SAFETY ISSUES IN CGD INDUSTRY

Group 5Roll No. 20121041 to 20121050

Agenda

Overview HSSE Policy Safety Measures- Functions of OISD IMS for CGD

HSSE Policy

Effective health, safety and security performance across CGD operations depends on a commitment to maximize awareness of these risks at every level of the organization.

Zero injury goal could be achieved by; Preventative maintained Internationally accepted good practice Everyone’s responsibility and duty to intervene to prevent

unsafe actions and to reinforce good behaviors through demonstrating HSE leadership.

 Implementing this policy need to ensure -

Management decisions reflect our HSE intentions HSE management system reflects best industry practice

and is properly resourced Continuously  improvement of HSE performance by

acting on lessons learnt ;

to avoid  work related ill health, accidents, and incidents, to prevent  pollution  and to minimize environmental emissions, waste and energy use.

Ensure and maintain compliance with all legal requirements  to operate business and which relate to its environmental aspects and OH&S risks.

Provide direction, education, training and supervision to ensure all employees are competent and understand their accountabilities, the required behavior and the consequences of non compliance

Ensure that contractors and suppliers understand their HSE accountabilities and required behavior, share our aspirations and are aware of the consequences of non compliance. Sharing and learn from each other’s experiences

Work with partners to achieve internationally accepted good practice in HSE and learn continually from each other’s experiences

Adopt a risk based approach to the design, construction and operation of our facilities across their life cycles

Involve and consult all our Stakeholders and take into account their concerns on HSE

Report on our HSE objectives together with performance and work with industry and government agencies to improve HSE practices

Policy is used as a framework for setting and reviewing Environmental and OH&S objectives and targets.

Core Values

Injury and incident free organization, this means: Trust - Developing trust through fair treatment Confidence - Ensuring people feel confident to act Empowerment - Empowering people to take action on safety Zero Tolerance - Never compromising on safety and taking

action on safety

Asset Integrity

ASSET INTEGRITY ACHIEVED BY:

Application of the national and International codes & standards

The use of industry best practices Utilizing effective techniques and systems to

prevent failures by identifying hazards, potential consequential failures and undertaking necessary mitigation actions

Ensuring all personnel required to work on the network are trained and competent

Monitoring performance, review and amend as required to achieve this goal

Involvement of all stakeholders This endeavor shall be supported by the

provision of all the necessary resources

Decommissioning & Disposal

If you smell gas :

Open all Doors and Windows Turn off your gas supply at the meter Do not switch on or off any electrical switch Extinguish

all naked flames Call emergency service no 1800XXXXXX

Petroleum and Natural Gas Regulatory Act, 2006

Covered under ASME B 31.8 Technical and safety audits during the construction,

commissioning and operation phase, as well as on an on-going basis as may be specified from time to time.

Technical Standards and Specifications including Safety Standards For City or Local Natural Gas Distribution Network Schedule – 1A Materials And Equipment Schedule – 1B Welding Schedule – 1C Piping System Components And Fabrication Details Schedule – 1D Design, Installation And Testing Schedule – 1E Operating And Maintenance Procedures Schedule – 1F Corrosion Control Schedule – 1G Miscellaneous

Safety Awareness

CNG PNG

Safe Refilling instructions followed for all CNG Vehicles at CNG Station

Safety symbols & cautionary instructions displayed all around

Safety films screened at CNG Stations frequently to educate consumers

Safety leaflets / Stickers developed for awareness on specific occasions

Free Compliance Plate given to all public transport fleet running on CNG through transport deptt

Safety clinics conducted for customers

Safety leaflets / Stickers developed and distributed

24Hrs customer care number.

ERDMPEmergency Response and Disaster Management Plan

Integrity management plan for city gas distribution networks through Evaluating the risk associated with city gas distribution

networks and effectively allocating resources for prevention, detection and mitigation activities.

Improving the safety of city gas distribution networks so as to protect the property, public and environment.

Bringing more streamlined and effective operations to minimize the probability of pipeline failure.

Functions of OISD

Develop Standards Liaise with statutory organizations Safety audits Information regarding disasters Enquiries in accidents Reviewing Specify critical drawing/Lauouts

Need of an Effective IMS

Ensuring the quality of CGD network integrity in all areas which have potential for adverse consequences

Promoting a more rigorous and systematic management of CGD network integrity and mitigate the risk

Increasing the general confidence of the public in operation of CGD network

Optimizing the life of the CGD network with the inbuilt incident implementation of IMP investigation and data collection including review by the entity.

Integrity Management

Plan (IMP)

Performance evaluation of

IMP

Quality Control

Management of Change

Communication Plan

Elements of IMS

Four aspects should be visualized during data collection:Data alignment, Data history, Data Normalization, Data accuracy and confidence

Time Dependent Threats-- 1) External Corrosion 2) Internal CorrosionStable Threats--Manufacturing related defects, Welding /fabrication related, EquipmentTime independent Threats- Third party /mechanical damage, Incorrect operational procedure

Initial Data Gathering

Threat Identification

Evaluation of Threat

Consequence and Impact Analysis Identification of High-consequence area (HCA)

Risk Assessment/Evaluation

Risk rating = Probability rating X Consequence rating

Hydro testing before commissioning at test pressure as per T4S standardExternal Corrosion Direct Assessment(ECDA)Cathodic protection system surveys etc.

HSE issues in CGD business

High transmission pressures Remote location of transmission pipelines (high emergency

response time) Distribution lines pass through thickly populated areas No control of source of ignition near pipelines Pipelines are buried; hence maintenance and leak detection is

tedious Consumers are not well equipped to deal with exigencies Unplanned/ un-notified dredging by external agencies Use of non-standard fittings by the customer (CNG kits)

Possible solutions

Use of SCADA/ GIS to map remote pipeline networks Automatic isolation valves Customer education programs Proper route mapping and marking as hazardous zone Proper Leak Detection Equipments to prevent major disasters Synchronization with local bodies/ agencies to avoid pipeline

damage, notifying fire brigade about new gas pipeline routes in a given area

Undertake Asset Integrity Management (AIM) of all equipments Follow design/ operating standards as prescribed by OISD Prepare robust Disaster Management Plan (DMP) to deal with

disasters
