Laboratory personnel working with infectious agents are
subject to laboratory-acquired infections as a result of
accident or unrecognized incidents. The degree of hazard
depends upon the virulence of the biological agent concerned
and host resistance. Laboratory acquired infections occur
when microorganisms are inadvertently ingested, inhaled, or
introduced into the tissues. Laboratory personnel are
relatively safe when working with Haemophilus influenza and
streptococcus pneumoniae; however, person who work with
aerosolized Neisseria meningitides are at increased risk of
acquiring a meningococcal infection. The primary laboratory
hazard associated with enteric pathogen such as shigella,
vibrio or Salmonella is accidental ingestion. Biosafety level 2
(BSL-2) practices are suitable for work involving these agents
that present a moderate potential hazard to personnel and
the environment. The following requirements have been
established for laboratories working in BSL-2 facilities.
• Laboratory personnel must receive specific training
in handling pathogenic agents and be directed by
competent scientists.
• Access to the laboratory must be limited when work
is being conducted.
• Extreme precautions must be taken with
contaminated sharp items.
• Certain procedures involving the creation of
infectious aerosols or slashes must be conduct personnel who are wearing protective clothing and
equipment.
