(2) Make sure that stairs with four or more risers have:
• Railings on the open sides of all exposed stairways and
stair platforms
• Handrails on at least one side of closed stairways,
preferably on the right side while descending
(3) Provide a platform where doors or gates open directly on
a stairway. The swing of the door must not reduce the effective
width of the platform to less than 20 inches.
Note:
To see all of the rules for building fixed stairs, refer to WAC 296-24-75011 and 296-24-765 of the General safety and health
standard.
