These irritants may cause distress to the occupants of the
building in the form of physical symptoms such as watery eyes, coughing and
frequent dryness. Especially sensitive to these are the very young, the very
old, and those with asthma.
Proper maintenance of the
HVAC system includes the source cleaning of the ductwork with agitation and a
negative air HEPA unit designed to capture (not spread) these particles, and
certified as to ffectiveness. Special attention should be given to the heating
or cooling unit itself, including any re-heat coils found down the line. All
registers should be removed and cleaned. An OSHA approved, anti-microbial
sanitizing solution may be added to the cleansed system as a barrier to
prohibit further growth. |
