6.1.8.2 Precipitation

A cover, directly over the horizontal projection of the escalator, shall be provided. The cover shall extend outward from the centerline of the handrail so that a line extended from the edge of the cover to the centerline of the handrail forms an angle of not less than 15 deg from the vertical.

When the escalator is subjected to blowing snow or freezing rain, heating systems shall be operated to prevent accumulation of snow or ice on the steps, landings, and skirt deflector devices. The heating systems' operation shall be thermostatically controlled and independent of the escalator operation.

Drains suitable for all weather conditions shall be provided to prevent the accumulation of water where groundwater and runoff can collect within the equipment.
