VESE IS <br />Contingency Plan <br />Section 5 — Effective Date Supersedes Page <br />Pre-Emergency Planning 9120/2021 New 5-9 <br />d. Oxidizers: <br />Oxidizers yield oxygen readily to stimulate burning of combustible <br />materials. If spilled, they should be kept from contacting flammable <br />liquids and other combustible materials. Oxidizers contain available <br />oxygen and when heated or shocked, can decompose with explosive <br />force. If any of these materials are involved in a fire or a large spill, <br />personnel should be evacuated from the scene. <br />Examples include: <br />Ammonium nitrate <br />Calcium hypochlorite <br />Hydrogen peroxide <br />Potassium permanganate <br />Sodium nitrate <br />Sodium nitrite <br />Some oxidizers, such as hydrogen peroxide, will eventually decompose <br />becoming, essentially, harmless compounds. Others do not, and <br />though they may look inert and harmless, may still be dangerous if not <br />cleaned-up and handled properly. <br />In the event of a spill, try and contain the material with a dike made of <br />sand or inert sorbent to keep the oxidizer from coming into contact with <br />any combustible material. After the oxidizer has finished decomposing, <br />it may be collected and put into recovery drums. <br />Personnel coming into contact with an oxidizing material should be <br />flushed with massive amounts of water and obtain medical <br />assistance as soon as possible.
