You must:
Prohibit positioning the elevating work platform against another object in order to steady the platform.
Do the following when other moving equipment or vehicles are present:
Take special precautions to meet the requirements of local ordinances or workplace safety standards;
AND
Use warnings such as, but not limited to, flags, roped-off areas, flashing lights and barricades
[]
Condition of the ground or support surface;
Congestion;
Visibility;
Slope;
Location of personnel;
Other factors that may create a hazard of collision or injury to personnel.
[]
IMPORTANT:
This section does not apply to manually propelled elevating work platforms.
You must:
Make sure the operator does all of the following before and while driving with the platform elevated:
Maintains a clear view of the path of travel
Keeps a safe distance from obstacles, debris, drop-offs, holes, depressions, ramps, and other hazards to safe travel
Keeps a safe distance from overhead obstacles
Prohibit stunt driving and horseplay.
[]
You must:
Have the operator make sure all of the following are done before each elevation of the platform:
The elevating work platform is on a surface that is within the limits specified by the manufacturer
Outriggers, stabilizers, extendable axes, or other stability enhancing means are used as required by the manufacturer
Guardrails are installed and access gates or openings are closed per the manufacturer's instructions
The load and its distribution on the platform and any platform extension does not exceed the manufacturer's rated capacity for the configuration being used
There is adequate clearance from overhead obstructions
The minimum safe approach distance (MSAD) to energized power lines and parts listed in Table 6, Minimum Safe Approach Distance, is maintained
All persons on the platform are wearing fall protection devices and other safety gear if required
Prevent rope, electric cords, hoses and similar objects from becoming entangled with the platform.
Have the operator make sure the area is clear of personnel and equipment before lowering the platform.
Remove all personnel from a platform that has been
caught, snagged, or otherwise prevented from normal motion
before attempting to free it using ground controls.
Note: | If possible, reverse the platform controls to free a platform that is caught, snagged, or otherwise prevented from normal motion by an adjacent structure or other obstacle. |
Table 6
Minimum Safe Approach Distance
Voltage | Minimum Safe Approach Distance |
Less than 300 volts (insulated lines) | 3 feet (0.9 m) |
Less than 300 volts (uninsulated lines) | 10 feet (3.1 m) |
300 volts to 50 kv | 10 feet (3.1 m) |
More than 50 kv | 10 feet (3.1 m) + 0.4 inches (1.0 cm) for each 1 kv over 50 kv |

You must:
Make sure persons working from the platform:
Keep a firm footing on the platform;
AND
Do not use guardrails, planks, ladders, or any other device to gain additional height or reach
Make sure all persons on the platform of boom-supported elevating work platforms wear a full body harness and lanyard fixed to manufacturer provided and approved attachment points.
Make sure the rated capacities of the platform are not exceeded when transferring loads to the platform at any height.
Note: | Guardrails are the primary means of fall protection for manually propelled elevating work platforms. |
[]
You must:
Make sure operators, if they suspect a malfunction of the elevating work platform or encounter any hazard or potentially unsafe condition, do all of the following:
Cease operation
Report the problem or malfunction
Discontinue using the elevating work platform until problems or malfunctions that affect safe operation have been corrected
