What type of hazard is a gas cylinder?

What type of hazard is a gas cylinder?

Compressed gases expose users to both chemical and physical hazards. Gases contained within cylinders can be toxic, flammable, oxidizing, corrosive, inert, or a combination of these hazards.

Which of the following are hazards associated with compressed gas cylinders?

Hazards associated with compressed gases include oxygen displacement, fires, explosions, and toxic gas exposures, as well as the physical hazards associated with high pressure systems. Special storage, use, and handling precautions are necessary in order to control these hazards.

What are the hazards of gas under pressure?

Gases under pressure can release large amounts of gas into the workplace air very quickly which could result in health and/or fire hazards depending on the properties of the gas. The gas can be released deliberately by opening the cylinder valve, or accidentally from a broken or leaking valve.

How are gas cylinders identified?

Gas cylinders have internationally recognised markings and colours on the body and shoulders of the cylinder, also written labels or collars on the neck. In future the colour will only be on the shoulder of the cylinder – this will the recognised visual way to identify a cylinder hazard. COLOUR indicates the hazard.

What are the hazards in handling gas cylinders?

Compressed gas cylinders contain varying pressures of inert, toxic, flammable, oxidizing, corrosive, or combinations of gases. Care in using, handling, and storing compressed gas cylinders is required due to the high potential for severe incident.

What are the common gas hazards?


  • Asphyxiation: Simple asphyxiation is the primary hazard associated with inert gases.
  • Fire and Explosion: Fire and explosion are the primary hazards associated with flammable gases, oxygen, and other oxidizing gases.

What are several potential hazards of working with high pressure oxygen cylinders?

Pure oxygen, at high pressure – such as from a cylinder – can react violently with common materials, such as oil and grease. Other materials may catch fire spontaneously. Nearly all materials, including textiles, rubber and even metals, will burn vigorously in oxygen.

How do you handle high pressure gases?

Always use cylinders in cool well-ventilated areas. Handle “empty” cylinders safely: leave a slight positive pressure in them, close cylinder valves, disassemble equipment properly, replace cylinder valve protection caps, mark cylinders “empty” or “MT,” and store them separately from full cylinders.

What are the hazards of flammable gas?

Flammable gases can be heavier than air and may travel a considerable distance to an ignition source. Rapid flame propagation and flashback is possible. Cylinders containing flammable gases may vent rapidly or rupture violently as a result of pressure build-up, when involved in a fire situation.

When using high pressure cylinders What should you never do?

Ensure that the storage temperature does not exceed 52°C (125°F). Store, handle and use compressed gas cylinders securely fastened in place in the upright position. Never roll, drag, or drop cylinders or permit them to strike each other. Move cylinders in handcarts or other devices designed for moving cylinders.

What does hazard identification include?

Hazard identification process involves identifying both existing and potential workplace hazards, assessing the risks, determining and implementing the controls, and reviewing hazards.

What are the hazards of compressed gas cylinders?

There are two primary types of hazards associated with the use, storage and handling of compressed gas cylinders: The chemical hazard associated with the cylinder contents (corrosive, toxic, flammable, etc) The physical hazard represented by the presence of a heavy, high pressure vessel (explosion, fire, falling cylinder, etc)

What can cause a gas cylinder to explode?

Also, a sudden release of high pressure gas from a ruptured cylinder or from one with its valve accidentally broken off, can propel the cylinder in an uncontrolled manner. Except for oxygen, all gases are asphyxiants.

What are the OSHA compressed gas cylinder storage requirements?

OSHA compressed gas cylinder storage requirements should be followed on your site. A tank’s exposure to heat can render cracks and other weaknesses in the gas cylinders’ shells. This could obviously lead to a deadly explosion. Here are the compressed gas cylinder storage tips: Keep the tanks away from the sun, flames, sparks,

What hazard class does the gas cylinder pictogram belong to?

This pictogram is used by one hazard class in the physical hazards group – Gases under pressure. There are four hazard categories in this hazard class: dissolved gas. What are the hazards of products that have the gas cylinder pictogram?
