8 Basic Fire Safety Knowledge
8.1 The Fire Triangle
There are 3 elements that can cause a fire:
• Fuel: Any kind of combustible material.
• Heat: High-temperature source responsible for ignition of fire, such as sparks from hot welding
and cutting work, short circuits, flares, cigarettes, lightning, etc.
• Oxygen: The air contains 21% of oxygen, which is enough to trigger a fire.
Figure 8: Fire Triangle
8.2 Classes of Fire
Classification Fire Risk
Solid combustible materials (i.e., wood, paper, cloth, cotton,
rubber, plastic)
Flammable liquids and gases (i.e., oil, propane, grease)
Live electrical equipment (i.e., short circuiting equipment)
Combustible metals (i.e., Magnesium, Aluminium)
Cooking oils and fats

8.3 Fire Extinguisher Types
Figure 9: Types of Fire Extinguishers
8.4 Fire Extinguisher Operating Instructions
• Draw – Draw out the hose
• Pull – Pull out the safety pin
• Squeeze – Squeeze the handle and hold the hose firmly
• Sweep – Carefully move 2-4 meters closer on the windward direction. Sweep the hose from
side to side at the base of the fire until it is extinguished.
8.5 Portable Fire Extinguisher Inspection
• Portable fire extinguishers have a pressure gauge with a red section and a green section. The
needle should be pointing in the green area (see picture below) which indicates it is in the range
for optimal operation. If the needle is in the red zone (Recharge or Overcharged), it indicates
that the pressure is small and cannot be ejected.
Operable Inoperable
Figure 10: Fire Extinguisher Pressure Gauge
• Safety pin and tamper seal: Inspect that the locking/safety pin and tamper seal are in
place and unbroken which is a proof that the fire extinguisher has not been tampered
with or used. This is to ensure that the fire extinguisher is working efficiently and can
be used effectively in the case of a fire emergency.

9 Safety Signs in the Workplace
Safety signs are a type of sign with internationally agreed and globally used texts and symbols intended
to provide safety information, warn of workplace hazards, prohibit actions, or instruct employees or vis-
itors to stay out of hazardous areas and strictly follow any recommended precautions. There are many
different types of safety signs, all of which have their own different shapes, sizes, colors, supplementary
text or symbol displays.
Article 2 of the Notification of Department of Labour Protection and Welfare “Warning sign, the sign
about safety, industrial hygiene and environment at workplace, the statement of right and responsibility
of employer and employee B.E. 2554 (2011)” specifies that “the employer shall attach the warning sign
and the sign about safety, industrial hygiene and environment at workplace which shall be appropriated
in accordance with the character and condition of work and must obviously be seen at the workplace”.
Safety Signs are used to:
• Indicate safe operating conditions.
• Remind unauthorised personnel to proceed with caution.
• Provide information about rules and requirements for workplace safety
• Prohibit unauthorised personnel from entering or indicate that an action is prohibited.
• Indicate where an activity is being conducted and how to proceed.
• Advise others to stay out of hazardous construction areas.
