Definition

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.

    • -D refers to elevating work platforms that are diesel engine powered that have minimum safeguards against inherent fire hazards.
    • -DS refers to diesel powered elevating work platforms that, in addition to meeting all the requirements for type D elevating work platforms, are provided with additional safeguards to the exhaust, fuel and electrical systems.
    • -DY refers to diesel powered elevating work platforms that have all the safeguards of the DS elevating work platforms and, in addition, any electrical equipment is completely enclosed. They are equipped with temperature limitation features.
    • -E refers to electrically powered elevating work platforms that have minimum acceptable safeguards against inherent fire hazards.
    • -ES refers to electrically powered elevating work platforms that, in addition to all of the requirements for the E elevating work platforms, have additional safeguards to the electrical system to prevent emission of hazardous sparks and to limit surface temperatures.
    • -EE refers to electrically powered elevating work platforms that, in addition to all of the requirements for the E and ES type elevating work platforms, have their electric motors and all other electrical equipment completely enclosed.
    • -EX refers to electrically powered elevating work platforms that differ from E, ES, or EE type elevating work platforms in that the electrical fittings and equipment are designed, constructed and assembled to be used in atmospheres containing flammable vapors or dusts.
    • -G refers to gasoline powered elevating work platforms that have minimum acceptable safeguards against inherent fire hazards.
    • -GS refers to gasoline powered elevating work platforms that are provided with additional exhaust, fuel, and electrical systems safeguards.
    • -LP refers to liquefied petroleum gas-powered elevating work platforms that, in addition to meeting all the requirements for type G elevating work platforms, have minimum acceptable safeguards against inherent fire hazards.
    • -LPS refers to liquefied petroleum gas-powered elevating work platforms that in addition to meeting the requirements for LP type elevating work platforms, have additional exhaust, fuel, and electrical systems safeguards.

  • 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

    • -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.
