Fresh air, rest. Refer for medical attention.

Remove contaminated clothes. Rinse skin with plenty of water or shower.

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

Rinse mouth. Give nothing to drink. Do NOT induce vomiting. Refer immediately for medical attention.

Very high vapor concentrations irritate eyes and upper respiratory tract. Continued contact with skin may cause irritation. (USCG, 1999)

Near borderline between toxicity classes 3 & 4. 4=very toxic: probable oral lethal dose (human) 50-500 mg/kg, between 1 teaspoon & 1 oz for 70 kg person (150 lb). 3= moderately toxic: probable oral lethal dose (human) 0.5-5.0 g/kg, between 1 oz & 1 pint (or 1 lb) .

3-Methyl-1-butanol, following serial (four 15-minute intervals) ip injections in the rat, is very rapidly metabolized . Only 1-1.5% of the administered doses of 3-methyl-1-butanol were excreted in the expired air plus urine as the pentanol. The blood concentration of 3-methyl-1-butanol decreased from 37 mg/100 ml at 1 hr (ie, 15 min after the last pentanol injection) to <1 mg/100 ml at 5 hr. In the rabbit, limited amounts of 3-methyl-1-butanol and the other primary pentanols are conjugated to yield the glucuronide, and 7-10% of the administered dose is excreted as the urinary glucuronide.

Use water, powder, "alcohol" foam or carbon tetrachloride. Water spray is effective for cooling fire-exposed containers, dispersing spills before burning, and protection from heat those persons engaged to stop leakage during the fire.

Excerpt from ERG Guide 129 [Flammable Liquids (Water-Miscible / Noxious)]: 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. (ERG, 2016)

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

Personal protection: protective clothing, safety goggles and filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Collect leaking and spilled liquid in sealable non-plastic containers as far as possible. Absorb liquid in sand or inert absorbent. Wash away remainder with plenty of water.

1. Remove all ignition sources. 2. Ventilate area of spill or leak. 3. For small quantities, absorb on paper towels. Evaporate in a safe place (such as a fume hood). Allow sufficient time for evaporating vapors to completely clear the hood ductwork. Burn the paper in a suitable location away from combustible materials. ... Isoamyl alcohol should not be allowed to enter a confined space, such as a sewer, because of the possibility of an explosion.

NO open flames, NO sparks and NO smoking. Above 42°C use a closed system, ventilation and explosion-proof electrical equipment. 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.

SHOULD BE STORED IN A COOL, WELL-VENTILATED PLACE, OUT OF DIRECT RAYS OF THE SUN, AWAY FROM AREAS OF HIGH FIRE HAZARD, & SHOULD BE PERIODICALLY INSPECTED ...

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

Wear safety spectacles, face shield or eye protection in combination with breathing protection.

Protective gloves. Protective clothing.

Use ventilation, local exhaust or breathing protection.

Decomposes on heating and on burning. This produces irritating fumes. Reacts violently with strong oxidants. Reacts with reducing agents. This generates explosion hazard. Attacks plastics and coatings.

MODERATE, WHEN EXPOSED TO HEAT OR FLAME; CAN REACT VIGOROUSLY WITH REDUCING MATERIALS.ISOAMYL ALCOHOL attacks plastics [Handling Chemicals Safely, 1980. p. 236]. Mixtures with concentrated sulfuric acid and strong hydrogen peroxide may cause explosions. Mixing with hypochlorous acid in water or water/carbon tetrachloride solution can generate isoamyl hypochlorites, which may explode, particularly on exposure to sunlight or heat. Mixing with chlorine would also yield isoamyl hypochlorites [NFPA 491 M, 1991]. Base-catalysed reactions with isocyanates can occur with explosive violence [Wischmeyer,1969].

The substance is severely irritating to the eyes. The substance is irritating to the respiratory tract. The substance is mildly irritating to the skin. Ingestion could cause effects on the central nervous system. If swallowed the substance may cause vomiting and could result in aspiration pneumonitis.

The substance defats the skin, which may cause dryness or cracking.

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

Isopentanol is readily biodegraded in aerobic screening tests using sewage or activated sludge inocula(1-5). In one screening study utilizing a sewage seed, 75% and 100% of the isopentanol degraded within 4.5 and 6 days, respectively(1). In another, the half-life of isopentanol was 2.4 days(2). Five day BOD values ranged from 49% to 77% of theoretical(3-5). In a semi-continuous activated sludge treatment plant simulation, a 47% BOD reduction was achieved in 8 hr(3). The half-lives of isopentanol in ground water, Lester River, MN river water and Lake Superior harbor water were 15, 11, and 6.1 days, respectively(6). Isopentanol was >75% mineralized when incubated for 8 weeks in an anaerobic reactor using a 10% sludge inoculum from a secondary digester(7). The mean removal rate of isopentanol from a semi-pilot scale anaerobic lagoon was 32% in 20 days(8).

The BCF for isopentanol estimated from isopentanol's octanol/water partition coefficient, log 1.42(1), using a recommended regression equation is 7(2). Such a low BCF would indicate that isopentanol would not bioconcentrate in aquatic organisms(SRC).

The Koc for isopentanol estimated from its water solubility, 26.7 mg/L(1), using recommended regression equations are 720(2) and 679(4). However, the chemicals used in developing these equations were mainly pesticides and their structures are not similar to isopentanol. The Koc for isopentanol estimated from molecular structure is 4(3). This should be a reasonable estimate for the Koc because it is close to the experimental value for the structurally similar chemical, 1-pentanol, 1.6(6). According to a suggested classification scheme(5), the estimated Kocs based on molecular structure suggests that isopentanol is very highly mobile in soil(SRC).

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.
