Biosafety Levels

Biosafety Level 2

Safety Precautions

  • lab has self closing doors
  • sink and eyewash are available

Lab Equipment

  • appropriate personal protective equipment
  • eye protection
  • face shields
  • biological safety cabinet
  • autoclave for proper disposals

Microbes

  • staphylococcus aureus
  • HIV
  • S. typhi
  • Hepatitis B and C

Lab Practices

  • access to the lab is restricted when work is being conducted
  • Each level has specific controls for containment of microbes and biological agents. The levels consider infectivity, severity of disease, transmissibilty, and nature of work conducted.

Description

  • microbes pose moderate haszards to the environment
  • microbes are indigenous and include diseases of varying severity

Biosafety Level 1

Safety Precautions

  • available sink
  • doors to separtae the working space with rest of the facility

Lab Equipment (personal protective equipment)

  • lab coats
  • gloves
  • eye protection

Lab Practices

  • standard microbiological practices
  • work can be performed on an open lab

Mircobe

  • nonpathogenic strain of E. coli
  • S. cerevesiae
  • N. gruberi

Description

  • microbes designated to BSL-1 are not known to consistently cause disease in healthy adults and present minimal potential hazard to the environment

Biosafety Level 3

Biosafety Level 4

Lab Practices

  • changing clothing before entering
  • shower upon entering
  • decontaminate before exiting
  • Persons entering be advised of hazards

Safety Precautions

  • hands-free sink and eyewash near exit
  • exhaust air cannot be recirculated
  • entrance of lab is two sets of self closing and locking doors

Lab Equipment

  • appropriate personal protective equipment
  • respirators
  • all microbes must be performed within and appropriate BSC

Lab Equipment

  • work containing microbes must be within an appropriate Class lll BSC
  • full body, air supplied, positive pressure suit

Microbes

  • ebola
  • marbug
  • Lassa virus
  • Argentine hemorrhagic fever

Lab Practices

  • laboratorians are under medical surveillance
  • receive immunizations
  • access to lab is restricted and controlled at all times

Description

  • microbes may be either indigenous or exotic
  • can cause lethal diseases through respiratory transmission
  • respiratory transimission is the inhalation route of exposure

Safety Precautions

  • the lab is in a separate building or isolated restricted zone of building
  • lab has dedicated supply and exhaust air
  • vacuum lines
  • decontamination systems
  • Persons entering be advised of hazards
  • Biosafety manual be adopted
  • Lab routinely decontaminated
  • Infectious materials placed in leak proof container
  • Medical surveillance
  • Daily inspections

Description

  • microbes are exotic and dangerous
  • high risk of aerosol-transmitted infections
  • infections caused by infections are fatal without treatment or vaccines

Microbes

  • mycobacterium tuberculosis
  • SARS
  • west nile
