Safety, Environmental Compliance, and Regulatory Requirements
Core concepts
Understand permit-to-work, lockout/tagout, confined-space entry, hot-work permits, and energy isolation. Know the hazards specific to turbines: high-pressure steam, rotating equipment, hot surfaces, noise, and stored hydraulic energy. Candidates must recognize environmental controls: emissions limits for gas turbines, water discharge and thermal limits for cooling systems, oil and chemical spill prevention, and noise regulation. Know the purpose of environmental monitoring and recordkeeping, and the meaning of exceeding a permit limit - report, investigate, and correct.
Traps
Questions often test whether a procedure requires a permit or merely notification. Another trap is assuming a trip or shutdown removes all energy: stored pressure, hydraulic accumulators, and residual heat remain. Remember that environmental exceedance reporting is usually time-bound and mandatory, not discretionary.
Worked rule of thumb
Apply the hierarchy of control: eliminate, substitute, engineer, administrate, then PPE last. If a question offers PPE as the only control for a high-energy hazard, look for a better engineered answer.
Exam focus
Be ready to identify the correct permit, the correct isolation boundary, and the correct reporting action for an exceedance.
