Tripping hazards have the same definitions on the exterior, interior, and dwelling units. Tripping hazards are defined as abrupt changes in vertical elevation or horizontal separation on any walking surface along the normal path of travel. There must be a difference of 3/4” in the walking path for vertical tripping hazards, and for horizontal hazards, the hazard must show at least two inches of separation. If the walking area has an engineer-designed gap or vertical difference, this is not a tripping hazard (e.g., a raised manhole or a plant grate designed in the middle of a path of travel).
|Tripping hazard – 3/4” vertical difference
|Tripping hazard – 2” horizontal separation
