When carrying out work at great depths, professional divers stay in a diving bell for several days, breathing a mixture of gases containing a high proportion of helium. The pressure is gradually increased to reach the pressure at the working depth. Hack result exam uitm 2017. The divers, still inside the bell, are then lowered to the working site.

They leave the bell to carry out their work. Once their work is complete, they re-enter the bell, which is then raised to the surface. Pressure is then returned to atmospheric levels and this is when the valve must be opened (only for deep-sea dives lasting several days).
