Biological Hazards

Remains
Following completion of autopsy, all fluid collections must be absorbed by sponge and the dead bodies must be sutured in the best way possible to avoid cosmetic defects. The body must first be washed with detergent solution then antiseptic solution (household bleach 1:10). The body should then be rinsed with water and placed in a disposable leak-proof plastic body bag. In case the dead body is assumed to be infectious, a biohazard label must be pasted for safety of everyone handling the body before the last rites are performed. This should be mentioned in the death certificate as well. Fluid accumulations should be carefully removed by aspiration or blotting.

Bone dust and aerosols
Aerosols are commonly formed while sawing the bones; this can be reduced by moistening the bone before sawing. Besides that, systems like HEPA (high efficiency particulate air filtering) vacuum the dust and prevent it from being released.

Soft tissues extracted for analysis
The fixation of tissue for histopathological analysis require at least 10 time the volume of 10% formalin (containing 3.7% formaldehyde) than the tissue volume. Mycobacterium are not killed by this fixation and require 10% formalin in 50% ethyl alcohol. The time required also varies depending on the volume of tissue.

Management of waste and Human Tissue collected for analysis
Any tissue to be stored for analysis should be kept in a sterile, wide mouthed and air tight container. The contained must be sealed adequately and transported in an opaque plastic bag. Disposable waste must be double bagged, secured and stored in metal or plastic canisters/containers. Any spills must be cleaned with disposable towels and contaminated area cleaned with detergent followed by household bleach (1:10). Finally, the decontaminated area should be wiped dry.

After removing gloves, one should wash his or her hands with soap and water and/or immediately following contamination.
