Chemical Procedures

• Hazardous Waste Management- “Hazardous Chemical Waste Management, 5th

hazardous waste

to fresh air, remove contaminated clothing and flush contaminated skin and eyes with water for 15 min

- call 911 if anyone has been injured

• Confine- close door and isolate the area

• Report- call 911- DEHS: 6-6002 - DEHS will clean up

• Secure- post signs and warning tapes

Autoclaving Biological Waste

• All disposable lab ware, except Pasteur pipettes, contaminated with potentially biohazardous materials.

• Note: gloves, regardless of contaminated or not, and paper towels used for work surface or equipment decontamination must be disposed of in a clear autoclave bag or red biohazard bag.

• Culture plates • Culture media

DO NOT overflow trash, fill it up to ¾ full.

• All Pasteur pipettes, needles and syringes, broken glass, slides and cover slips, should be placed in sharps containers for pick up. Do not autoclave.

• Liquid wastes can be decontaminated with one part bleach to ten parts liquid for 30 minutes and then it can go down the drain.

• Do not add bleach to materials that may contain ammonia or strong acids as dangerous chlorine gas may be produced.

• As an alternative to autoclaving, contaminated non-liquid materials can be placed in a red Biohazard bag and be collected as Biohazard waste.

Red bag disposal costs the University 10X more than disposal of autoclaved waste.

Decontamination• Work surfaces must be decontaminated with a suitable

disinfectant at the end of each day and after any spill of potentially dangerous material.

• Contaminated or infectious liquid or solid materials must be decontaminated before disposal or reuse.

Decontaminate by autoclaving all biologically contaminated materials before washing, reuse or disposal.
