China Emergency Light – Practical Emergency Lighting Design Considerations
The primary task of practical emergency lighting design is to determine the requirements for a particular installation, taking into account building permit requirements. It is important to conduct site-specific risk assessments to ensure that all aspects of emergency lighting requirements within the building are met. The following steps cover only the basic design considerations for emergency lighting systems.

  Defining building standards

  Escape route, route exit and final exit (internal and external).

  Open area > 60 square meters.

  Areas of high-risk tasks (mobile machinery – thermal hazards, etc.)

  Enter the area, for example. Lifts, escalators, platforms.

  The total area of ​​disabled toilets and toilets is > 8 square meters.

  Alarm call points, fire fighting equipment and emergency areas.

  Occupation time (sleep risk, such as hospitals, hotels, etc.).

  Select system type

  Central battery / self-contained, duration, etc.

  Choose the right light source

  i e.LED or Fluorescent, select the type of fixture according to the desired position,

  note. BS 5266 specifies that the luminaires on the stairs must provide direct illumination on the stair steps. Regardless of size, there must be at least two luminaires in the escape cabin.

  Illumination design

  Escape routes

  maximum. Route width = 2 meters (if it is wider, it is considered as multiple)

  The lowest 1 lux. Add 0.5Lux to the centerline along the centerline to cover 50% of the route width.

  Open area

  Usually greater than 60 square meters or determined by risk assessment: 0.5 lux minimum (excluding the 0.5 meter belt around the fence).

  High-risk task area

  10% of normal illumination (not less than 15 lux)

  As mentioned above, emergency luminaires should be focused, for example

  Direction or level change (down risk)

  Close to the exit sign

  Near fire equipment

  Beyond the final exit

  note. «Close» means within 2 meters.

  Please note that this guide for China Emergency Light consolidation covers the basic requirements for emergency lighting design. You need to consider the building requirements and ensure that all risk assessments are carried out.
