Testing and inspection of diving cylinders
Diving cylinders are like big metal tanks that hold compressed air for people to breathe while they go diving underwater. Because they're so important for keeping divers safe, they need to be carefully tested and inspected to make sure they're working properly.
First, the diving cylinder is checked to make sure it's not damaged on the outside. Then, the valve is checked to make sure it's not leaking air. Next, the cylinder is emptied of air, and a special machine is used to fill it up again to a certain pressure. This tests how much air the cylinder can hold without bursting.
After that, the cylinder is checked again to make sure it's not leaking air. Finally, a special device called a hydrostatic tester is used to test the cylinder's strength. This means the cylinder is filled with water and then pumped with even more pressure than it would experience during a dive. If the cylinder doesn't break, it's considered strong enough to be used for diving.
All of these tests and inspections are really important to make sure that divers are safe when they go underwater. So remember, checking diving cylinders is like checking a really important toy to make sure it's safe to play with.
