International Chemical Safety Cards 1-DECENE ICSC: 1477 Decylene alpha-Decene n-1-Decene C10H20 Molecular mass: 140.26 ICSC #    1477 CAS #     872-05-9 RTECS # HE2071401 UN #        1993 November 28, 2003 Peer reviewed TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Flammable. NO open flames, NO sparks, and NO smoking. Powder, alcohol-resistant foam, water spray, carbon dioxide. EXPLOSION Above 46°C explosive vapour/air mixtures may be formed. Above 46°C use a closed system, ventilation, and explosion-proof electrical equipment. Prevent build-up of electrostatic charges (e.g., by grounding). In case of fire: keep drums, etc., cool by spraying with water. EXPOSURE  •INHALATION Ventilation, local exhaust, or breathing protection. Fresh air, rest.  •SKIN Dry skin. Protective gloves. Rinse skin with plenty of water or shower.  •EYES Safety spectacles. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Do not eat, drink, or smoke during work. Rinse mouth. Do NOT induce vomiting. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Remove all ignition sources. Collect leaking liquid in covered containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT let this chemical enter the environment. (Extra personal protection: P2 filter respirator for harmful particles.) Fireproof.

No modifications to the International version have been made except to add the OSHA PELs, NIOSH RELs and NIOSH IDLH values.

International Chemical Safety Cards 1-DECENE ICSC: 1477 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS LIQUID PHYSICAL DANGERS: As a result of flow, agitation, etc., electrostatic charges can be generated. CHEMICAL DANGERS: Attacks plasticandrubber. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. MAK not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its aerosol. INHALATION RISK: No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C. EFFECTS OF SHORT-TERM EXPOSURE: If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The liquid defats the skin.
