ABSTRACT
Some of the case histories revealed that confined space entrants can be killed or injured when hazardous liquids and gases leak into a space through attached pipes. This chapter describes the principle of lockout/tagout, yet the actual implementation of a comprehensive lockout/tagout program is far more complicated. Specific provisions that lockout/tagout programs must include are dictated by a comprehensive Occupational Safety and Health Administration (OSHA) standard. The chapter explains the requirements of that standard and describes how they may be integrated into a confined space entry program. The standard stipulates that a six step procedure must be followed when implementing lockout or tagout. Shift work presents an interesting situation since continuity of lockout/tagout must be assured at all times. Lockout is the preferred method of hazard control and must be employed unless an employer can demonstrate that his tagout procedures provide a level of protection equal to lockout.
