SECTION X:ADDITIONAL GUIDANCE
The equipment covered by the B30 Standard is subjectto hazards that cannot be abated by mechanical means,but only by the exercise of intelligence, care, and com-mon sense. It is therefore essential to have personnelinvolved in the use and operation of equipment whoare competent, careful, physically and mentally quali-fied, and trained in the proper operation of the equip-ment and the handling of loads.Serious hazards include,but are not limited to, improper or inadequate mainte-nance,overloading, dropping or slipping of the load,obstructing the free passage of the load,and using equip-ment for a purpose for which it was not intended ordesigned.
The B30 Standard Committee fully realizes the impor-tance of proper design factors, minimum or maximumdimensions, and other limiting criteria of wire rope orchain and their fastenings, sheaves, sprockets, drums,and similar equipment covered by the standard, all ofwhich are closely connected with safety. Sizes,strengths,and similar criteria are dependent on many differentfactors,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 orother parts
(f) yenvironmental conditions causing corrosion orwear
(g) many variables that must be considered in eachindividual case The requirements and recommendations provided inthe volumes must be interpreted accordingly, and judg-ment used in determining their application.
