If the wind is in excess of 45Km/h, do not perform any movements liable to endanger the lifting platform’s stability.
- To recognise this speed by eye, please refer to the empirical wind evaluation scale below:

Ground effects Sea conditions
0 Calm 0 - 1 0 - 1 < 0,3 Smoke rises vertically. The sea is like a mirror.
1
Very light
breeze
1 - 3 1 - 5 0,3 - 1,5
The smoke drift indicates the wind
direction. Some wavelets, like fish scales, but no
foam.
2 Light breeze 4 - 6 6 - 11 1,6 - 3,3
Wind felt on exposed skin, leaves
rustle. Small but noticeable wavelets.
3
Gentle
breeze
7 - 10 12 - 19 3,4 - 5,4
Leaves and small twigs constantly
moving. Very small waves, crests beginning to
break.
4
Moderate
breeze
11 - 16 20 - 28 5,5 - 7,9
The wind raises dust and scraps of
paper, it moves small branches. Small waves stretching, many sheeps.
5 Fresh breeze 17 - 21 29 - 38 8 - 10,7
Small trees in leaf start to sway. Wavelets form on stretches of water,
moderate waves of some length.
6
Strong
breeze
22 - 27 39 - 49 10,8 - 13,8
Large branches are moved, overhead
wires whistle, umbrella use becomes
difficult. Waves form with white foam crests
and airborne spray.
7 High wind 28 - 33 50 - 61 13,9 - 17,1
Whole trees are moving, effort
required to walk against the wind.
The sea heaps up; some foam from
breaking waves is blown into streaks
in the wind direction.
8 Gale 34 - 40 62 - 74 17,2 - 20,7
The wind breaks off twigs, walking
against the wind is very difficult. Moderate height longer waves with
breaking crests forming spindrift.
9 Strong gale 41 - 47 75 - 88 20,8 - 24,4
The wind damages roofs (chimneys,
tiles, etc.). Large waves, dense spindrift
wrenched from the waves, airborne
spray reducing visibility.
10 Storm 48 - 55 89 - 102 24,5 - 28,4
Rarely seen on land, trees uprooted,
dwellings incur significant damage. Very large waves, foam forming large
amounts of airborne spray, reducing
visibility.
11 Violent storm 56 - 63 103 - 117 28,5 - 32,6
Very rare, extensive damage. Waves of exceptional height capable
of sinking medium-sized ships,
reduced visibility.
12 Hurricane 64 + 118 + 32,7 +
Disastrous damage. Sea completely white, air full of spray
and foam, severely reduced visibility.
