FLOODS
SAFETY TIPS FOR VOLUNTEERS & PERSONNEL WORKING IN FLOOD-AFFECTED AREAS
During a flood: "turn around, don't drown"—never try to walk, swim or drive through swift water.
Floods are when water overflows from the normal boundaries of a stream, river or other body of water, or accumulates in an area that is usually dry. There are two main types of floods. Inundation floods are slow and develop over hours or days. Flash floods occur suddenly, often without warning and usually due to heavy rain.
Floods are one of the most common disasters and more dangerous than most people think. Just a few centimetres of flooding can be extremely erosive and destructive.
You should know that…
Flash floods are especially dangerous. They can happen with little or no warning and usually result from intense rainfall over a relatively short period.
Walking in flood waters is dangerous as many dangerous objects and hazards may be hiding below the surface (such as sharp and electrified objects and holes you can fall into).
Beware of electrical hazards and stay clear of downed power lines. Be aware that water can become electrically charged.
Be aware that roads, bridges, and buildings can quickly become weak and unsafe. Stay out of buildings if floodwater remains around the building.
Be aware that water is often heavily contaminated by chemicals and sewage. Don’t drink it or bathe in it.
It takes only 15 cm (ankle height) of fast-moving water to knock you off your feet.
It takes only 60 cm to cause most cars to float
Remember that the danger may still be present even after the water recedes (snakes, power lines, hazardous materials, etc).
When on foot…
If you come upon a flooded area - Don’t drown: turn around.
If you see or suspect the water is rising, get to higher ground and inform your supervisor immediately.
Avoid walking through floodwaters, especially if it is moving swiftly as it can easily sweep you off your feet.
Climb to high ground. Avoid walking through floodwater, especially if it’s moving swiftly.
When driving…
If you come upon flooded areas - Don’t drown: turn around.
If the vehicle starts to lose grip and begins to float, open the doors to let in water to weigh it down.
If your car stalls, abandon it immediately and climb to higher ground (many deaths have resulted from people attempting to move stalled vehicles).
Drive with the windows open (for quick escape if needed).
Drive only fast enough to create a small bow wave in front of the vehicle, which will prevent the engine from getting wet and the tires from losing their grip.
Follow recommended evacuation routes, as shortcuts may be blocked.
