Sparrow Risk Management Private Limited

Objective of Hazid:

HAZID studies involve identification of hazards and the events, which may lead to risk to either people, Environment, Asset .The objective of Hazid is to identify the potential hazards and to reduce the probability and consequences of an incident in site that would have a detrimental impact to the personnel plant, properties and environment. HAZID is critical to safety duties and the safety report Employer must identify all major accidents and their related causes using a systematic and documented HAZID approach

Scope of study : It will depend on the particular project.

• Identify opportunities for inherent safety
• Identify Fire, explosion, toxic release scenarios and measure to prevent it.
• Any special preparations required to be taken to handle these can be pre – planned.
• Any specific process modifications if required can be established at an early stage.
• Prepares the system & team, ready and confident to go ahead for commissioning. Avoids major surprises.
• Hazards involved in operating each equipments can be enlisted at the beginning, leading to better process mapping & better control in future to getting OSHAS / ISO approvals.
• The major benefit of HAZID is early identification and assessment of the critical health, safety and environmental hazards provides essential input to the project development decisions.

• To the extent possible the audit will follow all applicable standards (international)

• To identify, quantify and assess the risk from the facility from the storage and handling of chemical products
• To identify, quantify and assess the risk to nearby facilities / installations.
• To suggest recommendations in order to reduce the risk to human life, assets, environment and business interruptions to as low as reasonably practicable.

1. Quantitative Risk Assessment for the Monomer Tanks and Solvent Tanks.

• Impact analysis shall be done for any leakage or catastrophic rupture/explosion of the storage tanks (depending on MSDS of the chemical).
• QRA Study shall include the responses on the Individual Risk, Property Risk and Environmental Risk.
• QRA methodology and related software (PHAST RISK) shall be utilized for the contouring the area, pertaining to the impact of the explosion / fire incidents in the tanks.

2. Contouring of area based on presence of flammable air-gas mixture.

A latest version of the renowned software “PHAST RISK (Version 6.7)” is used to estimate the overall risk. It requires the following data:

• Location of releases
• Type of release
• Maximum extent of each potential hazard for each release
• Location of ignition sources and ignition probability and/or algorithm
• Wind rose, speed and stability distribution data

Software Used – PHAST RISK (Latest Version 6.7)

Standard & Regulations:

• Centre for Chemical Process Safety of AICHE
• UK – HSE Failure Frequency Database
• Purple Book – CPR 18E ‘Guidelines for the Quantitative Risk Assessment’
• IS 15656 – Hazard Identification & Risk Assessment Procedure – Code of Practice

Additional Details:

Fire & Gas Mapping studies aim to assess a detector layout against the pre-specified performance targets for detecting a reference flame or gas cloud. Performance targets for specific areas of a facility are generally agreed in advance of the study and aligned with the overall Fire & Gas Safety Philosophy and applicable standards or good practice guides.

Flame detection mapping determines the number of detectors triggered in each location as the reference flame is moved across the assessment area. The method requires a 3D representation of the facility in order to fully account for the blockages to visibility created by the equipment. Existing 3D models can be imported in a range of formats and models used for explosion assessment can be used directly. If no 3D model is available representations of major obstructions can be incorporated manually based on layout and elevation drawings. Detector layout can then be optimized to ensure defined performance targets are achieved.

Any restrictions in detector mounting for access and maintenance (such as detector height) can be accounted for in the optimization. For both fire and gas mapping, the relative contribution from each detector to the overall coverage is determined. This drives the optimization by

Factors For Disaster Management Risk Reduction

Prevention: outright avoidance of the adverse affects of hazards / disasters

Mitigation: the process of lessening or limiting the adverse affects of hazards / disasters

Preparedness: knowledge and capacities to effectively anticipate, respond to and recover from impacts of likely hazard

Risk Reduction: practice of reducing risks through systematic efforts to analyze and manage the causal factors of disasters, including through reduced exposure, lessened vulnerability, improved preparedness

Response: provision of emergency services to save lives, meet needs from response to hazard risk management:

• Starting with the community
• Adopting a whole-of-government approach
• Developing National Action Plans
• From external intervention to national capacity building
• Training programmes
• Transfer of knowledge and skills

HAZOP studies, which are common in the industry, provide a means to systematically identify deviations from design, The Objective of HAZOP study is to identify the hazard and operability problems and to reduce the probability and consequences of an incident in the process facilities that would have a detrimental impact to the personnel plant, properties and environment.

The HAZOP study will cover every line and piece of equipment capable of producing an event that could lead to serious injuries or equipment damage

Scope of study will include all process and utility P&IDs forming the scope of the project, all interface P&IDs, outstanding items from the previous HAZOP study, Operating and control philosophy, vendor data etc.

The HAZOP will be conducted to examine the overall process design, searching for operating deviations and process interactions that can lead to hazardous situations or operability problems, which include:

• Review of the design and operation of process facility
• Safety and occupational Health Hazards to personnel
• Damage to equipment/asset/environment
• Operability/maintainability problems
• Plant non-availability/limitation and lack of product quality
• Environmental emissions
• Construction and commissioning hazards
• To identify all possible causes of deviations from normal operation that could lead to any safety hazard, environmental risk or operability problem
• Identification of hazards, possible causes and consequences and suggest recommendations for necessary changes/ alterations
• Critical examination of the process and the engineering intentions to assess the hazard potential or mal-operation or mal- function of individual items of equipment and the consequential effects on the facility as a whole.

To the extent possible the audit will follow all applicable standards (international)

Objective of the Project:

To identify:

1) Immediate causes
2) Underlying causes / Root causes of the fire incident

Client shall confirm the same or suggest suitable changes, if any Scope of the Project. Scope of the project includes the followings:

1. Gathering the information:

To find out what happened and what conditions and actions influenced the adverse event.

Note: It is important to capture information as soon as possible. This stops it being corrupted, e.g. items moved, guards/barrier replaced etc. If necessary, work must stop and unauthorised access be prevented.

2. Analysing the information:

An analysis involves examining all the facts, determining what happened and why. All the detailed information gathered shall be assembled and examined to identify what information is relevant and what information is missing. The information gathering and analysis are actually carried out side by side. As the analysis progresses, further lines of enquiry requiring additional information will develop.

3. Identifying suitable risk control measures:

The methodical approach adopted in the analysis stage will enable failings and possible solutions to be identified. These solutions need to be systematically evaluated and only the optimum solution(s) should be considered for implementation. If several risk control measures are identified, they should be carefully prioritised as a risk control action plan, which sets out what needs to be done, when and by whom.

To the extent possible the audit will follow all applicable standards (international)
