agitation, etc., electrostatic charges can be generated.Saturated aliphatic hydrocarbons, such as ISOHEXENE, may be incompatible with strong oxidizing agents like nitric acid. Charring of the hydrocarbon may occur followed by ignition of unreacted hydrocarbon and other nearby combustibles. In other settings, aliphatic saturated hydrocarbons are mostly unreactive. They are not affected by aqueous solutions of acids, alkalis, most oxidizing agents, and most reducing agents.

The substance and the vapour are mildly irritating to the eyes, respiratory tract and skin. If swallowed the substance easily enters the airways and could result in aspiration pneumonitis. The substance may cause effects on the central nervous system. This may result in lowering of consciousness.

The substance defats the skin, which may cause dryness or cracking. Repeated or prolonged contact with skin may cause dermatitis.

A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C.

AEROBIC: Indigenous soil microbes will biodegrade petroleum hydrocarbons under aerobic conditions(1). A quarter of the microorganisms isolated from gasoline-contaminated groundwater, most notably of the Nocardia sp., supported growth of 2-methylpentane(2). Generally iso-alkanes are significantly more resistant to microbial attack than n-alkanes(3). However, a soil microorganism, Corynebacterium sp. oxidized 2-methylpentane, at about the same rate as n-pentane, although at a significantly lower rate than n-hexane(3). 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(4). The biodegradation half-lives of the C6-saturates compound group (n-hexane, 2-methylpentane, 3-methylpentane, methylcylcopentane and cyclohexane), determined from biodegradation tests with water accommodated fractions(WAF) of Statjofrd fresh oil, Aquila fresh oil, and Marine diesel in seawater at 13 deg C, were 2.8, 1.7, and 3.5 days respectively (without correction for lag phase) (5). The mean half-life from results for all three oils was determined to be 2.7 days for the C6-saturates group(5). 2-Methylpentane, and 10 other components of gasoline were completely degraded in a screening study using an activated sludge inoculum in less than 34 days(6). A mixture containing isopentane, pentane, cyclopentane, 2,3-dimethylbutane, 2-methylpentane, 3-methylpentane, and cyclohexane, showed little degradation over the course of 30 days in a sediment/groundwater obtained from a contaminated jet fuel site in Oscoda, MI(7). 2-Methylpentane, present at 100 mg/L, reached 93% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in a screening test assessing biodegradation in water(8). Therefore, 2-methylpentane is confirmed to be readily biodegradable according to the standard test of the Japanese Ministry of Industry and Trade (MITI) (8).

An estimated BCF of 61 was calculated in fish for 2-methylpentane(SRC), using an estimated log Kow of 3.21(1) and a regression-derived equation(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate(SRC).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of 2-methylpentane can be estimated to be 610(SRC). According to a classification scheme(2), this estimated Koc value suggests that 2-methylpentane is expected to have low mobility in soil. A sorption experiment using lignite samples resulted in a log Kd of 2.92 for 2-methylpentane(3).

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.

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.
