HURRICANES AND CYCLONES
SAFETY TIPS FOR VOLUNTEERS & PERSONNEL WORKING IN DISASTER-AFFECTED AREAS
Hurricanes, typhoons, and cyclones are essentially the same weather phenomenon, but they are given different names based on their location in the world
They are large swirling storms with winds speeds that can exceed 100 kilometres an hour. They form over warm ocean waters and sometimes strike land with a destructive force that can damage buildings and trees.
When they reach land, they push a wall of ocean water ashore; this is called a “storm surge.” Heavy rain and storm surges can cause severe flooding.
You’ll likely have several hours to several days of warning before these storms make landfall.
You should know that…
A hurricane or cyclone will worsen any existing flooding and may create different flood patterns. You and your team should not be outdoors when the cyclone hits, and should instead seek shelter in safe, solid housing. Storm surges and cyclones in areas that have already been flooded can undermine building foundations by constant agitation of the water – already at a high level from the flood – while the force of the cyclone does the rest. This can result in a building being completely demolished. It is therefore extremely important to stay in houses that are strong and that have not already been affected by flooding. Also, bear in mind that additional flooding and cyclones can easily trigger mudslides and landslides
Before
Make a plan, rehearse it and make an emergency kit.
Before the storm hits, you and your team should regroup in a pre-planned, safe location on high ground and inside a stable structure.
The property (residence) and surroundings should be free of any loose material that could cause injury and damage during extreme winds. Your location and that of your team members should be battened down, i.e., secure the doors, and board up and tape or cover the windows to avoid flying glass and other objects from coming in.
Have your emergency kit ready.
During
Remain indoors – away from windows, skylights, and glass doors – and remain in the strongest part of the building.
In flood-prone areas, do not use the cellar or basements since these areas can be extremely dangerous due to existing flooding.
If the building you are in starts to break up or fall apart, then the only option is to protect yourself with a mattress, rugs, blankets, or tarpaulin, and to hold onto any strong fixtures (such as water pipes), or get under a strong, heavy table or bed. Do not run out into the open.
Beware of the calm when the eye of the storm is over your area, and do not assume the cyclone is over (the blowing of violent and strong winds will soon resume).
If you are driving, stop and stay clear of trees, power lines, and streams. Avoid using naked flames, such as candles and paraffin lamps, as a source of light. Take cover in a room without windows.
After
Be careful to avoid damaged power lines, bridges, buildings, trees, and any floodwaters.
Undertake a head count to make sure all the team members are safe and sound.
