c. Equipment Hazards and Risk: <br /> Due to the risk of container leakage, always place the containers in secondary containment and inspect the <br /> waste containers weekly to ensure they are in good condition. <br /> 2. Hazard Control <br /> a. Chemical Selection and Purchasing: <br /> Chemical usage and purchasing shall be planned such that: <br /> • The safest chemical to accomplish the job shall be chosen <br /> • Open bottles and those closest to expiration shall be chosen over opening new bottles <br /> • The surplus inventory will be checked before making any purchases <br /> • Purchases shall be limited to the amount needed that can be used within one year. <br /> Additional Instructions: NA <br /> b. Engineering Controls: <br /> When hazards cannot be eliminated or reduced through substitution, determine if additional engineering controls <br /> can be used to reduce risks(fume hoods, flammable cabinets, limited access, etc.). <br /> Additional Instructions: All concentrated acids and bases are used in fume hoods. The shield on the hood <br /> will also offer additional splash protection. <br /> c. Administrative and Work Practice Controls: <br /> When hazards cannot be effectively controlled through engineering,determine if additional administrative and <br /> work practice controls can be used to reduce risks(procedures, chemical segregation, etc.). <br /> Additional Instructions: Before experiments, carefully vet the amount of chemicals needed. Only limited <br /> amounts of concentrated acids and bases should be acquired from the Stockroom to decrease the amount of <br /> acid/base waste in the lab. <br /> d. Personal Protective Equipment PPE : Other PPE Required: <br /> ❑ Chemical splash goggles ❑ Blast shield <br /> E E E E ❑ Chemical-impervious gloves ❑ Fire resistant gloves <br /> Long Pants Lab Coat Gloves Safety <br /> Glasses ❑ Fire resistant lab coat <br /> (S: <br /> Other(please describe <br /> El L1® ® Use Nitrile gloves, lab coat/apron, safety glasses, or goggles when <br /> ® <br /> No Open Face Shield Respirator handling hazardous waste. <br /> Toed Shoes <br /> e. Storage and Transportation: <br /> When storing chemicals,utilize the proper equipment for the hazard of the chemical. i.e., flammable cabinet, <br /> explosion proof refrigerators, corrosive cabinets, acid cabinets, etc. Moving hazardous waste or chemicals <br /> between rooms or buildings with quantities greater than 500 mL shall be carried in a chemical-resistant tote that <br /> offers secondary containment and impact protection. <br /> Additional Instructions: Store hazardous waste in the dedicated Satellite Accumulation area within <br /> secondary containment. In 9 months or when the container becomes full, contact Risk Management @ <br /> riskmanagement@pacific.edu. All Acids are stored in the acid cabinet under the fume hood in secondary <br />
