CDA Risk Assessment & Mitigation 2 — Questions and Answers
Question 1: A decorative artist is working with oil-based glazes indoors. Which ventilation strategy BEST mitigates the risk of VOC buildup?
- Open one window on the leeward side only
- Use cross-ventilation with intake and exhaust airflow plus an air purifier rated for organic vapors (Correct answer)
- Run a ceiling fan on low speed
- Place a bowl of baking soda near the work area
Correct answer: Use cross-ventilation with intake and exhaust airflow plus an air purifier rated for organic vapors
Cross-ventilation combined with an organic-vapor air purifier actively removes VOCs rather than simply diluting them.
Question 2: Which PPE item is most critical when spray-applying solvent-based metallic paint in an enclosed studio?
- Safety glasses only
- Nitrile gloves only
- A half-face respirator with OV/P100 cartridges (Correct answer)
- A standard dust mask (N95)
Correct answer: A half-face respirator with OV/P100 cartridges
An OV/P100 respirator protects against both organic vapor inhalation and particulate matter from spray atomization.
Question 3: Before applying decorative faux finish on an older home's walls, what is the primary risk assessment step regarding the existing paint?
- Test for lead content using an EPA-approved test kit (Correct answer)
- Check the color with a spectrophotometer
- Measure the wall's moisture content only
- Sand a small patch and observe the dust color
Correct answer: Test for lead content using an EPA-approved test kit
Homes built before 1978 may have lead-based paint, and disturbing it without testing violates EPA RRP rules and creates serious health hazards.
Question 4: A client is allergic to latex. Which risk mitigation step should a decorative artist take when planning a mural project?
- Use latex paints but apply them before the client arrives
- Switch entirely to acrylic-free mineral paints
- Select latex-free paint formulations and document the substitution in the project plan (Correct answer)
- Add a latex neutralizer to standard latex paint
Correct answer: Select latex-free paint formulations and document the substitution in the project plan
Selecting latex-free products and documenting the choice protects the client and provides a record of due diligence.
Question 5: When using a heat gun to strip a decorative finish, the PRIMARY fire risk comes from:
- The heat gun's power cord overheating
- Ignition of stripped flakes or nearby combustible materials (Correct answer)
- Excess heat warping the wall substrate
- Static electricity buildup on the work surface
Correct answer: Ignition of stripped flakes or nearby combustible materials
Stripped paint flakes and rags soaked in finish residue are highly combustible and can ignite from heat gun exhaust.
Question 6: Which ergonomic risk is MOST common for decorative artists performing detailed brushwork at an easel for extended periods?
- Lower back strain from improper chair height
- Repetitive strain injury in the wrist, forearm, and shoulder (Correct answer)
- Eye strain from insufficient ambient light only
- Knee injury from standing on hard floors
Correct answer: Repetitive strain injury in the wrist, forearm, and shoulder
Repetitive fine motor movements with a brush cause cumulative trauma to the wrist, forearm tendons, and shoulder rotator cuff.
Question 7: A decorative artist stores linseed oil-soaked rags in a sealed metal can overnight. Why is this the correct practice?
- To prevent the rags from drying out for reuse
- To contain spontaneous combustion risk by limiting oxygen (Correct answer)
- To comply with municipal recycling regulations
- To preserve the oil content for later thinning
Correct answer: To contain spontaneous combustion risk by limiting oxygen
Linseed oil oxidizes exothermically; a sealed metal container limits oxygen and prevents the heat buildup that causes spontaneous combustion.
