‼️ HUMAN FACTORS & BEHAVIOUR ‼️

 ‼️ HUMAN FACTORS & BEHAVIOUR ‼️ 

1. What are Human Factors?

Human factors are the conditions, influences, and characteristics that affect how people behave at work.

👉 They directly impact:

Safety

Productivity

Decision-making

2. Three Main Areas of Human Factors

A. Job Factors (Work Design)

Workload (too much / too little)

Time pressure

Complexity of task

Availability of tools & equipment

✔ Positive Influence:

Clear procedures → Safe behaviour

Proper tools → Efficient work

❌ Negative Influence:

High workload → Mistakes

Poor design → Unsafe shortcuts

B. Individual Factors (Personal)

Skills & competence

Attitude & motivation

Fatigue & stress

Health condition

✔ Positive Influence:

Trained worker → Safe decisions

Good attitude → Compliance with rules

❌ Negative Influence:

Fatigue → Reduced concentration

Overconfidence → Risk-taking

C. Organizational Factors (Management System)

Safety culture

Supervision

Communication

Training systems

✔ Positive Influence:

Strong safety culture → Safe behaviour

Good supervision → Early correction

❌ Negative Influence:

Poor communication → Misunderstanding

Weak enforcement → Rule violations

3. How Human Factors Affect Behaviour

Positive Behaviour (Safe Work)

Following procedures

Using PPE properly

Reporting hazards

Team coordination

👉 Happens when:

Work is well planned

Workers are trained

Environment is supportive

Negative Behaviour (Unsafe Acts)

Taking shortcuts

Ignoring PPE

Poor judgement

Violating procedures

👉 Happens when:

Stress or fatigue is high

Poor supervision

Lack of awareness

4. Common Human Errors

Slip → Action error (e.g., pressing wrong button)

Lapse → Memory failure

Mistake → Wrong decision

Violation → Breaking rules intentionally

5. Key Causes of Unsafe Behaviour

Time pressure

Fatigue

Poor training

Lack of supervision

Bad safety culture

Distractions

6. Control Measures (Improvement Actions)

Engineering Controls

Better equipment design

Automation

Administrative Controls

Training & competency

Clear procedures

Job rotation (reduce fatigue)

Behavioral Controls

Safety awareness

Positive reinforcement

Supervision

7. Key Training Message

👉 “Unsafe behaviour is often caused by system failures, not just worker fault.”

👉 Focus on:

Improving system

Supporting workers

Building safety culture

8. Quick Takeaway

✔ Right environment → Safe behaviour

 ❌ Poor conditions → Unsafe behaviour
