Mould is perhaps the most well-known threat to indoor air quality.
But the Environmental Health Division is warning that other factors can also have negative effects, including poor ventilation, lack of fresh air, exhaust, inadequate housekeeping, and external contaminants.
“That is why it is imperative that we intensify our efforts to analyse and assess buildings, not just from an engineering and availability standpoint,” said Chief Environmental Health Officer Lionel Michael.
He also advised residents to consider architecture, spatial features, functionality and airflow before occupying a building.
The EHD, he said, started assessing buildings for air quality issues more intensely in the year following hurricanes Irma and Maria in 2017.
Data revealed that the main problems associated with poor indoor air quality in the territory include high concentrations of carbon dioxide and moisture; high air temperatures combined with inadequate ventilation; and uncomfortable office settings, Mr. Michael said.
Assessments
He added that the building assessments typically include reviewing carbon monoxide, carbon dioxide, temperature, humidity levels, housekeeping, building layouts, general sanitation and water intrusion.
Other indoor sources of air pollutants can include furnishings, cleaning products, and maintenance and personal care products, he said. Outdoor sources include vehicle exhaust, sewage, and dust from the Sahara Desert.
“If you can see mould in a building, that means that moisture is coming in from somewhere, because mould cannot grow without moisture,” he added. “There may also be mould coming inside from sources outside, such as trees, galvanise, garbage and other products that can blow the mould inside.”
Anyone concerned about indoor air quality issues may contact the EHD for advice at 468-5110.
