Special &
In situ Tests

The purpose of ventilation systems is to ensure good air quality inside buildings and to remove smoke and heat in the event of fire.
Once a fire has started, it is essential that equipment operates correctly and that the procedures for safeguarding building occupants can thus be implemented appropriately.
In situ testing is a means of ensuring that resources will be effective when called upon.


Fire tests and in situ airflow measurements.

You can benefit from the expertise of the Fire Testing Centre in fire testing and in situ airflow measurement for appraisal of the performance of your ventilation and smoke-control systems in the field.

In situ tests are a select method for validating the characteristics and implementation of a system. They are an effective way of demonstrating the level of safety of works.

A special metrological system for heat and airflow measurement used in conjunction with the tests provides quantified results for objective appraisal of the performance level.

Controlled generation of smoke and heat enables observers to see, with their own eyes, representative flows from the fire simulated.

The smoke production techniques employed have to be adapted to the type of works and the smoke-control strategy (amount of smoke produced, heat emitted, smoke temperature, extent of smoke damage, etc.).

Testing is accompanied by expert appraisal of the results obtained to determine whether or not the ventilation system is fully effective.

A special application of in situ tests: safety drills.

All parties involved in safety must be prepared to tackle any event, and regular safety drills are an excellent means of ensuring their ability to react effectively.

For fire drills, a high degree of realism can be attained by generating smoke and heat. This puts participants in conditions very close to what they might have to confront.

For every fire safety drill, the scenario to be played out is defined beforehand, and drills are followed by analysis of all the results (conditions of the drill, interviews with participants, organization, setup, etc.).
