Limited Scope assessments

In our series of articles explaining the ACS modules, Steve Mulvany, Logic Certification scheme director, provides an overview of the ACS assessments that are designated ‘Limited Scope’.
Introduction
During the ACS’ creation the gas industry was consulted on how competence assessments should be developed and delivered. It was clear that each sector of industry wanted assessments that were bespoke for their area of work. This approach led to a number of ACS assessments being deemed ‘Limited Scope’, for engineers who only ever carry out very specific work activity. The advantage of undertaking Limited Scope assessments is that they provide businesses and engineers with a cost-effective route to demonstrating competence as they by-pass the more general requirements for installers working on a number of gas appliances.
To prevent engineers taking a ‘shortcut’ into the gas industry without relevant experience and training, the ACS rules prevent those engineers who have taken a Limited Scope assessment progressing and extending their ACS certification to other activities without undertaking an extended program of managed learning.
The following Limited Scope Assessments are available:
Metering
CMA2LS & MET3LS are designed for gas engineers who only install low pressure-fed domestic gas meters, up to and including 6m3/hr, with the outlet capped – i.e. not connected to installation pipe-work. Both assessments must be completed together and consist of practical performance and written knowledge questions, where engineers must demonstrate their competence in the following:
* Gas safety legislation and standards
* Gas emergency actions and procedures
* Installation of pipework and fittings (pipework within meter installation)
* Tightness testing and purging
* Checking and/or setting meter regulators
* Unsafe situations, use of emergency notices and warning labels
* Install and commission domestic gas meter installation*
CMA2LS & MET3LS can be completed by a well prepared engineer within 1 – 1½ days.
Note, where the meter is to be installed to a medium pressure fed gas supply the ACS assessment REGT1 must be undertaken.

Commercial
ICPN1LS is for the engineer who only ever installs gas pipework in industrial and commercial premises that is not connected to a live gas supply. This assessment is typically undertaken by a pipe fitter/welder who fabricates and installs gas installation pipework on site.
The assessment consists of practical performance and written knowledge questions where engineers must demonstrate their competence to identify, join and install commercial gas pipework, valves and fittings. There are no pre-requisites and ICPN1LS can be completed by a well prepared engineer within 1 day.
ICAE1LS is for engineers who only ever assemble and installs commercial appliances that are not connected to a live gas supply e.g. boilers and air heaters. The assessment consists of practical performance and written knowledge questions where engineers must demonstrate their competence in the ‘first-fix’ installation of commercial appliances. Like ICPN1LS, there are no pre-requisites to taking the assessment and it can be completed by a well prepared engineer within 1 day.
Note: It is acceptable and a common approach for engineers to undertake a combination of ICPN1LS and ICAE1LS assessments.
COCNPI1LS is a core gas safety assessment for engineers who only install and test commercial pipework which is connected to a live gas supply. COCNPI1LS must be completed with ICPN1 (Installation of Commercial Pipework) and either TPCP1 or TPCP1A (Tightness Testing & Purging of Commercial Pipework). The one exception is that COCNPi1LS can also be used as a Limited Scope core pre-requisite to CGFE1 (Commercial Gas Fired Engines) for engineers who only work on engines which are fitted within a stand-alone acoustic enclosure where no other appliances are fitted.
The assessment consists of practical performance and written knowledge questions where engineers must demonstrate their competence in the following:
* Legislation and standards
* Installation of pipework and fittings
* Tightness testing and purging (IGE/UP/1B)
* Unsafe situations
* Use of emergency notices and warning labels
* Operation and positioning of emergency isolation controls and valves
COCNPI1LS can be completed by a well prepared engineer within 1 day (note, this duration does not include ACS assessments ICPN1, TPCP1/1A or CGFE1)
LPG/NG
EFJLP1
is available for engineers who carry out electro fusion-jointing of Medium Density Polyethylene (MDPE) pipe-work, intended to convey either Liquefied Petroleum or Natural gas. The assessment is predominately practical; however there are a number of relevant knowledge questions to complete. There are no pre-requisites to taking the assessment, which can be completed by a well prepared engineer within ½ day.
