IGEM/UP/19 Edition 2 Supplement 1 Guidance for gas engineers to the application of relevant sections of IGEM/UP/19 in catering establishments
Date issued: 21 October 2024

This Industry Standard Update provides an overview of the recently published industry standard IGEM/UP/19 Edition 2 Supplement 1 Guidance for gas engineers to the application of relevant sections of IGEM/UP/19 in catering establishments.

Introduction
In August 2024 the new IGEM/UP/19 Edition 2 Supplement 1 Guidance for gas engineers to the application of relevant sections of IGEM/UP/19 in catering establishments (Communication 1876)⁽¹⁾ was published. This revised publication supersedes IGEM/IG/2 Guidance for gas engineers to the application of relevant sections of IGEM/UP/19 in catering establishments (Communication 1772)⁽²⁾, which has now been withdrawn.

The revision to this standard comes into effect immediately.

Scope
IGEM/UP/19 Edition 2 Supplement 1 gives guidance for gas engineers on how to apply IGEM/UP/19 Edition 2 Design and application of interlock devices and associated systems used with gas appliance installations in commercial catering establishments⁽³⁾. All information contained in Supplement 1 can be found in the full version of IGEM/UP/19 Edition 2.

General
Significant and minor amendments have been made throughout the standard and the main details are as follows.

Section 4.7.2 now states that testing on a new, partially new or existing installation needs to be performed with appliances and burners operating on maximum cooking load conditions and without any utensils in place. Ventilation systems need to be operating normally with all filters and baffles in place.

Where variable speed systems (VSS) systems are installed, the tests need to be performed at the lowest setting, as per 4.7.3. If the VSS interlocks are installed in conjunction with sensors, the test needs to be carried out in all operating modes, ensuring that the air quality is maintained throughout the range of conditions.

There have been considerable amendments to 5.1 and 5.2, and references to Type A and Type B appliances have been removed. Section 5.2 now directs that, where practicable, users need to be advised that the frequency of servicing and testing of ventilation systems is to be based on the manufacturer’s instructions and the use of catering equipment. However, at least yearly would be a reasonable minimum frequency: this also applies to the gas installation.

There are small changes to the illustrations and flow charts and a slight amendment to give a carbon dioxide detector fitted at approximately 2 meters from the floor. Figures 2 and 3 (risk assessment flowcharts) deal with NEW or EXISTING installations and have slight amendments. They replace the previous versions.

An additional note in 7.1 provides details of the actions required by the responsible person in the kitchen when a gas detection system alarm is triggered.
