The TV and Film industry is unique with regards to the guidance to follow when ensuring that the correct fire safety arrangements are put in place. It may be that when filming inside, the guidance for Offices is the most suitable, however, when on location, it may be approximate to follow the guide for open air events, or even, based on your Fire Risk Assessment, a combination of the two. Similarly, when a film set is build outside, or in a remote location it may we'll have to adhere to elements of the Fire Safety in Construction guide. When considering a film set that is either under construction it is often at it most susceptible to fire. Timber or plywood construction is vulnerable to fire spread and due to it's temporary nature even more vulnerable, as more often than not the timber is not protected. There may also be an increased amount of solvents, packing and a variety of paint and cosmetic items which would not necessarily respond well to fire conditions.
For this reason when carrying out the initial Fire Risk Assessment, general fire precautions will vary from location to location and from film set to film set. Sometimes they will be very simple and other times much more complicated, depending on the risks involved at each stage of the set construction process and it's complexity.
