SOG Section 28 Other emergencies Flashcards
28-01 CARBON MONOXIDE DETECTOR ACTIVATION
What are potential sources of carbon monoxide?
- car running in attached garage
- BBQ in an enclosed area
- gas or wood burning fireplace
- blocked chimney opening
- portable heater
- inproperly installed range or cook-top vent
- corroded or disconnected water heater vent pipe
- cracked heat exchanger in furnace
- leaking chimney pipe or flue
28-01 CARBON MONOXIDE DETECTOR ACTIVATION
what are the possible explinations for an occupants detector activating and departments detector not?
- the home detector is ooperating normally and has accumulated CO over a period of time, resulting in an alarm condition
- if the area has been ventilated since the time of the exposure, the altair detector may not encounter any CO
- The altair dbe faulty (possibley mis-calibrated) or the operator has improperly used the detector
- false alarm due to the cross-sensitivity of other chemicals. consider a hazardous materials response to investigate otherchemical sources
28-01 CARBON MONOXIDE DETECTOR ACTIVATION
Carbon Monoxide (CO)
A colorless, odorless toxic flamible gas formed by incomplete combustion of carbon
28-01 Carbon Monoxide Detector Activations
What are initial actions at a CO call?
- Determine if rescue or removal of occupants is required
- When entering the structure ware PPE including SCBA
- If require initiate emergency patient care
- If detector activates don SCBA
28-03 NATURAL GAS EMERGENCIES
Procedure for natural gas call
- park up-wind
- confirm natural gas leak
- ensure gas company is notified
- appropriate PPE
- isolate/evacuate/protect in place person in danger
- eliminate open sources of ignition
- consider outside shut off valve
- ensure escaping gas does not enter other buildings]
- large scale consider hazmat team, police, additional apparatus
10 use gas detector to determine concentrations - ventilate naturally or with intrinsically safe equipmetn
- do not re-open closed gas shut off valve
- personnel shall work in coordination with gas technician
- do not attempt to extinguish gas fire unless the is a threat to life
- avoid entering excavations
- avoid stopping gas leak on a plastic pipe
- do not spray water on natural gas pipe
28-04 Electrical Emergencies
Procedure for Suspected or confirmed fire in a hydro vault?
- Establish hot zone and evacuate the zone. for high rises this would include the underground garage, stairways, stairwell and the ground floor
- prevent the vault door form being opened prior to power being bonfirmed shut off by hydro representatives
- prevent entry into the vault
- have hydro respond to de-energize the vault
- protect exposures if required
- only enter the vault if necessary and after consultation with hydro, treating as a confined space entry do not make entry usnless necessary
- elevators need to be recalled to the ground floor and should not be used below grade if the building is experiencing and electrical fire either in a hydro cault or the elevator or in the buildings electrical service
28-04 Electrical Emergencies
Procedure for a rescue inside a vault with no fire conditions
- treat as a confined space entry until proven otherwise
- call for hydro to respond and de-energize the equipment
- if its a body recovery based on “ovious signs of death” wiat for hydro to respond, do not make entry
- if its a rescue, attempt to remove from outside the vault by pike pole
- if entry is required, use estreme caution, and do not make contact with electrical equipment
28-04 Electrical Emergencies
electrical substation fire procedure
- do not enter the substation area without a hydro service providor representative to excort
- civilians walking inside the fence perimeter should be directed to come to the fence and emain there
- victims or other persons on equipment shall be advised to remain stilll until a hdro service provider reprentative is on scene to provide escort to the victim
- if a hydro service provider represntative is not present when personnel arrice, they shall request one
- for high voltage transmission stations the telephone number fo the the controlling authority is usally posted on or near the ain entrance gate
- while waiting for the arrival of a hydro service provider represntatice, personnel shall
* connect their apparatus to a water supply
* stand ready to protect adjacent properties
* keeep the area clear of civilians
* if fire is psreading to o within the building on site, water may be applied form outside the fence area
* water hsll be applies in a fog appern at a minimum 700kpa nozzle pressure
28-04 Electrical Emergencies
Indicators of lithium ion battery powered devices
- low l\ying smoke conditions
- high level of CO
- lower vent velocity
- popping sounds
- unexpected fire fgrowth
- plugs or cords for eectic vehicles
- type of business
28-04 Electrical Emergencies
When lithium ion batteries are involed in a fire what should be done with them after the fire is extinguished?
- Smaller devices should be removed from the structrue and if possible put into a bucket of water
- larger devices - perosnnel should remain on fire watch for at least 24hrs, unless a responsible third party is taking over the scene
28-05 Cellulose Insulation
Cellulose Insulation
is a fiber insulation made up or primarily recycled newpring and is used prmarily fo rinsulating purposes in the wall oand attic spaces of residential homes
28-05 Cellulose Insulation
What is used to make cellulose insulation fire resistant
cellulose insulation fibres are usually treated with chemicals (ammonium sulfate and borate) to make if fire resistant, it can still result in a smoldering fire lasting for days
28-05 Cellulose Insulation
what should be done with cellulose insulation that is being removed form from a stucture fire?
A disposel area should be setup at the exterior of the stucture with a tarp for descarded insulation and firefighters should be standing by with charged hose lines. The cellulose insulation that has been removed from the building should be throughly soaked to avoid re-ignition an prevent the insulation from blowing onto neighbouring properties
28-05 Cellulose Insulation
How fare should ovehaul be with cellulose insulation involved
a perimeter (minimum of 2 meters) byond that of the involved cellulose insulation fire area should be removed to ensure that there is no fire exxtension and further fire risk.
