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 Standards Committee fully realizes theimportance of proper design factors, minimum or maxi-mum dimensions,and other limiting criteria of wirerope 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 manydifferent factors, often varying with the installation anduses. These factors depend on the condition of theequipment or material; on the loads; on the acceleration
