Description of first aid measures
If inhaledFresh air, rest. Refer for medical attention.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Seek medical attention if you feel unwell.
Rinse with plenty of water (remove contact lenses if easily possible). Refer for medical attention.
Rinse mouth. Do NOT induce vomiting. Refer immediately for medical attention.
Most important symptoms and effects, both acute and delayed
Irritation of skin, eyes, and respiratory tract; headache and vertigo; dyspnea and cough; nausea, vomiting, and diarrhea. Double vision, deafness, delirium, and occasionally fatal poisoning, preceded by severe nervous symptoms, have been reported. Coma, glycosuria, and methemoglobinemia can occur. (USCG, 1999)
Indication of any immediate medical attention and special treatment needed
There is no antidote for intoxication /of pentyl alcohols/. If symptoms develop, the victim should be removed from the contaminated area and given supportive treatment if it is needed. Pentyl alcohols
Extinguishing media
Extinguish with dry chemical, alcohol foam, or carbon dioxide. Water may be ineffective on fire. Cool exposed containers with water.
Specific Hazards Arising from the Chemical
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)
Advice for firefighters
Wear self-contained breathing apparatus for firefighting if necessary.
Personal precautions, protective equipment and emergency procedures
Avoid dust formation. Avoid breathing mist, gas or vapours.Avoid contacting with skin and eye. Use personal protective equipment.Wear chemical impermeable gloves. Ensure adequate ventilation.Remove all sources of ignition. Evacuate personnel to safe areas.Keep people away from and upwind of spill/leak.
Environmental precautions
Remove all ignition sources. Personal protection: filter respirator for organic gases and particulates adapted to the airborne concentration of the substance. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.
Methods and materials for containment and cleaning up
Environmental considerations: Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. Dike surface flow using soil, sand bags, foamed polyurethane, or foamed concrete. Absorb bulk liquid with fly ash, cement powder, or commercial sorbents. pentanols
Precautions for safe handling
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.
Conditions for safe storage, including any incompatibilities
Fireproof. Separated from strong oxidants.Fireproof. Separated from strong oxidants, and alkaline metals and alkaline-earth metals. Keep in a well-ventilated room.

Exposure controls
Ensure adequate ventilation. Handle in accordance with good industrial hygiene and safety practice. Set up emergency exits and the risk-elimination area.
Individual protection measures
Eye/face protectionWear tightly fitting safety goggles with side-shields conforming to EN 166(EU) or NIOSH (US).
Wear fire/flame resistant and impervious clothing. Handle with gloves. Gloves must be inspected prior to use. 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.
If the exposure limits are exceeded, irritation or other symptoms are experienced, use a full-face respirator.

Persistence and degradability
AEROBIC: In 5-day BOD tests with sewage as microbial inoculum, the oxygen consumption of n-pentyl alcohol ranged from 59 to 86.9% of the theoretical BOD(1,4-7). In a Warburg test with activated sludge as inoculum, the oxygen consumption at 1 day of incubation was 28% of the theoretical value(3). At concentrations above 300 mg/L, n-pentyl alcohol may have an inhibitory effect on the oxidative respiratory rate in the presence of activated sludge(8). The first order rate constants (at a constant microorganism concn) for biodegradation of n-pentyl alcohol in non-adapted activated sludge was 0.0285 per hr(2) corresponding to an aerobic biodegradation half-life of 1 day.
Bioaccumulative potential
An estimated BCF of 3 was calculated for n-pentyl alcohol(SRC) using a log Kow of 1.51(1) and a regression derived equation(2). Based on a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
The Koc of n-pentyl alcohol is estimated as 160(SRC), using a log Kow of 1.51(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that n-pentyl alcohol is expected to have moderate mobility in soil.
Other adverse effects

Disposal methods
ProductThe 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.
