OSMT- Laboratory safety with comprehensive questions and
answers
what are the 4 main categories of hazards in the laboratory✔️✔️1) biological
2) chemical
3) physical
4) psychological
what type of approach should you have when identifying hazards, assessing the risk and
determining control measures
a) first aid approche
b) systematic approach
c) knowledgeable approach
d) ladder approach✔️✔️b) systematic approach- having each job or task reviewed to identify the
hazards of all types
what is the assessment of risk based upon✔️✔️based on what the task is, what equipment is used
and where the tasks are being done
what are the level of risks calculated by✔️✔️number of worker exposed to hazard, how often they
are exposed and the severity and probability
are hazards the same as risks?✔️✔️no
what are the 3 ways to identify hazard controls✔️✔️1) engineering controls
2) administrative controls
3) personal controls
,what are engineering controls
-name some examples✔️✔️actions, items or equipment designed to reduce harmful exposure
examples- isolation of the hazard from the worker ( glove boxes, enclosed tube systems in
automated equipment)
-ventilation controls (chemical fume hoods, BSC)
-guarding between the worker and moving parts- pumps, centrifuges)
what are administrative controls✔️✔️actions taken by the administrators of an organization to
reduce employee exposure to hazards
eg : -training for new workers
-substitutions for hazards an processes
-reduce prolong exposure- schedule change
-inspections
-emergency plans
-occupational health programs
-pre work checklists
what are some personal controls✔️✔️refers to the use of PPE for lab work
ex: gloves
-gowns
-lab coats
eye protection
-respirators
, -proper footwear
what are some emergency events that can happen in the lab✔️✔️-explosion
-chemical spill
-biological spill
-violence
-power failures
-information system failures
-severe weather
-floods
-ventilation failures
-bomb threats
-infectious disease exposure
what are biological hazards✔️✔️-the potential for a variety of lab-acquired infections
what are some examples of biological hazards✔️✔️-needle puncture
-injury with broken glass, sharp object
-contact from biological skills, sprays , aerosols, mucous membrane or broken skin
-aspiration through pipettes
-animal bites or scratches
which administration is responsible for then enforcement of the human pathogen and toxins act
and regulation✔️✔️minister of health - the purpose of this legislation is to establish a safety and
security regime to protect the health and safety of the public against the risk posed by humans
and animal pathogens and toxins
engineer controls for biological hazards✔️✔️-eliminate or substitute exposure to risk
-immunization programs
