Employers and institutions with fire extinguishers available to staff personnel are subject to Occupational Health and Safety Act (OSHA). One of those requirements is compliance with 29 CFR 1910.165(b).
In effect, the regulation requires the development and adherence to a Safety Plan that includes mass notification capability to ALL personnel in the event of an emergency. Fines for non-compliance typically range from $7,000 to $70,000. If you would like more information on simple and effective compliance solutions, just click here.
