- Escape routes 
To the front and rear of the installation, and between two 
installations sited opposite each other, an escape route at 
least 0.5 m wide and 2 m high must be present over the 
entire length of the installation. The width of the escape 
route is measured from the part of the installation that 
projects furthest. The escape route must be completely 
clear and as far as possible in a straight line. 
 
The installation may be set up with the back against 
a wall. In that case there will be no clear area or 
escape route at the rear or sides. 
 
- Entrances 
Entrances to the switchroom and escape routes must be 
kept clear at all times. 
 
Entrances must be provided at suitable places and must 
be at least width of panel plus 0.2 m wide and height of 
panel (without arc channel) plus 0.2 m high. For details of 
width and height of panel, see chapter 2.4.3. Entrances 
must be accessible via the escape routes. It must be 
possible to open access doors outwards without the use 
of aids. 
- Storage of materials 
Items not connected with the installation must not be 
stored in the switch room. Flammable materials, 
combustible gases and dangerous chemicals must not be 
stored. 
- Availability of extinguishers 
Suitable extinguishers must be present in and around the 
switch room. Obtain expert advice (fire brigade) on the 
best choice and location of the extinguishers. 
 
1.3.3  What to do in the event of a fire 
In the event of a fire in the switch room, proceed as 
follows: 
  Evacuate all personnel from the switch room 
  Call the fire brigade. 
  Notify specialists who can switch off the installation 
completely, i.e. including: 
  Incoming cables; 
  Low-voltage cables; 
  Feedback from the low-voltage side; 
  Any other power sources. 
  Follow local fire instructions. 
 
NEVER ATTEMPT TO EXTINGUISH THE FIRE 
BEFORE THE INSTALLATION IS COMPLETELY 
DEAD I.E. ISOLATED FROM THE SUPPLY. 
NEVER extinguish with a water jet. 
Make sure that no water flows into the 
installation. 
Keep well clear of the installation while the fire is 
extinguished in the area around the installation.  
Even using non-conducting extinguishing 
materials, a voltage may pass through the 
extinguishing equipment. 
 
Putting the fire out: 
  If possible, leave extinguishing the fire to the fire 
brigade. 
  Use non-conducting extinguishing materials. 
  If necessary, use extinguishers in the area around the 
installation. Never attempt to extinguish the 
installation itself, even if it appears to be dead.
