Under the workplace safety responsibilities the Class A safety program is built on, what is the employer’s core responsibility?

To provide a workplace free of recognized hazards, along with the training and protective equipment the work requires

Correct Incorrect Correct answer

To transfer all safety responsibility to employees once they have been given a copy of the written program and have signed an acknowledgment that they received and read it

Correct Incorrect Correct answer

To provide protective equipment only after an injury shows it was needed

Correct Incorrect Correct answer

To limit its role to investigating injuries after they occur

Correct Incorrect Correct answer

Your conservation reporting shows a large gap between water produced and water billed, but no one knows how much is leakage, meter error, or authorized unbilled use. Which program step do you order as executive?

A system water audit that separates real losses from apparent losses and authorized use, so conservation work is aimed at the losses that actually exist

Correct Incorrect Correct answer

A customer conservation campaign urging shorter showers, sized to close the entire gap, and credit all savings from the campaign against the gap whether or not the gap itself changes

Correct Incorrect Correct answer

A rate increase that recovers the cost of the unbilled water from billed customers

Correct Incorrect Correct answer

Replacement of every customer meter in the system before any audit is performed

Correct Incorrect Correct answer

During a compliance review, the executive finds one entry point where finished groundwater enters distribution is not represented in routine sampling records. What is the correct management response?

Backdate sampling records to cover the missing period so the file appears complete when the records are reviewed at the next inspection

Correct Incorrect Correct answer

Correct the sampling arrangement, document the gap and the fix, and verify the entry point is covered going forward

Correct Incorrect Correct answer

Average the results from other entry points and report them for this one

Correct Incorrect Correct answer

Remove the entry point from the system's facility list

Correct Incorrect Correct answer

You are approving the design of a fluoridation installation. Which design feature most directly limits how much fluoride chemical could ever reach the water in a feed malfunction?

A second bulk storage tank so more chemical can be kept on site

Correct Incorrect Correct answer

A day tank sized to hold only a small, bounded supply between bulk storage and the feeder

Correct Incorrect Correct answer

A larger feeder capable of delivering chemical at several times the normal rate before any further changes are made to the program

Correct Incorrect Correct answer

A longer feed line between the storage area and the injection point

Correct Incorrect Correct answer

Hydrant flow testing across the system is complete for the year. How should the Class A executive use the results at the system level?

File the results with the maintenance records for the year, note that the testing requirement has been satisfied, and take no further planning action from the readings

Correct Incorrect Correct answer

Direct retesting of every hydrant that flowed well, to confirm the favorable readings

Correct Incorrect Correct answer

Use the flow data to identify areas with deficient capacity and carry those areas into capital planning

Correct Incorrect Correct answer

Publish the readings to customers as evidence that every part of the system is adequate

Correct Incorrect Correct answer

Before committing a surface-water system to an alternative disinfectant, a Class A executive designs the pilot study. Which pilot design gives a defensible basis for the adoption decision?

Run the pilot for two weeks during the mildest raw-water conditions of the year, when the new process is most likely to perform at its best, as a standing practice for every system the executive oversees

Correct Incorrect Correct answer

Run the pilot only at average flow, because peak-flow and low-flow performance can be projected reliably from average-condition results

Correct Incorrect Correct answer

Judge the pilot on finished-water appearance and operator preference, because inactivation and by-product data take too long to accumulate

Correct Incorrect Correct answer

Run the pilot across the seasonal range of raw-water quality the plant actually faces, measuring inactivation performance and by-product formation throughout, before deciding on full-scale adoption

Correct Incorrect Correct answer

Why does the sampling program require chain-of-custody documentation?

It orders samples alphabetically for the analyst's convenience

Correct Incorrect Correct answer

It tracks each sample from collection through analysis so the result can be defended as belonging to that sample

Correct Incorrect Correct answer

It allows samples to be held indefinitely before analysis, in any container, without documenting who handled them during storage or transport

Correct Incorrect Correct answer

It replaces the need to label sample containers

Correct Incorrect Correct answer

An operator files a grievance claiming a supervisor applied the overtime roster unfairly. What is the best executive handling?

Listen to the grievance, investigate the roster records and the supervisor's account, decide on the facts, and answer the operator through the established process with the reasons

Correct Incorrect Correct answer

Deny the grievance immediately to support the supervisor's authority, without examining the roster records, hearing the supervisor's account of how the roster was applied, or giving the operator a chance to present supporting records

Correct Incorrect Correct answer

Grant the grievance immediately to end the complaint, without any investigation

Correct Incorrect Correct answer

Ask the operator to withdraw the grievance in exchange for extra overtime

Correct Incorrect Correct answer

A Class A executive oversees several systems whose chiefs sign monthly disinfection records. Which supervision system best protects the record?

Chiefs sign records as submitted, trusting each sampler completely and reviewing the underlying field results only if a problem is reported by a customer

Correct Incorrect Correct answer

The executive personally collects every residual sample at every system, so no chief's verification step is needed in the record chain of records

Correct Incorrect Correct answer

Chiefs verify field residual results before signing, and the executive spot-checks records and field results across systems on a set cycle

Correct Incorrect Correct answer

Records are reviewed only when a regulator asks for them, with no routine verification by chiefs or spot-checks by the executive's office during the year

Correct Incorrect Correct answer

A section has a cross-sectional area of 2.15 square feet and the water velocity is 3.1 ft/s. What is the flow in gallons per minute?

1,495.63 gpm

Correct Incorrect Correct answer

2,991.25 gpm

Correct Incorrect Correct answer

2,242.50 gpm

Correct Incorrect Correct answer

3,589.50 gpm

Correct Incorrect Correct answer

A system treats 2.15 MGD and applies a dose of 1.9 mg/L. How many pounds of chemical are fed per day?

34.07 lb/day

Correct Incorrect Correct answer

28.5 lb/day

Correct Incorrect Correct answer

40.85 lb/day

Correct Incorrect Correct answer

4.09 lb/day
