22.M.04 Transporting.
Aerial lifts are used frequently in shipyard repair.
- Aerial lift trucks, to include cherry pickers, must not be moved when the boom is elevated in a working position with personnel in the basket except for equipment that is specifically designed for this type of operation. When manufacturers allow mobile operation, the worksite must be inspected for:
- (1) Untamped earth fills (soft ground);
- (2) Ditches;
- (3) Drop-offs and floor obstructions;
- (4) Debris;
- (5) Overhead obstructions and electrical conductors;
- (6) Weather conditions, and
- (7) The presence of unauthorized persons.
- Before moving an aerial lift, the boom(s) must be inspected to see that it is properly cradled and outriggers are in stowed positions, except as provided above.
- Aerial ladders must be secured in the lower traveling position by the locking device on top of the truck cab and the manually operated device at the base of the ladder before the truck is moved for highway travel.
22.M.05 Operating practices.
The manufacturer's instruction for control station operation must be followed (e.g. primary versus secondary; upper versus lower).
- Brakes must be set and outriggers, when used, must be positioned on pads or a solid surface.
- Wheel chocks must be installed before using an aerial lift on an incline.
- Lift controls must be tested each day prior to use to ensure safe working condition.
- Lift controls will be located below the guardrail height. When lift controls are not located below the guardrail height, an after-market guard will be installed.
- Boom and basket load limits specified by manufacturer must not be exceeded.
- Articulating boom and extensible boom platforms, primarily designed as personnel carriers, must have both platform (upper) and lower controls.
- (1) Upper controls must be in or beside the platform within easy reach of the operator.
- (2) Lower controls must provide for overriding the upper controls.
- (3) Controls must be plainly marked as to their function.
- (4) Lower level controls must not be operated unless permission has been obtained from the employee in the lift except in case of emergency. This practice must be documented in the applicable AHA.
- Climbers (spikes) must not be worn while performing work from an aerial lift.
- The insulated portion of an aerial lift must not be altered in any manner that might reduce its insulating value.
- Occupants must always stand firmly on the floor of the basket and must not sit or climb on the edge of the basket or use planks, ladders, or other devices for a work position.
