The vest is simply called a scuba vest. It's to hold your air tank and regulators :)

Is it safe to get in a tub and turn the water on if you are trapped in a fire?
No. The gasses and lack of oxygen will kill you unless you wear your scuba gear too.
How do scuba divers alter their average density to float?
Divers usually increase their density by wearing a weight belt (which contains lead weights). Some divers also rely, to a lesser degree, on using steel tanks, which are more dense than aluminum tanks. To decrease their density, divers put air into a Bouyancy Control Device (BCD). Some divers may also control bouyancy by putting air into a drysuit if they wear one. Whereas the increase in density created by the weightbelt is normally fixed, the positive bouyancy provided by the BCD can be varied throughout the dive. Usually a divers net density will decrease over the dive - a diver with a full scuba tank has about 4.5 lbs of extra weight (the weight of the gas) over a diver with an empty scuba tank.
Do the diver has to wear arm-bands?
no
Why do scuba divers wear heavy metallic suits?
Scuba divers do not wear heavy metal suits. Perhaps you are referring to the bulky looking Mark 5 dive gear with the large helmet and the breast plate that weighs 64 pounds. Suit weighs 25 lbs. Each shoe weighs 25 lbs. Oh, the weight belt the diver wears is 60 to 80 lbs. All this weight is needed to get the diver to sink from all the air inside the helmet.
What helps a diver breath?
Divers wear tanks full of oxygen to help them breathe while they are under water. When the tanks start to get empty, they resurface.
Why are most scuba diving helments brown?
SCUBA means self contained breathing apparatus. Most scuba divers wear neoprene hoods and these come in a variety of colours. I think you are talking about standard dress or hard hat diving where the diver has a big spherical helmet and lead boots. These divers are not SCUBA as they have air pumped from the surface. These helmets look brown because they are made of brass and copper which turns brown when it oxidises. If you polished it up, it would look gold in colour.
What kind of cloths does divers wear?
Diver Suits
What does a marine bioloigist wear?
scuba diving equiment
