Operable Parts, Reach Ranges, Routes, Protruding Objects, Alarms and Signs (2010 ADA Standards)
2010 ADA Standards for Accessible Design as published on ada.gov (read 2026-09-19); DBPR reference list item 7 'Americans with Disability Act' · Reviewed 2026-09-21
"Life Safety and Americans with Disabilities Act" is 4–6 questions on the Unlimited exam (4–6 on the Residential exam as "Residential Life Safety and ADA"). The ADA half is the 2010 ADA Standards for Accessible Design. For an electrician the tested rules are about where controls go (reach ranges), how they operate (5 lbf, one hand), what counts as an obstruction in a route, and visible fire alarms. The numbers: 15 / 48 / 44 / 46 / 34 / 30 × 48 / 36 / 32 / 27 / 80 / 4 / 5 / 1:12 / 110 dB / 48–60.
1. Operable parts — 205 and 309
- 205.1: operable parts on accessible elements, accessible routes and in accessible rooms and spaces must comply with 309. The advisory lists exactly what that means for us: light switches, circuit breakers, duplex and other convenience receptacles, environmental and appliance controls, plumbing controls, security and intercom systems.
- Exceptions (205.1): parts used only by service or maintenance personnel; electrical or communication receptacles serving a dedicated use; where two or more outlets sit above an uninterrupted kitchen counter, one outlet; floor electrical receptacles; HVAC diffusers; and, except for light switches, where redundant controls serve one element, one control per space may be non-compliant. (Every light switch must comply.)
- 309: a clear floor space (305) in front of the control; the part within a 308 reach range; operable with one hand, without tight grasping, pinching or twisting of the wrist; activating force 5 pounds (22.2 N) maximum.
