Read the first 7 Risk Assessment and Mitigation flashcards as text

  1. When steam piping is first pressurized after installation or repair, why is a slow, controlled warm-up procedure a critical risk mitigation step?

    Answer: To prevent thermal shock and condensate water hammer as cold pipe heats gradually

    Slow warm-up allows condensate to drain and pipe metal to expand uniformly, preventing thermal shock, water hammer, and joint failure.

  2. A change order requires routing a new steam line through a previously unplanned wall penetration in a fire-rated assembly. What risk must be assessed and mitigated?

    Answer: Compromising the fire-rated wall assembly, requiring listed firestop systems

    Penetrations through fire-rated assemblies must be sealed with tested and listed firestop systems to maintain the fire barrier's integrity.

  3. Which leading indicator is MOST useful for proactively measuring safety risk on a steamfitting job site?

    Answer: Number of near-miss events reported in the current period

    Near-miss reporting is a leading indicator because it identifies hazards before injuries occur, enabling proactive corrective action.

  4. A steamfitter must grind pipe flanges using an angle grinder. Which combination of PPE best mitigates the specific risks of this task?

    Answer: Face shield over safety glasses, hearing protection, and cut-resistant gloves

    Grinding creates flying sparks and metal fragments (face shield + glasses), high noise (hearing protection), and abrasion hazards (cut-resistant gloves).

  5. What is the MAIN purpose of a Management of Change (MOC) process in a steam plant where piping modifications are made?

    Answer: To ensure all safety, operational, and design impacts of a change are reviewed before implementation

    MOC ensures that proposed changes are systematically reviewed for new hazards, regulatory compliance, and operational impacts before work begins.

  6. During a hydrostatic pressure test on a new steam line, the system fails to hold pressure. What is the SAFEST way to locate the leak?

    Answer: Depressurize the system to zero before inspecting fittings and joints

    Depressurizing to zero before inspection is mandatory; pressurized water under hydrotest conditions can cause serious injection or impact injuries.

  7. A risk assessment identifies that a steamfitter will be exposed to elevated noise levels of 92 dBA for a full 8-hour shift. Under OSHA 29 CFR 1910.95, which action is required?

    Answer: Enroll the worker in a Hearing Conservation Program including monitoring, audiometric testing, and hearing protection

    OSHA's Hearing Conservation Amendment requires a hearing conservation program when noise exposure equals or exceeds 85 dBA as an 8-hour TWA.
