What you'll learn
- Explain what hazardous energy is, how hazardous energy injuries happen and why control devices are not energy isolation
- Identify electrical, mechanical, hydraulic, pneumatic, gravitational, thermal and chemical energy sources and calculate stored energy in springs, raised loads, receivers, capacitors and flywheels
- Describe the scope and requirements of OSHA 29 CFR 1910.147, related OSHA standards, ANSI/ASSP Z244.1 and enforcement
- Explain the parts of an energy control program and the roles and training of authorized, affected and other persons
- Select appropriate locks, tags, hasps, valve, breaker and plug lockout devices and explain the limitations of tags
- Apply the eight-step lockout sequence from preparation to performing the work
- Verify a zero energy state using the try step, gauges and live-dead-live testing, and control each type of stored energy
- Organize group lockouts, shift change transfers and contractor coordination so that every exposed worker keeps personal control
- Restore equipment safely, manage testing and positioning, and follow abandoned lock removal procedures
- Explain the minor servicing, cord-and-plug and other exceptions and the role of alternative methods under ANSI/ASSP Z244.1
- Write and maintain machine-specific procedures and placards and plan periodic inspections and program audits
- Analyze hazardous energy incidents and draft a machine-specific procedure for a multi-source machine
