Fire

FIRE. Fires are something that only happen to other people. That is until an incident occurs involving fire. In general, this has devastating consequences because the company is in a state of complete shock. Production is halted, whether due to destruction, smoke damage or the intervention of the fire service. Staff are traumatised, whether by the evacuation or the potential risk they were exposed to.

 

A good means of protection is to create a climate of confidence about the company’s safety policy, whereby the doors used can ensure not only efficient intervention from the fire service but also good permanent use of the door, effective protection for people and work equipment, all at the lowest cost in the market.

 

General concept of fire-resisting doors

 

 

The door, providing the key to compartmentalisation

Compartmentalisation entails dividing the building up into areas, determined according to what requires protection.

 

Fire-resisting compartments imply that there are connections between them, which means that they need fire-resisting doors that operate permanently and can perform a fire-resisting role in the event of a one-off requirement.

 

=> This now makes the DOOR the key to compartmentalisation

 

 

Doors must fulfil 5 compartmentalisation objectives

 

1. Thermal insulation to prevent the adjacent compartment from catching fire.
     => Compartmentalise the building’s thermal load in order to keep the fire under control

 

2. A – Protection against cold smoke generated when the fire breaks out, due to incomplete combustion. It is highly toxic and fatal (causes 50% of deaths during fires), and enters into the machinery, electronic and IT equipment, making them unusable.
B – Protection against hot gases and total thermal insulation to avoid burns.
     => Protection and total thermal insulation between the compartment on fire and the others.

 

3. Protection and total thermal insulation between the compartment on fire and the others.
     => This means that the adjacent compartment can be used as temporary refuge or an escape route.

 

4. Fire stability and smoke tightness during the time required for the emergency services to intervene.
     => Facilitate the intervention of the fire and other emergency services.

 

5. Smoke tightness
     => Protect the environment against any pollution.

 

 

 

Introduction

 

When a fire breaks out, the structural components must do their job in spite of the impact of the fire. The structural elements’ stability must be guaranteed throughout the period required to evacuate the building. The walls which separate the various compartments in the structure must contain the spread of the fire. Evacuation must be carried out in an atmosphere where people can breathe and see where they are going. The operation of certain items of equipment, such as power or remote control cables, must be guaranteed in spite of the impact of the fire.

Harmonisation of European standards

Harmonising at EU level the methods for assessing the performance of structural products in terms of fire resistance needs Member States to use the same testing procedures and criteria for classifying them. This is exactly what has been done with the new system of fire resistance Euroclasses, which involves a change in the terminology used. For instance,

  • the letter E (from French term “Etanchéité au feu”) stands for Integrity

 

 

  • the letter I stands for Insulation 

     

     

     

     

 

This harmonisation has made it possible to compare European products with each other, no matter which country the fire test was carried out in. This means that official laboratories have had to adapt to the new test methodologies. On the other hand, each country can still choose the security level it imposes in its legislation, at its own discretion.

 

National regulations

 

They take into account:

  • E – tightness with regard to hot gases (UK, F, D, NL etc.)
  • I – insulation (limiting a rise of t° on the side facing the fire

I2: partial insulation of door set (the central section only) (F, D, I etc.)

I1: total insulation of door set, including edges and doorframe (B only)

 

IMPORTANT POINTS TO BEAR IN MIND WHEN THINKING OF A STRATEGY

 

They do NOT take into account:

 

  • Performances which exceed normal domestic use (example in Belgium: apartment landing door)
  • Protection against cold smoke (still so toxic to people and the cause of major damage) when fire breaks out
  • Thermal insulation of the edges (if not I1) in most countries
  • Sustainability of functionality and performance in every country.

Labelling – Identification

 

In some countries the following must be visibly identified:

 

  • Door manufacturer
  • Fire resistance performance (e.g. EI1 30) and/or
  • Fitter

In Belgium, for instance, Benor fire-resisting doors have:

 

  • a first Benor badge indicating the manufacturer’s Benor certification number and fire resistance performance, and
  • a second Benor badge indicating the fitter’s Benor certification number.

Transparency and confidence

 

With a concern for transparency in mind, Heinen mentions below useful links on standards. Heinen’s Benor certification is available in full on the UBATc website. It includes all the possible dimensions, types of fire-resisting glazing and fittings.

A modular solution based on Metal+

 

Heinen goes beyond the standards to ensure your safety by providing:

 

  • basic METAL+ Inside safety with performance levels tested for M7 and f8 after use
  • the widest range of fire-resisting doors on the market tested to the EI1 and EI2 specification
  • the option to integrate into the same METAL+ Inside structure a combination of protection features at a marginal cost, without diminishing performance in terms of the door’s use.
