Safe Work Practices (cont’d)

No shorts sandals etc No shorts, sandals, etc. “Universal Precautions” with

human bloodhuman blood No food, drinks, etc. No mouth pipetting Work carefully, deliberately



Use needles, syringes only if necessary

Decontaminate work surfaces, hands Report accidents Cuts, needlesticks, scrapes, , p Contamination of broken skin Splash of infectious materialp Incidents and near accidents

Containment Level

Minimum requirements for safe handling (4 levels)handling (4 levels) Operational practices

Safe work practices Engineering, technical, physical:

Location & access Surface finishes & casework HVAC Containment perimeter (windows, autoclave

location, etc.) Services (water drains gas electricity Services (water, drains, gas, electricity,

equipment)


Containment Level 1

No special design features No special design features Biological safety cabinet not required, may be

used for sterilityused for sterility Work may be done on open benchtop

Good aseptic/microbiological technique Good aseptic/microbiological technique


Containment Level 2

Additional physical requirements, e.g. Limited access, signage, lockable doors Resistant, non-absorptive surfaces (for disinfection)

Containment of aerosols: Biological safety cabinets Centrifuges with sealed rotors or safety cups

Minimize environmental contamination: Handwashing sinks Decontamination facilities (autoclaves)


Containment Levels 3 and 4 Level 3 Respiratory protection Respiratory protection HEPA filtration of lab exhaust Strictly controlled access Strictly controlled access

Level 4 Level 4 Isolated facility with sealed perimeter Positive pressure suits or Class 3 BSC Positive pressure suits or Class 3 BSC Effluent sterilization system
