Chemicals must be disposed of using environmentally safe procedures according to your local, state and federal regulations. Place used chemicals in waste containers designed and labeled for that purpose. Label the waste container with appropriate chemical information. Contact the school’s facility department for appropriate disposal instructions. Use only certified and approved chemical waste contractors. Minor Chemical Spill Clean up only minor chemical spills. Large spills require evacuation and the immediate contact of your local fire department’s hazmat team. Avoid breathing vapors. If someone is splashed with a chemical, use an eyewash station or emergency shower to immediately flush the affected area with copious amounts of water for at least 15 minutes. Seek medical attention as required. Wear safety goggles, gloves and long-sleeve lab coat during cleanup. Confine the spill to a small area. Use absorbent material to soak up spilled materials. Dispose of any waste according to your local, state and federal regulations. Rinse the spill area with water. Acid/Base Spill For a minor acid/base spill not directly on human skin, do the following: Avoid breathi ng vapors. Wear safety goggles, gloves and long-sleeve lab coat during cleanup. Neutralize acid spills with powdered sodium hydrogen carbonate (sodium bicarbonate/baking soda), or base spills with vinegar (5% acetic acid solution) or with sodium hydrogen sulfate. Spread inert absorbents to soak up the neutralized chemical. Sweep up and dispose the collected waste according to your local, state and federal regulations. HCl If splashed with chemicals, use eyewash immediately. Chemical Spills A fully-stocked spill clean-up kit for small spills should be easily accessible with the following suggested supplies: Neutralizing agents for acid spills (sodium hydrogen carbonate/baking soda) Neutralizing agents for alkali spills (sodium hydrogen sulfate/vinegar) Pick-up equipment such as brush, broom, pail, dust pan Personal protective equipment Inert absorbents such as sand or cat litter Cat Litter
