ASCS ASCS Project Planning & Documentation 1 — Questions and Answers
Question 1: What document is typically used to outline the scope of work before an air duct cleaning project begins?
- Work order or scope of work agreement (Correct answer)
- Material Safety Data Sheet
- OSHA 300 log
- EPA audit report
Correct answer: Work order or scope of work agreement
A work order or scope of work agreement defines project boundaries, tasks, and expectations prior to beginning duct cleaning.
Question 2: According to NADCA standards, how should pre-project inspections be documented?
- With written notes and photographic evidence (Correct answer)
- Verbally communicated to the client only
- On a standard OSHA form
- Through a building permit application
Correct answer: With written notes and photographic evidence
NADCA requires written notes combined with photographic or video evidence to create a verifiable record of pre-job conditions.
Question 3: Which of the following is a key reason for performing a pre-project system assessment?
- To identify access points, contamination levels, and special hazards (Correct answer)
- To obtain a building permit
- To calculate employee overtime
- To order replacement ductwork
Correct answer: To identify access points, contamination levels, and special hazards
A pre-project assessment identifies where workers will access the system, what contaminants are present, and any hazards requiring special precautions.
Question 4: What information should be recorded during a post-cleaning verification inspection?
- Evidence of cleanliness, photos, and any deficiencies noted (Correct answer)
- Only the customer's signature
- Equipment serial numbers only
- The HVAC brand and model only
Correct answer: Evidence of cleanliness, photos, and any deficiencies noted
Post-cleaning verification should document evidence of cleanliness through photos and note any deficiencies to ensure the work meets NADCA standards.
Question 5: Which NADCA standard defines the assessment, cleaning, and restoration of HVAC systems?
- NADCA ACR (Assessment, Cleaning, and Restoration of HVAC Systems) (Correct answer)
- ASHRAE 62.1
- EPA 402-K-93-007
- OSHA 29 CFR 1910.134
Correct answer: NADCA ACR (Assessment, Cleaning, and Restoration of HVAC Systems)
The NADCA ACR standard is the industry benchmark document outlining requirements for assessing, cleaning, and restoring HVAC systems.
Question 6: Why is it important to document the location of all access panels created during a duct cleaning project?
- So they can be properly resealed and the system is returned to original condition (Correct answer)
- To comply with fire marshal requirements only
- To bill the client for extra panels
- To determine airflow calculations
Correct answer: So they can be properly resealed and the system is returned to original condition
Documenting access panel locations ensures every panel is properly resealed, restoring system integrity and preventing air leakage.
