Plant Operations Practice Questions for Level 3 · Advanced

1. Question 1

   A plant will begin using a new polymer next week. The product has different hazards than the current polymer, and the new SDS has arrived. What should the supervisor do before operators use it?

   1. File the SDS and wait for annual training
   2. Use the supplier label as the operator training
   3. Update the hazard-communication program and train affected operators
   4. Store the first delivery separately until operators learn the hazards during use
   Show the answer

   Answer: C. Update the hazard-communication program and train affected operators

   Affected operators need the new hazard information and training before working with the chemical.

2. Question 2

   A chemical-transfer hose ruptures and releases an unknown amount of ferric chloride. The spill is moving toward a floor drain. The operator is not trained or equipped for spill response. What should the operator do first?

   1. Withdraw, warn others away, and activate the plant chemical-response plan
   2. Build a temporary dike with available absorbent material
   3. Wash the spill toward the designated chemical-waste sump
   4. Close the floor drain while another operator stops the leaking hose
   Show the answer

   Answer: A. Withdraw, warn others away, and activate the plant chemical-response plan

   An untrained and unequipped operator should keep people away and activate the established response plan rather than approach the release.

3. Question 3

   During an evacuation drill, two contractors report to the wrong assembly area and cannot be accounted for promptly. The review finds that no one was assigned to check contractors against the site sign-in list. What is the best correction?

   1. Use the employee headcount total to account for everyone on site
   2. Have each contractor report departure to their company supervisor after leaving the plant
   3. Have the entry-gate attendant count vehicles leaving during an evacuation
   4. Assign contractor roll-call responsibility and verify it in another drill
   Show the answer

   Answer: D. Assign contractor roll-call responsibility and verify it in another drill

   The drill identified an unassigned contractor-accountability duty. Assigning that responsibility and testing it again directly corrects the gap.

4. Question 4

   A vulnerability review finds that several former employees still have active remote-access accounts for the plant control network. No unauthorized changes are found. What should be done first?

   1. Keep the accounts active until the scheduled annual security review
   2. Disable the old accounts and review recent access records
   3. Change the shared operator password
   4. Disable all remote access, including current approved vendor support
   Show the answer

   Answer: B. Disable the old accounts and review recent access records

   Access that is no longer authorized should be removed, and the account records should be checked for unexpected use.

5. Question 5

   An operator is assigned work that requires a tight-fitting respirator. The operator completed respirator training but has not received a medical evaluation or fit test. What must happen first?

   1. Complete the fit test using the assigned respirator model
   2. Use the respirator for only part of the scheduled work period
   3. Complete the medical evaluation required for respirator use
   4. Have another trained operator continuously observe the respirator user
   Show the answer

   Answer: C. Complete the medical evaluation required for respirator use

   The required medical evaluation must be completed before fit testing or required respirator use.
