  1. When performing a Job Hazard Analysis (JHA) for high-pressure steam pipe installation, which step should be completed FIRST?

    Answer: Break the job into sequential steps

    A JHA begins by breaking the job into distinct sequential steps before hazards within each step can be identified.

  2. A pipefitter notices a small drip from a threaded connection on a live steam line rated at 150 psi. What is the MOST appropriate immediate action?

    Answer: Isolate the line using lockout/tagout procedures before repairs

    Live steam leaks must be addressed by isolating the line through LOTO before any repair work to prevent burn injuries.

  3. Which hierarchy of controls method is considered MOST effective at reducing occupational hazards?

    Answer: Elimination of the hazard

    Elimination removes the hazard entirely and is the most effective level of the hierarchy of controls.

  4. A confined space in a steam plant has an oxygen reading of 19.0%. How should this space be classified?

    Answer: Oxygen-deficient; atmosphere-supplying respirator required

    OSHA defines oxygen-deficient atmospheres as less than 19.5%; entry requires supplied-air or SCBA equipment.

  5. What does the term 'residual risk' mean in the context of steamfitter safety planning?

    Answer: The risk that remains after all control measures have been applied

    Residual risk is what remains after implementing all feasible controls, and it must be communicated to workers.

  6. During a risk matrix evaluation, a hazard is rated as 'Likely' in probability and 'Critical' in severity. What risk level does this typically produce?

    Answer: High risk — immediate corrective action required

    A 'Likely' × 'Critical' combination places the hazard in the high-risk zone requiring immediate corrective action.

  7. Which regulation requires employers to develop a written energy control (lockout/tagout) program for steamfitting operations?

    Answer: OSHA 29 CFR 1910.147

    OSHA 29 CFR 1910.147, 'Control of Hazardous Energy,' mandates written LOTO programs for equipment with hazardous energy sources.
