This Technical Report applies to SHEVS when installed in a building. This Technical Report specifies the ability of the system to meet the required performances of the SHEVS as specified by the design of the system. This Technical Report is to help to translate the detailed engineering plan into an installed system, but it does not state how the design is made. This Technical Report also covers requirements for components and compatibility between components to ensure that the requirements on the installed system will be met. This Technical report includes requirements for the assembly, installation, commissioning, function testing, maintenance, periodic servicing and routine testing of SHEVS.

Introduction

Smoke and heat exhaust ventilation systems (SHEVS) create a smoke free layer above the floor by removing

smoke and thus improve the conditions for the safe escape and/or rescue of people and animals. It

contributes to the protection of property and permits the fire to be fought while still in its early stages. They

also exhaust hot gases released by a fire in the developing stage.

The use of smoke and heat exhaust ventilation systems to create smoke free areas beneath a buoyant smoke

layer has become widespread. Their value in assisting in the evacuation of people from construction works,

reducing fire damage and financial loss by preventing smoke logging, facilitating fire fighting, reducing roof

temperatures and retarding the lateral spread of fire is firmly established. For these benefits to be obtained it

is essential that smoke and heat exhaust ventilators operate fully and reliably whenever called upon to do so

during their installed life. A heat and smoke exhaust ventilation system is a scheme of safety equipment

intended to perform a positive role in a fire emergency.

Components for smoke and heat exhaust ventilation systems should be installed as part of a properly

designed smoke and heat exhaust ventilation system.
Smoke and heat exhaust ventilation systems help to:
 keep the escape and access routes free from smoke;
 facilitate fire fighting operations by creating a smoke free layer;
 delay and/or prevent flashover and thus full development of the fire;
 protect equipment and furnishings;
 reduce thermal effects on structural components during a fire;
 reduce damages caused by thermal decomposition products and hot gases.

A powered smoke exhaust system can also be used for the realisation of the following purposes:

 creation of a negative pressure differential facing the direction of escape for the prevention of the spread

of smoke;
 local dilution of smoke within occupied zones.

Natural smoke and heat exhaust ventilators are devices fitted into the roof and/or upper walls of a construction

works to allow smoke and fire gases to be exhausted from the construction works when driven by thermal

buoyancy inherent in those gases. It is essential that they are able to open, and/or to remain open in the event

of a fire and to fulfil their function even when climatic and weather conditions are unfavourable.

Depending on the building geometry and siting of the building with regard to neighbouring buildings, and

design criteria, natural smoke and heat exhaust ventilators can be used instead of powered smoke and heat

ventilators.

This Technical Report sets down the testing requirements for the system when installed to ensure that it

operates in a safe and reliable manner. Commissioning, periodic maintenance and servicing requirements are

stated as well as the users’ responsibilities for ensuring that the system is always for use in case of fire.

Components of the SHEVS should be designed or chosen to meet the specific performance requirement of

the system.

Without proper installation of all of its components, the SHEVS could not operate correctly nor meet the

performance targets for which it has been designed.

Commissioning is necessary to check the SHEVS operates in accordance with its design. The system has to

be permanently available for operation. This can only be achieved when checked and maintained.

1 Scope

This Technical Report applies to SHEVS when installed in a building. This Technical Report specifies the

ability of the system to meet the required performances of the SHEVS as specified by the design of the

system. This Technical Report is to help to translate the detailed engineering plan into an installed system, but

it does not state how the design is made. This Technical Report also covers requirements for components and

compatibility between components to ensure that the requirements on the installed system will be met. This

Technical report includes requirements for the assembly, installation, commissioning, function testing,

maintenance, periodic servicing and routine testing of SHEVS.
