Intended use
You must
- Make sure elevating work platforms are used only for their intended purpose as specified by the manufacturer.
|
|
Note:
|
Workplace survey
You must
- Have the operator survey the area before and during use of an elevating work platform for hazards such as:
- -Drop-offs or holes
- -Slopes
- -Bumps and floor obstructions
- -Debris

- -Inadequate surface and support to withstand the load imposed on them by the elevating work platform in all operating configurations
- -Wind and weather conditions
- -Unauthorized persons in the area
- -Other possible unsafe conditions
Hazardous locations
You must
- Determine the hazard classification of any area where the elevating work platform will operate using National Fire Protection Association (NFPA) 505-2002, Fire Safety Standard for Powered Industrial Trucks Including Type Designations, Areas of Use, Conversions, Maintenance, and Operations.
- Make sure only approved elevating work platforms are used in Class I, II, or III locations.
- Make sure elevating work platforms are used in hazardous (classified) locations as follows:
- -Elevating work platforms authorized to be used in Class 1 locations are shown in Table 3, Approved Elevating Work Platform Use in Class 1 Locations
- -Elevating work platforms authorized to be used in Class 2 locations are shown in Table 4, Approved Elevating Work Platform Use in Class 2 Locations
- -Elevating work platforms authorized to be used in Class 3 locations are shown in Table 5, Approved Elevating Work Platform Use in Class 3 Locations
- Elevating work platforms authorized to be used in unclassified locations are:
- -Approved elevating work platforms designated as Type D, E, G, or LP;
and - -Elevating work platforms that meet the requirements of Type D, E, G, or LP elevating work platforms.
- -Approved elevating work platforms designated as Type D, E, G, or LP;
- Have operators report any hazardous atmosphere or location that becomes apparent while operating the elevating work platform.
|
|
Definition: An unclassified location is an area that's not designated as a Class 1, 2, or 3 location. The type designation is a code to identify types of elevating work platforms. It is used to determine if an elevating work platform can be used in a specific classified or unclassified location.

Set-up
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
- -Take special precautions to meet the requirements of local ordinances or workplace safety standards;
Travel speed
You must
- Make sure the operator limits travel speed according to conditions, including:
- -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 doesn't 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
Elevating and lowering the platform
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 doesn't 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. |

Working from the platform
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
- -Keep a firm footing on the platform;
- 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 aren't 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. |
Malfunctions or unsafe conditions
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
