A safety coordinator is selecting a replacement electric lift truck for a solvent-blending room. Flammable vapors are present in the room's atmosphere. The facility's current electric trucks are an ES unit (extra safeguards against sparks and high surface temperatures) and an EE unit (motors and electrical equipment completely enclosed). Which designation is intended for use in this kind of atmosphere?
Show answer and source
Answer: B. EX
The standard describes EX units as the electric trucks whose electrical fittings and equipment are designed, constructed, and assembled for use in certain atmospheres containing flammable vapors or dusts. The EE and ES units only add safeguards over the basic E unit, such as spark prevention or enclosed motors, and are not described as built for flammable-vapor atmospheres.
“The EX designated units are electrically powered units that differ from the E, ES, or EE units in that the electrical fittings and equipment are so designed, constructed and assembled that the units may be used in certain atmospheres containing flammable vapors or dusts.”
During a walk-through of a forklift charging area, a safety professional sees that an operator has parked an electric truck, set the brake, opened the battery compartment cover, and checked that the vent caps work before starting the charge. A contractor is using an angle grinder on a bracket on a workbench inside the same charging area. The grinder is throwing a steady stream of sparks. Which action does the standard require?
Show answer and source
Answer: B. Take precautions to prevent the sparks, such as stopping the grinding or moving it out of the charging area
The standard requires precautions to prevent open flames, sparks, or electric arcs in battery charging areas, so the grinding must be stopped or moved. A no-smoking rule does not cover sparks, which are a separate hazard. Closing the cover is wrong because the guidance calls for the cover to be open to dissipate heat.
“Precautions shall be taken to prevent open flames, sparks, or electric arcs in battery charging areas.”
A lift truck operator has raised a loaded pallet to the height of the top rack tier. The truck is still in the aisle, and the pallet has not yet reached the rack opening. The pallet is stable with the mast tilted slightly back. To save time, the operator wants to tilt the mast forward now so the pallet will be ready to slide off when it reaches the rack. What should the operator do?
Show answer and source
Answer: C. Keep only enough backward tilt to stabilize the load, move forward until the pallet is in a deposit position over the rack, and tilt forward only then.
The standard prohibits tilting an elevated load forward until it is in a deposit position over a rack or stack, and it limits backward tilt to what is needed to stabilize the load. Being within rated capacity or moving slowly does not lift the prohibition, and tilting fully backward exceeds the "only enough" limit.
“An elevated load shall not be tilted forward except when the load is in a deposit position over a rack or stack. When stacking or tiering, only enough backward tilt to stabilize the load shall be used.”
