Introduction

• Lab workers play a crucial role in preventing the occurrence of infectious and non-infectious diseases.

• Everyone working in labs should have an understanding of why they must work safely.

• Working in a safe and sound workplace could contribute in the avoidance of accidents and disaster.

• Health at work and healthy work environments are among the most valuable assets of individuals, labs and countries.

Laboratory Health & Safety Training

OBJECTIVES: To enhance lab staff and management’s awareness and

understanding on the basic knowledge of health and safety in the laboratory

To guide participants in conducting an actual risk assessment

To assist participants in establishing measures to mitigate/control the risks found in the laboratory

To provide guidance on development of laboratory health and safety guidelines.

EXPECTED OUTCOMES:

Development of health and safety guidelines / policy

77

Laboratory Health & Safety Training

• 3 day training, lecture and practice

• Dr. Gliceria Derrota - Trainer

• 8 training modules:

1. Introduction of Health and Safety 5. Biological Risk Assessment

2. Defining Hazard and Risk 6. Risk Matrix (Evaluation of Risk)

3. Recognition of Hazards (biological, physical, chemical, mechanical and ergonomic and psycho-social hazards)

7. Safety Measures (administrative control, operational control, engineering control and personal protective equipment)

4. 5 Steps of Risk Assessment 8. Good Health and Safety Management System

88

Defining Hazard and Risk

Hazard – is anything that has the potential to cause harm

Risk – is the chance of something happening that has the potential to cause harm.

Hazard RiskOpen drawer Chance of tripping over open

drawer and severity of injury

Identification of Hazards

Biological Hazards

• Viruses• Bacteria• Parasites• Insects• Mites• Fungi

Physical Hazards

• Noise• Vibration• Ionising &

Non ionising radiation

• Extreme temperature

• Electricity• Illumination

and visibility

Chemical Hazards

• Liquids• Gases• Vapours• Dusts• Fumes• Fibres• Mists

Mechanical and Ergonomic

Hazards• Posture traps• Movement• Repetitive

actions• Entanglement• Overexertion• Manual

handling• Slip, trips and

fall

Psycho-Social Hazards

• Worry• Stress• Individual• Work demand

and conditions

• Work environment

• Work pressure• Monotony• Unsocial hour

Identification of Hazards

1111

Risk Assessment

• A careful examination of what could cause harm to people in the workplace.

• The correct identification of the hazards and an appropriate estimation of the risk

• The basis for valid decision on control measures in the workplace to safeguard health of people at work and people in the premises

• It is important that we should be able to recognize or identify the hazard around the workplace in order to avoid the risk.

1212

Risk Assessment

1 • Identification of hazards

2• Deciding who might be harmed and how. Or

Who are affected?

3 • Evaluating the risks

4 • Recording

5 • Reviewing

1313

Biological Risk Assessment

Identify the hazards associated with an infectious agent or material

Identify the activities that might cause exposure to the agent or material

Consider the competencies and experience of laboratory personnel

Evaluate and prioritize risks

Develop, implement, and evaluate controls to minimize the risk for exposure

1414

Risk Matrix – Evaluation of risk

o To provide a better picture of the distribution of risks from the identified hazards which need urgent actions and mitigations

o The severity/consequence and the probability/likelihood of the risks are given a score from 1 to 4, with 1 least severe and 4 the highest.

o Risk rating = probability x consequence

o Results are colour coded to provide easy distinctions of priorities
