Among other methods, fire sectorisation may be carried out through:
- Fire curtains: mobile textile systems designed to guarantee the integrity, isolation and low radiation in any case, as well as non-penetration of smoke.
- Smoke control barriers: designed to channel, contain and/or prevent the spread of gases generated in the case of fire.
A fire sector is a space or area of a building which is compartmentalised from the rest through fire resistant construction elements for division.
Sectorisation of fires keeps fire and smoke under control, preventing it from quickly expanding through the rest of the building. Risks are minimised in fire extinguishing tasks, allowing greater visibility and ease in accessing the affected area, avoiding the transmission of harmful smoke particles, reducing major structural damage, reducing subsequent costs, and allowing evacuation under the best conditions.
These are fixed or mobile textile screens, designed to channel, contain and/or prevent the spread of gases generated in case of fire. Their main purpose is to contain gases in areas called smoke deposits, or to move them to specific evacuation areas.
Take the following into account:
- Maximum dimensions certified by regulation EXAP EN 15269-11.
- Installation during the fire resistance test in accordance with regulation EN 1634-1 (resistance capacity against direct attack by fire on structural elements (box and lateral guides)).
- Controlled, safe closing by gravity certified in accordance with regulation EN 14600.
- Need to incorporate a system with an Emergency Function in case anyone is trapped in the seat of the fire.
It is measured based on the following parameters (or their combination):
- R – Load bearing. The capacity for mechanical resistance of the construction element, without losing its structural properties.
- E – Integrity. Capacity of the construction element to prevent the passage of fire and hot gases to an area not affected by the fire.
- I – Insulation. Capacity of the construction element to prevent the temperature increasing on the face which is not directly exposed to the fire.
Generally, this classification is followed by a number which indicates the time for which these parameters are fulfilled.
- EN 1634-1 FIRE RESISTANCE TEST: Specifies the test method to follow to determine the fire resistance of the fire curtains as a fire compartmentalisation system.
- EN 13501-2 FIRE RESISTANCE CLASSIFICATION: Defines a harmonised procedure for the classification of fire resistance of fire curtains.
- EXAP EN 15269-11 EXTENSION OF APPLICATION OF TEST RESULTS: Extends the tested dimensions of the fire curtains during the Fire Resistance Test in accordance with regulation EN 1634-1 to larger dimensions.
- EN 14600 DURABILITY AND AUTOMATIC CLOSING TEST: Compliance requirements and methods necessary to demonstrate the capacity of a fire curtain to cover the whole cycle of the system.
- TECHNICAL SUITABILITY REPORT: Verifies that all components and characteristics of the fire curtains fulfil the function required as a complex, non-conventional fire compartmentalisation system.
- APPLUS+ FIRE SAFETY CERTIFICATION: Voluntary certification to ensure that the quality and performance of the fire curtains evaluated during the tests remain constant over time through periodic factory controls.
