LABORATORY SAFETY Flashcards
source of danger which can be defined as “a condition or situation that exists in the work environment that could result in physical harm, injury and/ or damage”.
Hazards
“the likelihood of a hazard causing harm”
Risks
“the degree of likelihood that harm will be caused”
Risks
relates to exposure to the danger
Risks
What are the 6 hazards?
- Biological
- Physical
- Ergonomic
- Chemical
- Radiation
- Psychological
Managing risk means _________________

Managing risk means ______________
Managing risk is all about __________opportunity and ____________ threats
forward thinking
responsible thinking
balanced thinking
maximizing
minimizing
This process provides a framework to facilitate more effective decision making
risk management
Identifying and understanding the risk points
Analyzing risks
Assess based on probability and severity/impact
Evaluating risks
Pick the highest risk and decide how to mitigate them
Controlling risks
Check if the mitigation is effective
Monitoring risks
Systematic approach to identify hazards, evaluate risk, and incorporate appropriate measures to manage and mitigate risk for any work process or activity.
Risk assessment
minimum infection prevention practices that apply to all patient care, regardless of suspected or confirmed infection status of the patient, in any setting where healthcare is delivered.
Standard Precautions
How often must the risk assessment be reviewed?
- At least once every 3 years;
- After an accident;
- When there is significant change in work processes, introduction of new machinery or chemicals;
- Information on safety technology or requirement made known
Application of safety and containment measures to minimize or prevent exposure from infectious agents to the person handling it in the lab, building occupants and the environment
Biosafety
This prevents accidental release
Biosafety
“Product worker from the bad bugs”
Biosafety
This is an institutional measures designed to prevent the loss, misuse, diversion, intentional/deliberate release of pathogens and toxins.
Biosecurity
This prevents deliberate release
Biosecurity
“Protects the bugs from bad workers”
Biosecurity
This is a combination of laboratory practices and procedures, safety equipment (primary barriers) and facilities (secondary barriers)
Biosafety level
developing procedures to ensure the work conducted in a way that minimizes the hazard by reducing the duration, frequency or intensity.
Administrative controls
- developing or changing policies (SOP, GMT, RM)
- implementing or improving training and education
- enhancing work practices
- ensuring adequate rest breaks
- limiting access to hazardous areas
Administrative controls
developing procedures to ensure the work
conducted in a way that minimizes the
hazard by reducing the duration, frequency or
intensity
Engineering Controls
Ventilation
Isolation rooms/ negative pressure rooms
biosafety cabinet
lab design
Engineering controls
How is biosecurity promoted?
Physical security
personnel security
Pathogen security
Information security
Transport security
Access control, intrusion detection, alarm assessment
Physical security
Bag check, periodic investigations, personnel reliability programme
Personnel security
Detailed inventory, acceptance and collection records, inactivation and disposal records
Pathogen security
Confidentiality, passwords, back ups, protocols in record keeping.
Information security
3-way packaging system
Chain of custody, International Air
Transport Authority
(IATA) certified personnel
Transport security
Hierarchy of Controls
- Elimination
- Substitution
- Engineering controls
- Administrative controls
- PPE
This refers to Physically remove the hazard.
Elimination
This refers to replacing the hazard
SubstitutionT
this refers to isolating the people from the hazard
Engineering controls
This refers to changing the way people work
Administrative controls
This refers to protecting the worker with PPE.
PPE
It is a written program stating the policies, procedures, and responsibilities that protect workers from the health hazards associated with the hazardous chemicals used in that particular workplace. Must be reviewed annually.
