Chapter 3

Energy control procedures

The fundamental goal of any safety program is to ensure that workers are not exposed to sources of energy such as high-voltage electricity, high-temperature fluids, toxic chemicals, moving parts, or falls from heights. Therefore, before working on a piece of equipment, the associated sources of high energy must be identified and secured. This chapter discusses the techniques for identifying and controlling sources of high energy. Topics covered include minimizing contact with air, isolation, lockout/tagout, work permits, confined space entry, hot tapping and the clearing of plugged lines.
