Personal Protective Equipment

Proper Waste Management
Biological waste, including sharps, liquid cultures, contaminate disposable materials, and animal carcasses, mutt be handled in a way that prevents exposure during storage, transport, and disposal. The first step is segregation: different waste streams require different treatment methods. Sharps (needles, broken glass, pipette tips) are placed puncture- resistant, resistent, resive-proof concerers clearly marked with biohazard symbol. -sharpsolid (ests) (e.g.g.cule, cule, cule, beench papech) ited difter ted diphabt, bagin, bagion, bagich.

All waste conteners mutt be labeled with the date, waste type, and generator information. A waste log tracking the volume andd treatment methods helps demonstrante compleance during inspections andd audits. Laboratorios should also have a continency plan for waste spils during transport within the facility, including spill kits and a clear notification chain.
Emergency Preparedness andSpill Response
Nie matter how strong the preventive measures, consuments can happen. A well-prepared laboratoria has written emergency procedures for biological spils, personal exposures, and equipment malfunctions.
