. HAZARDS IDENTIFICATION Chemical Name CAS No. Labeling Classification Code H-code Signal Word H 280 H 220 Danger Hazard Pictogram Press. Gas R600 75-28-5 Classification of the substance Hazard Statement Precautionary Statement Flam. Gas 1 Flam. Gas I : Flammable gases category I Press. Gas : Gases under pressure (Liquefied gas) H 220 : Extremely flammable gas H 280 : Contains gas under pressure; may explode if heated. OSHA H01 : May displace oxygen and cause rapid suffocation.
P 381 : Eliminate all ignition sources if safe to do so. P 304, P 340, P 313 : IF INHALED: Remove victim to fresh air and keep at rest in a position comfortable for breathing. Get medical advice /attention. P 302, P 336, P 315 : IF ON SKIN: Thaw frosted parts with lukewarm water. Do not rub affected area. Get immediate medical advice/attention. CGA-PG02 : Protect from sunlight when ambient temperature exceeds 52 o C (125oF). CGA-PG05 : Use a back flow preventive device in the piping.
Precautionary Statement P210 : Keeps away from heat/ sparks/ open flames/ hot surfaces – No smoking. P377 : Leaking gas fire: Do not extinguish, unless leak can be stopped safely. P381 : Eliminate all ignition sources if safe to do so. P403 : Store in a well-ventilated place Contact with liquid or cold vapor can cause frostbite. Forms explosive mixture with air and oxidizing agents. Other Hazards 3.
Inhalation Victims should be assisted to an uncontaminated area is most important. Move exposed person to fresh air. If not breathing, provide artificial respiration or oxygen by trained personnel. In the event of cardiac arrest apply external cardiac massage. Further treatment should be symptomatic and supportive. Keep victim warm and quiet. PROMPT MEDICAL ATTENTION IS MANDAROTY IN ALL CASES OF OVEREXPOSURE. RESCUE PERSONNEL SHOULD BE EQUIPPED WITH SELF-CONTAINED BREATHING APPARATUS.
5. FIRE FIGHTING MEASURES Suitable extinguishing media Alcohol-resistant foam. Carbon dioxide (CO2). Dry Chemical. Unsuitable extinguishing media Water Jet. Special hazards arising from the chemical Exposure to fire may cause containers to rupture/explode. Vapor is heavier than air, may travel long distances along the ground before reaching a source of ignition and flashing back. When mixed with air and exposed to ignition source, vapors can burn in open or explode if confined.
6. ACCIDENTAL RELEASE MEASURES Personal precautions Ensure suitable personal protection (including respiratory protection) during removal of spillages. Evacuate surrounding areas. Ensure adequate ventilation. Keep unnecessary and unprotected personnel from entering. Beware of vapors accumulating to form explosive concentrations. Vapors can accumulate in low areas. Environmental precautions If safe to do so: isolate the source of the leak. Try to stop release.
7. HANDLING AND STORAGE Precaution for safe handling Avoid inhalation of high concentrations of vapors. Atmospheric level should be controlled in compliance with the occupational exposure limit. Atmospheric concentrations well below the occupational exposure limit can be achieved by good occupational hygiene practice. The vapor is heavier than air, high concentrations may be produced at low levels where general ventilation is poor.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION Exposure Limit: OSHA-PEL Control parameters Chemical Name R600a (Isobutane) Eight-hour time-weighted airborne concentration ppm mg/m3 - - average Exposure Limit: ACGIH TLV Short Term Limit Exposure Limit (STEL) Chemical Name ppm R600a (Isobutane) Appropriate controls engineering Personal protection equipment 1000 Use local exhaust and general ventilation system, not only to control exposure but also to prevent formation of flammable mixtures.
9. PHYSICAL AND CHEMICAL PROPERTIES Appearance : Colorless, Liquefied gas Odour : Sweet petroleum odor. Odour threshold : Odour threshold is subjective and inadequate to warn for over exposure. pH : Not applicable Melting point / Freezing point : -159 oC Boiling point : -12 oC Flash point : -87 oC Evaporation rate : Not available Flammability : Extremely flammable Upper/lower explosive limit : UPPER: 8.4 vol% Vapour pressure : 31 psig Vapour density (Air =1) : 2.006.
10. STABILITY AND REACTIVITY Reactivity No reactivity hazard other than the effects described in subsections below. Chemical Stability Stable. Possibility of hazardous reactions Not expected to occur. Vapors may form explosive mixture with air. Condition to avoid Keep away from heat/sparks/open flames/hot surfaces – No smoking. Oxidizing conditions. Incompatible materials Strong oxidizing agents. Acids. Hazardous decomposition products Carbon monoxide, volatile hydrocarbon vapors.
