4-3.3e What to Do After a Deployment
Vehicle Accident Response Information
In case it is necessary to perform the extrication of an occupant of this vehicle, performing any one of the following
will disable the roll sensor and any unfired protective devices:
•
Turn battery master switch to the OFF position, OR
• Move ignition switch to the OFF position, OR
• Disconnect the batteries, OR
• Cut the wires to the protective device actuators.
Fired protective devices pose no toxic threat to rescue personnel. After a side roll accident, the seat belts on all the
occupants will be tight, but have specially designed buckles that can be released under belt tension. Use extreme
care when releasing seat belt buckles and exiting a damaged vehicle. The bags will be filled with warm inert gases.
The gases will be nearly invisible, but will have an acrid smell. The gases pose no harm to occupants or rescue
personnel.
Pierce Customer Service must be notified whenever the Side Roll Protection System has been activated. DO NOT
remove or tamper with any Side Roll Protection System components, except to extricate the occupants.
Returning to Service
After the system is activated, the major components of the Side Roll Protection System will be deployed and cannot
be reused. The Suspension Seat Safety System (S4S), roll & slave sensor(s), Integrated Gas Pretensioners (IGP)
/ Integrated Belt Pretensioners (IBP), and Inflatable Head Curtains (IHC) / Supplemental Restraint Airbags (SRA)
must be replaced. In addition, the wiring harnesses will require inspection and possible replacement. After all system
components are inspected and/or replaced, the integrity of the system must be checked by a Pierce authorized
technician.
This service must be performed by Pierce Manufacturing or a Pierce authorized service facility.
4-3.4 Frontal Impact Protection (Optional)
The cab may be equipped with a frontal impact protection system consisting of an air bag in front of the driver, a
knee bolster air bag in front of the first officer seating position, and suspension seat safety system (S4S) for
suspension seats or belt pretensioners for fixed seats in the driver or forward first officer positions.
The driver side air bag is mounted in the steering wheel and is designed to protect the head and upper torso of the
occupant, when used in combination with the seat belt, in the event of a frontal or oblique impact.
The roll sensor is located in either the vehicle headliner or on a structural plate below the gauge cluster.
Disturbing this area, changing the position of the vehicle, or the position of the roll sensor within the
vehicle, may cause the protective devices to fire. ALWAYS deactivate the side roll protection system
when performing an extrication if unfired protective devices are present.
Protective device actuators have cylinders containing high-pressure gases and/or pyrotechnics. Hot,
pressurized gases are present in cylinders even after they have fired. These cylinders should not be
cut or punctured under any circumstances.
Do not attempt to remove any Side Roll Protection System components. Any component that did not
completely deploy requires special precautions. Contact Pierce Manufacturing for disposal
instructions for system components.
