FOREWORD
This Indian Standard was adopted by the Bureau of Indian Standards, after the draft finalized by the ChemicalHazards Sectional Committee had been approved by the Chemical Division Council.
1,3-Butadiene is commercially produced by cracking of naphtha and subsequent fractionation or extractivedistillation. It can also be produced by dehydrogenation of butanes or butenes.
1,3-Butadiene is chiefly used as the principal monomer for the manufacture of various grades of rubber, namely,Styrene butadiene rubber (SBR), Acrylonitrile butadiene styrene rubber (ABS) or Polybutadiene rubber (PBR).It also finds its use in rocket fuels, in plastics and resins.
There is no 1S0 standard on this subject. In preparation of this code assistance has been derived from thefollowing publications:

4.3 Chemical Properties
4.3.1 Peroxide Formation and Polymerization
Uninhibited butadiene combines with oxygen or airto form explosive peroxides and popcorn polymers.Being a diene aliphatic hydrocarbon, it is highlyreactive to form polymers/rubbers like PBR, SBR,ABS. 1,3-butadiene forms 3 types of polymers:
a)
b)
c)
Dimer — Dimer formation takes place at alltemperature and rate of dimer formation in-creases with increasing temperature and hasa tendency to depositon the walls of the con-tainer. To a great extent it is soluble in liquidbutadiene. Inhibitor minimizes the formationof the dimer. Storage at 100C or below canminimize dimer formation.
Heavy polymer — This is dark rubber likematerial, forms in liquid phase and can causeplugging of lines and equipment. Presenceof peroxides tends to produce this polymer.The solid polymer may ignite spontaneouslywhen exposed to the air and must be keptwet until removed from the hazardous area,and if possible, destroyed under supervision(see 4.4.4).
Popcorn polymers — This is formed undernormal processing conditions in the vapourphase. It is tough and resinous. Trace of oxy-gen, oxidizing agents and the presence of seedof popcorn polymer will initiate the format-ion.
4.3.2 Reaction with Oxides of Nitrogen
Butadiene reacts with oxides of nitrogen to formunstable compounds which when heated can causeexplosion even in inert atmosphere.
4.4 Fire and Explosion Hazard Properties
4.4.1 Flash Point, “C — (–)18
4.4.2 Auto Ignition Temperature, “C — 420
4.4.3 Explosive Limits in Air, Percent (v/v)
Lower Explosive Limit (LEL) :2
Upper Explosive Limit (UEL) :11,5
4.4.4 Butadiene vapours being heavier than air, tendto spread and flash back from ignition source. Storageof uninhibited butadiene may present a special hazard,if it is subjected to elevated temperature on account ofwhich it would rapidly polymerize, generating heat,pressure and rupture of the vessel and explosion.Further, oxidizing agents, phenols, aldehydes, rust(iron oxides), oxides of nitrogen, nitrates carbonyls,oxygen, air would cause serious fire and explosionhazard when come into contact with butadiene with alittle friction or heat. Butadiene derived fi-omnaphthacontains trace of acetylenes therefore, should not beallowed to come in contact with acetylide formingmetals, such as, copper, silver, magnesium, mercury,alkali metals and alloys thereof. Acetylides of thesemetals are unstable and could be ignited by friction ofheat to explode. In view of above the recommendedmaximum allowable concentration in refinedbutadiene are following:
Acetylene : 65 ppm
Carbonyls : 100 ppm
Vinyl Acetylene: 150 ppm
The vapours of butadiene, if not inhibited can formpolymers in vents or flame arrestors of storage tanks,causing their blockage.
In butadiene refining columns, the presence of vinylacetylene in butadiene vapour phase should not beallowed to go beyond 40 moles percent because vinylacetylene may initiate explosion above this limit.
Polymerization of butadiene is accelerated by rustyiron. In order to minimize this, iron surface should betreated with 2-3 percent NaN02 which subsequentlyshould be washed ftee from nitrates before being putto butadiene service.
Peroxides and polyperoxides in butadiene are alsohazardous and these can be destroyed from the surfaceof equipment by treating with 20 percent NaOH atabout 50°C. In butadiene recommended maximumallowable concentration of dimer, oxygen and peroxideare following:
Dimer : 0.2 percent
Oxygen : 0.3 percent
Peroxides : 10 ppm
4.5 Corrosion Properties
Butadiene is non-corrosive.

Hard helmets should beused in plant areas to guard against accidental leaksand also from falling tools, etc. For further protectionrubber, PVC aprons and safety shoes should be worn.Self contained breathing apparatus (SCBA), positivepressure hose mask, air line masks are recommended.Industrial Canister type gas masks will afford protectionagainst concentration not exceeding 2 percent.
NOTE — Respirato~ protective equipment must be carefullymaintained, inspected, cleaned and sterilized at regular’intervalsand always before use by another person.
7 STORAGE, HANDLING, LABELLING ANDTRANSPORT
7.1 Storage
7.1.1 Mode
Being extremely flammable and potentially explosiveon contact with air, oxygen and oxidizing agents,butadiene should be stored in liquid form underpressure at ambient temperature away from potentialsource of ignition or sparks and oxidizing agents. Itshould be inhibited with 0.01 to 0.02 percent of paratertiary butyl catechol (PTBC). For pressure storage avessel in the form of sphere is most favoured.Refrigeration storage is also done. Usually it is storedat 10°C to minimize dimer formation. Threaded pipingshould be avoided. Cast iron parts or equipment shouldnot be used. Drainage should be provided. Theinhibitor content must be checked periodically. Thestorage should be free from air or oxygen. Storagevessel should not be made of copper, magnesium, silveror alkaline earth alloys.
Before filling the storage vessels with butadiene thetank and all lines should be made free from air, oxidesof nitrogen, phenols and oxidizing agents.
During unloading operation, the container, the tankfrom which it is being unloaded and truck chassisshould be electrically connected and grounded toprevent spark.
Cylinders of butadiene should be stored upright in acool, dry, well ventilated location, away from sourcesof heat, open flames and sparks. The storage areashould be segregated from supplies of oxygen, chlorineand other oxidizing chemicals and gases andcombustible materials. A cylinder should not besubjected to temperature above 55°C.

IS 14984:2001
7.1.2 Ventilation
Good ventilation is required in rooms or storage wherebutadiene is stored. Storage in pits, depressions andbasements should be avoided.
7.1.3 Flooring
Fire resistant flooring should be laid in storage areas.Adequate drainage should be provided to drain awaythe liquid from the storage tank and minimize fireexposure of the tanks. A suitably designed Dike isdesirable
7.1.4 Electrical Fittings
Explosion proof electrical fittings conforming togroup IIBofIS2148 should be used in storage areas.All metal surfaces with which butadiene come incontact must be grounded or bonded so that theresistance to ground does not exceed 7 ohms. Thiswill prevent static charges. Lighting protection deviceshould be installed to prevent fire from lighting.
7.2 Handling
Butadiene should be unloaded through a closed systemusing vapour return line and compressor or inert gaspressure. All precautions must be taken to guardagainst health and fire hazard whenever butadiene ishandled. Suppliers instructions should always befollowed and all caution markings be strictly adheredto. Leaks should not be present. If transfer is doneinto a tanker, the tankers’ design and constructionshould be as per BIS for butadiene. The lagging of thepipelines should be checked well.
7.3 Labelling
The following label, in addition to or combination withany label, warning required by statutes regulations,ordinance is recommended for butadiene.
Name of material : 1,3-BUTADIENE(INHIBITED)
Danger : Extremely flammable liquid andgas under pressure. Liquid causesfrost bums, may form explosiveperoxides on exposure to air.
Do not breathe vapour.
Do not get in eyes, or skin, or clothing,
Use with adequate ventilation.
Keep away from heat and open flame.
Do not drop a cylinder.
7.4 Transport
7.4.1 Butadiene is usually transported throughpipelines and tankers. Since butadiene is transportedat a low temperature to prevent polymerization, thetank should be insulated. Butadiene tankers should
—.
not be used for any other product. The tanker should ,
also follow UN Code 1010 for transportation of =1
dangerous goods. “~
7.4.2 Proper warning, a label and signs should bemarked on the tanker. The tanker must have a placard
y
,,.4
class label of “Flammable”. A slight pressure aboveL
atmosphere should be maintained inside the filledtanker out of contact with air or oxygen. Two fireextinguishers should be fixed on each tank lorry.
7.4.3 Only trained drivers should be employed fortransporting butadiene.
7.4.4 The storage, transportation and handling ofbutadiene should conform to the Gas Cylinder Rules,1981 and its storage, transportation and handling invessel should conform to the Static and MobilePressure Vessels ( Unjired) Rules, 1981 administeredby the chief controller of explosives.
8 SPILLAGE/LEAKAGE AND WASTEDISPOSAL
8.1 Spillage/Leakage
8.1.1 Regular inspection of equipment and vesselscontaining butadiene should be made to detect orprevent leaks. Soap solution may be used but nomatches or open flames should be used to check theleaks. If spillage or leakage develops, ignition sourcesshould be eliminated and people should be kept awaybecause butadiene in contact with air will formflammable/explosive mixtures. .,
8.1.2 To much exposure may cause dizziness, lethargy,eye irritation and if liquid, frost bite.
8.1.3 The area around the spillage should be wetteddown with large quantities of water and allow theliquid to dissipate. The spillage can be absorbed onsand and shoveled carefully to safe areas and destroyedby burning. Spillage can be diluted with PTBCdissolved in toluene before mixing with sand. Goodventilation should be there so that gas should bedissipated below its lower explosively limit. Sand andshovel should be readily available.
8.2 Waste Disposal
8.2.1 Solid waste will be usually polymeric materials(Popcorn polymer) with gaseous or liquid butadieneabsorbed sometimes.
8.2.2 Before collecting the waste from lines and servicetanks, all equipment should be depressurized and thegases are vented out safely below the explosive limitor to a burning flare. After the removal of the gasesthe polymeric wastes can be treated with 20 percentNaOH solution at 48-50”C to decompose/destroy theperoxide and polyperoxides, if any, are formed.
4
I
Otherwise, the waste could be removed under wetcondition and burnt into a pit/incinerator, adding smallquantities at intervals. Popcorn polymers areunsaturated in nature and tend to ignite when exposedto air. Hence it should be removed under wet conditionwith water.
9 FIRE PREVENTION AND FIRE FIGHTING
9.1 Fire Prevention
9.1.1 Explosion/tlame proof electrical equipmentshould be used in place where butadiene is handled.Static charge, flames, ignition sources, lights,oxidizing agents, copper, magnesium, silver, alkaliearth metal alloys should not be present wherebutadiene is handled. Sampling should not be doneduring lightning and hail storm.
9.1.2 All metal surfaces with which butadiene comesinto contact must be grounded so that resistance toground does not exceed 7 ohms.
9.2 Fire Fighting
Cool the butadiene container which is on fire withfine spray of water without putting out the flame tillthe valve supplying the gas is isolated. Cut offbutadiene supply to the fire before attempting toextinguished using COZ,dry chemical powder (DCP),foam and water fog. Attempt to cool the nearbyequipment and tanks which are handling and storingflammable liquids and gases. Do not use water jet.
9.3 Air Monitoring of the Work Place
Periodical air monitoring should be carried out toassess the exposure risk, and necessary controlmeasures should be implemented to maintain theambient concentration of butadiene below TLV.
10 TRAINING AND HEALTH MONITORING
10.1 Training
10.1.1 The trainer should be familiar with the contentsof the safety data sheet. Persons who handle butadieneshould be instructed carefully in the accepted methodof handling and be appraised of the use of protectiveequipment for safe handling.
10.1.2 During training stress should be laid onhazardous properties of butadiene due to fire andexplosions, so as to impart an indelible impression onthe persons who handle butadiene.
10.1.3 All workers should be familiar with the locationof safety showers, alarm boxes, emergency ventilationsystem, first aid boxes, fire extinguishers and hose lines,protective equipment, gas masks and artificialrespiration methods. They should be given training inthe methods of operation of the equipment mentioned.
1s 14954: ZUul
10.1.4 Each employee should be periodically givenrefresher training on safety measures associated withbutadiene.
10.2 HEALTH MONITORING
Pre-employment examination are required for personswho would be exposed to butadiene. In general,asthmatic persons and those suffering from acute orchronic diseases of the respiratory system should notbe exposed to butadiene vapours. A periodic healthexamination including chest x-ray should be per-formed on all employees exposed to butadiene. Athorough investigation should be made of any changesreferable to the respiratory system revealed by theexamination. Periodical examination should be doneannually. Proper records should be maintained so thatvariation if any, could be studied and remedies besuggested by the physician.
11 FIRST AID
11.1 Affected persons showing signs of excessivebutadiene inhalation should be removed at once fromthe contaminated area. If breathing has stopped,artificial respiration should be started immediately.All contaminated clothing and shoes should beremoved.
11.1.1 Eyes
Immediately flush eyes with plenty of water for at least15 minutes. hold eyelids apart while flushing to rinseentire surface of eye and lids with water. Get medicalattention.
11.1.2 Skin
In case of cold burn, immediately place affected areain warm water (41‘C) and keep at this temperatureuntil circulation returns. Get medical attention.
11.1.3 Ingestion
