Why store acetylene cylinders upright

The top of the cylinder comprises brass valves, a metal cap, and often safety fuse plugs. Knowing the composition and traits of an acetylene cylinder will help a user understand and safely handle and store acetylene cylinders. There are specific instructions that users need to follow when storing acetylene cylinders.

These instructions are divided into three parts. These include gloves, goggles, cotton clothing, and fire extinguishers. Acetylene cylinders should always be stored upright, with the valve end in the upward position.

The cylinder valve should always be kept closed when not in use and the fuse plug s should be checked to verify a tight seal. The cylinders should never be stored in extreme temperature environments.

In freezing temperatures, the pressure may drop within the cylinder to nearly zero and when flowed, acetone may leak from the cylinder resulting in clogging of downstream equipment such as a regulator. Acetylene cylinders should be stored separately from cylinders containing other gases. The cylinders need to be protected from potential mechanical and physical damages. Cylinders that are stored indoors need to be placed in an area with the following guidelines:.

The storage area should have a fire resistance rating of 2h. This is the rating for flammable gases. The area should have the requisite amount of ventilation, however, it should also prevent gas migration within the building. Acetylene storage areas should meet Class 1, Division 1, Group A ratings with all equipment in the area meeting this classification. Follow Us on:.

Never crack hydrogen cylinders since the release of compressed hydrogen may ignite by itself.

Store cylinders in a clearly identified, dry, well-ventilated storage area that is not exposed to heat or the direct rays of the sun, and away from doorways, aisles, elevators, and stairs. Post "no smoking" signs in the area. Store cylinders, both empty and full, in the upright position and secure with an insulated chain or non-conductive belt.

During storage, close the cylinder valves with the protective caps in place. With outside storage, place on a fireproof surface and enclose in a tamper-proof enclosure. Protect cylinders from contact with ground, ice, snow, water, salt, corrosion, and high temperatures.

Protect cylinders from falling. Use a chain or adequate support system. Consider securing each cylinder separately to prevent other cylinders from falling when items are removed from storage. Store oxygen cylinders and fuel gas cylinders separately.
