How often must employers review and update their written emergency action plan?

Employers are required to review and update their written emergency action plan at least annually to ensure that it reflects current workplace conditions and remains effective in case of an emergency. This annual review is crucial because it allows employers to identify any changes in the workplace, such as new equipment, processes, or personnel, that could impact emergency procedures. Additionally, reviewing the plan annually allows for the incorporation of lessons learned from any emergencies that may have occurred within the past year. While ongoing training and updates may be necessary when significant changes occur or new employees are hired, an annual review ensures that the plan is regularly evaluated and improved as needed, aligning with best practices in workplace safety.
