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) Occupational3) Social4) Personal5) Biological6) 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 notice important details)
• 4. Inspection (Officially looking closely to check on standards, scrutinizing,
surveying and investigation) • 5. Examination (Detailed inspection to analyze, apprise, assess the
subject)
• 6. Checking (Examining for accuracy, quality, conditions, standards, shortcomings, progress and compliance)
• 7. Testing (A procedure intended to establish the quality, performance or reliability, procedures include analysis, appraisal, assessment, auditing, checking, evaluation, examination, experimentation, inspection, interrogation, investigation, and probing)
TIPS TO REDUCE ACCIDENTS
• DAILY SAFETY PLEDGE.• SAFETY SUGGESTIONS FROM EVERY ONE.• PUBLIC ADDRESS SYSTEM AND SAFETY TALK.• SAFETY AWARD AND REWARD SYSTEM.• SAFETY OBSERVATION TOUR.• SAFETY ALERT MEETING.• NEAR MIS INCIDENTS REGISTER.• FAIL SAFE SYSTEM.• STRENGTHENING MINE SAFETY DEPARTMENT.• BRAIN STORMING SESSIONS.• YOGA AND MEDITATION.• STANDARD OPERATING PROCEDURE (SOP) AND CODE
OF SAFE PRACTICES (COSP).
Plans to be maintained
