MSDS Material Safety Data Sheet (REFRIGERANT R600a - ISOBUTANE) Revision 11/04 1. CHEMICAL PRODUCT AND COMPANY INDENTIFICATION NAME: SHANDONG YUEAN CHEMICAL INDUSTRY CO.,LTD ADDRESS: HEZE,SHANDONG,CHINA 274000 TELEPHONE NUMBER: 0086 – 530- 5725388 MSDS INDENTIFICATION CODE/NUMBER: IA EMERGENCY TELEPHONE NUMBER: 0086 – 530 - 5725388 CHEMTREC PRODUCT NAME: Isobutane CAS NUMBER: 75-28-5 CHEMICAL FAMILY: Aliphatic hydrocarbon CHEMICAL FORMULA: C4H10 SYNONYMS: 2-Methylpropane, Trimethylmethane 2. COMPOSITION/INFORMATION ON INGREDIENTS INGREDINT NAME Isobutene CAS NUMBER:75-28-5 EXPOSURE LIMITS CONCENTRATION PERSENT BY WEIGHT No 99.0-99.9 OSHA PEL -TWA:Simple Asphyxiant 3. HAZARDA INDENTIFICATION This product does not contain oxygen and may cause asphyxia if released in a confined area. Simple Hydrocarbons can cause irritation and central nervous system depression at high concentrations. Extremely Flammable EYE EFFECTS: None anticipated as product is a gas at room temperature. SKIN EFFECTS: None anticipated as product is a gas at room temperature. INGESTION EFFECTS: Ingestion is unlikely. INHALATION EFFECTS: Product is relatively nontoxic. Simple hydrocarbons can irritate the eyes, mucous membranes and respiratory system at high concentrations. Inhalation of high concentrations may cause dizziness, disorientation, in coordination, narcosis, or nausea or narcotic. This product may displace oxygen if released in a confined space. Maintain oxygen levels above 19.5% at sea level to prevent asphyxiation. Effects of oxygen deficiency resulting from simple MSDS asphyxiate may include: rapid breathing, diminished mental alertness, impaired muscular coordination, faulty judgment, depression of all sensations, emotional instability, and fatigue. As asphyxiation progresses, nausea, vomiting, prostration, and loss of consciousness may result, eventually leading to convulsions, coma, and death. Oxygen deficiency during pregnancy has produced development abnormalities in humans and experimental animals. 4. FIRST AID MEASURES EYES Never introduce oil or ointment into the eyes without medical advice! If pain is present, refer the victim to ophthalmologist for further treatment and follow-up. SKIN Remove contaminated clothing and flush affected area with cold water and soap. If irritation persists, seek medical attention. INGESTION Not normally required. Seek immediate medical attention. INHALATION PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF OVEREXPOSURE OT PRODUCT. RESCUE PERSONNEL SHOULD BE EQUIPPED WITH SELF-CONTAINED BREATHING APPARATUS. Conscious persons should be assisted to an uncontaminated area and inhale fresh air. Quick removal from the contaminated area is most important. Unconscious persons should be moved to an uncontaminated area, given assisted(artificial) respiration and supplemental oxygen. Further treatment should be symptomatic and supportive. 5. FIRE FIGHTING MEASURES FLAMMABLE PROPERTIES FLASH POINT: -117℉ (-83℃) Closed Cup AUTOIGNITION: -778℉ (420℃) LOWER EXPLOSIVE LIMIT (%): 1.8 UPPER EXPLOSIVE LIMIT (%): 8.4 FIRE AND EXPLOSION HAZARDS. Isobutene is heavier than air and may travel a considerable distance to an ignition source. Isobutene is a flammable gas! Keep away from open flame and other sources of ignition. Do not allow smoking in storage areas or when handing. EXTINGUISHING MEDIA Water, carbon dioxide, Dry chemical FIRE FIGHTING INSTRUCTIONS MSDS If possible, stop the flow of gas with a remote valve. Use water spray to cool exposed containers. If fire is extinguished and flow of gas is continues, increase ventilation to prevent a build up of a flammable / explosive atmosphere. Extinguish sources of ignition. Be cautious of Boiling Liquid Evaporating Vapor Explosion, BLEVE, if flame is impinging on surrounding containers. Direct a 500 GPM water stream onto containers above the liquid level with remote monitors. Limit the number of personnel in proximity to the fire. Evacuate surrounding area to at least 3000 feet in all directions. 6. ACCIDENTAL RELEASE MEASURES Evacuate all personnel from affected area. Use appropriate protective equipment. Increase ventilation to prevent build up of flammable/explosive atmosphere. Extinguish all sources of ignition! If leak is in container or container valve, contact the appropriate emergency telephone number listed in Section 1 or call Advanced Gas Tech. or CHEMTREC. 7. HANDING AND STORAGE HANDING AND STORAGE PRECAUTIONS Earth bond and ground all lines and equipment associated with the product system. Electrical equipment should be non-sparking and explosion proof. Use only in well-ventilated areas. Valve protection caps must remain in place unless container is secured with valve outlet piped to use point. Do not drag, slide, or roll cylinders. Use a pressure regulator when connecting to lower pressure (250psig) piping or systems. Do not heat cylinder by any means to increase the discharge rate of product from the cylinder. Use a check valve or trap in the discharge line to prevent hazardous back flow into the cylinder. Protect cylinders from physical damage. Store in cool, dry, well-ventilated area away from heavily trafficked areas and emergency exists. Do not allow the temperature where cylinders are stored to exceed 130℉ (54℃). Cylinders should be stored upright and firmly secured to prevent falling or being knocked over. Full and empty cylinders should be segregated. Use a ‘first in – first out’ inventory system to prevent full cylinders from being stored for excessive periods of time. Post “No Smoking” signs in storage or use areas. For additional recommendations consult Compressed Gas Association pamphlet P-1. Never carry a compressed gas cylinder or container of a gas in cryogenic liquid form in as enclosed space such as a car trunk, van or station wagon. A leak can result in a fire, explosion, asphyxiation or a toxic exposure. 8. EXPOSURE CONTROLS/PERSONAL PROTECTION ENGINEERING CONTROLS Use local exhaust to prevent gas from accumulating. Use general ventilation to prevent build up of flammable concentrations. Use a hood with ventilation when handing small quantities. If product is handled routinely where the potential for leaks exists, all electrical equipment must be rated for MSDS use in potentially flammable atmospheres. Consult the National Electrical Code for detail. EYE/FACE PROTECION Safety goggles or glasses SKIN PROTECTION Protective gloved made of plastic of rubber. RESPIRATORY PROTECTION Positive pressure air line with full-face mask and escape bottle or self-contained breathing apparatus should be available for emergency use. OTHER/GENERAL PROTECTION Safety shoes, safety shower, eyewash. 9. PHYSICAL AND CHEMICAL PROPERTIES BASIC PHYSICAL PROPERTIES BOILING POINT: 10.9℉ -11.7℃ MELTING POINT: -255.3 ℉ -159.6℃ VAPOR PRESSURE: (@70 F) 45 psia VAPOR DENSITY (AIR=1): 2.06 SOLUBILITY (H20): Very slight Odor: A colorless, odorless gas. 10.
