The Michigan Occupation Safety and Health Act and OSHA Requirements for Stairways
According to the State of Michigan website, MIOSHA (Michigan Occupational Safety and Health Act) states that “A tread shall have a slip resistant surface and the stairs should have a vertical clearance of not less than 7 feet from any tread nose to an overhead object.” OSHA states that “All treads shall be reasonably slip resistant and the nosing shall be of a nonslip finish. Vertical clearance above any stair tread to an overhead obstruction shall be at least 7 feet measured from the leading edge of the tread.” It appears that both MIOSHA and OSHA agree on dimensions, which is vital in the construction of stairs, but they also agree on another important component: slip resistance.
