Question 1

What are the 3 Golden rules to follow when applying foam?

Answer 1

(1) Do not begin to apply foam unless you have enough to extinguish the fire or cover the fuel spill.
(2) Point branch away from fire until good foam is being produced.
(3) You cannot mix different foam concentrates.

Question 2

List 3 hazards/considerations when using CAFS at a structure fire.

Answer 2

(1) CAFS hose lines have a build up of pressure when the branch is closed, this causes a larger jet reaction than a standard hose
(2) Slug flow – When the proportion of foam, air and water is wrong. It will cause the finished foam to “shudder” or “pulsate” as it is exiting the branch. if you experience slug flow, notify the motor driver so that they can adjust the settings at the pump.
(3) A CAFS line must never be used for an internal attack, that is because the mixture does not contain enough water to cool the hot fire gasses. This will result in dangerous conditions that goes against our SOG’s for internal firefighting.

Question 3

List 5 actions to take when combatting a natural gas leak with no fire involved.

Answer 3

• Structural PPE and SCBA
• Evacuate all persons from the immediate area
• Remove all sources of ignition

B - Building
S - Smoke
A - Air Track
H - Heat
F - Flame

Question 6

What techniques enable us to control the interior environment during a structure fire?

Answer 6

Gas cooling and hose stream techniques enable us to control the interior environment during a structure fire as we strive to access and extinguish the fire and then perform search & rescue.
SHORT PULSE: is used as soon as there is hot fire gases above (or around) a hose crew. It is also used to dilute and cool gases that may present a FGI risk.
LONG PULSE: should always be used aggressively when there are large amounts of fire gases and/or compartment size requires greater penetration.

Question 7

List 2 common hose laying techniques that can be used by firefighters?

Answer 7

Technique (1) - S LAY
If it’s a medium or larger building with chance of structural collapse, hose is positioned outside collapse zone by MD.

Traditional “S” lay
2 x lengths of 38mm hose flaked in hose tray

Run out by Motor Driver

Second length near entry point
Easier to pull hose into structure
Slowly charged to stop knots in the hose
No2 untangle hose if needed

Technique (2) - Cleveland Load
Been in service since 2011.

American method - Cleveland load (coil lay)

Fast, simple used in tight areas where hard to lay hose.

Used at:
high rise – stairwells
Structure fires that cannot be accessed directly from the footpath
Investigating AFA, gaols where not immediately need to lay hose
Bushfires property protection
Bush and grass fires in difficult to access locations

Easier to manage the hose and quicker to deploy

Question 21

List and describe how a structure fire will burn within one of two burning regimes.

Answer 21

• Fuel Controlled - In this initial phase of fire development the fire grows as a direct function of the fuel itself with little or no influence from the compartment environment. ie. The size, shape or number of openings. If we continue to add fuel the fire will grow in size. If we remove fuel, the fire will decrease in size. Therefore fires with more than enough air for combustion are said to be Fuel Controlled.
• Fires begin as fuel-controlled, and at some point within the fire growth, so much fuel vapour is produced that the Heat Release Rate (HRR) and growth become limited by the availability of oxygen. The fire then becomes a ventilation-controlled fire.
• Ventilation Controlled - Most structure fires will reach a stage where fire development and the Heat Release Rate (HRR) is now dictated by the availability of oxygen. This occurs during a fully developed fire when the fire is pyrolyzing more fuel than can be burnt with the available oxygen in the compartment. It will also occur prior to this if the enclosure has insufficient openings. Simply put, fire growth (and HRR) is limited by the available air (O2) supply.

Question 22

List the search priorities in multi storey buildings

Answer 22

(2) Command – having a strong command presence from the outset of an incident.
(3) Situation evaluation – continuously collecting and evaluating information about the incident in order to determine critical factors.
(4) Incident action planning – having an incident action plan that addresses the critical factors.
(5) Incident communications – having efficient and effective incident communications to describe the flow of information within and out of the incident.
(6) Incident structure – having an incident structure that is flexible and able to be scaled to meet the incident size and needs, with the ability to delegate functions and responsibilities as span of control is reached.
(7) Review and revision – once in operation, reviewing and revising the strategy and plan, to keep it current with the changing needs of the incident.
(8) Escalation and de-escalation – as additional officers or an Incident Management Team arrive, scaling up the strategic management level of the incident; and scaling down as operations conclude.

Question 26

At every incident there must be a steady, adequate, and timely stream of resources. Who is the only person to deploy resources at an incident?

(2) Full rehabilitation – Crew is released and moves to the rehabilitation area. Once there, they are accountable to a Rehabilitation Officer.

Question 29

List and describe the three incident phases.

Answer 29

(1) Life at risk phase – there are savable human lives. Incident is uncontrolled and requires rapid actions to control risks to lives. A higher level of risk may be acceptable.
(2) Expanding phase – incident is likely to expand beyond accepted limits. Incident is uncontrolled and requires rapid actions to control risks to lives and property. Some level of risk may be acceptable.
(3) Contained phase – there are sufficient resources to contain incident within a defined area. There is no life at risk, or lives and property are already lost. Risk must be minimised as much as practicable.

There are two control measures when dealing with live power at an incident. List and describe them.

Answer 53

(1) Turning off power
• Involves turning off the main switch, removing fuses and switching off circuit breakers at the switchboard. This removes internal power. Note that the consumer main is still live and poses real danger
(2) Isolating Power
• Is the best way to control an electrical hazard but this can only be done by an energy authority. They disconnect power from the network to the site.

Question 54

Firefighters can ‘turn off’ a solar power system to stop electricity feeding into the structure’s circuits or back to the electricity network if configured to do so. State the recommended procedure.

Answer 54

(1) On-site consultation: determine whether it is appropriate to turn solar power system off and how best to do so.
(2) Assume switchboard is live: Don electrical safety gloves then over-gloves. Have your helmet visor down and look away.
(3) Follow the shutdown procedure: This may be on or near the switchboard or inverter. If not found, turn off the inverter main switch then turn off the solar panel main switch.
(4) Consider if benefits outweigh risks: Restrict work as far as reasonably practical to that required to protect life or prevent dangerous expansion of the incident.
(5) Isolate the power: If required, have the owner/occupier contact their electrician to isolate the power.

Question 55

When a battery energy storage system is present at a residence, there should be an indicator to alert you to this. What is an example of an indicator, located outside the switchboard.

(3) Knock-down any fire using copious amounts of water.
(4) Cool the battery with a cooling stream of water.
(5) Submerge the device in a suitable container of water if safe to do so. Use a tool such as a long-handled shovel to move the device.
(6) If unable to submerge the device, continue cooling and conduct thermal checks every 15 minutes until ambient temperature is maintained for 60 minutes.
(7) Ensure that all cells are accounted for by searching the area around the device.
(8) Notify FireCOM that the incident involves a lithium-ion device. FireCOM will send a notification to FIRU.

Question 57

If solar panels, or the attached isolators, are on fire, in addition to the considerations with turning off an alternative power source what actions should firefighters take?

Answer 57

• Conduct firefighting from the ground or an aerial appliance. Do not get onto the roof to extinguish the fire. Do not put a ladder against the roof as the gutter may be electrified.
• Extinguish the fire with a spray nozzle, using a pulse spray in a dispersed pattern
• If the solar panel is at ground level, consider using CO2 to extinguish the fire, ensuring that there is at least 250 mm air gap between the CO2 extinguisher nozzle and any electrified components.
• NSW Fair Trading notification form to be completed at completion of incident

Question 58

If you are the first arriving crew, you must send an initial radio report as well as pressing Code 3 on your MDT. FireCOM needs this information for what reasons?

Answer 58

• It confirms to FireCOM you are at the correct address.
• It allows FireCOM to pre-empt your need for extra assistance.
• It allows FireCOM to notify specialist support and external agencies such as police, ambulance and energy companies.
• It is also a requirement under SOG 1.5 – Incident Communications

Question 61

Property protection is the act of protecting property from the impact of a wildfire. At a major wildfire, FRNSW crews generally engage in property protection roles. We generally have 3 strategies for carrying out property protection. Name and describe them.

Answer 61

Line Defence - protect the perimeter of a property until resources are sufficient for an offensive attack. It involves preventing the approaching line of fire from closely approaching the property. A line defence is used when conditions would normally allow an offensive attack but there are not enough units to mount an offensive attack in time. It involves preventing the approaching line of fire from closely approaching the property.
Ember Defence - firefighter focus is on extinguishing embers and spot fires in and around structures. It is used when the approaching line of fire is too intense to be supressed by offensive means. An ember defence is used when the approaching line of fire is too intense to be
suppressed by offensive means and is producing significant ember attack.
It involves extinguishing small fires that occur in and around buildings, when and as they occur.
Firefighters operate from safe positions behind suitable shielding from the main fire front and pull back to safer refuge if needed.
Backstop Defence - firefighters retreat while fire front passes and move back in to save savable structures afterwards. A backstop defence is used when there is no safe defensible space around buildings and/or the approaching fire is so intense that firefighters cannot safely protect the
buildings during the impact of the fire. Firefighters withdraw temporarily a short distance away to a suitable safe refuge, with the intention of coming back after the fire front passes. After the main fire front subsides, they move forward to put out the property on fire. This type of defence is used when firefighters have run out of all other options.

Question 62

List all the hazards and risks at incidents involving Lithium-ion batteries in small devices.

Answer 62

Question 64

When an LPG container is involved in fire, what area of the container is considered most crucial and a high priority area for cooling?

Answer 64

The container’s vapour space (area above the liquid) is most crucial and is to be considered a high priority area for cooling.

Question 65

When conducting ventilation with a fan, the fan should be set back approximately how far from the door.

Answer 65

The fan should be set back approximately the height of the door.

Answer 112

All radio messages must follow the Conditions, Actions, Needs (CAN) format, to succinctly describe the conditions present, the actions being taken, and any needs. The incident management system stresses that communications must follow the incident structure, with communication only occurring up or down one level.

Question 113

There are three strategies used during bushfires operations. Name and describe them.

Answer 113

(1) Offensive Strategy - FRNSW initiates offensive operations at bushfires. The factors that determine the success of an offensive operation are the location and size of the attack and support for the attacking crew.
Direct attack is at the fire edge to extinguish or control the flames directly, eg applying water, smothering with foam or soil, beating, or starving of fuel by raking the fuel into the fire. This then becomes the established control line.
Parallel attack is used to control the intensity of the fire. A fire line is constructed parallel to, and just far enough from the fire edge, to allow firefighters and equipment to work effectively away from heat and smoke. There are many factors that determine the distance from the edge including terrain; number of firefighters available; fire’s rate of spread; the fire’s intensity.
Indirect attack involves falling back some distance from the fire perimeter – this could be up to a few kilometres at times – and burning back from a strong control line such as natural barriers, roads, tracks, firebreaks, or from trails or fire lines constructed.
Where a fire is too intense for direct or parallel attack eg when flame height is greater than 3 metres, spotting is occurring, or the terrain is inaccessible to firefighters, the indirect method of control may be used. If the fire’s behaviour is too severe, an indirect attack may only be possible on the flanks of the fire.

(2) Defensive Strategy -
The first-priority in defensive operations is safety and all crews must always be accounted for. Focus of effort is concentrated on property protection or structural triage.
Line defence is used when conditions would normally allow an offensive attack (eg the fire is not intense, weather conditions are favourable), but there are not enough resources to mount an offensive attack in time. It involves preventing the approaching line of fire from closely approaching the property.
Ember is used when the approaching line of fire is too intense to be suppressed by offensive means and is producing significant ember attack. It involves extinguishing small fires that occur in and around buildings.
Firefighters operate from safe positions behind suitable shielding from the main fire or pull back to a safer refuge, until the main fire front has passed.
Backstop is used when there is no safe defensible space around buildings; the approaching fire is so intense that firefighters cannot safely protect the buildings.
Firefighters withdraw temporarily a short distance away to suitable safe refuges, with the intention of coming back after the fire passes.

(3) Safeguarding strategy -
When offensive or defensive strategies are no longer viable with intense fires under the worst conditions, the actions during safeguarding strategy, while not fire suppression, warns, escorts (moves) and protects community members to ensure their safety.

Question 114

To minimise the risk of heat related illness, what is the minimum level of PPE that should be worn at a bushfire.

A defensive strategy aims at life and property protection and containment of large, rapidly moving fires, operating away from the hazards.

Question 118

What does the Incident Action (IAP) usually describe?

Answer 118

The IAP describes, at any point in time, the risk assessment, strategy and objectives, incident structure, layout of the incident, and any other relevant information.

Question 119

At a high-rise structure fire, what are the actions of the first arriving Station Commander?

Answer 119

Because the first-arriving crew needs to commence operations on the fire floor as soon as possible, the Station Commander will accompany them. The first Station Commander becomes the Sector Commander for the fire floor, establishes a Forward Control Point and commences fire operations from the floor below the fire. The actions of the first arriving station commander are:
• identify the fire location from the Fire Indicator Panel (FIP), Sub Indicator Panel (SIP) or occupants
• brief the Pump Operator according to the situation. Actions may include:
− monitor communications
− establish BA Control
− leave lift/fire control room/pump room keys for next arriving stations
− send a sitrep message to the ComCen as instructed by the Station Commander
and provide a sitrep to next arriving officer.
• go to the reported fire floor with the crew using the emergency lift to the floor below the fire floor—if safe to use—or the fire stairs
• familiarise the crew with floor layout
• charge a line of 38mm hose from the fire stairs or the floor below before entering the fire floor
• use the fire stairs to the fire floor
• conduct fire operations on the fire floor.

Question 155

During a bushfire, a helicopter is carrying out hot refuelling operations to prepare for ongoing water bombing operations. A designated Fire Protection Crew should follow what procedures?

Answer 155

When working with water bombing aircraft fire crews should:
• Be alert, watch and listen for the noise of low flying aircraft. If near a water bombing target, move to a safe distance clear of the target area.
• Evacuate the area, when seeing an aircraft make a dummy run, and take cover. Dummy runs are often conducted by the pilot to correctly identify the target.
Helicopter pilots will often use a siren to warn that they are about to water bomb.
Forward Commanders are to ensure that ground crews are cleared from target areas before water is released.
Fire protection operations for helicopter hot refulling:
Locate the appliance uphill, upwind and at least 50 metres from:
• the helicopter landing site
• fuel pumps and fuel storage areas
• any incident on the airbase.
During refuelling, firefighters in full PPE will stand by with lines of hose charged, foam eductor attached and B Class foam ready to be inducted.
Prevent water or foam streams from hitting moving rotors as this may cause catastrophic failure of the rotors and cause serious injury or death for people nearby.
When life is not at risk, advice should be sought on how to minimise damage to the aircraft before applying foam or water streams.
When life is at risk, the NSWFB Commander should direct firefighters to apply foam to a fuel fire immediately.

Answer 159

A hazard is anything in the workplace that has the potential to cause harm to a person. Hazards can be an object or thing; for example, an acetylene cylinder; a hazardous manual task; or the way work is done.

Hazards are often grouped into categories by their type, for instance:
• Physical hazards ‐ such as plant & equipment
• Chemical hazards ‐ such as hazardous substances
• Ergonomic hazards ‐ such as hazardous manual tasks
• Psychosocial hazards ‐ such as critical incidents

A risk is the harm that may occur to a person exposed to a hazard.
The level of risk is dependant on the severity of harm (consequence) that may be caused and the likelihood of that harm occurring.
Consequences:
Insignificant, Minor, Moderate, Major and Extreme
Likelihood:
Almost Certain, Likely, Possible, Unlikely and Rare
Risk evaluation results/scores:
Very Low (1-3), Low (4-7), Moderate (8-15), High (16-20), Very High (21-25)

Question 169

You are responded to an aircraft on a runway with smoke issuing from behind the piston engine. All passengers and crew are out. It is a radial engine. How does the fire risk of this engine compare to an in- line engine and what extinguishing medium would you use?

Answer 169

In a radial engine, the piston assemblies are arranged around the crankshaft like the spokes of a wheel. Large engines are usually of the radial type. This type of engine presents the greater fire risk. The greater fire risk in this type of engine is in the ancillary equipment. This equipment is usually housed in a bay behind the cylinders. The fire risk in this area is in the oil pumps, generators, carburetors, and superchargers and in the pipework and wiring. Halons or CO2 are most effective in controlling these fires. Foam should be avoided as piston engines must be completely dismantled if foam is used.
In an in-line engine, the piston assemblies are arranged one behind the other as in motor vehicles.

Question 194

Insulated Sandwich Panels (ISPs), especially those with Expanded Polystyrene (EPS) cores can create an extremely hazardous environment for firefighters and may force adoption of a defensive strategy from an early stage. What are the reasons for this?

Answer 194

(1) EPS melts and flows like a liquid. It is highly flammable, inducing rapid fire spread, which is undetectable with thermal imaging cameras (due to the insulating properties of the panels) and can spread to areas remote from the fire origin.
a. Panel delamination, where the hot metal panel skins bow and open up, rapidly increases the rate of fire spread, which heats the ceiling void, creates secondary pool fires from melted EPS, and causes panels to collapse (Figure 2).
b. There is an increased risk of flashover and backdraught.
c. Large volumes of toxic, thick, black, acrid smoke are produced.
(2) Sudden, loss of structural integrity may cause substantial building collapse.

Question 195

Question 203

During the de-escalation of an incident, at what stage is command terminated?

Answer 203

Command is only terminated when the last resource leaves the incident.

Question 204

What are principles of situational evaluation in incident management?

Answer 204

Collect and evaluate relevant information about the incident, to determine incident critical factors.
• The Incident Commander (IC) must identify a set of critical factors – ie elements that, if not dealt with rapidly, could cause expansion of the incident or a threat to firefighters or others – and process them into an incident action plan (IAP).
• The IC can only deal with 3-7 critical factors at any one time. If there are more than this, consider expanding the incident structure so that delegation can occur.
• Collecting and evaluating information may start before arriving on scene.
• Once on scene, further information is collected and rapidly evaluated via an initial size up from the vehicle. Whenever possible, the IC should collect additional information via a 360 degree size up.
• Critical factors must be communicated to FireCOM.
• The IC should continually collect information during the incident from commanders and other external sources such as onsite experts, Bureau of Meteorology, and other agencies.
• Critical factors may change rapidly as the incident evolves. The IAP must be modified as critical factors change.
• The IC’s initial size up and decision-making about critical factors may need to be rapid. Once the incident is contained, the IC should take a more deliberate approach.
• Situation evaluation only ends when command is terminated.
• Anyone at the incident may collect information regarding critical factors. These need to be communicated to the IC. Critical safety concerns can be addressed immediately if required, before informing the IC.

Question 205

State why the thermal imaging camera may or may not be suitable for use in a flammable atmosphere.

Answer 205

Thermal imaging cameras are not intrinsically safe. Do not use these cameras in potentially flammable atmospheres.

Question 206

A major goal for the IC is to develop an Incident Action Plan for the incident. What is an incident action plan?

Answer 206

An Incident Action Plan (IAP) is the plan developed by the IC that describes, at any one point, how the IC plans to resolve or control the incident, the risk assessment, strategy and objectives, incident structure, layout of the incident, and any other relevant information.

Question 207

What are the terms used in an initial radio report, to indicate the size of a structure at a fire incident.

Question 217

Door entry - What are the door entry techniques that can be used with the Halligan tool?

Answer 217

Inward Adze Roll Technique or alternatively the Outward Adze or Fork Drive techniques

Question 218

Door entry - What are the five steps to forcing a door?

Answer 218

(1) Size up – Assess how urgent the situation is. If it is not time critical, consider passive ways of making entry- Through a window, wait for keys etc. Conduct 360 of premises, trying all windows and doors.
(2) Gap – Usually starting with the Adze blade, work the tool between the door and door stop or door frame to create a workable gap. A second fire fighter may be required with sledge axe to “strike” Halligan tool to get a start.
(3) Set – With a gap established between the door and frame (a wedge may be required), manoeuvre tool to complete the forced entry. This could be the Adze or fork end of the tool, depending on situation.
(4) Force – Final action to defeat the lock. Using the mechanical advantage leverage of the tool to complete the spread. Two fire fighters may be required for some doors.
(5) Control – Open the door in such a way so as not to have an adverse effect on the situation. Use Adze on Halligan to hook the back of the door to pull closed.

Question 219

During Firefighting Operations, what does fire attack crew never ignore?

Answer 219

FIRE ATTACK crew never ignores a casualty

Question 220

Search and rescue during firefighting operations-The objective of a search is to confirm an ALL CLEAR, this is usually broken into what two components?

Answer 220

The PRIMARY SEARCH is rapid and systematic, usually carried out simultaneously with fire attack, if fire conditions and crew response allow.
A SECONDARY SEARCH is more thorough and methodical, undertaken to confirm casualties have not been missed. The secondary search is often conducted once Fire control has been achieved and at times can be done simultaneously with ventilation.

Question 221

Describe the terms withdraw and abandon as used by the IC to indicate to crews the urgency required to move from offensive to a defensive strategy.

Answer 221

• Withdraw – this indicates that firefighters have enough time to exit the structure or the position they are working in, with all their equipment, in a controlled manner. It is usually given by the IC in response to a tactical CAN report. An example of a message given to a Sector Commander or crew could be: Sector Commander Bravo we are changing strategy to defensive for the entire structure withdraw all crews and report PARS on exit. If there is more than one sector then this would be conveyed to all sectors.

• Abandon – this indicates that there is an immediate threat to firefighter lives and the firefighters must exit the structure or position they are working in immediately and only bring equipment with them if it will not compromise their safety. This could be that a fire has rapidly escalated, wall collapse is imminent, or a trench is about to collapse. An example of a message is: All sectors roof collapse imminent we are going to a defensive strategy abandon your positions and report if you do not have a PAR. The term abandon should be the exception rather than the rule

Question 222

What signs would indicate it’s time to withdraw during Search and rescue during firefighting operations?

Answer 222

• Worsening fire/smoke conditions
• Signs of structural collapse (see STP 33Z)
• Previously unknown hazards e.g. Acetylene
• Emergency Radio Message signaling:
- Loss of PAR
- Change to a Defensive Strategy via an order from the I.C. to Withdraw or Abandon.

Question 223

If the TIC needs to be handed between members of firefighting or search and rescue teams what is the safest method to pass to the front firefighter?

Answer 223

If the TIC needs to be handed between members of firefighting or search and rescue teams then it is safest to do so around the side of the body of the front firefighter and not over the shoulder.

Question 224

What is the purpose of placing an appliance in the fend off position?

Answer 224

Question 230

Occasionally, FRNSW personnel may have to prepare a helicopter landing site. List the points to be considered when doing this.

Answer 230

• position the landing site in an area 30 m x 30 m minimum, on solid, level ground away from power lines or wires, and clear of trees or similar obstacles
• mark the corners of the landing site by placing a firefighter at each corner and cordon off to prevent unauthorised entry. Do not use tape or loose materials
• clear all loose debris from the area, e.g. paper bags, cigarette cartons, aluminium cans etc, and secure all NSWFB equipment near the landing site
• in dry, dusty conditions, the landing site may require wetting down to maintain visibility during landing and take off.

During night landings, place a strobe light and two vehicles with beacons flashing facing into the wind and facing inwards at 45° to the approach line with their headlights on. Ensure that the strobe light is turned off once the helicopter has identified or flown over the landing site.

CAUTION Do not face lights into the aircraft approach path. The light may diffuse on the windscreen and blind the pilot.

Question 231

Where FRNSW is requested to assist the NSW RFS at a structure fire in a rural Fire District who will be the Incident Controller?

Answer 231

Where the NSWFB is requested to assist the NSW RFS at a structure fire in a rural Fire District, the senior officer from the NSW RFS present at the fire will be the Incident Controller.

Question 232

List four safety precautions when using extension ladders.

Answer 232

Using ladders
The maximum number of persons permitted on the ladder at any time is two.
Exercise care when ascending and descending ladders.
Firefighters climbing the ladder must ensure they have 3 points of contact on the ladder. A point of contact is either a hand holding a rung, or a foot firmly placed on a rung.
An firefighter must always foot the ladder by standing on the anti-slip feet and holding either the rungs or the handles when anybody is on the ladder.
Maintain a working angle of 4:1. For every 4 metres the head of the ladder extends up the wall, the base of the ladder must be a metre from the wall. If the head extends 8 metres up the wall, the base must be 2 metres from the wall, etc.
Electrical hazards
Take extreme care when working near electrical hazards such as overhead power lines. Keep all people and objects in contact with people, a safe distance from the live electrical apparatus. Maintain a minimum safe work distance of 8 metres if you are unsure of voltage. Maintain constant vigilance.
Increase the safe working distance to 25 metres if there is fire under or near a high voltage power line, due to the risk of arcing.
Personal Protective Equipment
Firefighters must wear personal protective clothing and equipment as determined by the Incident Commander according to the nature of the incident. At a minimum, wear Level 3 PPE with eye protection while handling ladders.

Question 233

When must Level 1 or Level 2 Rehabilitation be considered?

Answer 233

Level 1 Rehab – recommended for small incidents not requiring the response of a specialist incident ground rehabilitation capability. Level 1 Rehab uses equipment carried on front line firefighting appliances. Generally, the Incident Controller (IC) manages Level 1 Rehab.

Level 2 Rehab – recommended for:
• long duration incidents
• in circumstances where crew rotation is limited
• hot and dry, or cold and wet, conditions
• where working conditions are arduous
• where breathing apparatus usage and rotation is high, or
• where conditions are such that specialist incident ground rehabilitation capabilities are required. Generally, the IC appoints a dedicated Rehabilitation Officer for these incidents.

Question 234

What two items do FRNSW use that lays out safe working practices to manage the safety of firefighters at incidents?

Answer 234

FRNSW manages the safety of firefighters at incidents by providing training and doctrine that lays out safe working practices.

Question 235

According to SOGs - There are many aspects to ensuring safety at an incident, from the IC implementing the correct strategy, down to the firefighters wearing the right PPE for their assigned tasks. Incident safety can therefore be described in terms of what three levels?

Answer 235

Individual – task level
Work safely to implement tactics

Commanders – tactical level
Organise and deploy resources safely to meet the IAP objectives

Incident Commander – strategic level
Implement and maintain systems of work for safety and monitor the impact of hazards outside of the incident

Question 236

Describe the term Short Term Exposure Limit (STEL).
