CEAC Environmental Modification & Accessibility Design 2 — Questions and Answers
Question 1: Under ADA Standards, what is the maximum slope for an accessible route in a site arrival area?
- 1:12 (8.33%)
- 1:16 (6.25%)
- 1:20 (5%) (Correct answer)
- 1:10 (10%)
Correct answer: 1:20 (5%)
Accessible routes must not exceed 1:20 (5%) slope; steeper slopes are ramps requiring handrails and landings.
Question 2: A grab bar installed in a bathtub transfer configuration must support a minimum static load of:
- 150 lbs
- 200 lbs
- 250 lbs (Correct answer)
- 300 lbs
Correct answer: 250 lbs
ADA and ICC A117.1 require grab bars to withstand a minimum 250-pound static load in any direction.
Question 3: When modifying a doorway for wheelchair access, the minimum clear width required by ADA Standards is:
- 28 inches
- 30 inches
- 32 inches (Correct answer)
- 36 inches
Correct answer: 32 inches
ADA requires a minimum 32-inch clear opening width measured between the face of the door and the opposite stop when the door is open 90 degrees.
Question 4: In an accessible kitchen modification, what is the maximum height for a reach range to a side-approach shelf?
- 44 inches
- 46 inches
- 48 inches (Correct answer)
- 54 inches
Correct answer: 48 inches
ADA Standards set the maximum high side reach at 48 inches above the floor for a side approach.
Question 5: Which flooring characteristic is MOST critical when selecting materials for a dementia-accessible environment?
- High gloss finish to reflect light
- High contrast pattern between floor and walls
- Low-contrast, non-patterned surface to reduce spatial confusion (Correct answer)
- Raised texture for tactile wayfinding
Correct answer: Low-contrast, non-patterned surface to reduce spatial confusion
High-contrast or busy patterns can cause perceptual disturbances in individuals with dementia; low-contrast uniform flooring reduces confusion.
Question 6: A CEAC consultant is assessing a home for a client with low vision. What minimum illumination level is recommended for task areas such as kitchen counters?
- 10 foot-candles
- 30 foot-candles
- 50 foot-candles (Correct answer)
- 100 foot-candles
Correct answer: 50 foot-candles
Task areas for individuals with low vision typically require a minimum of 50 foot-candles to ensure adequate visibility for detailed activities.
Question 7: When installing a vertical platform lift (wheelchair lift) in a residential setting, which code primarily governs its safety requirements in the US?
- ASME A17.1 (Safety Code for Elevators and Escalators)
- ASME A18.1 (Safety Standard for Platform Lifts and Stairway Chairlifts) (Correct answer)
- ICC A117.1 Accessibility Standard
- NFPA 101 Life Safety Code
Correct answer: ASME A18.1 (Safety Standard for Platform Lifts and Stairway Chairlifts)
ASME A18.1 governs vertical platform lifts and stairway chairlifts in the United States, covering construction, installation, and inspection.
