Guidelines on the functional recommendations and calculation methods for smoke and heat exhaust ventilation systems [3] ENSmoke and heat control systems — Part 2: For undated references, the latest edition of the referenced document including any amendments applies. It is essential that the air supply used for pressurization is never in danger of contamination by smoke.

Regulations

The declaration shall 12101-55 a certificate of conformity with, in addition to the information above, the following information: All doors within the pressurized space that cross the 12101- route from the accommodation area to the final exit door are open All doors between the pressurized stair and the final exit door are open 10 Pa The final exit door is crr The air release path from the accommodation area on the storey where the pressure difference is being measured is open A door to a floor other than the fire floor is open The doors between the accommodation area and the pressurized space are closed on all storeys Licensed copy: If tests are carried out where external conditions give rise to high wind and gusts, it may not be possible to achieve the design pressure differential.

This is determined by subtracting the total air leakage from the shaft with all doors closed from the total 12101–5 airflow rate under the most onerous air supply conditions see Clause If such ductwork penetrates a fire-resisting compartment, the ductwork shall be protected with suitable fire resisting material.

Materials handling equipment NOTE 2 The force that can be exerted to open a door will be limited by the friction between the shoes and the floor and Licensed copy: That the ventilation system has operated as required on all storeys should be ensured. Standardized thermostatic radiator valves contribute a lot to this fact. NOTE Where a depressurization system is being designed, QOther will include any losses through the external face of the construction.

Users are responsible for its correct application. The system shall be designed so that the stairwell and, where provided, the lift fr are kept clear of smoke. During firefighting operations it is necessary to open the door between the firefighting lobby and the accommodation to deal with a fully developed fire.

This Annex ZA covers kits for pressure differential systems as given in Clause 1 of this standard.

Smoke control using pressure differentials generally requires lower ventilation rates than b or c above but is limited to the protection of enclosed spaces adjacent to spaces being smoke logged in the event of a fire.

Typical leakage areas for the types of windows likely to be found in the pressurized space are given in Table 121015.

The corridor shall have pressurizing air supplied from a duct that is separate from the lobby and the stairwell supply. Requirement b above does not apply if there is a simple lobby between the staircase and the final exit door. Access and facilities for fire-fighting BS It is, however, essential that the 121015 shaft be kept clear of serious smoke contamination. This constitutes a fundamental difference between depressurization and smoke exhaust ventilation.

Fluid systems and components for general use This shall be achieved by providing separate pressurization of the firefighting vr shaft, lobby and stair.

Factory production control therefore brings together operational techniques and all measures allowing maintenance and control 21101-5 the conformity of the kit with its technical specifications. It is important that all the relevant airflow paths shall be identified and their effective flow areas evaluated.

For immediate assistance call us on: Mining and minerals Usually this fan duty will be less than that identified in 9. Consequently, the evacuation will occur during the early stages of fire development, and some 121101-5 leakage onto the stairway can be tolerated.
