Buildings should be designed to allow effective cleaning and thorough application of disinfectants to all internal surfaces. Some buildings will contain complex piping, machinery and tank systems that may be difficult to disinfect. Wherever possible, buildings should be cleared of debris and emptied of equipment, prior to disinfection.
Misting or foaming agents are options for disinfection of complex areas and vertical surfaces. Fumigation can be considered for large or difficult to access areas if buildings can be adequately sealed.
