BEHAVIOUR BASED SAFETY

Holnagel, 1993 study 90% of work place

accidents caused due to unsafe behavior of

persons.

Workers stress and risk taking behavior.

Analysis of accidents on technical error

approach without considering human error

approach.

HUMAN BEHAVIOR AND STRESSStress is a state of affair involving demand on

physical or mental energy.

Contributing factors.

1) Environmental

2) Occupational

3) Social

4) Personal

5) Biological

6) Psychological

SYMPTOMS OF STRESS

1) PHYSICAL - Headache, B.P. raise, Heart

problem, Bowel syndrome, weight loss,

depletion of immune system

2) PSYCHOLOGICAL Anxiety, anger,

frustration, depression, memory loss, lack

of motivation, lack of concentration,

accident proneness.

CHARACTERSTICKS CONTRIBUTING TO

ACCIDENTS

1) INDIVIDUAL Experience, knowledge,

skills, attitude towards safety.

2) JOB Work task, work environment, job

stress

3) MINE- Safety culture, social support,

safety management systems.

IMPROVE YOUR SKILLS

1. Seeing (Catch sight of, become aware of things around)

2. Watching (Look at attentively, keeps eyes open, pay attention)

3. Observation (Action of closely observing someone or something to noticeimportant details)

4. Inspection (Officially looking closely to check on standards, scrutinizing,surveying and investigation)

5. Examination (Detailed inspection to analyze, apprise, assess thesubject)

6. Checking (Examining for accuracy, quality, conditions, standards,shortcomings, progress and compliance)

7. Testing (A procedure intended to establish the quality, performance orreliability, procedures include analysis, appraisal, assessment, auditing,checking, evaluation, examination, experimentation, inspection, interrogation,investigation, and probing)
