After a typhoon, first assess structural damage and moisture in appliances; do not disassemble electrical circuits yourself. Prioritize clearing standing water to prevent mold, and wear appropriate protective gear. For wall mold, thoroughly fix leaks before cleaning, and strictly prohibit painting or sealing on damp surfaces.
Assessment and safety measures
Ensure the environment is safe before cleaning. If you find wall cracks, ceiling peeling, or exposed wiring, immediately pause DIY and contact professionals. When cleaning, wear non-slip shoes and gloves, ensure indoor electrical equipment is disconnected, and never operate appliances in slippery environments.
- Check structure and electrical safety
- Record the location of damage for assessment
- Wear protective gear to guard against sharp objects like broken glass
Cleaning up standing water and debris
Mud and sand brought in by the typhoon should first be cleared with a broom to avoid making the ground even dirtier with wet mopping. Use a wet vacuum or absorbent cloth to deal with standing water as soon as possible. If the water involves sewage, disinfect cleaning tools in diluted bleach after use.
Before using bleach, please first understand Method for using bleach from the Centre for Health Protection(opens in a new window), and operate according to the product label.
- Clear debris and trash
- Vacuum up standing water and dry the surface
- Disinfect tools used for sewage
Preventing mold regrowth
The damp environment after a typhoon is a breeding ground for mold. Once black spots or mold odors appear on surfaces, scrub them off as soon as possible and keep the environment thoroughly dry. Do not apply paint or sealant before removing mold, otherwise the mold will cause the coating to peel off.
When handling moldy materials, you can follow US Environmental Protection Agency's home mold prevention recommendations(opens in a new window)treatment and note the on-site and material restrictions.
- Check hidden spots for mold
- Thoroughly ventilate to remove moisture
- Repair the source of the leak
