In order to ensure safety to chemical industry
personnel and minimize harm, the companies
plan emergency escape routes in their
facilities.
This presentation introduces the reader to the
emergency escape route planning, indication
and correct maintenance to ensure its use in
case of need.

Context
 In industry, undesirable events can
occur and endanger the lives of
those present on site:
 Incidents
 Failures
 Fires
 Explosions
 Main dangers in the event of an
emergency:
 Fire, smoke, gas or water leaks
 Unusable escape routes
 Disorientation in the dark

What is an Emergency Escape Route?
 A path is considered an emergency escape route if it is:
 The shortest path which can be taken to safely leave the
plants/buildings from any location and reach an open space.
 A means of escape is composed of the following elements:
 Escape route
 Premises’ exits
 Corridors
 Stairways

Emergency Escape Routes – Good Practices (1)
 Emergency evacuation plans have to be displayed at
strategic locations and should be visible and
understandable.
Source: Suva

10
 The escape routes are clearly
indicated and equipped with specific
signs.
 The escape routes (corridors, doors,
etc.) are free of obstacles.
 The escape routes can be used
without any risk.
 The exit doors are keyless and open
in the direction of the escape route.

11
 One is able to escape from any basements or storeys in
the event of a fire.
 The lighting of the escape routes
is in good condition.
 In case of a power failure, the
escape routes are always
easily recognizable
(e.g. emergency lighting,
phosphorescent signs).

Design of Emergency
Escape Routes

13
Dimensioning of Emergency Escape Routes
 When dimensioning emergency escape routes, several
parameters have to be considered:
 Number of occupants
 Number of storeys
 Type of construction
 Situation
 Surface
 Allocation of the buildings,
installations and firebreak
compartments
Measuring the shortest distances with an arc

14
 If the emergency escape
routes give access to:
 Only one stairway, the gross
floor area should not be larger
than 600 m2.
 Several stairways, the gross
floor area should not be larger
than 900 m2.
 The stairways should be as
far as possible from each
other to offer independent
escape directions.
Source: Based on ECAP

15
 Stairways and staircases:
 The minimum width for stairways should be 1.2 m.
 Staircases should be firebreak compartments (resisting at least a
fire of one hour).
 Corridors:
 The minimum width for corridors should be 1.2 m.
 Corridors can be firebreak compartments.
 Doors:
 Doors should open in the direction of the escape route.
 The exit doors can be opened without external help (e.g. key) and
also from the outside (for rescue teams).
 Each door should have an average clearance of 0.9 m.

16
Design of Emergency Escape Routes
 The design of the escape routes is approved by the
competent authority and recorded.
 If the emergency escape routes are to be modified (e.g.
transformation of the building), the competent authorities
have to be consulted.

17

18
Organization, Training and Behaviour
 The use of the emergency
escape routes is included in the
training programme of the
emergency response plan.
 Short-term employees and third
parties intervening on site are
informed of the rules to observe
in the event of an emergency
evacuation.

19
Organization, Training and Behaviour
 A designated person periodically
checks the escape routes and
their safety features.
 Superiors monitor compliance
with the rules, correct non-
compliance and encourage
workforce to ensure safety:
 Obstacle-free escape routes
 Access to the exit doors clearly
indicated

Key messages
 A path is considered an emergency escape route if it is the
shortest path which can be taken to safely leave the
plants/buildings from any location and reach an open
space.
 A designated person periodically checks the escape routes
and their safety features.
 If the emergency escape routes are to be modified (e.g.
transformation of the building), the competent authorities
have to be consulted and the workers informed.
