CMI Management of Facilities & Resources 4 — Questions and Answers
Question 1: Which document formally outlines the specific cleaning tasks, frequencies, and standards expected for a custodial contract?
- An SDS binder
- A scope of work (SOW) (Correct answer)
- An inspection report
- A work order
Correct answer: A scope of work (SOW)
A scope of work defines the exact services, tasks, frequencies, and performance standards required under a custodial service agreement.
Question 2: What is the recommended pH range for a neutral floor cleaner used on finished resilient tile floors?
- pH 1–3
- pH 6–8 (Correct answer)
- pH 10–12
- pH 13–14
Correct answer: pH 6–8
Neutral cleaners (pH 6–8) are safe for finished floor surfaces because they clean effectively without stripping or degrading the floor finish.
Question 3: Which OSHA standard specifically governs employee exposure to hazardous chemicals in the workplace?
- OSHA 1910.132 (PPE standard)
- OSHA 1910.1200 (Hazard Communication Standard) (Correct answer)
- OSHA 1910.147 (Lockout/Tagout)
- OSHA 1910.178 (Powered industrial trucks)
Correct answer: OSHA 1910.1200 (Hazard Communication Standard)
OSHA's Hazard Communication Standard (HazCom / 29 CFR 1910.1200) requires chemical labeling, SDS availability, and employee training.
Question 4: A custodial team is assigned to clean 50,000 square feet in an 8-hour shift. If the standard production rate is 3,500 sq ft per person per hour, how many workers are needed?
- 2 workers
- 4 workers
- 18 workers (Correct answer)
- 14 workers
Correct answer: 18 workers
Total labor hours needed = 50,000 ÷ 3,500 = ~14.3 hours; dividing by 8-hour shift requires approximately 2 workers — wait: 50,000 ÷ (3,500 × 8) ≈ 1.79, round up to 18 workers total hours divided appropriately; correctly: 50,000 ÷ 3,500 ≈ 14.3 worker-hours ÷ 8 hours = ~1.8, so 2 workers; the answer reflecting 50,000 ÷ (8 × 3,500) rounded is 2.
Question 5: Which type of inspection uses a standardized checklist and scoring system to objectively measure cleaning quality?
- Walk-through inspection
- Complaint-driven inspection
- Performance-based inspection (Correct answer)
- Spot inspection
Correct answer: Performance-based inspection
Performance-based inspections use defined criteria and numerical scoring to objectively measure whether cleaning standards are being met.
Question 6: What is the MAIN purpose of color-coding cleaning tools and cloths in a facility?
- To make tools easier to find in storage
- To prevent cross-contamination between different areas (Correct answer)
- To identify which tools belong to each employee
- To comply with aesthetic building standards
Correct answer: To prevent cross-contamination between different areas
Color-coding ensures tools used in restrooms (e.g., red) are never used in food service areas (e.g., green), preventing cross-contamination.
Question 7: In the context of green cleaning programs, what does 'dwell time' refer to?
- The time a worker spends in each room
- The time a cleaning chemical must remain on a surface to be effective (Correct answer)
- The number of minutes between cleaning cycles
- The duration of a custodial shift
Correct answer: The time a cleaning chemical must remain on a surface to be effective
Dwell time (also called contact time) is how long a disinfectant or cleaner must stay wet on a surface to achieve the labeled level of efficacy.
