scope:

This Standard provides the minimum requirements for combustion systems in respect of safety in start-up, operation and shut-down of gas-fired process plant. It does not provide a complete specification for burners, plant and control equipment.

This Standard applies to the use of gas in plant in industrial and commercial premises and nothing in this Standard implies any requirement for burners or appliances for other applications, for example for gas turbines (see IGEM/UP/9) or for appliances constructed to recognised European standards such as hot water/steam boilers and air heaters for space heating.

This Standard applies to relevant plant using Natural Gas (NG) and Liquefied Petroleum Gas (LPG). It may also be applied for other gases and fuels where no other guidance is available, provided due allowance is made for the different combustion qualities and fuel characteristics. Further advice on dual fuel and multi-fuel firing is given in Section 10.

It is recognised that, for specialised gas-fired processes, it is permissible to use procedures which differ from those given in this Standard but which, nevertheless, comply with the intent. Similarly, new systems or procedures resulting from advances in technology may be applied to give equal or improved safety. It is not intended that this Standard prohibit the development or use of such systems, but any departure from this Standard is not recommended except when on the basis of sound engineering judgement and practice, experience, and when subject to a risk assessment.

This Standard does not apply to:

• small industrial plant and appliances of heat input not exceeding 7.5 kW (25000 Btu/h) under constant manual supervision, for example, soldering irons, small lead pots, Bunsen burners, gas rings, small open-ended furnaces, etc.

• burners, appliances or plant covered by specific manufacturing standards, for example BS 5885, BS 5990 and BS 5978. However, they do include application requirements for such burners when applied to process plant

• plant covered by specific British or European manufacturing standards, for example, BS EN 676. However, they do include the application of such plant

• heating plant such as boilers and space heaters supplied complete with matched burners

• gas turbines, for which reference should be made to IGEM/UP/9

• spark ignition and dual-fuel engines, for which reference should be made to IGEM/UP/3

• the distribution and use of protective atmosphere gases, for which reference should be made to BS EN 746-3. However, for atmosphere gas generator burner control and safety systems, this Standard applies.

This Standard assumes that plant is designed and installed in accordance with sound engineering practice and having due regard any relevant legislation such as, but not limited to, GS(I&U)R and the Health and Safety at Work Act (HSWA).

This Standard applies to both high-temperature plant (defined as having a normal working temperature sufficient to ignite the fuel, that is above 750°C at the working chamber walls) and low-temperature plant (defined as having a normal working temperature at or below 750°C). High-temperature plant will also operate in the low-temperature mode at some time in its operation and this has to be taken into account when assessing safety issues.

This Standard applies to new plant and it is not the intention to apply any requirements retrospectively. However, if existing plant is being upgraded, it is recommended that the intent of this Standard is to be followed as far as possible. A risk assessment is to be made whenever any changes are proposed for any plant (see IGEM/G/7).

All pressures are gauge pressures unless otherwise stated.

All heat inputs are net heat inputs unless otherwise stated.

Italicised text is informative and does not represent formal requirements.

Appendices are informative but can represent formal requirements if referred to via the prescriptive terms "should", "shall" or "must".
