Equipment and safety equipment
The equipment is all of the fixtures mounted on the intended pressure vessel and purpose.
A safety device is an apparatus which can be used when the pressure within the vessel exceeds the required maximum.
The name plate is the complete identity associated with the vessel and is affixed to the vessel wall.
Pressurized Gas
Grouping of pressurized gases by their nature:
A gas that can reduce the acid level is a gas that can react chemically with other fuels.
Flammable gases are gases that readily react with oxygen and cause a fire.

Design / Planning
In this process, it is necessary to know in advance the pressure required to account for the thickness of the vessel including the thickness due to corrosion, as well as the temperature temperature required to maintain on the vessel wall as long as the vessel is operationalized.
The selection of construction materials is primarily intended for safety purposes as well as obtaining a low cost regardless of chemical influences.
Pressure vessels are distinguished by the shape of the body (stell), or the shape of the front (cap) or head. While the position is distinguished by axis or central line.
Source of Hazards and Effects that Pressure Vessels Can Inflict
Fire. Flammable gases packed in pressure vessels, when mixed with air and heat sources may cause a fire or explosion
Poisoning and irritation. Certain types of gases have toxic properties that are very harmful to humans and other living things because they can poison the blood in the body through the respiratory system and other body tissues.
Respiratory choking (Aspisia). A certain amount of gas that seems harmless because it is non-toxic and non-combustible. but can result in death if the gas has filled the enclosed space so that oxygen in the room is not enough to meet the needs of breathing.
Blasting. All types of pressurized gas stored in steel bottles and gas tanks have the danger of explosion due to the inability of the packaging to withstand the pressure of the gas present therein.

Exposed to very cold fluid (Crygenic). When exposed to a very cold liquid, the liquid immediately absorbs the body heat affected so as to cause injuries such as burns and damage to body tissue, and severe injuries can cause death if not get help immediately.
