CMI CMI Health Effects & Remediation Safety 2 — Questions and Answers
Question 1: What does the term 'sick building syndrome' (SBS) refer to in the context of mold inspections?
- Acute health symptoms linked to time spent in a building without a specific identified cause (Correct answer)
- Legally confirmed mold contamination above EPA action levels
- A building where at least 50% of occupants have tested positive for mold antibodies
- A formal OSHA citation for inadequate ventilation
Correct answer: Acute health symptoms linked to time spent in a building without a specific identified cause
SBS describes a situation where building occupants experience acute health symptoms tied to time spent in the building, but no single contaminant has been definitively identified.
Question 2: Which fungi species is recognized as an opportunistic pathogen capable of causing invasive pulmonary aspergillosis in immunocompromised patients?
- Aspergillus fumigatus (Correct answer)
- Cladosporium cladosporioides
- Alternaria alternata
- Epicoccum nigrum
Correct answer: Aspergillus fumigatus
Aspergillus fumigatus is the leading cause of invasive aspergillosis, a life-threatening infection in immunocompromised individuals such as organ transplant recipients and chemotherapy patients.
Question 3: When decontaminating PPE after leaving a mold-contaminated area, what is the correct sequence of actions?
- Remove and bag disposable PPE in the work area, then wash hands thoroughly before touching face (Correct answer)
- Remove respirator first while still in the contaminated zone
- Wash PPE with water inside the work area and reuse immediately
- PPE decontamination is not required for non-toxic mold species
Correct answer: Remove and bag disposable PPE in the work area, then wash hands thoroughly before touching face
Disposable PPE should be removed and bagged within the work area to prevent cross-contamination, followed by thorough handwashing before touching the face or leaving.
Question 4: A mold inspector suspects Histoplasma capsulatum contamination in a crawl space. What unique precaution applies to this organism?
- Histoplasma is a dimorphic fungus that can cause systemic infection and requires enhanced respiratory protection (Correct answer)
- Histoplasma is non-pathogenic and requires no special precautions
- Histoplasma only affects those with mold allergies
- Standard inspection PPE is sufficient because it does not become airborne
Correct answer: Histoplasma is a dimorphic fungus that can cause systemic infection and requires enhanced respiratory protection
Histoplasma capsulatum is a dimorphic fungal pathogen found in bird and bat droppings that can cause histoplasmosis, a potentially serious systemic infection requiring enhanced respiratory protection.
Question 5: Which of the following best describes 'building-related illness' (BRI) as distinct from sick building syndrome?
- BRI involves a clinically diagnosed illness with an identified causative agent from the building (Correct answer)
- BRI is synonymous with sick building syndrome
- BRI requires at least 10 occupants to be simultaneously symptomatic
- BRI is only applicable to commercial buildings, not residential
Correct answer: BRI involves a clinically diagnosed illness with an identified causative agent from the building
Building-related illness is distinguished from SBS by the presence of a clinically recognized disease with a specific identified causative agent, such as Legionella or mold-related hypersensitivity pneumonitis.
Question 6: What is the recommended eye protection for a mold inspector entering a heavily contaminated area with potential for airborne spore release?
- Indirect-vent chemical splash goggles (Correct answer)
- Standard prescription eyeglasses only
- Safety glasses with side shields
- No eye protection is needed if a full-face respirator is not used
Correct answer: Indirect-vent chemical splash goggles
Indirect-vent chemical splash goggles provide a seal against the face and prevent spore entry from all directions, making them the appropriate choice for heavily contaminated environments.
