U.S. DEPARTMENT OF LABOR BUREAU OF LABOR STANDARDS WASHINGTON ' 20210 January 5, 1968 In Reply Refer to: 3-202 Executive Committee Chemical Section National Safety Council Gentlemen: It is the intention of the Office of Occupational Safety in the near future to require that businesses subject to our regulations ascertain the hazards to their personnel of material used in their establishments. Since it is rather obvious that the source of such information will be the manufacturers of the materials, it seems appropriate to ask the members of the Executive Committee, Chemical Section, for their reactions to the proposal. The enclosed is a suggested form of data sheet and a suggested form of label for hazard identification. It is not our intention to make either one mandatory although it will be mandatory to have available the type of information indicated on the data sheet. We hope by this means, or something similar, to get it available on a single sheet. The basis for the hazard ratings shown on both the data sheet and the label are shown on the back of the data sheet. It should be kept in mind that these are intended primarily to concern acute hazards, not effects of chronic exposures and that they are Intended to provide essential information for strictly non-technical people. We will appreciate any comments which you may care to make. Sincerely yours, Enclosure /s/ F. A. Van Atta F. A.

Reactivity Grades Grade 0 - No appreciable self-reaction and chemically unreactive but may be attacked by Grade 4 materials. Grade 1 - Midly reactive materials, reacting mostly with Grade 4 or capable of self-reaction at low rates and with low heat evolution. Grade 2 - Reactive with members of Grades J and 4 but not with Grades 0 and 1 or self-reactive If con taminated by on Initiator, The self-reaction may be hazardous. Grade 3 - Are apt to react with each other with members of Grades 2 and 4, or undergo a hazardous selfreaction ard require special handling to Insure safety in transportation. Grade 4 - Chemtcals which react with each other and with all other grades. Including Grade 0 or which undergo self-oxidations with explosions or detona tions. Skin Grades Grade 0 Grade ( Grade 2 - No appreciable damage to the skin. - Chemicals which, If spilled on the clothing and permitted to remain, wiII cause no more than smarting and reddening of the skin. - Chemicals which wilt cause smarting and firstdegree burns with short skin exposure and seconddegree burns with long skin exposure. CMA 060129 2 Grade 3 Grado 4 - Moderately severe skin irri+an+s causing pain and second-degree burns after relatively short contact. - Severe skin irritants causing second and thirddegree burns on short contact and very injurious to the eyes. Toxic Grades Grade 0 Grade 1 Grade 2 Grade 3 6rad& 4 - No likelihood of producing injury. - Most chemicals having threshold limits above 500 ppm. - Chemicals having threshold limits of 100 to 500 ppm. - Moderately hazardous chemicals mostly with threshold limits between 10 and 100 ppm. - Severely hc2are(cus chemicals having threshold limits below ID ppm.
