| Ozone
Depletion |
|
| Due to the Ozone Depletion effect of Halons and
CFCs, an agreement has been reached at the United Nations
known as the Montreal Protocol,
to phase out Halon as a Fire Suppression agent: Lebanon has
signed this convention on March 31st, 1993.

| Halon
Alternative Agents |
|
| The most common Halon Alternative
Agents for systems' use are CO2, Nitrogen, Argon, FM200,
Halotron and others. Precise evaluation is required when replacing a Halon system with
any other agent type: in particular, CO2 is a non life-sustaining
agent should not be used in occupied
premises. Arrangements must be maid for any occupants to
reach a safe place prior to system discharge. Full
ventilation must be employed after any discharge of systems.
|
| Water Sprinklers |
|
| For large premises, Automatic Water
Sprinklers are still the most effective Fire Suppression system. These
could be either of the dry column type (either for areas of
very low temperature) , or the wet column type (more common
in this part of the world). In either case, a connection to the Fire Alarm system
must be maintained to trigger alarms as soon as the
sprinklers start operation.
|
| Autonomous Fire Suppression: |
|
| For closed and limited size rooms, an Autonomous
Fire Suppressions system must be installed incorporating
the correct fire-extinguishing agent capacity, with respect to the
expected area of protection and fire type.
A
connection
to the building fire alarm system must be maintained to trigger
alarm as soon as the system detects fire and starts
operation. |
