Electrical contractors often use vans or trucks to transport tools and supplies. Employees may have to reach over or climb into the small, awkward areas of these automobiles.

Contractors can implement the following solutions to ease the tasks of transporting and retrieving supplies and tools from automobiles.


Truck
 

Reaching into a Vehicle
Potential Hazards:
  • Figure 1. Employee crouching in a cluttered van

    Crouching or kneeling to reach into the back of a van (Figure 1) or a truck with a shell might put contact stress on the knees and stress on the lower back.

  • Employers often use vans with a narrow, short access space to store materials. Stooping and reaching may be required to access these materials.



Possible Solutions:
  • Figure 2. Rollout truck bed deck

    Perform lifting tasks from a kneeling position and pushing and pulling tasks from a crouched position when working in cramped areas.

  • Install a roll-out truck bed deck (Figure 2). Materials will be free from the confines of the truck shell and sides, allowing employees to gain easy access to the contents of the truck. These deck platforms also provide a convenient waist-high work space.

  • Place the most commonly-used materials closest to doors or in outside truck bins, minimizing the stooping and reaching.

Loading and Unloading
Potential Hazards:
  • Figure 3. Employee lifting heavy equipment

    Lifting and lowering materials and equipment from the back of vehicles may place strain on the back.

  • Lifting toolboxes, supplies, or other materials over the sides of the truck stresses the shoulders and back.





Possible Solutions:
  • Figure 4. Hydraulic lift raising a mobile tool box

    Use a vehicle with hydraulic lift equipment (Figure 4). 

  • Use reach forklifts that extend the forks over the truck sides and lift materials out of the back.

  • Use truck ramps that allow employees to wheel loads in and out of the back of vehicles.

  • Do not lift over the sides of a truck or latched tailgate. Reposition materials closer to the tailgate so you can lift in the power zone.

  • Use a multiple-man lift when necessary. The rule of thumb is one person for every 50 pounds.
