Retro-reflective materials should be fitted around the canopy
of the liferaft. The material should be sufficiently wide and long
to give a minimum area of 150 cm2 and should be spaced
at suitable intervals (approximately 80 cm from centre to centre)
at a suitable height above the waterline, doorways included, if suitable.
On inflatable liferafts, retro-reflective materials should also be
fitted to the underside of the floor, cross-shaped in the centre.
The dimension of the cross should be half the diameter of the liferaft,
and a similar cross should be applied to the top of the canopy.
On liferafts which are not equipped with canopies, materials
which should be sufficiently wide and long (to give a minimum area
of 150 cm2) should be attached to the buoyancy chamber
at suitable intervals (approximately 80 cm from centre to centre)
in such a manner that they are visible both from the air and from
a ship.
