Never ride on vehicle when it is in motion. Fall from moving vehicle may injure or kill. FAMA24 Do not paint over this label. Replace if damaged or lost FAMA24 This vehicle is not designed for personnel to ride anywhere other than inside the vehicle in a seated and belted position. Exterior handles are provided to assist in entry and exit only, they are not to be used for hanging on to a moving vehicle. 1-8. Know Your Aerial Device 1-8.1 Emergency Stop Your aerial device will have method of stopping all aerial functions. On Command Zone equipped aerials this will be an emergency stop (E-Stop) at each control station. For direct hydraulic valve devices, all aerial functions will be stopped by removing your foot from the operator presence switch. If something goes wrong or the aerial is behaving in a manner you do not understand, stop all aerial functions. Clear personnel from the area and determine what is wrong before resetting the E-Stop or depressing the operator presence pedal and continuing operation. Be sure that all controls are in the neutral position before resuming operation. Practice stopping all aerial functions on your supervisor's command until it becomes second nature so that your mind will react quickly in an emergency. © 2017 Pierce Manufacturing Inc. All Rights Reserved. Rear Mount Aluminum Platform - Command Zone™ Controls / 1-9 SAFETY 1-8.2 Emergency Power Unit Your aerial device is a complicated machine with many moving parts. The power for movement is supplied by a hydraulic pump that is driven by a power-take-off from the engine. It is always possible that a mechanical, electrical or hydraulic failure can occur that will interfere with the operation of your aerial device. The Emergency Power Unit (EPU) will provide back-up power and, in most cases, allow you to continue operation until you can recall personnel from harm's way, stow the device and remove it from the emergency scene for repair. Study the operation of the EPU so you are prepared if you need to use it during an emergency. Do not rely on the EPU for extended use as it is not designed for continuous operation. 1-8.3 Manual Valve Controls Figure 1-6: M0343 Warning Label WARNING Tipping Hazard. Using manual controls overrides safety systems Do not use unless you are trained and authorized Follow load chart Use spotters for guidance during motion Use manual controls to retract and stow device if normal control system fails Stow device in cradle before using stabilizer manual controls Remove device from service until repaired Failure to comply may injure or kill. M0343 Do not paint over this label. Replace if damaged or lost M0343 Your apparatus allows you to control the motion of the aerial device and the stabilizers by manually operating the control valves. During this operation, all safety systems are overridden. Manual valve operation must be done with extreme care and only by a trained operator who understands the load charts thoroughly and has calculated the safe operating conditions at the scene. Manual valve control will allow the device to move into areas where the device may become unstable and tip over. Other disabled interlocks may allow the device to make contact with the body or cab. Only use manual valve controls in an emergency or in completely controlled conditions. You must learn where these manual valve controls are located and how to operate them. Practice using them under supervision and in controlled conditions until you are just as proficient with them as you are with the normal controls. If the normal control system malfunctions, remove personnel from harm's way immediately and take the device out of service until it can be repaired. Use emergency manual valve controls with extreme caution and only when all non-essential personnel are well clear of any hazard. 1-10 / Rear Mount Aluminum Platform - Command Zone™ Controls © 2017 Pierce Manufacturing Inc. All Rights Reserved.  SAFETY 1-8.4 Aerial Interlocks Interlock Failure Hazard Understand your device and how it is intended to function Never rely on interlocks to ensure safe functioning Check interlock functions frequently This aerial device is equipped with a number of interlock functions, many of which are required by NFPA 1901. Interlock devices are intended to reduce the possibility of unsafe actions, but they should never take the place of careful, thoughtful, and prudent operation. Department procedures should identify each interlock and provide a procedure on how to safely ensure that each is functioning. Aerial device interlocks may include: Aerial/Stabilizer The aerial device function must not activate unless the stabilizers are fully deployed. Body Collision The device will not move into regions where it would make contact with the apparatus body or cab. Rotation Interlock (Short-Jack) The aerial device will not rotate over the side of the apparatus where the stabilizers are not fully extended. Maximum Elevation Slow-Down The device will slow down prior to reaching maximum elevation or extension. Nozzle Stow Device will not drop into the cradle if the master stream nozzle is not properly positioned. Aerial Function Interlocks The aerial device will not operate until the parking brakes have been set and the transmission has been placed in neutral or the transmission is in the drive position with the driveline to the rear axle disengaged. 1-9. Safe Aerial Set-Up 1-9.1 Aerial Apparatus Positioning Selecting the right location to set up your aerial apparatus when arriving on scene is one of the most important decisions you will make. You must anticipate what you will be doing with your apparatus and identify areas where it can be positioned so that the aerial can reach the final position without exceeding its reach and capacity. Your aerial apparatus is very heavy, and it must have ground under it that will support its weight during all operations. Your selected position must meet all of the following safe positioning criteria: Surface must be firm and stable. Stability cannot be assured on grass, dirt, hot asphalt, etc… Avoid loose objects, underground utility access covers, chambers, pipes, culverts, broken pavement and areas that drop off suddenly. Apparatus must be able to be leveled within the safe operating limits. Set-up area should ensure clearance from power lines during operation. © 2017 Pierce Manufacturing Inc. All Rights Reserved.
