GIUSP - Edition 7.1

Edition 7 of the Gas Industry Unsafe Situations Procedures was published on 01 Jul 15 (and subsequently amended to edition 7.1 on 10 Dec 15) with an immediate implementation date. Gas Safe Register allowed a period of 12 months for businesses to adopt the procedure and amend their business policies to reflect the changes. We sent a newsletter to all of our subscribers on 30 Jun 15 outlining these changes which received one of our highest viewing figures.

What this means for businesses is that with effect from 01 Jul 16 Gas Safe will be expecting all business to be operating from the current edition. If you've not had chance to look at the current edition you can download it by logging into the engineers section of the Gas Safe website.

There are a few significant changes from Edition 6:
  • Appliances are either classed as Safe or Unsafe. As a result the NCS category has been removed from the procedure. These are still notifiable to your customer via job sheets, reports, etc but do not form part of the GIUSP.
  • There are some situations where turning the gas off will not remove the risk. These are dealt with slightly differently.
  • The removal of NCS from the procedure has also removed the option of "NCS Stacking" for two or more Flueing and/or ventilation defects. The GIUSP now lists "one or more likely to affect the safe and effective performance" as AR depending on the gas operative's assessment
The GIUSP is there as a handy reference for you in the event of encountering any unsafe situation. It will also confirm the actions needed to take on discovering a gas incident, and also requirements under RIDDOR.

Is it something that you can really leave out of your toolbox?


The CPA1 assessment (Combustion Performance Analysis) was incorporated into CCN1 (and other Core Assessments) in April 2012. Prior to this it stood as a standalone assessment, not necessarily running in conjunction with a Core Gas assessment. As a result a number of operatives completed their Core Gas element prior to April 2012 without renewing their CPA1. By April 2017 everyone will have completed the ACS cycle and will have undertaken their Core Gas element incorporating CPA1

This has left some operatives with the situation that their CPA1 expires before their Core Gas does. It is a requirement for anyone working on Boilers/Fires to have a current CPA1 assessment. Operatives who allow their CPA1 to expire are no longer permitted (and will not appear on the GSR website) to work on Boilers/Fires.

Holding a CCN1 (or other Core Gas) does not automatically grant you CPA1 if it was taken prior to April 2012. Please ensure that you do not allow your CPA1 to expire and risk working out of scope.

PD 54823:2016

PD 54823 (Guidance for the design commissioning and maintenance of LPG systems in small craft) has been released by BSI. With the majority of BS 5482 (Parts 1-3) being subsumed by other standards it was decided that PD 5482-3 would be reclassified as PD 54823.

This revised document is now more aligned to BS EN ISO 10239 and is to be used as a maintenance "standard" for existing installations. PD 54823 does not cover any of the following:
  • Any new installations (irrespective of their intended use)
  • Major changes (majority of piping raplaced) to an existing installation
  • Additional appliances
In these cases the installation should comply with the requirements of BS EN ISO 10239

Previously there was some confusion over where the requirements of PD 5482-3 2005 stopped and BS EN ISO 10239 began. PD 54823 is quite clear in this demarcation and it is purely to be used as a maintenance "standard" for existing installations. 

PD 54823 (and other British Standards, IGEM and UKLPG documents) are available to all Gas Safe Registered engineers via the Standards Subscription service. This is priced at £75 per year for a company with 1-5 operatives, £150 for those with 6-10. Reduced prices are available for three year subscriptions.
