Under 1926.35(a), which workplaces must have an emergency action plan and does it have to be written?
Yes — any workplace that is required by a particular OSHA standard to have an emergency action plan must have one, and it must be in writing except for a small-employer exception. The rule states that 1926.35 applies to all emergency action plans required by a particular OSHA standard and that the plan shall be in writing except as provided in 1926.35(e)(3). See Scope and application in 1926.35(a) and the small-employer exception in 1926.35(e)(3).
