✍️ Sample CPR Questions & Answers
1. What is the primary purpose of calculating the number of air changes per hour (ACH) during a drying project?
ACH determines whether the air movers are circulating enough air volume to effectively move moisture from wet surfaces into the air stream for dehumidifier extraction.
2. During a water damage job, a restorer encounters Category 3 (black water) contamination. What level of skin protection is required?
Category 3 water contains pathogenic organisms; full body coverage with a sealed Tyvek suit, chemical-resistant gloves, and waterproof boots is required to prevent skin contact.
3. A restoration employee has a claustrophobia concern that may affect respirator use. The proper action is to:
OSHA requires a medical evaluation by a licensed healthcare professional (PLHCP) to determine if any medical condition, including claustrophobia, prevents safe respirator use.
4. Which cleaning method is most appropriate for removing soot from a delicate porcelain figurine after a fire loss?
Ultrasonic cleaning uses high-frequency sound waves in a liquid bath to gently dislodge soot from delicate and intricate items without mechanical abrasion.
5. What is the importance of sealing off contaminated areas during remediation?
Sealing off contaminated areas, often through containment barriers like plastic sheeting and negative air pressure, is a critical step in remediation, especially for mold, asbestos, or hazardous materials. This isolation prevents airborne contaminants, spores, or harmful particles from migrating to unaffected parts of the building, protecting both the occupants and the clean areas from cross-contamination. It ensures that the remediation efforts are localized and effective without spreading the problem.
6. What is the purpose of 'dehumidification' versus 'evaporation' in structural drying?
Evaporation moves moisture from wet materials into the air, and dehumidification then extracts that airborne moisture to maintain vapor pressure differential and continue drying.
