When cylinders are transported by powered vehicles, they shall be secured in a vertical position. Valve protection caps shall not be used for lifting cylinders from one vertical position to another. Cylinders should be stored in definitely assigned places away from elevators, stairs, or gangways.
What is the minimum distance that is required for the separation of oxygen cylinders from fuel gas cylinders?
(g) Oxygen cylinders in storage shall be separated from fuel-gas cylinders or combustible materials (especially oil or grease), a minimum distance of 20 feet or by a noncombustible barrier at least 5 feet high having a fire-resistance rating of at least one-half hour.
What do moving cylinders always remove?
When moving the cylinders, always remove the regulator and install the valve cap. Cylinders should be kept in a vertical position and chained to a permanent structure during use and storage. An oxygen cylinder at 2,000 psi can become a lethal projectile if it falls over and the cylinder valve is damaged.
When oxygen and fuel gas cylinders are in storage What safety feature should be securely in place on top of the cylinder?
Valve-protection caps, where cylinder is designed to accept a cap, shall always be in place. Cylinders shall not be dropped or struck or permitted to strike each other violently. Valve-protection caps shall not be used for lifting cylinders from one vertical position to another.
When in use fuel gas cylinders should be placed with the valve end up?
1926.350(b)(3) Fuel gas cylinders shall be placed with valve end up whenever they are in use. They shall not be placed in a location where they would be subject to open flame, hot metal, or other sources of artificial heat.
What will you do when cylinders are not in use?
Close all valves when cylinders are not in use. Never tamper with safety devices in cylinders, valves or equipment. Do not allow flames to contact cylinders and do not strike an electric arc on cylinders. Always use cylinders in cool well-ventilated areas.
What happens when a gas cylinder falls over?
A sudden release of these gases can cause a cylinder to become a missile-like projectile. Physical Damage: Cylinders are very hazardous when exposed to damage from falling over, tipping, heat, electric circuits, motion, vibration, or anything that can cause a weakness or crack in the cylinder wall or shell.
When cylinders are transported by powered vehicles they must be secured in a position?
When cylinders are transported by powered vehicles, they shall be secured in a vertical position. Valve protection caps shall not be used for lifting cylinders from one vertical position to another.
What is the rule of storing gas cylinders?
Cylinders should be stored preferably in the open air on a concrete or load-bearing surface. Flammable liquids, combustible, corrosive, oxidising materials, toxic materials or compressed gas cylinders should be kept separate from LPG containers in general. Containers should be stored with their valves uppermost.
What distance should oxygen and acetylene cylinders be stored?
Class 2.1 flammable gases (acetylene) and Class 2.2 non-flammable oxidising gases (oxygen) must be stored at least 3 metres apart (more information on the classification of gases can be found here).
How are compressed gas cylinders disposed of when they are empty?
Once a cylinder is empty and is to be discarded, it should be recycled. Scrap metal recycling companies sometimes have restrictions on the types of cylinders that they will take, or require that they be cut in half or for the cylinder valve be removed to prove that they are empty.
Can gas cylinders be transported lying down?
Compressed gas cylinders shall be secured in an upright position at all times except, if necessary, for short periods of time while cylinders are actually being hoisted or carried. The standard applies to all compressed gas cylinders, regardless of whether they are filled, partially filled, or empty.
How is gas compressed in a cylinder?
Liquefied Gases Initially the cylinder is almost full of liquid, and gas fills the space above the liquid. As gas is removed from the cylinder, enough liquid evaporates to replace it, keeping the pressure in the cylinder constant.
Which two items are approved methods for keeping cylinders and fuel-gas cylinders separated when they are stored in the same storage area?
Which two items are approved methods for keeping cylinders and fuel-gas cylinders separated when they are stored in the same storage area? -A noncombustible partition with fire resistance rating of at least 30 minutes between the two types.
How are oxygen and acetylene cylinders transported?
Acetylene, LPG cylinders and liquefied gases must always be transported in an upright position. The load restraint equipment and the vehicle body and attachments must be strong enough for each type of load carried, and must be in good working condition.
When should you close the cylinder valve?
A cylinder in such a system should be shut off and removed from the system when the pressure remaining in the cylinder is at least 172 kPa (25 psi/in2). If there is a possibility that the container has been contaminated, it should be so labeled and returned to the supplier.
Why should a safety cap be used on a cylinder when it is moved or stored?
Why should a safety cap be used on a cylinder when it is moved or stored? A safety valve prevents an explosion when the cylinder is exposed to high temperatures. A safety disc inside the valve ruptures and slowly releases the oxygen in the cylinder.
Who is responsible to transport empty or not in use cylinders to materials management?
The user is solely responsible for the proper disposal of the cylinder when it is empty or no longer needed. 5. The user is responsible to maintain an inventory of all gases (cylinders) used and stored in their area.
When needed this must be left in position on the stem of the valve while?
When a special wrench is required, it shall be left in position on the stem of the valve while the cylinder is in use so that the fuel gas flow can be shut off quickly in case of an emergency.
