While decanting a water-based alkaline cleaner, a technician gets a splash in one eye. An emergency eyewash is within reach, and a coworker is nearby. Identify the immediate priority.
Correct answer: D - Start flushing at the eyewash while the coworker retrieves the product's first-aid instructions.
During an approved rodent-cleanup task, a crew wearing the specified PPE finds dried mouse droppings on a sound metal shelf. The crew usually begins loose-soil removal with a HEPA vacuum. For these deposits, the initial sequence is:
Correct answer: B - Wet with the appropriate disinfectant, allow its required contact time, then wipe up.
A pinless moisture meter reads high along a narrow strip of a veneered cabinet. An infrared image shows the strip cooler than nearby wood, and a metal brace sits directly behind it. What would resolve whether the panel is actually wet?
Correct answer: C - A material-appropriate moisture check accounting for the metal brace.
A receiving log contains 48 scans against a manifest of 48 cartons. One expected carton was scanned twice, and one scan belongs to another customer's carton. Every other scanned identifier is distinct and matches the manifest; no cartons were diverted or otherwise accounted for. Select the correct reconciliation, recording the foreign carton separately.
Correct answer: B - 46 distinct expected cartons matched; 2 expected cartons remain unresolved.
A clean, dry wool shawl is stable and approved for tissue wrapping. Available supplies include acid-free tissue with an alkaline reserve and neutral-pH tissue without one. Which choice suits the fiber?
Correct answer: C - Neutral-pH tissue with no added alkaline reserve.
A truck develops an engine fault during a scheduled stop on a pack-back journey. A supervisor approves a suitable replacement truck and driver. The load is secure, and its carton identities and condition match the dispatch record. Before the replacement leaves, the crew should:
Correct answer: A - Add the new driver, vehicle and custody handoff to the existing shipment record.
A quaternary-ammonium disinfection process develops low active-concentration readings in liquid expressed from its wiping cloths. Fresh solution meets specification, and the product, dilution and water source are unchanged. The problem began when approved wipes were replaced with cotton cloths. Which correction addresses the most likely cause?
Correct answer: A - Restore the compatible wiping material; cotton can bind the quat.
Two inconspicuous areas of a sound lacquered cabinet undergo cleaning trials with the same cleaner, dilution, temperature and contact time. A stiff brush removes the smoke film but dulls the coating. A soft pad removes the film without changing the gloss. The procedure selected for the remaining surfaces should:
Correct answer: A - Use the soft pad with the tested cleaner.
An odor investigation finds that cleaned, dry metal ornaments are odor-free individually. Odor returns when they are enclosed in their original fire-exposed carton, but not when the check is repeated with unused packaging. These comparisons most strongly support:
Correct answer: B - Replacing the original carton and repeating the odor check.
A cleaned shelf passes its specified ATP test. Its required disinfection process was completed as specified and documented, and all other agreed release checks have passed. Which statement accurately describes the acceptance evidence?
Correct answer: D - Checks passed; ATP does not demonstrate sterility.
