CHP CHP Equipment & Maintenance 1 — Questions and Answers
Question 1: What is the recommended frequency for replacing vacuum cleaner bags or emptying bagless canisters in a commercial housekeeping operation?
- Once per month
- When the bag is completely full
- Before the bag or canister exceeds two-thirds full (Correct answer)
- Once per week regardless of usage
Correct 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.
Question 2: Which type of floor machine is best suited for stripping old floor finish from a hard-surface floor?
- High-speed burnisher (1500–3000 RPM)
- Low-speed scrubber (175 RPM) with a black stripping pad (Correct answer)
- Dry vacuum with a hard floor attachment
- Steam mop
Correct 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.
Question 3: What does a Material Safety Data Sheet (SDS/MSDS) provide for cleaning chemicals?
- Pricing and vendor contact information
- Hazard information, safe handling instructions, and emergency response procedures (Correct answer)
- Recommended retail price and shelf life only
- Usage tips from the manufacturer
Correct 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.
Question 4: What is the correct procedure before performing maintenance or clearing a clog in a commercial vacuum cleaner?
- Keep it plugged in to maintain power
- Unplug the machine from the power source completely (Correct answer)
- Switch to the lowest power setting
- Wear only gloves, no other precautions needed
Correct 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.
Question 5: Which color pad is used on a floor buffer to apply floor finish (wax) without scratching?
- Black pad
- Red pad
- White or tan pad (Correct answer)
- Green pad
Correct 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.
Question 6: What maintenance task should be performed on a wet/dry vacuum after each use to prevent mold and bacterial growth?
- Oil the motor bearings
- Empty and rinse the tank, then leave the lid off to dry (Correct answer)
- Replace the filter after every use
- Apply a disinfectant spray to the exterior only
Correct 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.
