CAB PROTECTION (FOR TRUCKS HAULING
GRAVEL, ROCK, DIRT, ETC.)
To test scaffold planks a simple impact loading method is as follows:
1. Select a span from the following table that is convenient for the length and size of plank to be tested. Obtain two (2) blocks about two feet (2') long and of a thickness (given in table) that corresponds to the span and plank size. Set blocks and plank on a flat surface as illustrated, so that clearance between surface and plank is uniform.
2. Have men (two should be enough) spring on the board, standing close together at mid-span, until it deflects to the surface below several times. Do not apply a load so large that the plank is held against the floor. It should touch the floor only for an instant during springing.
3. Listen for cracking and look for splitting.
4. If no cracking or splitting is noted, turn the plank over and repeat the test. If it cracks or splits, reject it.
5. In case of faint cracking sound (caused by stretching of fibers near allowable knots), repeat test, and accept plank if no further cracking sounds are heard.
Table of Block Sizes for Various Spans
Plank span, feet Plank size, * inches Block size, inches
8 2 x 10 or 2 x 12 2-1/2
10 2 x 10 or 2 x 12 3-1/2
12 2 x 12 5-1/2 *
* All planks must comply with safety orders in regard to grade, size, condition, etc.
The main advantage of this system, in addition to simplicity, is that it will show up wood that is brash or contains compression failures, while not damaging good planks.

Approval Criteria Pole Tool Assemblies
(1) The maximum extension of the pole tool assembly shall not exceed 6 feet (183 cm) in length measured from the heel of the powder-actuated tool to the trigger mechanism on the pole.
(2) The powder-actuated tool, to which the pole tool assembly is attached, shall be only of low velocity type.
(3) The extension assembly shall be of such structural integrity as to withstand the forces involved in the use of the tool.
(4) The powder-actuated tool shall be of a type whereby either fasteners or power loads must be loaded individually.
(5) The trigger mechanism shall be attached to the assembly.
(6) Pole tool extension assemblies shall either be constructed of a dielectric* material, or those portions of the trigger mechanism and pole normally held by the operator while using the tool in the upright position shall be covered with a dielectric material sufficient to preclude the possibility of electric shock or burn caused by contact between the tool or attachments with energized wiring.
* The pole tool handle and connecting controls shall be capable of withstanding for one minute, without breakdown, the application of a 60 hertz essentially sinusoidal potential of 1000 volts + 2 x (rated voltage).
EXAMPLE: 1000 + 2(600) = 2200 volts.
