CHP Equipment & Maintenance Flashcards

What is the recommended frequency for replacing vacuum cleaner bags or emptying bagless canisters in a commercial housekeeping operation?

Answer: Before the bag or canister exceeds two-thirds full

Vacuums lose suction power significantly when containers exceed two-thirds capacity, reducing cleaning effectiveness and straining the motor.

Which type of floor machine is best suited for stripping old floor finish from a hard-surface floor?

Answer: Low-speed scrubber (175 RPM) with a black stripping pad

A low-speed floor machine at 175 RPM paired with an abrasive black stripping pad is specifically designed to remove old wax or floor finish.

What does a Material Safety Data Sheet (SDS/MSDS) provide for cleaning chemicals?

Answer: Hazard information, safe handling instructions, and emergency response procedures

An SDS provides comprehensive hazard information including health risks, safe handling, storage requirements, and emergency response procedures.

What is the correct procedure before performing maintenance or clearing a clog in a commercial vacuum cleaner?

Answer: Unplug the machine from the power source completely

Always unplug electrical equipment before performing any maintenance or clearing blockages to prevent electric shock or accidental start-up.

Which color pad is used on a floor buffer to apply floor finish (wax) without scratching?

Answer: White or tan pad

White or tan pads are the least abrasive and are used for applying floor finish and light buffing without scratching the floor surface.

What maintenance task should be performed on a wet/dry vacuum after each use to prevent mold and bacterial growth?

Answer: Empty and rinse the tank, then leave the lid off to dry

Emptying, rinsing, and air-drying the tank after each use prevents moisture buildup that leads to mold, bacteria, and unpleasant odors.
