1. Definitions - For purposes of this Rule, the following definitions shall apply:
ACCIDENTAL CONTACT - Any inadvertent physical contact with power transmission equipment, prime movers, machines or machine parts which could result from slipping, falling, sliding, tripping or any other unplanned action or movement.
AIR CONDITIONING - The process of treating air so as to control simultaneously its temperature, humidity, cleanliness and distribution to meet the requirements of the conditioned space.
BALLUSTRADES - The frames on either side of the moving steps of an escalator.
BOILER - A closed vessel for heating water or for application of heat to generate steam or other vapor to be used externally or to itself.
BUFFER - A device designed to stop a descending car or counterweight beyond its normal limit of travel by absorbing and dissipating the kinetic energy of the car or counterweight.
CAGE/CAB - An enclosure for housing the operator and the hoisting mechanism, power plant and equipment controlling a crane.
CAPACITY OF WORKS, PROJECT OR PLANT - The total horsepower of all engines, motors, turbines or other prime movers installed, whether in operation or not.
CAR - The load-carrying unit of an elevator including its platform, frame, enclosure and door or gate.
COMPRESSOR - A mechanical device for the purpose of increasing the pressure upon the refrigerant.
CONDENSER - A vessel or arrangement of pipes or tubing in which vaporized refrigerant is liquified by the removal of heat.
CONDEMNED BOILER OR UNFIRED PRESSURE VESSEL - A boiler or unfired pressure vessel that has been inspected by the Building Official and declared unsafe or disqualified and power stamped or marked designating its rejection.
CRANE - Means a machine for lifting or lowering a load and moving it horizontally, the hoisting mechanism being an integral part of the machine.
DUCT - A passageway made of sheet metal or other suitable material not necessarily leak tight, for conveying air or other gases at low pressure.
DUMBWAITER - A hoisting and lowering mechanism equipped with a car not to exceed 3861 sq. cm. in area and a maximum height of 1.20 m., the capacity of which does not exceed 277 kilos, used exclusively for carrying materials.
ELEVATOR - A hoisting and lowering mechanism equipped with a car or platform which moves in guides in a vertical direction serving two or more floors of a building or structure. Movement of the car may be controlled by gravitational, manual or mechanical power.
ELEVATOR LANDING - That portion of a floor, balcony or platform for loading or discharging passengers or freight to or from the elevator.
ELEVATOR WIRE ROPES - Steel wire ropes attached to the car frame or passing around sheaves attached to the car frame from which elevator/dumbwaiter cars and their counterweights are suspended.
ENCLOSED - Means that the moving parts of a machine are so guarded that physical contact by any part of the human body is precluded or prevented. This does not however prohibit the use of hinged, sliding or otherwise removable doors or sections to permit inspection, lubrication or proper maintenance.
ESCALATOR - A power driven, inclined, continuous stairway for raising or lowering passengers.
EVAPORATION - That part of the AC/Refrigeration system in which liquid refrigerant is vaporized to produce refrigeration.
EXTERNAL INSPECTION - An inspection made on a boiler during operation.
GUARDED - Shielded, fenced or otherwise protected by means of suitable enclosure guards, covers or standard railings, so as to preclude the possibility of accidental contact or dangerous approach to persons or objects.
HOIST - An apparatus for raising or lowering a load by the application of a building force, but does not include a car or platform. It may be based-mounted, hook suspension, monorail, over- head, simple drum type or trolley suspension.
HOISTWAY - A shaftway for the travel of one or more elevators or dumbwaiters.
INTERNAL INSPECTION - An inspection made when a boiler is shut down, with hand-holes, manholes, or other openings opened or removed to permit inspection of the interior.
LIQUID RECEIVER - A vessel permanently connected to a system by inlet and outlet pipes for storage of a liquid refrigerant.
LOCOMOTIVE BOILER - A boiler mounted on a self-propelled track locomotive used to furnish motivating power for traveling on rails.
LOW PRESSURE HEATING BOILER - A boiler operated at pressures not exceeding 1.05 kg/sq.m. with steam or water temperature not exceeding 250°F.
MACHINE - The driven unit of an equipment.
MACHINE HOUSE - An enclosure for housing the hoisting mechanism and power plant. MACHINE PARTS - Any or all moving parts of a machine.
MECHANICAL EQUIPMENT, MACHINERY OR PROCESS - Includes steam engines, internal combustible engines, boilers, turbines, crushers, mills, mixers, pumps, compressors, cranes, conveyors, hoists, elevators, escalators, dumb waiters, pipe lines, line-shaftings, air conditioning, refrigeration, ventilation, pressure vessels and the like.
MECHANICAL WORKS, PLANT - Includes steam plants, internal combustion engine plants, hydraulic power plants, pumping plants, refrigerating plants, air conditioning plants, mill shops, factories, foundries shipyards, etc. containing any mechanical equipment, machinery or process, driven by steam, internal or external combustion fuel, electricity, gas, air, water, heat, chemicals or other prime movers.
MOVING WALK - A type of horizontal passenger-carrying device on which passengers stand or walk, with its surface remaining parallel to its direction of motion and is uninterrupted.
POINT OF OPERATION - That part of a machine which performs an operation on the stock or material and/or that place or location where stock or material is fed to the machine. A machine may have more than one point of operation.
PORTABLE BOILER - An internally fired boiler which is self-contained, primarily intended for temporary location.
POWER TRANSMISSION MACHINERY - A shaft, wheel, drum, pulley, system of fast and loose pulleys, coupling, clutch, driving belt, V-belt sheaves and belts, chains and sprockets, gearing, torque connectors, conveyors, hydraulic couplings, magnetic couplings, speed reducers
