Severe weather and window safety
Clear balcony drains before heavy rain
In safe weather, remove leaves, bags, and surface debris around balcony drain openings so water can flow.
Last reviewed: 2026-09-12
Why it matters
A blocked drain can cause water to build up, enter the home, create slips, and move loose objects.
Wrong action
Waiting until heavy rain or strong wind, then going onto the balcony to clear the drain by hand.
Correct action
Clear surface debris early; report slow drainage or damage to the employer and building management.
What to do
- Check the forecast and inspect the balcony before bad weather.
- Wear gloves and use a tool to remove surface debris around the drain.
- If flow stays slow or damage is seen, stop and report it.
If something happens
Do not enter the balcony to clear drains during heavy rain or strong wind. If flooding nears electricity or creates immediate danger, keep away and follow building or emergency instructions.
