  • Common names and synonyms: Cyclopentane
  • CAS number: 287-92-3
  • EC number: 206-016-6
  • Concentration: 100%

SECTION 4: First aid measures

Description of necessary first-aid measures

If inhaled

Fresh air, rest. Refer for medical attention.

Following skin contact

Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention .

Following eye contact

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

Following ingestion

Rinse mouth. Do NOT induce vomiting. Refer immediately for medical attention.

Most important symptoms/effects, acute and delayed

Inhalation causes dizziness, nausea, and vomiting; concentrated vapor may cause unconsciousness and collapse. Vapor causes slight smarting of eyes. Contact with liquid causes irritation of eyes and may irritate skin if allowed to remain. Ingestion causes irritation of stomach. Aspiration produces severe lung irritation and rapidly developing pulmonary edema; central nervous system excitement followed by depression. (USCG, 1999)

Indication of immediate medical attention and special treatment needed, if necessary

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 as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on 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

SECTION 5: Firefighting measures

Suitable extinguishing media

Use dry chemical, carbon dioxide, or foam extinguishers. Water may be ineffective because of low flash point. Do not extinguish fire unless flow of chemical can be stopped.

Specific hazards arising from the chemical

Behavior in Fire: Containers may explode. (USCG, 1999)

Special protective actions for fire-fighters

Use foam, carbon dioxide, powder. Water may be ineffective. In case of fire: keep drums, etc., cool by spraying with water.

SECTION 6: Accidental release measures

Methods and materials for containment and cleaning up

Accidental Release Measures: Personal precautions, protective equipment and emergency procedures Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Remove all sources of ignition. Evacuate personnel to safe areas. Beware of vapours accumulating to form explosive concentrations. Vapours can accumulate in low areas. Environmental precautions: Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the environment must be avoided. Methods and materials for containment and cleaning up: Contain spillage, and then collect with an electrically protected vacuum cleaner or by wet-brushing and place in container for disposal according to local regulations.

SECTION 7: Handling and storage

Precautions for safe handling

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). Use non-sparking handtools. 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.

Conditions for safe storage, including any incompatibilities

Fireproof. Well closed. Separated from strong oxidants and food and feedstuffs. Store in an area without drain or sewer access. Provision to contain effluent from fire extinguishing.Conditions for safe storage, including any incompatibilities: Keep container tightly closed in a dry and well-ventilated place.

STOT-single exposure

The substance and the vapour in high concentrations are irritating to the eyes and respiratory tract. The substance is irritating to the gastrointestinal tract. 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.

STOT-repeated exposure

Repeated or prolonged contact with skin may cause dryness and cracking and dermatitis.

Aspiration hazard

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

  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

Persistence and degradability

AEROBIC: Mixed populations of microorganisms from groundwater contaminated with gasoline did not biodegrade cyclopentane; cyclopentane had an initial concentration of 0.17 ppm in the gasoline mixture, and after 192 hours the concentration was 0.04 ppm. However, the concentration of the control was 0.05 ppm(1). A mixture of C5-saturates, including cyclopentane, had a half-life of 2.4 days in seawater and a water accommodated fraction (WAF)(2).

Bioaccumulative potential

An estimated BCF of 44 was calculated in fish for cyclopentane(SRC), using a log Kow of 3(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

Mobility in soil

The Koc of cyclopentane is estimated as 401(SRC), using a log Kow of 3(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that cyclopentane is expected to have moderate mobility in soil.

Other adverse effects

no data available

SECTION 13: Disposal considerations

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.
