Upon receipt by the Secretary, the request will be forwarded to the relevant B30 Subcommittee for a draft response, which will then be subject to approval by the B30 Standard Committee prior to its formal issuance.

The equipment covered by the 1330 Standard is subject to hazards that cannot be abated by mechanical means, but only by the exercise of intelligence, care, and common sense. It is therefore essential to have personnel involved in the use and operation of equipment who are competent, careful, physically and mentally qualified, and trained in the proper operation of the equipment and the handling of loads. Serious hazards include, but are not limited to, improper or inadequate maintenance, overloading, dropping or slipping of the load, obstructing the free passage of the load, and using equipment for a purpose for which it was not intended or designed.
The B30 Standard Committee fully realizes the importance of proper design factors, minimum or maximum dimensions, and other limiting criteria 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
(a) the condition of the equipment or material
(b) the loads
(c) the acceleration or speed of the ropes, chains,sheaves, sprockets, or drums
(d) the type of attachments
(e) the number, size, and arrangement of sheaves or other parts
(f) environmental conditions causing corrosion or wear
(8) many variables that must be considered in each individual case
The requirements and recommendations provided in the volumes must be interpreted accordingly, and judgment used in determining their application.ASME B30.25 pdf download.
