LAC 51:XX.105. Heating, Cooling, and Ventilating Systems [formerly paragraph 20:003]

A. [Formerly paragraph 20:003] All homes shall be provided with heating equipment adequate to maintain, in every room used by patients, a temperature of not less than 76 degrees Fahrenheit in the coldest weather. Each room having a bathtub, or shower, or toilet shall have a heater, or a duct to it from a heating system. The combustion chambers of all heating systems, and other fired equipment shall be vented to the atmosphere. Other parts of the heating, cooling, and ventilating system shall be so designed, built, and maintained as to ensure that the pressure in the space from which combustion air is drawn does not become negative with respect to the atmosphere. B.1. [Formerly paragraph 20:003-1] Persons with tuberculosis in a communicable state or suspected of having tuberculosis in a communicable state shall be cared for in isolation rooms with negative air pressure and either: a. at least six changes of room air per hour accomplished by exhaust ventilation; or b. equivalent circulation and treatment by ultraviolet light treatment, "air scrubber", or equivalent. 2. If the patient is not in a room with proper ventilation and is unable or unwilling to cover their cough, then exposed persons shall wear proper masks, which filter all particles larger than 1 micron, in order to prevent the spread of infectious respiratory droplets.
