MAGNEGRIP VEHICLE EXHAUST REMOVAL SYSTEM
STANDARD OPERATING GUIDELINE
The following describes the purpose and recommended use
of the MagneGrip Vehicle Exhaust Removal System. The intent of the system is to remove harmful
emissions produced when apparatus engines are engaged inside the bay area
during emergency response and minor engine checks. This is accomplished by the direct capture
and removal of hazardous vehicle exhaust fumes that otherwise would be released
into the open air while the engines are operating.
To ensure the highest quality of indoor air it should be
considered the responsibility of all department personnel to use the exhaust
removal system as directed. All Personnel
should be advised of the hazards presented by exhaust emissions and take
appropriate action to reduce exposure to the harmful fumes.
Exiting the Station:
When the control panel is set in the “Auto-Mode”, upon engine startup, the
exhaust fan will automatically start and begin the capture and removal of
exhaust emissions via a pressure switch and/or transmitter. The exhaust fan
will then shut down after a pre-set time, typically 3-minutes, after the
apparatus has left the bay area.
After ensuring all personnel are
seat-belted and the vehicle is ready to move, the driver/engineer of any
vehicle attached to the system shall move the vehicle forward at a safe speed. Due to variances in spacing between
apparatus and/or bay door widths, moving at the slowest speed needed to move
the vehicle forward until completely passing the threshold of the bay door will
minimize recoiling of the exhaust tubing.
Though the release of the nozzle from
the tailpipe adapter is not reliant on the movement speed of the vehicle, it
recommended to exit at a speed of 5mph or less. This recommendation will ensure the safety of
others and will help prevent damage to the exhaust system or nearby equipment
in congested areas.
It is recommended that all personnel
remaining in the station stay clear of the exiting vehicle and detaching
exhaust system components.
Entering the Station:
Upon returning to the station, one person
(spotter) should exit the apparatus prior to entering the bay to retrieve the
nozzle of the exhaust removal system for attachment to the vehicle tailpipe
The spotter should direct the
driver/engineer to enter the bay until the tailpipe of the vehicle reaches a
designated position for attachment of the system nozzle to the tailpipe adapter.
Upon reaching this position the spotter should direct the driver/engineer to
stop to allow for nozzle attachment. To
attach the nozzle to the tailpipe adapter simply align the notches in of the
nozzle boot (@ 12, 3 & 9 o’clock) with the locating pins of the tailpipe
Once the nozzle is securely connected to
the tailpipe adapter, the exhaust fan will energize automatically and run for a
pre-set time (typically 3 minutes) and the spotter may direct the
driver/engineer to move the vehicle to its normal parking position.
Non-moving System Operation:
When a vehicle is properly connected to the
exhaust removal system, it can be started inside the bay area to allow for
brief engine and vehicle check procedures.
All engine checks should be limited to 15 minutes with engine speed no
higher than 1500rpm. All engine checks requiring higher rpm’s and extended run
time should be conducted outside with the bay doors closed to prevent
infiltration of emissions back into the bay area.
Prior to starting any apparatus engine to
perform an engine check, the control panel switch must be moved to the “Manual Mode” to start the exhaust fan
and by-pass the timer to allow for continuous operation. Once all engines are shut off the switch can
then be moved back to the auto-position to make the system ready for the next
The nozzle of the hose drop should be
inspected for obstructions that could reduce or prevent airflow.
The tailpipe adaptor should be inspected to
ensure that it is clean and in good repair for proper attachment of the nozzle. It is recommended that the tailpipe adaptor
be cleaned each time the vehicle is washed.
All tracks, rails, rollers and magnet
assemblies should be inspected periodically for proper operation and wear. All lubrication of these items should be done
using a “silicone” spray only.
For systems equipped with transmitters the
batteries should be tested and/or replaced on an annual basis.
All other maintenance or repair issues should be reported
to department personnel designated to be the exhaust system representative.
