CHP CHP Equipment & Maintenance 2 — Questions and Answers
Question 1: What does the term 'dwell time' mean when using a disinfectant cleaning product?
- The time it takes to mix the chemical solution
- The length of time the chemical must remain wet on a surface to be effective (Correct answer)
- The shelf life of the product after opening
- The time between applications
Correct answer: The length of time the chemical must remain wet on a surface to be effective
Dwell time is the required contact time a disinfectant must remain wet on a surface to kill the stated pathogens on the product label.
Question 2: Which OSHA regulation requires lockout/tagout procedures for cleaning equipment service?
- 29 CFR 1910.132
- 29 CFR 1910.147 (Correct answer)
- 29 CFR 1910.1200
- 29 CFR 1910.134
Correct answer: 29 CFR 1910.147
OSHA 29 CFR 1910.147 (Control of Hazardous Energy) mandates lockout/tagout procedures to prevent unexpected equipment energization during maintenance.
Question 3: What is the purpose of color-coding cleaning cloths and mops in a professional housekeeping program?
- To match the hotel's brand colors
- To prevent cross-contamination between different areas such as bathrooms and bedrooms (Correct answer)
- To indicate cloth age and when to replace them
- To assign cloths to specific employees
Correct answer: To prevent cross-contamination between different areas such as bathrooms and bedrooms
Color-coding prevents cross-contamination by ensuring bathroom tools never come into contact with food-preparation or sleeping areas.
Question 4: How should a housekeeper properly dilute a concentrated cleaning chemical?
- Add concentrate to water to achieve the recommended dilution ratio (Correct answer)
- Add water to concentrate in the container
- Mix by shaking both together in any order
- Use undiluted for better cleaning results
Correct answer: Add concentrate to water to achieve the recommended dilution ratio
Always add concentrate to water (never water to concentrate) to prevent dangerous splashing reactions with highly caustic or acidic chemicals.
Question 5: What is the recommended ergonomic technique when pushing a loaded housekeeping cart to prevent back injury?
- Pull the cart behind you for better control
- Push the cart using body weight and legs rather than back muscles (Correct answer)
- Use one hand to push for speed
- Lean over the cart and use arms only
Correct answer: Push the cart using body weight and legs rather than back muscles
Pushing with body weight and leg muscles reduces strain on the lower back, which is the most common injury site for housekeeping staff.
Question 6: What maintenance schedule component helps prevent unplanned breakdowns of floor care equipment in large facilities?
- Reactive maintenance only after a breakdown occurs
- A preventive maintenance (PM) schedule with regular inspections and part replacements (Correct answer)
- Replacing equipment every 6 months regardless of condition
- Using equipment until failure, then servicing
Correct answer: A preventive maintenance (PM) schedule with regular inspections and part replacements
A preventive maintenance schedule identifies wear before failure occurs, extending equipment life and preventing costly operational downtime.
