In occupancies of an especially hazardous nature, or where special hazards exist in addition to the normal hazard of the occupancy, or where access for fire apparatus is unduly difficult, additional safeguards may be required by the Director consisting of additional fire appliance units, more than one type of appliance, or special systems suitable for the protection of the hazard involved. Such devices or appliances may consist of automatic fire alarm systems, automatic sprinkler or water spray systems, standpipe and hose, fixed or portable fire extinguishers, suitable asbestos, blankets, breathing apparatus, manual or automatic covers, or carbon dioxide, foam or other special fire extinguishing systems. Where such systems are installed, they must be in accordance with the applicable standards of the National Fire Protection Association. (1975 L.M.C., ch. 23, § 1; 2016 L.M.C., ch. 30, §1.)
