DEFINITIONS Cause Event, situation, or condition that results, or could result, directly or indirectly in an accident or incident. Competent Describes an individual with knowledge and skills deemed acceptable by the engineering authority (EA) to perform a task. Appropriate knowledge and skill may be acquired through training, experience, qualifications, or some combination of these. Consequences Direct, undesirable result of an accident sequence usually involving a fire, explosion, or release of toxic material. Consequence descriptions may be qualitative or quantitative estimates of the effects of an accident in terms of factors such as health impacts, economic loss, and environmental damage. Hazard Condition or practice with the potential to cause harm to people, the environment, property, or reputation. Hazard identification (HAZID) Brainstorming approach used to identify possible hazards. HAZID studies are very broad in their scope. The HAZID is sometimes called a Preliminary Hazard Analysis. Hazard and operability (HAZOP) Systematic qualitative technique to identify and evaluate process hazards and potential operating problems, using a series of guidewords to examine deviations from normal process conditions. Independent protection layer (IPL) Device, system, or action that is capable of preventing a postulated accident sequence from proceeding to a defined, undesirable endpoint. An IPL is (1) independent of the event that initiated the accident sequence and (2) independent of any other IPLs. IPLs are normally identified during layer of protection analyses. Initiating cause A failure, error, situation, or condition that results or may result in the propagation of a hazardous event. Risk A measure of loss / harm to people, the environment, compliance status, Group reputation, assets or business performance in terms of the product of the probability of an event occurring and the magnitude of its impact. Throughout this Practice the term “risk” is used to describe health, safety, security, environmental, and operational (HSSE&O) undesired events. Node A discrete area or portion of an activity, plant, or system that permits a stepwise approach towards progressing through the HAZID. Safeguards Device, system, or action that would likely interrupt the chain of events following an initiating cause or that would mitigate loss event impacts.

What If analysis Scenario based hazard evaluation procedure using a brainstorming approach in which typically a team that includes one or more persons familiar with the subject process asks questions or voices concerns about what could go wrong, what consequences could ensue, and whether the existing safeguards are adequate.

HOLDS No holds.

INTRODUCTION United Energy Pakistan is conducting a HAZID review of Naimat Phase-V Gas treatment and LPG extraction project. The project is in FEED stage. HAZID inputs will become pat of basis for Detailed Design. A two days session is planned to be conducted at UEPL head office in Bahria Complex-1 on 17th & 18th of Feb 2014.

1.1

Workshop Scope The HAZID will look into Naimat Phase-V scope only. Existing on-going projects, Phase-IV and TAR will not be subject of this HAZID however hazards due to SIMOPSs and any interconnectivity between existing and new units will be considered in this HAZID scope. The purpose of HAZID is to: 

Identify potential hazards as defined in the TOR for the HAZID study.



Consider consequences of the hazards.



Identify safeguards that are in place to provide hazard prevention or mitigation.



Propose recommendations, as needed, to eliminate, prevent, control, or mitigate hazards.



Provide assistance to facility management in its efforts to manage risks.



Support objectives of ISD.

METHODOLOGY HAZID will be carried out as per industry standard practices. HAZID will look into Major Accidents as well as HSSE hazards. A set of guidewords or brainstorming reference list will be used during the session. HAZID team will be encouraged to consider more deviations / hazards which may be missing in generic list. For each guideword team will brainstorm potential consequences and list existing safeguards and generate recommendations for further mitigation if required. A risk Matrix (8x8) will be used to risk rank all the identified harzards. HAZID Proceedings will be recorded on a worksheet. Draft worksheet is attached (SHERAZ TO ATTACH UPDATED HAZID WORKSHEET)

C

5 years.

BP's commitment to health, safety and the environment is paramount; this is reflected in BP’s HSE goal of "No Accidents, No Harm to People, and No Damage to the Environment". No accident, injury, or loss of containment causing damage to the environment is ever “acceptable” to BP. BP is using this framework (equivalents of which are used throughout industry) to support the consistent prioritization of actions to eliminate or mitigate HSE risk and as part of BP's Performance Improvement Cycle to deliver continuous risk reduction.
