Large Dry Chemical (LDC) System
• This large Dry Chemical (ANSUL) is the main fire extinguisher on the
platform. On production platform, the system is usually designed to
extinguish should any fire occurs at wellhead and production header
area, test separator area and at slop area. The planned maintenance
of this safety equipment is scheduled one month, 6 month and yearly.
Practical Tip
• Although the job lists has been established, the next most importance
step for supervisor is to ensure that the jobs are done correctly and
the procedures are precisely followed as written in the job list.

Portable Fire Extinguisher (PFE)
Portable Fire Extinguisher.
• Considering that economics become an important factor in the
larger capacity fire extinguishers; consequently portable fire
extinguisher becomes a favorite choice. It is very popular and
widely used in the world from large industries to household. The
units are designed for personal use. Dry chemical cartridge
operated hand portable fire extinguishers are available in size
ranging from 5 - 30 pounds. The units are classified in to class A, B
and C depending on the agent used. Specialized units are also
available for class D fires.
• Maintenance of portable fire extinguisher is scheduled monthly and
yearly. Detail work scopes are described in the SAP.
7
Portable Fire Extinguisher (PFE)
There are two main types of portable fire extinguishers :
a. Stored pressure, where the expellant is stored in the same
chamber as the firefighting agent itself. Depending on the
agent used, different propellants are used. With dry
chemical extinguishers, nitrogen is typically used; water
and foam extinguishers typically use air. Stored pressure
fire extinguishers are the most common type
b. Cartridge-operated, where the expellant gas in a separate
cartridge that is punctured prior to discharge, exposing the
propellant to the extinguishing agent. This type has the
advantage of simple and prompt recharge, allowing an
operator to discharge the extinguisher, recharge it, and
return to the fire in a reasonable amount of time. Unlike
stored pressure types, these extinguishers utilize
compressed carbon dioxide instead of nitrogen.
8
Portable Fire Extinguisher (PFE)
Fire extinguishers are classified according to
their capacity to fight specific kinds of fire.
1. Class A: For fires in ordinary combustible
materials such as wood and paper where
it needs a quenching, cooling effect.
2. Class B: For flammable liquid and gas
fires such as oil, gasoline, paint, and
grease where it needs oxygen exclusion
or flame interruption.
3. Class C: For fires involving electrical
wiring and equipment where it needs non
conductive extinguishing agent
4. Class D: For fires in combustible metals
such as sodium, magnesium, and
potassium.

BREATHING APPARATUS
There are two basic type of respirators :
1. Air-Purifying Respirators - it is exactly what the name
implies. These apparatus purify and filter air before we
breathe it in. They do not supply air or oxygen, but they can
only purify air in the surrounding atmosphere. There are
different air-purifying filters for different hazards.
2. Supplied Air Respirators - it is exactly what the name
implies. It supply air, the air comes from a cylinder or
compressor. These respirator provide the best protection
against many hazards, but they have their limitations. With
self-contained breathing apparatus, there are problem with
weight, whereas with airline unit the hose can get tangled.
There are also concerned with the quality of air stored in
cylinder or supplied by compressor. It may not be breathable
air we need.
