FIRE SAFETY AWARENESS SEMINAR

• Mr. Bernard Lew

2
Introduction

• Manager, Emergency Preparedness Planning
  Division.
• Also Fire Prevention Officer, spearheading fire
  safety and prevention program in NUS.
• Role Plan and improve fire and life safety in
  NUS
• Main duties include coordinating , developing and
  implementing of policies, training and
  procedures.
• Staff 01 Technical Support Officer

3
Scope

• Why be concern about Fire Safety
• Fire Awareness Video
• Summary of Learning Points
• Fire Extinguisher Training
• Demo
• - Behind SOC 1 at Carpark 10

Why be concern about Fire Safety

• 1 out of every 3 people in this lecture theatre
  will have an experience with fire in their
  lifetime
• Lab and workshop areas provide unique
  circumstances for fire to start
• A small fire can grow very quickly and destroy
  years of work
• YOU can help to prevent fires before they start
• Know where the fire protection equipment and
  exits are before you need them -Have an escape
  plan
• Fire safety education gives you the training
  needed to make good choices

Summary of Learning Points

• Nature of Fire
• Fire is a chemical reaction known as combustion.
• Represented as Fire Tetrahedron Heat, Oxygen,
  fuel and chemical chain reaction
• Essence of process
• Fuel is heated and gives off vapor
• These vapors ignite and flames cause chain
  reaction to begin
• Chain reaction commences early in the burning
  process and as it increases its intensity, it
  accelerates the rate of combustion

7
Summary of Learning Points

• Causes of Fire
• Fire will occur with right mixture of three
  elements a source of fuel, oxygen and a source
  of ignition.
• Most work environments have many sources of
  combustible materials and sources of possible
  ignition.

8
Summary of Learning Points

• Fire Behaviour
• Fire must obey physical laws
• Where there is fire there is smoke
• It is the vapour that burns
• Oxygen increases fire intensity
• The principle of cooling, smothering and
  starving

9
Summary of Learning Points

• Fire Safety Management
• comprised of three elements
• Fire Prevention
• Fire Protection
• Fire Suppression
• Fire Prevention
• inspections, training, proper storage,
  housekeeping, reporting correcting hazards etc

10
Summary of Learning Points

• Fire Safety Management
• Fire Protection
• equipments and/or mechanisms such as fire alarm
  systems, emergency lightings, fire extinguishers,
  hosereels and sprinklers etc.

11
Summary of Learning Points

• Fire Safety Management
• Fire Suppression
• reducing the heat
• removing or reducing the oxygen
• removing the fuel
• Stopping the chemical chain reaction

FIRE EXTINGUISHER
13
Classes of Fire

• Class A
• Ordinary combustibles materials like wood, paper,
  cloth, furnishing, plastics and rubber
• Class B
• Flammable liquids, solvents, oils, paints,
  thinner and flammable gases
• Combustible liquids such as kerosene
• Class C
• Live electrical equipment like electrical mains,
  transformers and electrical appliances
  (extinguishing medium must be electrically
  non-conductive)
• Class D
• Combustible metals e.g. potassium, magnesium,
  titanium, sodium, lithium and zirconium

14
Types of Fire Extinguisher

• Water Extinguisher
• Used on Class A fires
• 6 or 9 litres, pressurized gas is air or nitrogen
• Operating pressure is 10 bar
• Use caution to avoid scattering lightweight
  materials with pressurized
• water and spreading the fire
• Dry Chemical (ABC)
• Effective for Class A, B and C fires
• 1 to 12 kg, pressurized gas is air or nitrogen
• Operating pressure is 7.5 to 15 bar
• Carbon Dioxide
• Used for Class B and C fires
• Filled with liquid CO2 to two-thirds, one-third
  is evaporated gas
• Comes with discharge horn to stop entrainment of
  air with CO2.

15
Rules for Fighting Fire
Just Remember the three As ACTIVATE the
building alarm or notify SCDF by calling 995. Or,
have someone else to do it for you. ASSIST any
persons in immediate danger, or those incapable
on their own, to exit the building, without risk
to yourself. Only after these two are
completed, should you ATTEMPT the extinguish the
fire
16
Fire Extinguisher Use
It is important to know the locations and the
types of fire extinguishers in your area prior to
actually using one. Fire extinguishers can be
heavy, so it is a good idea to practice by
picking up and holding an fire extinguisher to
get an idea of weight and feel. Take time to
read the operating instructions and warnings
found on the fire extinguishers. Not all fire
extinguishers look alike. Practice by releasing
the discharge horn or hose and aiming it at the
base of imagined fire. Do not release the pin or
squeeze the lever. This will break the fire
extinguisher seal and cause it to lose pressure.
