The two main systems used to classify these hazardous areas are the Class/Division system and the Zone system. Hazardous energy is any form of power—electrical, mechanical, stored, hydraulic, pneumatic, chemical, thermal, or even gravity—that can unexpectedly release and harm workers during equipment servicing or maintenance. OSHA's Control of Hazardous Energy (Lockout/Tagout) standard (29 CFR 1910. 147). of work for the project. The objective of a HAC analysis is to minimize uncontrolled ignition by electrical equipment or hot surfaces of flammables in air that could lead to fires or explosions resulting in equipment and propert nition source controls of varying degrees. hazardous area classification or “HAC” assessment is used to identify and document areas. This Technical Measures Document refers to the classification of plant into hazardous areas, and the systematic identification and control of ignition sources The relevant Level 2 Criteria are 5.
