Occ Hazrads
LPG what is it?
Liquified Petroleum Gas
Occ Hazards
If powered by LPG what does the vehicle need on the number plate?
1 red diamond if powered by 1 cylinder
2 red diamonds if powered by 2 cylinders
Occ Hazards
Vehicles converted to LPG on or after 1993 need what?
Acceptable LPG compliance plate as required by as1425
Occ Hazards
Requirements of LPG storage containers
Filling capacity of containers is 80% to allow for expansion caused by increase in temperature. LPG containers are fitted with pressure relief valves. Domestic cylinders 1.75MPa. Automotive cylinders 2.55MPa
Occ Hazards
What is natural Gas?
Derrived from decomposed plant and animal material that been trapped underground. Extracted by drilling its used for heating, cooking, lighting and industrial purposes.
Occ Hazards
Natural Gas Characteristics
85%-95% methane
Colourless & odourless (odorant added)
Vapour density = 0.55 (Air = 1)
LEL = 5%
UEL = 15%
Occ Hazards
What is a BLEVE
Boiling Liquid Expanding Vapour Explosion
Allows tank to vent pressure when being heated
Occ Hazards
What is a BUND
Bunds are walls surrounding flammable liquid tanks designed to contain spills if it should occur.
Occ Hazards
Can firefighters go inside a BUND
NO
Occ Hazards
What is the most common type of tank fire?
RIM fire is most common with tank that have floating roof. Can be caused by lightning. Cool water must be applied to outside of tank. Excessive water on roof could cause roof to sink resulting in full surface fire.
Occ Hazards
Name the two types of foam delivery systems
Foam Pourers
Monitors
Fire Dynamics
Exothermic
Endothermic
Exothermic is when heat is given off as a result of the reaction. eg combustion of wood.
Endothermic reaction absorbs heat to make surroundings cooler. eg ice melting
Fire Dynamics
Heat is the measure of what?
Energy
Fire dynamics
What 4 ways can heat be transferred?
Conduction
Radiation
Convection
Direct Burning
Fire Dynamics
Define Convection
Transfer of heat through liquid or gas resulting in the displaced cooler air being drawn into the fire as the heat rises
Fire Dynamics
Define Conduction
When a heat source is in direct contact with a material it transfers energy directly into it
Fire Dynamics
Define Radiation
Energy is emitted in the form of electromagnetic waves which travel through the air
Fire Dynamics
What is a major factor in fire growth?
RADIATION
Fire Dynamics
Heat Transfer deteriorates conditions within a structure by what?
Increasing fire intensity
Increasing heat
Increasing fire gases and fire gas temps
Reducing visibility
Reducing survival chances of all persons
Compromising fire fighter safety
Fire Dynamics
What is the expansion rate of steam
1:1700 at 100C
1:3500 at 450C
TIC
Limitations of a TIC
Reflections
Depth perception
Stairs
Glass
TIC
What is thermal Inversion
A thermal representation of an object the changes from one shade to another by introducing a heat source in the background.
TIC
What does the green square with a green triangle inside it mean on a TIC screen?
It appears when 10% of the display has heat in excess of 130C
