  1. Hi. Hopefully someone can give their thoughts on the following scenario: What is the maximum travel distance from a flat on the 3rd floor of a 4 storey building. The only route to exit the upper floor flat is via an open air walkway to a protected stairwell. This is also the normal means of entry/exit to this flat. I have measured the current travel distance and it is 21 meters (Flat door to the protected stairwell).
  2. Thanks for confirming my initial thoughts Tom. I did go ahead with the recommendation.
  3. Hi Anthony, No, there is no smoke ventilation within the main hall. There is a HVAC system to blow cold air into the main hall when the temperature gets too hot for the workers. This is activated manually.
  4. Good Morning. I have came across this Electrical Installation Container which is situated inside the main hall of a factory. The container has smoke detection and a FD60 fire door. However, there are 2 large extraction fans built into the roof. They just blow directly into the main hall and have no ducting attached. Should the fans be connected to ducting with fire dampers installed close to the fan? My concern is compartmentation of the container and the smoke/heat/products of combustion that would freely exit into the main hall through the 2 ventilation fans. The fans are mounted
