What kind of special protective wear do deep sea divers need?

What do sea divers need special protective suit?

Why do sea divers need a special protective suit? It is due to the great pressure exerted on the diver’s body at the depth of the sea. The total pressure exerted is much more than his blood pressure. Consequently, to withstand that sea divers require special protective suit.

What does a deep sea diver wear?

Standard diving dress consists of a diving helmet made from copper and brass or bronze, an air hose from a surface-supplied manually operated pump or low pressure breathing air compressor, a waterproofed canvas suit, a diving knife, and weights to counteract buoyancy, generally on the chest, back and shoes.

Why do divers need protective suits?

The sea divers need special protective suit to wear because in deep sea, the total pressure exerted on the diver’s body is much more than his blood pressure. To withstand it, he needs to wear a special protective suit.

What suits do divers wear?

Some divers prefer to wear a jumpsuit (or one-piece full suit), while others prefer to wear a shorty suit that covers only the diver’s torso. Still others will wear a jacket and others still will wear a jacket with a separate “farmer john” or “farmer jane” covering the diver’s torso and legs.

What is the deepest diving suit?

An atmospheric diving suit allows very deep dives of up to 2,000 feet (610 m). These suits are capable of withstanding the pressure at great depth permitting the diver to remain at normal atmospheric pressure.

Depth ranges in underwater diving.

Depth Comments
332 metres (1,089 ft) World record for deepest dive on SCUBA.

Why do the bodies of deep sea fish burst when they are brought to the surface of sea?

To avoid being crushed by the water pressure, fish have an internal body pressure that is equal to that of the external water pressure. When the fish are raised to the surface rapidly, their internal pressure then is much greater than the air pressure, and it can cause their bodies to burst.

How does the liquid pressure on a diver change if?

The pressure of water increases with depth. So when a diver moves to greater depth, the volume of water above him increases and it proportionally increases the pressure exerted by the water on the diver. So pressure increases as diver moves to greater depths in the water.
