1 Industrial Safety And Emergency Preparedness: NTPC Perspective Shivam Srivastava GM-Safety NTPC Limited Shivam NTPC 1

2 Pathway About NTPC Why Industrial Safety is Important NTPC Safety Policy Framework Major hazards in Power Station Emergency preparedness at Engineering stage Emergency preparedness at O&M stage Shivam NTPC 2

3 About NTPC Sl.No. NO. OF PLANTS CAPACITY (MW) NTPC Owned Coal 21 40,355 Gas/Liquid Fuel 7 4,017 Hydro Renewable energy projects (Solar PV) Wind 1 50 Total 42 46,100 Owned By JVs/Subsidiaries Coal & Gas 9 7,551 Total 51 53,651 Shivam NTPC 3

5 What is Safety?? Safety is not absence of accidents Safety is presence of defenses in the processes, procedures, facilities, methods and practices. Shivam NTPC 5

6 What is Industrial Safety?? Industrial safety is defined as policies and protections put in place to ensure plant and factory worker is protected from hazards that could cause injury. Shivam NTPC 6

7 Why Industrial Safety is important Occupational/ industrial accidents result in loss of production time equivalent to millions of man hours, machine hours etc. 20% production time is lost by those actually injured due to temporary and permanent disablement Balance 80% production time is lost by fellow operators/ people in helping the injured, in taking care of the damage caused by accident etc. Shivam NTPC 7

8 Intent of NTPC Safety Policy Framework All Accidents Are Preventable Therefore, safety must be at the forefront of all activities Copyright 2016 Your Company All Rights Reserved. 8

9 Six Principles of NTPC safety Policy 1. Our activities carry various hazards; however all hazards can be identified. 2. Every job shall be done safely, no matter how important or urgent it is. 3. Putting people to work carries a specific responsibility and accountability for safety which shall be visibly demonstrated. 4. Right procedures and actions can bring the risks under control. 5. Trained and committed team can ensure incident free operations. 6. Compliance to all applicable safety regulations and other legal requirements at the minimum. Shivam NTPC 9

18 Generic and application sector standards Machinery sector Medical sector IEC IEC IEC Nuclear sector IEC Process sector sector IEC is an international standard published by the International Electrotechnical Commission of rules applied Shivam NTPC 18 in industry.

19 IEC IEC is an international standard published by the International Electrotechnical Commission of rules applied in industry. It is titled as Functional Safety of Electrical/Electronic/Programmable Electronic Safety-related Systems (E/E/PE, or E/E/PES). Shivam NTPC 19

20 Safety Specifications EN :2015 : Electrical equipment for furnaces and ancillary equipment. Requirements for application design and installation EN : Electronic equipment for use in power installations. NFPA-85 Contributes to operating safety and prevents explosions and implosions in boilers IS-3034 Fire safety of Industrial Buildings Shivam NTPC 20

21 Emergency Preparedness At O&M stage Shivam NTPC 21

22 Process Safety : Implementation Capacity building on DMP / OD/ OGN/ OIN and LMI. Awareness of Process Hazards and mitigation actions. Implementation of LMIs with Zero Tolerance. No deviations from NTPC safety systems (PTW / TC/ Process protections, General safety Rules etc) Shivam NTPC 22

23 Disaster Management Plan United Nations International Strategy for Disaster Reduction (UNISDR) International decade for Disaster reduction Hyogo Framework ( ) Sendai framework ( ) Shivam NTPC 23

24 Sendai Framework Priority 1. Understanding disaster risk Priority 2. Strengthening disaster risk governance to manage disaster risk Priority 3. Investing in disaster risk reduction for resilience Priority 4. Enhancing disaster preparedness for effective response and to Build Back Better in recovery, rehabilitation and reconstruction Source: Shivam NTPC 24

25 Emergency Preparedness Well defined Disaster Management Plan Pre disaster elements: Prevention and Risk Reduction Preparedness Post disaster elements: Response Recovery Shivam NTPC 25
