Contact with combustible material may cause fire. May form explosive peroxides. HARMFUL - May cause lung damage if swallowed. Harmful in contact with skin and if swallowed. Irritating to eyes, respiratory system and skin. Highly flammable. Vapours may cause drowsiness and dizziness. POTENTIAL HEALTH EFFECTS ACUTE HEALTH EFFECTS SWALLOWED ! Accidental ingestion of the material may be harmful; animal experiments indicate that ingestion of less than 150 gram may be fatal or may produce serious damage to the health of the individual. ! Swallowing of the liquid may cause aspiration into the lungs with the risk of chemical pneumonitis; serious consequences may result. (ICSC13733). EYE ! This material can cause eye irritation and damage in some persons. SKIN ! Skin contact with the material may be harmful; systemic effects may resultfollowing absorption. ! This material can cause inflammation of the skin oncontact in some persons. ! The material may accentuate any pre-existing dermatitis condition. ! Repeated exposure may cause skin cracking, flaking or drying following normal handling and use. ! Open cuts, abraded or irritated skin should not be exposed to this material. ! Entry into the blood-stream, through, for example, cuts, abrasions or lesions, may produce systemic injury with harmful effects. Examine the skin prior to the use of the material and ensure that any external damage is suitably protected. INHALED ! The material can cause respiratory irritation in some persons. The body's response to such irritation can cause further lung damage. ! Inhalation of vapours may cause drowsiness and dizziness. This may be accompanied by narcosis, reduced alertness, loss of reflexes, lack of coordination and vertigo. ! Inhalation of vapors or aerosols (mists, fumes), generated by the material during the course of normal handling, may be damaging to the health of the individual. ! Inhalation hazard is increased at higher temperatures. ! Inhalation of high concentrations of gas/vapor causes lung irritation with coughing and nausea, central nervous depression with headache and dizziness, slowing of reflexes, fatigue and inco-ordination. ! Central nervous system (CNS) depression may include general discomfort, symptoms of giddiness, headache, dizziness, nausea, anaesthetic effects, slowed reaction time, slurred speech and may progress to unconsciousness. Serious poisonings may result in respiratory depression and may be fatal. CHRONIC HEALTH EFFECTS ! Long-term exposure to respiratory irritants may result in disease of the airways involving difficult breathing and related systemic problems. Limited evidence suggests that repeated or long-term occupational exposure may produce cumulative health effects involving organs or biochemical systems. Chronic solvent inhalation exposures may result in nervous system impairment and liver and blood changes. [PATTYS]. Section 3 - COMPOSITION / INFORMATION ON INGREDIENTS NAME CAS RN % cyclopentene 142-29-0 >98 commercial product inhibited with hydroquinone 123-31-9 0.1 2 of 12 Section 4 - FIRST AID MEASURES SWALLOWED · If swallowed do NOT induce vomiting. · If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain open airway and prevent aspiration. · Avoid giving milk or oils. · Avoid giving alcohol. · If spontaneous vomiting appears imminent or occurs, hold patient's head down, lower than their hips to help avoid possible aspiration of vomitus. EYE ! If this product comes in contact with the eyes: · Wash out immediately with fresh running water. · Ensure complete irrigation of the eye by keeping eyelids apart and away from eye and moving the eyelids by occasionally lifting the upper and lower lids. SKIN ! If skin contact occurs: · Immediately remove all contaminated clothing, including footwear · Flush skin and hair with running water (and soap if available). INHALED · If fumes or combustion products are inhaled remove from contaminated area. · Lay patient down. Keep warm and rested. NOTES TO PHYSICIAN ! Any material aspirated during vomiting may produce lung injury. Therefore emesis should not be induced mechanically or pharmacologically. For acute or short term repeated exposures to petroleum distillates or related hydrocarbons: · Primary threat to life, from pure petroleum distillate ingestion and/or inhalation, is respiratory failure. · Patients should be quickly evaluated for signs of respiratory distress (e.g. cyanosis, tachypnea, intercostal retraction, obtundation) and given oxygen. Patients with inadequate tidal volumes or poor arterial blood gases (pO2 50 mm Hg) should be intubated. Section 5 - FIRE FIGHTING MEASURES Vapor Pressure (mmHg): 315.776 @ 20 C Upper Explosive Limit (%): Not available Specific Gravity (water=1): 0.774 Lower Explosive Limit (%): 1.5 EXTINGUISHING MEDIA · Foam. · Dry chemical powder. FIRE FIGHTING · Alert Emergency Responders and tell them location and nature of hazard. · May be violently or explosively reactive. When any large container (including road and rail tankers) is involved in a fire, consider evacuation by 500 metres in all directions. GENERAL FIRE HAZARDS/HAZARDOUS COMBUSTIBLE PRODUCTS · Liquid and vapor are highly flammable. · Severe fire hazard when exposed to heat, flame and/or oxidizers. Combustion products include: carbon dioxide (CO2), other pyrolysis products typical of burning organic material. Contains low boiling substance: Closed containers may rupture due to pressure buildup under fire conditions. WARNING: Long standing in contact with air and light may result in the formation of potentially explosive peroxides. FIRE INCOMPATIBILITY ! Avoid contamination with oxidizing agents i.e. nitrates, oxidizing acids,chlorine bleaches, pool chlorine etc. as ignition may result. PERSONAL PROTECTION Glasses: Chemical goggles. Gloves: Respirator: Type AX Filter of sufficient capacity Section 6 - ACCIDENTAL RELEASE MEASURES MINOR SPILLS · Remove all ignition sources. · Clean up all spills immediately. MAJOR SPILLS ! CARE: Absorbent material wet with occluded oil must be wet with water as they may auto-oxidize, become self heating and ignite. Some oils slowly oxidize when spread in a film and oil on cloths, mops, absorbents may auto-oxidize and generate heat, smoulder, ignite and burn. In the workplace oily rags should be collected and immersed in water. · Clear area of personnel and move upwind. 3 of 12 · Alert Emergency Responders and tell them location and nature of hazard. Section 7 - HANDLING AND STORAGE PROCEDURE FOR HANDLING · Containers, even those that have been emptied, may contain explosive vapours. · Do NOT cut, drill, grind, weld or perform similar operations on or near containers. · Electrostatic discharge may be generated during pumping - this may result in fire. · Ensure electrical continuity by bonding and grounding (earthing) all equipment. · Restrict line velocity during pumping in order to avoid generation of electrostatic discharge (<=1 m/sec until fill pipe submerged to twice its diameter, then <= 7 m/sec). · Avoid splash filling. · Do NOT use compressed air for filling discharging or handling operations. · Avoid all personal contact, including inhalation. · Wear protective clothing when risk of exposure occurs. Contains low boiling substance: Storage in sealed containers may result in pressure buildup causing violent rupture of containers not rated appropriately. · Check for bulging containers. · Vent periodically. · DO NOT allow clothing wet with material to stay in contact with skin. RECOMMENDED STORAGE METHODS ! Glass container. Packing as supplied by manufacturer. Plastic containers may only be used if approved for flammable liquid. · For low viscosity materials (i): Drums and jerricans must be of the non-removable head type. (ii): Where a can is to be used as an inner package, the can must have a screwed enclosure. · For materials with a viscosity of at least 2680 cSt. (23 deg. C). STORAGE REQUIREMENTS · Store in original containers in approved flame-proof area. · No smoking, naked lights, heat or ignition sources.
