Steamfitter Risk Assessment and Mitigation 2

Question 1

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

Accepted Answer

Break the job into sequential steps

Answer

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

Question 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?

Accepted Answer

Isolate the line using lockout/tagout procedures before repairs

Answer

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

Question 3

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

Accepted Answer

Elimination of the hazard

Answer

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

Question 4

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

Accepted Answer

Oxygen-deficient; atmosphere-supplying respirator required

Answer

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

Question 5

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

Accepted Answer

The risk that remains after all control measures have been applied

Answer

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