The ASME B30 Standard contains provisions that apply to the construction, installation, operation, inspec- tion, testing, maintenance, and use of cranes and other lifting and material-movement related equipment. For the convenience of the reader, the Standard has been divided into separate volumes. Each volume has been written under the direction of the ASME B30 Standard Committee and has successfully completed a consensus approval process under the general auspices of the American National Standards Institute (ANSI).

SECTION X: ADDITIONAL GUIDANCE
The equipment covered by the B30 Standard is subject to 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 personnel involved in the use and operation of equipment who are competent, careful, physically and mentally quali- fied, and trained in the proper operation of the equip- mentand the handling ofloads. Serious hazards include, but are not limited to, improper or inadequate mainte- nance, overloading, dropping or slipping of the load, obstructingthe free passageofthe load, and usingequip- ment for a purpose for which it was not intended or designed. The B30 Standard Committee fully realizes the impor- tance of proper design factors, minimum or maximum dimensions, and other limiting criteria of wire rope or chain and their fastenings, sheaves, sprockets, drums
