DEVELOPMENT OF LOTO DEVICES FOR MINIATURE BREAKER ON CDU ELECTRICAL CONTROL PANEL BY USING 3D PRINTING TECHNOLOGY

Abstract

Lockout/tagout is a method employed to prevent equipment from moving and posing a risk to workers. The lockout/tagout standard is applicable to various industries and covers the servicing and maintenance of machines and equipment where unexpected start-up or release of stored energy could potentially result in severe damage or even fatalities. Insufficient control of hazardous energies can lead to grave injuries or fatalities for workers involved in servicing or maintaining machinery and equipment. Failure to properly control hazardous energies during maintenance tasks can result in serious or catastrophic injuries, including electrocution, burns, crushes, cuts, lacerations, amputations, or fractures. Furthermore, to properly control hazardous energies by implementing the lockout/tagout involves several steps. Before start, make sure familiar with the safety regulations and standards in working area, as well as the specifics of the equipment and always make sure to follow the specific instructions provided with the lockout/tagout procedures. In this study, the development of Lockout/Tagout (LOTO) devices for the miniature breaker on the CDU electrical control panel by using 3D printing technology was successful. The objective was to enhance safety measures during maintenance and repair work by preventing accidental activation.
