Bfi| jq ' CM This rating system is intended to reflect possible health hazards resulting from a single, short-term or accidental exposuro to the compound. 0. NONE Materials that result in injury only under unusual conditions or by overwhelming dosago. 1. SLIGHT Short term exposure may result in minor injury that i3 reversible. 2. MODERATE Short term exposure may result in minor temporary or permanent injury; may possibly result in major injury. 3. HIGH Short term exposure may result in major temporary or permanent injury. May threaten life. 4. EXTREME Short term exposure may result In major permanent injury or death. 0. NONE Material will not burn in air. 1. MINOR Matoriai must be preheated before ignition can occur. 2. MODERATE Material must be moderately heated before ignition will occur. Includes solids that give off flammable vapors. 3. SEVERE Material can be ignited under almost all normal temperature conditions. 4. EXTREME Very flammable gases, very volatile flammable liquids, and materials that in form of dusts or mists can form ex plosive mixtures with air. A. Store in cabinet or room flammable liquids. 8. Storage room should be w C. Strong oxidizing agent. Oo materials, e g. Ilammabies. bustible materials D. Flammable material Separ ces of ignition. E. Combustible material. Se- sources of igntion. F.

Absorbs carbon dioxide U. Separate from oxidizing V. Pyrophoric'Store under toluene or keroseno. W. Pyrcphoric/Always keep X. Strong reducing agent. 0. NONE Normally stable even under exposure to lira: not reactive with water. 1. MINOR Unstable at high temperatures and pressure or may react with water with seme release of energy, but not violently. 2. MODERATE Normally unstable and undergo violent chemical change but will not detonate; may form explosive mixtures w.th water. 3. SEVERS Explosive il 3trcngly initiated, heated or water ad ded. 4.
