No. 674 ISOBUTYLENE 11/88
<br /> SECTION..6. HEALTH<HAZA'RD. INFORMATION cont.
<br /> lene gas is almost twice as dense as air itself(see sect.3).Medical Conditions Aggravated by Long-Term Exposure None reported
<br /> Target Organs: None reported.Primary Entry: Inhalation.Acute Effects: Initial symptoms of the effects of simple asphyxiant
<br /> gases are rapid respiration and air hunger,diminished mental alertness,and impaired muscular coordination.Continuing lack of oxygen
<br /> causes faulty judgment,depression of all sensations,rapid fatigue,and emotional instability.As the asphyxia continues,nausea;vomit-
<br /> ing;prostration;loss of consciousness;and,finally,convulsions;deep coma;and death can occur.Chronic Effects: None reported.
<br /> FIRST AID: Inhalation.Would-be rescuers need to be concerned about their own safety when entering confined,poorly ventilated,
<br /> oxygen-deficient areas.Self-contained breathing equipment must be readily available for rescuers.Station standby workers outside the
<br /> immediate area so that they can summon additional help if it is needed.Remove the exposed person to fresh air;restore and/or support
<br /> his or her breathing as needed.Have qualified medical personnel administer oxygen as required.Comments: The extreme flammability
<br /> of isobutylene gas warrants special attention even during rescue operations.Rescue personnel must not smoke.All emergency lamps and
<br /> floodlights that must be lowered into enclosed areas for rescue operations must be explosion proof.Obtain this equipment before any
<br /> emergency occurs and make it accessible to emergency-response personnel.Get medical help(in plant,paramedic,community)for
<br /> all exposures.Seek prompt medical assistance for further treatment,observation,and support after fust aid.
<br /> SECTION 7 . SPILL . IEAK AND 'DISPOSAL 'PROCEDURES
<br /> Spill/Leak:Treat any isobutylene gas leak as an emergency.If the leaking gas has not yet ignited,use water spray to direct flammable gas-
<br /> air mixtures away from sources of ignition.Extinguish all sources of ignition as quickly as possible;however,if the leaking gas is burning,
<br /> do not attempt to extinguish the flames until the source of the isobutylene gas is located and sealed.Otherwise,flammable isobutylene gas-
<br /> air mixtures can explode without warning and cause widespread damage that might not have occurred if the original fire had been allowed
<br /> to burn itself out.If it is necessary to extinguish isobutylene flames in order to gain access to a shutoff valve,use dry chemical or carbon
<br /> dioxide as extinguishing agents.Waste Disposal: Contact your supplier or a licensed contractor for detailed recommendations.Follow
<br /> Federal,state,and local regulations.
<br /> OSHA Designations
<br /> Air Contaminant(29 CFR 1910.1000 Subpart Z):Not Listed
<br /> EPA Designations(40 CFR 302.4): Not Listed
<br /> SECTION 8. SPECIAL PROTECTION INFORMATION
<br /> Respirator: Follow OSHA respirator regulations(29 CFR 1910.134).For emergency or nonroutine operations(leaks or cleaning reactor
<br /> vessels and storage tanks),wear an SCBA.Warning: Air-purifying respirators will not protect workers in oxygen-deficient atmospheres,
<br /> which lack warning properties;to work in them safely requires that an SCBA be worn.Ventilation: Install and operate general and local
<br /> maximum,explosion-proof ventilation systems powerful enough to maintain airborne levels of this material below the lower explosive limit
<br /> cited in section 4.Local exhaust ventilation is preferred because it prevents dispersion of the contaminant into the general work area by
<br /> eliminating it at its source.Consult the latest edition of Genium reference 103 for detailed recommendations.Safety Stations: Make emer-
<br /> gency eyewash stations,safety/quick-drench showers,and washing facilities available in work areas.Contaminated Equipment: Contact
<br /> lenses pose a special hazard;soft lenses may absorb irritants,and all lenses concentrate them.Do not wear contact lenses in any work area.
<br /> Comments: Practice good personal hygiene;always wash thoroughly after using this material and before eating,drinking,smoking,using
<br /> the toilet,or applying cosmetics.Keep it off your clothing and equipment.Avoid transferring it from your hands to your mouth while eating,
<br /> drinking,or smoking.Do not eat,drink,or smoke in any work area.Do not inhale isobutylene vapor.
<br /> SECTION 9. SPECIAL PRECAUTIONS> AND. COMMENTS
<br /> Storage/Segregation:Store isobutylene in closed,pressurized containers in a cool,dry,well-ventilated area away from sources of ignition,
<br /> combustible materials,and strong oxidizers.Protect containers from physical damage.Engineering Controls: Make sure all engineering
<br /> systems(production,transportation)are of maximum explosion-proof design.Electrically ground and bond all containers,pipelines,etc.,
<br /> used in shipping,transferring,reacting,production,and sampling operations to prevent static sparks.Comments: isobutylene is an
<br /> extremely explosive and flammable gas.It must not be exposed to any possible source of ignition in work or storage areas.
