Air Duct cleaning after a Fire: Air ducts supply necessary air circulation and ventilation. But when ducts are saturated with dust, soot, smoke odour, mildew, and other airborne contaminants, they can become a dangerous conduit, spreading contaminated fine particles into the occupied spaces i.e. furniture, fixtures and, most importantly, to the individuals working or living in the structure.
Duct Cleaning - Preventive maintenance: Air duct collects dust and debris over time. Contaminants in an air duct range from dust and soil, to dead insects and rodents, bacteria, fungi and mould. The air duct is a perfect breeding ground for biological contaminants due to enclosed space, with temperature, humidity and dirt as a nutrient source.
Most of us stay in an indoor environment most of our working life. Pollutants inside the air duct get circulated in the ventilation air and pollute the indoor air. Indoor air pollution may cause allergic and asthmatic reactions among building occupants as well as lead to other health problems.
From the economic point of view, the improved air quality can reduce worker absenteeism and increase productivity.
Air duct cleaning involves four processes: inspection, laboratory testing, mechanical cleaning and application of antimicrobial. A robotic inspection system is to visually inspect the air duct before and after the cleaning. Tests are conducted in laboratories to evaluate the hygiene levels before and after the air duct cleaning. A mechanical cleaning method is employed to remove particulate, debris and surface contaminants. Finally the entire ductwork is disinfected using anti-microbial treatment.
