Emergency lighting & escape signage
Emergency and escape lighting is a requirement (Part B1, Section 6.36 of the Building regulations, Table 9) for most if not all public buildings and places of employment.
In its simplest form, it provides people with enough light to see an escape route and use it easily even if it contains hazards such as stairs, steps or other obstacles that could cause injury. It must be able to do this for up to 3 hours when all normal sources of power have failed. It may also be needed in public open areas (to prevent panic) and high risk task areas.
The brief sounds easy but to engineer a system that meets the standard and is cost effective in operation and maintenance requires design qualifications and experience. Historically the task was often carried out by the electrical contractor and there are many who are amply qualified to do this but increasingly the task is packaged with the fire protection system. We believe this is a wise move by consultants as they know the system will have a better chance of being maintained properly throughout its life cycle.
