I ndian St an.dardCODE OF S FETY FOR

METHYL ETHYL KETONE

i 0 FOREWORD0.1 This Indian Standard was ado ted by the Bureau of Indian StandardsonY17 August 1987, after the dra t finalized by the Chemical HazardsSectional Committee had been approved by the Chemical DivisionCouncil. r0.2 Methyl ethyl ketone is used as solvent for variety of resinousmaterials, such as vinyl films, glyptal resins, adhesives, printing inks,lacquers, lubricant oil, refining and cleaning fluids. It is used as acatalyst carrier, ia vegetable oil extraction processes, in preparationof flavours, antioxidants, perfumes, in the manufacture of n,amyl ketoneand methyl ethyl ketone peroxides.0.3 In the preparation of this code, considerable assistance has beenderived from the following publications.

a) Dangerous Propertiea of Industrial Materials, third Edition,by N. Irving Sax, Reinhold Publishing Corporation, 1957.b Material Safety Data Sheet ( No. 303 ). Published by Mate-rials Information Service, General Electric Company USA1979.c) Manual for Handing and Disposal \vith Toxicity and HazardData. Published by International Technical InformationInstitute, Japan. 1981.

1. SCOPE1.1 This standard describes properties of methyl ethyl ketone, thenature of hazards associated with it and essential information onstorage, handling, pack& labelling, disposal of waste, cleaning ofspillages, training uf personnel, personal protective equipment andfirst aid.

4.2 Route of Entry - Inhalation, absorb i>a through skin.4.3 Health Effects - M:tAyl ethyl ketone is neither highly toxic nor itexhibits cumulative toxological prnptrties. It is slightly more toxic thanacetone. Inhalation of vapours over prolonged periods may irritate themucou< membrane and cause nausea and eventually loss of conscioussess.4.3 1 Eyes - Eye contact causes ir itation and burning sensationof the eyelids.

4.3.2 Ingestion - Ingestion causes irritation to the digestive tract.Larger quantities ( 25 g ) can cause narcosis.4.3.3 Skin Contac t It can be absorbed through skin which defatsand irritates the skin. When methyl ethyl ketone is mixed with normalhexane, it causes synergistics effect.4.3.4 M edi cal M oni r or ng - Provide regular medical monitoring,including blodd cell count of those exposed to tnls material in the workplace.

7. SPILLAGE/LEAKAGE AND WASTE DISPOSAL *7.1 Spills and Leakages

7.1.1 If spills and leaks occur, shut off all sources of ignition orremove them from the area as early as possible. Only persons provtdedwith adequate personal protective-equipment should remain in the area.7.1.2 Spills, unless very large, should be absorbed on paper or otherabsorbent material.7.1.3 Scrape up with a non-sparking scoop and place in a coveredmetal container for disposal. Those involved in clean up should useprotective equipment. Dispose of the scrap by burning in a remoteopen pit or depositing in a sanitary land-fill. Do not dump the materialdown the sewer.7.1.4 Material from a leaky container should be carefully transferredto another suitable container. Durmg such transfer, all sources ofignition must be kept away from the area.7.1.5 In the event of a leak in a tank car which cannot be readilyrepaired by simple adjustments or ttghtening of the fittings, the suppliershould be telephoned or wired inmediately for instructions. The areaaround the tanker sllouid be evacuated and only properly p,otectedpersonnel should be allowed to enter the area.7.1.6 Clothings wet with methyl ethyl ketone should be removedimmediately and body washed with soap and water. The clothingshould not be used again until thoroughly cleaned and dry. .

7.2 Waste Disposal7.2.1 All relevant regulations of local and State Authorities for preven.tion and control of pollution should be observed.7.2.2 Water contaminated with methyl ethyl ketone should be sentfor eflluent tr,&tment before discharging to the river or creek.7.2.3 Best way to dispose of the methyl ethyl ketone waste is byincineration in a furnxe.
