Confined Spaces and Lockout/Tagout practice questions for the CSP exam

A maintenance crew is assigned to clear a jam from a conveyor. The main disconnect on the conveyor is a type that has a hasp and can accept a padlock. The supervisor proposes using only a tag on the disconnect because it is faster. Under the standard, what must the employer's energy control program do?

1. A.Utilize lockout, unless the employer can demonstrate that a tagout system will provide full employee protection
2. B.Utilize lockout only if the equipment has been modified since the standard took effect
3. C.Utilize tagout whenever the servicing is expected to last less than one shift
4. D.Utilize tagout, because tags are acceptable whenever a supervisor approves them

During a periodic inspection of a conveyor line's lockout/tagout procedure, the inspector observes that a maintenance mechanic skipped a required step when isolating the equipment. The employee's training records are current and were completed six months ago. What does the standard require the employer to do?

1. A.Conduct additional retraining, because the inspection revealed deviations in the employee's use of the energy control procedures
2. B.Reassign the lockout duties to an affected employee who has not been observed deviating
3. C.Wait until the next annual inspection to determine whether retraining is warranted
4. D.Take no action, because the training certification is current and records are up to date

A crew is preparing to enter a process vessel for cleaning. The agitator motor has been locked out, and a blind has been installed in the corrosive feed line. A second line carrying a toxic solvent is still connected to the vessel and is controlled only by one closed valve. The supervisor wants the vessel to be completely protected against the release of energy and material into the space before entry. Which action is needed to finish isolating the vessel?

1. A.Place a double block and bleed system on the solvent line, or blank or blind it
2. B.Run continuous forced-air ventilation in the vessel during the entry
3. C.Station an attendant at the opening to call out if solvent begins to flow
4. D.Have the entrants carry a gas monitor to detect solvent vapor if the valve leaks
