+ Note that handrails or guards used for exit stairs and exit ramps (as well as landings) must not be less than 107 cm*, unless the exterior stairs or landing is more than 10 m above the adjacent ground level, where by the guard must be not less than 150 cm*. Within a staircase, treads shall have a uniform run and tread depth that does not vary more than 0.5 to 1 cm*. What factors must we consider in designing safer stairs?Ī - Optimal range: 30º-35º B - Handrail height: between 86.5 and 107 cm* + C - Riser height: between 12.5 and 18 cm* D - Step width: 90 cm min.* E - Tread run: between 25.5 and 35.5 cm* The best approach to minimize the hazard of falling down stairs is to encourage the building of well-designed stairways, combined with training focused on raising our awareness of the potential for disaster. The fact is that some incidents can be caused by inattention, unsafe behaviour, and inappropriate footwear. The need for proper design also applies to ramps. Good design can substantially reduce the potential for mis-stepping by providing us with the means to retrieve our balance, but even the best design cannot eliminate falling hazards entirely. Please see our OSH Answers document on Prevention of Slips, Trips and Falls.Ī very common contributing factor is neglecting to use handrails.īecause stairway accidents can cause severe injury and even death, building codes for stairs and ramps are justifiably very rigorous. The vast majority of stairway falls result from a loss of balance, just as falls are on the level. Stairs of all types have been used since ancient times, and because they are inherently hazardous, people have been falling on them, getting hurt or even killed in the process.
