Additional Instructions: • In case of skin contact Go to the nearest emergency shower if contaminated. Yell for assistance and rinse for 15 minutes, removing all articles of clothing to ensure contaminate is completely removed. Follow up at Acute Care/Employee Health as appropriate. In case of eye contact Go to the nearest emergency eyewash. Yell for assistance and rinse for 15 minutes. Follow up at Acute Care/Employee Health. Small Spill If a small spill occurs inside a fume hood or near other local exhaust ventilation, lab personnel should be able to safely clean it up by following standard spill clean-up procedures:•Alert people in immediate area of spill • Increase ventilation in area of spill (open fume hood sashes) • Wear personal protective equipment, including utility grade nitrile gloves • If available, cover spill with acid/base neutralizer • If neutralizer is not available, confine spill to small area with adsorbent material (pads, vermiculite) • Collect residue,place in container, label container, and dispose of as hazardous waste• Clean spill area with soap and water Larger Spill • Call EHS for emergency assistance • Evacuate the spill area • Post someone or mark-off the hazardous area with tape and warning signs to keep other people from entering • Stay nearby until emergency personnel arrive and provide them with information on the chemicals involved 4. Waste (Procedures, Storage, and Disposal): Hazardous Waste must be properly labeled and may be stored in a designated Satellite Accumulation area for up to 9 months. One container per waste stream is permitted at a time. When the container becomes full or reaches its 9 month accumulation limit,request a waste disposal pickup by emailing Risk Management riskmana eg mentkpacific.edu. Additional Instructions: Acids and Bases must be neutralized before discarding. Hazard-free salt solutions from acid-base neutralization may be disposed of down the drain. Common examples include the waste of hydrochloric acid or sulfuric acid neutralized by sodium hydroxide.Hazardous salt solutions, e.g.heavy metal salt solutions such as Ni, Cr,Pb, etc.,MUST be collected in the aqueous waste container in the laboratory. IF NOT SURE,ASK SUPERVISOR HOW TO DISPOSE. 5. Details of Process Any waste in the laboratory that has been identified as acidic(pH<7)or basic (pH>7)must be neutralized to pH 7. The solution shall be neutralized in a wide-neck container(e.g. beaker)that is not filled more than 50%of its total volume. During neutralization, add only small quantities of acid/base (as appropriate)to the solution to be neutralized. Stir the solution continuously(can be manually with glass rod or mechanically with a magnetic stirring plate or slow shaker). In case concentrated acids or bases have to be neutralized,monitor the temperature of the solution to be neutralized and provide adequate cooling(ice bath) if needed. This prevents overheating,boiling and overflowing of the solution out of the container. Progress of neutralization should be monitored with small samples applied to general-purpose pH-paper until green H 7). 6. Training All personnel are required to complete all General Safety and Lab Safety training requirements and any additional training sessions specific to equipment and chemicals in the work area. PI's or Lab supervisors shall work with the EH&S and the Learning and Development Departments to ensure all necessary trainings are selected and completed by lab personnel. Additional Training Required: All personnel are trained to safely use concentrated acids and bases and to properly neutralize these solutions.
