Watch out: A throw rug or carpet at the top of a stairway is asking for a serious stair fall even if it does provide a color change. This review explores existing literature in the area of stair negotiation by older persons in an effort to define the key factors associated with difficulty and safety on stairs and to interpret these findings in the light of possible interventions that could increase stair safety. The stair tread depth shall be measured horizontally between the vertical planes of the foremost projection of adjacent treads and at right angle to the tread's leading edge. Also see EXTERIOR STAIR FALLS for a catalog of causes of falls on stairs that includes surface conditions and other defects. Place the Glowstrip in any location within the stair nosing. The slippery tile walking surfaces shown above and the very short step up - less than 3cm - is a near guarantee of stubbed toes. Click to Show or Hide Citations & References, OSHA estimates that there are 24,882 injuries and as many as 36 fatalities per year due to falls from stairways and ladders used in construction.

For wooden stair treads the tread thickness must be. Zamma Distressed Brown Hickory 3/4 in. I did some research on tripping and protruding nosings and found that the Australian code does not allow open risers or protruding lips/nosings on stair treads precisely because they are a trip hazard for the disabled. 27.4.2 Height: Top of handrail gripping surface sha ll be mounted between 34 inches (34" = 864m m) and 38 inches (38" = 965m m) above stair nosings. We offer stair nosing & landing tread in nearly two dozen species of hardwood, including oak stair nose, brazilian cherry stair nosing, and even tigerwood stair nosing. While a tread nose is not required on stairs with open risers, closed riser stairs like these should have a tread nose projection that is typically specified as follows: UBC 1009.3.2 Profile.
