High temperatures are a potential challenge to electrical equipment which may have essential safety functions. These SAPs therefore require a level of interpretation by the assessor and make it clear that all relevant external hazards should be considered when determining the design basis events for both probabilistic and deterministic safety cases and provide the numerical targets for assessing whether the risk from external hazards is tolerable and ALARP.

If a Haizd is not used to demonstrate the absence of an adverse cliff edge effect either an approximate PSA approach may be undertaken a NUREG describes a technique for earthquake hazard or a deterministic-plus-engineering judgment approach may be made.

Doing HAZID in Excel

Seismic Seismic hazard definition should include a reasonable frequency distribution of accelerations, i. Each area of the installation is considered against a checklist of hazards. As with the other environmental hazards it is important to ensure that the most up-to-date information available for a specific site is used in the hazard assessment.

You may see the following warnings:. The possible effects on safety related equipment from a nearby impact may need consideration.

Further details of a particular method are published by the IAEA see below. Aircraft crash For aircraft crash structural demand depends on the worksehet, rigidity, velocity and engine location of any aircraft assumed to impact directly or skid onto the structure, and also the angle of incidence of the impact direct or skidding.

Typical problems could be wind tunnelling between tall structures, or vortex shedding from upwind facilities.


This has the merit, usually, of exploring the response of the plant to a wide range of hazard levels and is wrksheet internationally as a reasonable approach for external hazards. By its very nature the definition of the flooding hazard at small annual probabilities of exceedance will be subject to significant uncertainty and it must be assumed that the natural phenomena which can be the cause of flooding may occur together.

Seismic hazard definition should include a reasonable frequency distribution of accelerations, i.

This is generally known as the cliff edge effect. Design by Arie Gumilar Further guidance is available from the IAEA. In the case of external flooding, for example, the site defences become overtopped.

HAZID Hazard Identification ~ Chemical Engineering Processing

It has also been demonstrated workshee numerous earthquakes that structural ductility is very desirable. Licensees, any particular application should be assessed to ensure that there are no plant specific, i. However, if this approach is adopted, the assessor should ensure that the hazard definition is reasonable for the more remote levels and that relevant equipment responses are reasonable, i.

Impacts and Shock loading This can be due to external explosions and overpressures giving rise to shock loading and drop loads or impacts due to facility collapse, which may include cranes, building structures and systems. To check if you have the Advanced features, follow these steps: The effects of climate change should also be taken into account see section 4. A dialog pops up.

You can now drag elements from the scrap book onto your BowTie diagram. The design basis analysis principles and the PSA principles should be satisfied, as appropriate, taking into account the direct impact of the aircraft on the structures, systems and components important to safety, secondary missiles, vibration effects and the effects of aircraft fuel burning externally to the buildings or other structures, or entering the buildings or structures.

The assessor should establish that the potential threats are recognised by the operators and appropriate prearranged responses are embodied in operating instructions. Actions are assigned to either discipline groups or individuals to ensure the mitigating control, or further study is completed.


Feedjit Live Blog Stats. Typical hazards, which may arise from industrial plants, may be from stored gas, fuel, explosives, pressure vessels or turbine disintegration. The external hazards safety case should consider all potential sources of external missiles and explosion.

The hazard sheets contains four risk matrices: Cliff edge The Licensee will also need to demonstrate that there will not be a disproportionate increase in risk from an appropriate range of events which are more severe than the design basis event. The Process of Hazard Identification is the procedure to assess all the hazards that could directly and indirectly affect the safe operation of that plant and or system, and is referred to as the Hazard Identification procedure or HAZID.

For each of the hazards, a spreadsheet will be generated. The procedure of hazard identification is broken down and categorised into the two streams that can affect the system both directly and indirectly, and is referred to as Internal Hazards and External Hazards.

HAZID – HAzard IDentification Studies

Macros have been disabled. Share information about chemical engineering knowledge. Here the Licensee should consider the withstand to shock loading, the possible impactors to the system from the facility, determining the largest single mass object from its potential drop height in free fall without structural interaction, or make a case for the probable but bounding collapse dynamics of the facility which can in some cases include structural interaction.

This is likely to include extreme ambient temperatures, wind and flooding. In assessing safety systems claimed hazzid mitigate the effects of external hazards, the assessor should have due regard to Reliability, redundancy, diversity and segregation.
