Biological Containment
Containment types
Primary containment
It is the first container direct contact
with
bio hazardous material
as well as protection of personnel
immediate laboratory environment
from exposure to infectious agents
Secondary containment
It is the protection of environment
external to the laboratory from
exposure to infectious materials .
Microbial containment
Microbial containments include
viruses;fungi;parasites and bacterial
agents .
Following the examples are :
Viral examples
Conti.
Hepatitis B has been one of the most
frequently occurring laboratoryassociated infections, and laboratory
workers are recognized as a high-risk
group for acquiring such infections
Fungal examples
Occupational Infections:
Three groups are at greater risk of
laboratory acquired infections:
Microbiologists, Veterinarians and
Pathologists
Pulmonary infections have occurred
by the inhalation of conidia from
mold form cultures along with
pneumonia and osteolytic lesion
case.
Histoplasma capsulatum
Occupational infections:
Pulmonary infections have resulted from
handling mold form cultures
Local infection has resulted from skin puncture
during autopsy of an infected human, from
accidental needle inoculation of a viable culture
and from spray from a needle into the eye
Collecting and processing soil samples from
endemic areas has caused pulmonary
infections in laboratory workers
Bacterial examples
Bacillus anthracis
LABORATORY SAFETY AND CONTAINMENT
RECOMMENDATIONS:
The primary hazard to laboratory personnel are:
direct and indirect contact of broken skin with
cultures and contaminated laboratory surfaces,
accidental parenteral inoculation, and rarely
exposure to infectious aerosols.
Efforts should be made to avoid aerosols. In
addition all centrifugation should be done using
aerosols tight rotors.
