Hot Work and Welding questions for the ASP

Question 1

A welder needs to weld a bracket onto a steel wall panel in a plant area not designed for hot work. The panel is bare, uncovered sheet steel. On the other side of the wall, a stack of cardboard cartons sits against the panel. The supervisor cannot relocate the cartons before the job must start. Which action does the standard require for this job to proceed?

1. AProvide a fire watch on the opposite side of the wall from the work
2. BShut down the ducts and conveyor systems in the area
3. CDo not weld, because welding is prohibited on any metal wall that has combustibles behind it
4. DInstall fire-resistant shields only on the welder's side of the wall

Question 2

A maintenance crew at a food-processing plant needs to weld a bracket onto a steel roof support. The support is in a mezzanine storage area that has never been designated for cutting or welding. The area has stacked cardboard packaging. The maintenance supervisor says the welder is experienced and can simply start, since no one else is available to review the job. Under the standard, what must happen before the welding proceeds?

1. AThe work may proceed if the supervisor alone accepts responsibility, since supervisors are responsible for safe use of the process
2. BThe welder's own judgment is sufficient, because experienced welders may self-authorize hot work in any area of the plant
3. CThe work may proceed once the cardboard is covered, because designated hot work areas are only needed for pipe welding
4. DThe individual management has designated to authorize cutting and welding in areas not specifically designed for such work must authorize the operation

Question 3

A welder must cut brackets inside a small ballast tank, which is a confined space. The tank has no openings that allow mechanical ventilation to be set up, so adequate ventilation to prevent toxic accumulation cannot be provided. Air monitoring shows the atmosphere is not immediately hazardous to life. Which respiratory protection approach does the standard require for the welder?

1. ANatural ventilation through the manhole alone, because the atmosphere is not immediately hazardous to life
2. BReleasing oxygen from a cylinder into the tank to dilute the fumes and prevent oxygen deficiency
3. COnly a full-facepiece, pressure-demand self-contained breathing apparatus, because the space is confined
4. DA NIOSH-approved airline respirator or hose mask
