WECT reported C.F. Pope Elementary in Pender County, North Carolina closing several kindergarten and preschool rooms after mould-like growth appeared during an HVAC shutdown; carpets were removed, rooms hand-cleaned and air quality tested. What should Thai schools prepare?
WECT reported on 17 August 2026 that mould-like growth appeared in several kindergarten and preschool rooms while the HVAC system was temporarily off for upgrades.
Measures were removing and cleaning carpets, hand-cleaning rooms, third-party air quality testing and keeping rooms closed until results cleared; the rest of campus was fine.
Thai kindergarten rooms often have carpets or foam mats for floor play and stay shut through long holidays. Hot, humid air speeds mould growth. Ventilating, inspecting rooms before term, removing damp materials, fixing moisture sources and cleaning surfaces with suitable products protect young children.

If buying equipment is not practical or the area is too large, use the World Health Disinfection disinfection service or ozone treatment service. The team wears full protective equipment, chooses products to suit the germ and surface, and reports after the job.
Q: Is spraying mould enough? A: No. Fix the moisture source, remove porous materials, then clean and test air quality before using the room.
Q: How long before the area can be used? A: After ULV fogging, areas are typically usable about 30 minutes later. For ozone treatment, no people or pets may be inside and the room must be ventilated before use.
Q: Can I get a tax invoice? A: Yes. Tax invoices are issued and 3% withholding tax is supported. Call 065-556-6294 or LINE @whd268.
Follow disease updates from Thailand's Department of Disease Control (hotline 1422) and the World Health Organization. Disinfection reduces germs in the environment and is not medical treatment; anyone with symptoms should see a doctor.
