Bringing down the pyramid

• However with the current statistics and further bringing down the pyramid we can safely conclude the following

Severity & Compliance Number Severity No. Description

1 Untidy/Unclean (don’t meet standards)2 Sets Bad Example (partially blocked ways)3 Rules and Procedural Violations4 Serious Hazard (Can cause injury if not

corrected)5 Imminent Danger (Stop work and correct immediately. Will cause serious injury or fatality)

1S: Untidy/Unclean• Paper cups and trash on ground. Paper cups and trash on ground.• Poor maintenance of safety signs poor maintenance of safety signs• Loose scrap scattered around loose scrap scattered around• Trash on road side drainage trash on road side drainage

2S: Sets Bad Examples• Trash or material block access• Trash not stored properly.• Inadequate access to work areas.

3S: Rules and Procedural Violations• Not wearing PPE• Cords across walkway/tripping hazards• Incomplete scaffolding• Ladder not secured

3S: Rules and Procedural ViolationsContinued

4S: Serious Hazard• Incomplete scaffold• Incomplete barricade• Inadequate fall protection, no one present• Inadequate lock out protection

4S: Serious HazardContinued

4S: Serious HazardContinued

5S: Imminent Danger • Worker at height with inadequate fall protection• Worker without proper lock protection• Worker in excavation without adequate protection• Confined space violation

5S: Imminent DangerContinued

5S: Imminent DangerContinued

Scope• Initially at HZL, 3S, 4S & 5S violations are to be

focussed only. • Once, the nos of 3S, 4S & 5S violations and

their compliance are within comfortable range in the unit, 2S violations will have to be included for scoring. Similarly, 1S violation to be included thereafter.

• Decision of incorporating 2S & 1S are to be taken by HSE Head in consultation with unit head.

Severity Number & Compliance3S

– Nos of 3S violations in unit= 15– Nos of compliance of above violation= 12

4S– Nos of 4S violations in unit= 8– Nos of compliance of above violation= 6

5S– Nos of 5S violations in unit= 5– Nos of compliance of above violation= 5

• Severity No of unit = (15-12)*3 + (8-6)*4 + (5-5)*5 = 17
