HAZARD ANALYSIS

PATHOGEIC MATERIAL - The term “pathogenic” simply means that there is the potential for live disease-causing organisms
to be present. The pathogens isolated in this facility are spread through food ingestion. Personnel will not have food or
drink in any laboratory area. Regular hand washing is required as a preventative measure. Any spills of non-
decontaminated garbage or jugs should be reported immediately to a Director. If the Laboratory Director is not accessible,
consult the Micro. Lab Lead or Quality Systems Analyst (QSA) for containment and clean-up procedures.
BIOHAZARD TRASH
Hazard - All garbage in biohazard trash bags is considered pathogenic until it is autoclaved.
Preventative Measure- Do not handle biohazard trash. Disposable gloves must be worn when handling non-autoclaved
biohazard trash. Any spills of garbage should be reported immediately to the QSA or Laboratory Director. Alternatively, a
Microbiologist may contain and clean-up spills.
POSITIVE CONTROLS
Hazard - Improper handling of live positive control organisms resulting in illness or contamination of the worker or work
environment.
Preventative Measure - Aseptic technique must be employed. Disposable gloves will be worn when handling positive
controls. Hands will be washed after each exposure and 10% bleach or 70% ethanol solutions will be used to clean work
surfaces.
AUTOCLAVES
Hazard - Steam burns to arms from exhausting autoclaves
Preventative Measure - All personnel will wear protective gloves that come to at least the elbow on both arms.
Hazard - Steam burns to face from exhausting autoclaves
Preventative Measure - The autoclave door will be opened slowly and approximately only 1-2” to allow slow steam escape.
Hazard - Freshly autoclaved media or trash can release hot liquid and steam from without warning.
Preventative Measure- The autoclave door will be opened slowly and approximately only 1-2” to allow slow steam escape
and all personnel will wear protective gloves that come to at least the elbow on both arms, face shield, and apron. Allow
items to cool for a minimum of 10 minutes on autoclave rack. Wear all PPE when handling freshly autoclaved media, pre-
enrichment containers, or trash. Ensure that all containers of media with caps and any enrichment jug containers with lids
have lids that are loose and secured before placing into the autoclave. Do not disturb containers that have become
deformed in the autoclave, due to pressure build up until they are completely cool.

glass” boxes located in the pathogen and chemistry labs. Protective gloves will be worn when washing glassware.

Preventative Measure- Open the dishwasher slowly and wait for the steam to escape.
WET AREAS ON FLOORS
Hazard - The floors of the autoclave and jug-wash rooms are often wet due to jug wash activities and water leaks from the
autoclaves. When these floors become wet, the tile becomes very slippery and is a potential slip hazard to personnel. The
area surrounding the dishwasher in the chemistry lab can also become very wet at times. The worker should be careful in
this area especially when carrying tubs of glassware and other items.
Preventative Measure- The worker should be careful in all areas and look for any water on the floors. Mopped areas will be
marked with a wet floor sign. The worker should be careful in this area especially when carrying tubs of glassware and
other items.
