SECTION X:ADDITIONAL GUIDANCE
The equipment covered by the B30 Standard is subjectto hazards that cannot be abated by mechanical means, butonly by the exercise of intelligence, care, and commonsense. It is therefore essential to have personnel involvedin the use and operation of equipment who are competent,careful, physically and mentally qualified, and trained inthe proper operation of the equipmentand the handling ofloads. Serious hazards include, but are not limited to,improper or inadequate maintenance, overloading. drop-ping or slipping of the load, obstructing the free passage ofthe load, and using equipment for a purpose for which itwas not intended or designed.
The B30 Standards 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
