5. Widen opening on loft stairs where necessary to meet NFPA compliance for stair width clearance and install OSHA-compliant handrails on loft and deck stairs.

The stairs leading to the A-frame cabin deck have eight risers. The stairs are equipped with a guardrail but no handrail. The stairs to the loft bedroom are 24 inches wide. The existing handrail begins at the third riser and extends to the fifth riser (right side ascending). The remaining risers are not equipped with a handrail.

Stairs must be 36 inches wide per NFPA 101, 7.2.2 - Stairs as outlined in the below table.

NFPA Existing Stairs Dimensions Table

A handrail is a rail used to provide employees with a handhold for support.

Handrails must be not less than 30 inches and not more than 38 inches, as measured from the leading edge of the stair tread to the top surface of the handrail. Handrails and stair rail systems must have smooth surfaces to protect employees from injury, such as punctures or lacerations, and to prevent catching or snagging of clothing. They must have the shape and dimension necessary so employees can grasp the handrail firmly. In addition, handrail and stair rail systems are required to have a minimum clearance between handrails and any other object is 2.25 inches. The ends of handrails and stair rail systems must not present any projection hazards.

Handrails and the top rails of stair rail systems must be capable of withstanding, without failure, a force of at least 200 pounds applied in any downward or outward direction within 2 inches of any point along the top edge of the rail.

A stair rail is a barrier erected along the exposed or open side of a stairway to prevent employees from falling to a lower level. OSHA requires each flight of stairs having at least three treads and at least four risers to be equipped with stair rail systems and handrails as outlined in the table below:

OSHA Handrail Table

A stair railing consists of a top rail, midrail, and posts, and must have a vertical height not more than 34 inches nor less than 30 inches from the upper surface of the top rail to the surface of the stairs. The length of the railing top rail must be smooth. The midrail must be located approximately halfway between the top rail and the stairs. Guardrail systems must be capable of withstanding, without failure, a force of at least 200 pounds applied in a downward or outward direction within 2 inches of the top edge, at any point along the top rail.

The height of stair rail systems installed before January 17, 2017, must be not less than 30 inches from the leading edge of the stair tread to the top surface of the top rail; the height of stair rail systems installed on or after January 17, 2017, must be not less than 42 inches from the leading edge of the stair tread to the top surface of the top rail.

For installations prior to January 17, 2017, the top rail of a stair rail system may serve as a handrail when the height of the stair rail system is not less than 36 inches and not more than 38 inches as measured at the leading edge of the stair tread to the top surface of the top rail.

For stair rail systems installed on or after January 17, 2017, the top rail and handrail must be separate. The top rail must be at least 42 inches high, and the handrail must be 30 to 38 inches high (as measured at the leading edge of the stair tread to the top surface of the rail).
