If these standards are adopted for governmental use, the references to other national codes and standards in the specific volumes may be changed to refer to the corresponding regulations of the governmental authorities. The use of cableways, cranes, derricks, hoists, hooks, jacks, and slings is subject to certain hazards that can- not be met by mechanical means but only by the exercise of intelligence, care, and common sense.
It is there- fore essential to have personnel involved in the use and operation of equipment who are competent, careful, physically and mentally qualified, and trained in the safe operation of the equipment and handling of the loads. Serious hazards are overloading, dropping or slipping of the load caused by improper hitching or slinging, obstructing the free passage of the load, and using equipment for a purpose for which it was not in- tended or designed.
The Standards Committee fully realizes the impor- tance of proper design factors, minimum or maximum sizes, and other limiting dimensions of wire rope or chain and their fastenings, sheaves, sprockets, drums, and similar equipment covered by the Standard, all of which are closely connected with safety. Sizes, strengths, and similar criteria are dependent on many different factors, often varying with the installation and uses. These factors depend on the condition of the equipment or material; the loads; the acceleration or speed of the ropes, chains, sheaves, sprockets, or drums; the type of attachments; the number, size, and arrange- ment of sheaves or other parts; environmental condi- tions causing corrosion or wear; and many variables that must be considered in each individual case. The rules given in the Standard must be interpreted ac- cordingly, and judgment must be used in determining their application.
The Standards Committee will be glad to receive crit-icisms of this Standard’s requirements and suggestionsfor its improvement, especiaily those based on actual ex-perience in application of the rules.
suggestions for changes to the Standard should be
submitted to the Secretary of the B30 Committee,ASME,Three Park Avenue, New York,NY 10016-5990,
and should be in accordance with the following for-mat:
(a)Cite the specific paragraph designation of the per-tinent volume.
(b) Indicate the suggested change (addition, deletion,revision, etc.).
(c) Briefly state the reason and/ or evidence for theSuggested change.
d)Submit suggested changes to more than one para-graph in the order that the paragraphs appear in the vol-ume.
The B30 Committee will consider each suggestedchange in a timely manner in accordance with its pro-cedures.
