What are the imperative safety instructions to follow?

– Never block your breathing whether it is going up or going down
– Never descend if you feel a sensation of discomfort in the ears, nose or eyes
– Never rise quickly (never faster than small air bubbles)
– Check your pressure gauge very regularly
– Never use the SMACO bottle on the surface when the needle of its pressure gauge is in the red zone.
It is also very important to explain these basic rules to anyone using the SMACO product.
