Compressed gases can be toxic, flammable, oxidizing, corrosive, inert, or some combination of these hazards. In addition to the chemical hazards, the amount of energy resulting from the compression of the gas makes a compressed gas cylinder a potential rocket.
Does compressed gas in cylinder present a health hazard?
Compressed gases can cause fires, explosions, oxygen deficient atmospheres, toxic gas exposures as well as the innate physical hazard associated with cylinders under high pressure.
What hazards do compressed gas cylinders pose?
What are the hazards of products that have the gas cylinder pictogram? Contains gas under pressure; may explode if heated. Contains gas under pressure; may explode if heated. Contains refrigerated gas; may cause cryogenic burns or injury.
What type of hazard is a gas cylinder?
Improper handling of cylinders could result in sprains, strains, falls, bruises, and broken bones. Other hazards such as fire, explosion, chemical burns, poisoning, and cold burns could occur if gases accidentally escape from the cylinder due to mishandling.
What is a compressed gas cylinder?
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.
Why are gas cylinders hazardous?
Gases contained within cylinders can be toxic, flammable, oxidizing, corrosive, inert, or a combination of these hazards. Because the pressurized chemical is released in gaseous form, a leak from the cylinder, regulator, or any part of the system used to deliver the gas can quickly contaminate a large area.
What are compression hazards?
Compression (pinching/crushing/roll-over)—Examples: Working with or around moving equipment, or parts. Exposure to falling objects. Use of heavy equipment or tools that could cause compression injuries, etc. Thermal (Hot/Cold)—Examples: Operating furnaces, pouring and casting hot metal, welding.
When storing a compressed gas cylinder where must it be placed?
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, gangways, and stairs.
What are the safety measures for handling of compressed gas cylinders?
Secure cylinders upright with a chain or strap in a proper cylinder cart. Store cylinders at least 20 feet from combustible materials in a dry, ventilated place. Keep oxygen cylinders at least 20 feet from fuel gas cylinders. Ensure valves are completely closed and any protection devices are secured.
What is the major hazard when a gas compressed inside a cylinder is exposed to high temperatures?
What is the MAJOR hazard when a gas compressed inside a cylinder is exposed to high temperatures? The gas inside the cylinder will cause the pressure to increase. The safety valve of the compressed cylinder will be activated.
Are all compressed gases flammable?
Compressed gases can be toxic, flammable, oxidizing, corrosive or inert. In the event of a leak, inert gases can quickly displace air in a large area creating an oxygen-deficient atmosphere, while toxic gases can create poison atmospheres, and flammable or reactive gases can result in fire and exploding cylinders.
What is the primary hazard associated with flammable gases?
Fire and Explosion: Fire and explosion are the primary hazards associated with flammable gases, oxygen and other oxidizing gases. Flammable gases can be ignited by static electricity or by a heat source, such as a flame or a hot object.
What are examples of compressed gas?
Common compressed gases are: propane, nitrogen, chlorine, helium, and oxygen.
What happens if a gas cylinder falls?
A broken valve resulting from a falling cylinder is all it takes for the cylinder to become an unguided missile. Any uncontrolled release of gas under pressure can create a dangerous environment. Once the cylinder cap is removed, always inspect the valve for odors, visible plumes or hissing sounds.
Can compressed gas cylinders be stored inside?
(11) Inside of buildings, cylinders shall be stored in a well-protected, well-ventilated, dry location, at least 20 feet (6.1 m) from highly combustible materials such as oil or excelsior. Cylinders should be stored in definitely assigned places away from elevators, stairs, or gangways.
What are five basic rules for using compressed gas cylinders?
- Store cylinders properly.
- Keep cylinders secured.
- Inspect cylinders before moving or using.
- Open them carefully.
- Follow procedures for empty cylinders.
How do you identify a compressed gas cylinder?
Identification. The contents of any compressed gas cylinder must be clearly identified. Such identification should be stenciled or stamped on the cylinder or a label. Commercially available three-part tag systems may also be used for identification and inventory.
What are compressed gas cylinders made of?
Gas cylinders can be made from aluminum, steel, alloys, and composite materials. Mechanical strength, corrosion resistance, and impact resistance are critical factors in determining which material is used.
What are the general safety requirements of compressed gas?
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 is a hazardous gas?
Hazardous gases are those gases that are sufficiently toxic and/or reactive to meet one of the definitions given below. They include acutely toxic, corrosive, flammable, dangerously reactive and oxidizing gases.
What type of hazard is compressed air?
What are the hazards of using compressed air? First, compressed air is extremely forceful. Depending on its pressure, compressed air can dislodge particles. These particles are a danger since they can enter your eyes or abrade the skin.
When inspecting a compressed gas cylinder you should?
29 CFR 1910.101(a) states employers must visually inspect compressed gas cylinders to ensure that they are in a “safe condition.” Visual cylinder inspections should look for leaks, bulging, defective valves, evidence of physical abuse, fire or heat damage, pitting, rusting or corrosion.
Which compressed gas has a primary hazard of asphyxiation?
Argon and carbon dioxide are asphyxiants. Asphyxiants (including inert gases) can displace oxygen and may cause suffocation. Atmosphere-supplying respiratory protection is required in an oxygen-deficient atmosphere, which has less than 19.5 percent oxygen by volume.
Do compressed gas cylinders need to be secured?
The Compressed Gas Association and NFPA 1 require that compressed gas cylinders be secured to prevent them from falling or being knocked over by securing them to a fixed object like a bench or wall, by use of a restraint such as a chain, strap, or bracket.
Which type of cylinder should never be stored on its side?
Cylinders containing acetylene shall never be stored on their side. An open flame shall never be used to detect leaks of flammable gases.
