(a) toothed wheels of builders' power hoisting winches;
(b) friction wheels of builders' power hoisting winches;
(c) toothed wheels of the longitudinal travelling mechanism of power-driven overhead travelling cranes if exposed above or partially above access platforms, access facilities or end carriages;
(d) toothed wheels of locomotive type power cranes and power cranes having an analogous arrangement of machinery if the wheels revolve in close proximity to crane frame structures;
(e) toothed wheels of, and adjacent to, the mixing vessels of power-driven concrete mixers and like mixers, including positions at which the wheels revolve in close proximity to the frame structures of the mixers;
(f) those members, components, parts or attachments that are within reach of access facilities, floors, the ground, or other working surfaces and that revolve and are of irregular, radially variable, intermittent, broken or gapped contour or have projecting keys, setscrews, bolt ends, nuts, pins (including split pins), bosses, dogs, lugs, ribs, fins, arms or the like because of which they may directly or indirectly engage the person or clothing.
(g) ends of revolving shafts, spindles, pins or axles that are within reach and that project more than 2 inches beyond their supports;
(h) transmission belting and transmission chains that are within reach;
(i) power-driven revolving shafts, spindles, pins or axles if exposed at or near accessholes, hatchways, doorways, gateways or like facilities, or if exposed in such positions with regard to access facilities that persons are likely to make contact with them;
(j) power-driven shafts, spindles, pins, axles, drums, couplings, toothed wheels, rollers or the like revolving above the upper surfaces of floors, platforms, walkways, pathways and the like wherever an unobstructed minimum clearance of 2 1 / 2 inches does not at all times exist between the revolving member and the surface;
(k) power-driven spoked wheels and wheels having web apertures if the wheels revolve in close proximity to the frame structures of cranes, engines or gear;
(l) power-driven fans or blowers, including cooling fans of internal-combustion engines;
(m) hoods or cowlings that may be readily removed or displaced shall not be deemed to be effective guards;
(n) all members, components, parts of attachments liable to attain a temperature in excess of 140° Fahrenheit or that are liable to discharge flame, gas, vapour or liquid exceeding that temperature.
(2) In subsection (1) (f), ordinary, plain, concentric spur or worm gearing shall not be deemed to be of irregular, radially variable, intermittent, broken or gapped contour.
(3) The guards shall be constantly maintained in position in a state of complete effectiveness.
(4) If so situated that a person may climb or rest on it each guard shall be capable of sustaining, without permanent distortion, a weight of 170 pounds placed in any position on it, together with a simultaneous force of 50 pounds applied horizontally in the same or any other position.
(5) Protruding or projecting levers, handles, rods, links, bolts, spikes, pins, or other members of less than 2 square inches sectional area shall be so guarded or fenced that they will not endanger the eyes of persons in the vicinity.
