Use personal protective equipment. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. For personal protection see section 8.6.2 Environmental precautions
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. Do NOT let this chemical enter the environment. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Do NOT wash away into sewer.6.3 Methods and materials for containment and cleaning up
Environmental considerations: air spill: Apply water spray or mist to knock down vapors. /Pentanes/7.Handling and storage 7.1 Precautions for safe handling

Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at the end of workday.8.3 Individual protection measures, such as personal protective equipment (PPE) Eye/face protection
Safety glasses with side-shields conforming to EN166. Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).Skin protection
Wear impervious clothing. The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace. Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique(without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.Respiratory protection
Wear dust mask when handling large quantities.Thermal hazards

- Toxicity to daphnia and other aquatic invertebrates: no data available
- Toxicity to algae: no data available
- Toxicity to microorganisms: no data available
AEROBIC: Organisms isolated from groundwater contaminated by a gasoline spill were found to grow when inoculated with pure samples of isopentane; however, no biodegradation of isopentane was observed when a mixed culture of these organisms was inoculated with gasoline(1). 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(2). Following a 6.1 day lag period, isopentane was completely degraded using an activated sludge over the course of a 20 day incubation period under aerobic conditions(3). The half-life of a mixture containing isopentane, pentane, and cyclopentane in seawater was 2.4 days(4).12.3 Bioaccumulative potential
An estimated BCF of 70 was calculated in fish for isopentane(SRC), using a water solubility of 48 mg/L(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 isopentane is estimated as 520(SRC), using a water solubility of 48 mg/L(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that isopentane is expected to have low mobility in soil(SRC).12.5 Other adverse effects
no data available13.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.14.Transport information 14.1 UN Number
