AIM

To review existing emergency management plan and fire safety system and to recommend further improvement to increase their efficiency and promote high integrity of safety culture in underground metro construction, at “Pratibha Industries Limited, New Delhi”

OBJECTIVE

Analysis of the previous emergency manual.

Identifying hazards that can cause accidents, illness or damage to environment.Control measures to minimize the hazards

Developing communication system for emergency situationProvide training and resources to employees to maintain SHE systems

SCOPE

Regular updating of emergency evacuation plan is required as construction site changes time to time

INTRODUCTION

• An emergency is a serious, unexpected, often dangerous situation that requires immediate action

• An emergency evacuation is the immediate and urgent movement of people away from the threat or actual occurrence of a hazard

• The emergency procedure is a plan of actions to be conducted in a certain order or manner, in response to an emergency event.

METHODOLOGY

Hazard Identification/

Assesment

Emergency Resources

Communication System

Administration of Plan

Emergency Response Procedure

Communication Of Procedure

Debriefing And Post-traumatic

Stress Procedure.

HAZARD IDENTIFICATION

• EXCAVATION• LIFTING OPERATION BY CRANES• TBM INSTALLATION AND LAUNCH• TBM INITIAL DRIVE• TBM TUNNELING OPERATION• ROLLING STOCK• RING BUILDING• CHEMICAL GROUTING• CUTTER HEAD INTERVENTION• BREAK THROUGH OF TBM• BOX PUSHING

Level 3

• Vertical evacuation

Level 4

• Complete facility evacuation

SUMMARY

CONCLUSION

Each and every individual must be very much aware of their parts and obligations amid crisis as specified accordingly arrange so that the human and also financial misfortune can be lessened to least.

The course of action should be used to complete and pass on the emergency response systems, and certification that any required get ready has been done.

The plan must be evaluated at predictable time interval to ensure that it fits in with current operations and conditions.
