小表妹导航Compresd Gas
There are many types of compresd gas cylinders commonly found on construction sites.
Of tho compresd gass, oxygen and acetylene are among the most common and the most dangerous.
Employees that fail to u or store compresd gas properly are inviting disaster.
Improper handling of compresd gas can lead to rious fires, explosions, or releas due to pressure buildup in cylinders or reactivity with other materials.
Understanding the hazards associated with compresd gass will help us to identify the ways it can be ud safely.
Acetylene is a well-known fuel gas ud internationally in gas welding and cutting.
Even though it is very common, this gas is extremely dangerous if ud improperly.
Acetylene becomes volatile at pressures greater than 15 PSI.
That is why many of the outlet pressure gauges on an Acetylene regulators show red at pressures above 15 PSI.
An Acetylene Cylinder is rated for pressures up to 250 PSI, but this is acceptable becau the gas is dissolved in acetone.
The hazards of volatile explosion are associated with relea pressure not storage pressure.
Acetylene leaks, not matter how small, can have rious conquences.
The explosive range of the gas, when mixed with air, is from 2.5% to 82%, the widest of any commonly ud gas.
When using acetylene gas, always obrve the following procedures:

∙ 歌曲小树叶Clo the cylinder valve before shutting off the regulator, to permit gas to bleed from the regulator.
∙ Don’t open the acetylene cylinder valve more than ¾ turn.
∙ Clo valves when returning empty cylinders to storage or for refill.
∙ Acetylene cylinders are not hollow; they are packed with porous rock that is saturated with acetone.继续奔跑

∙ Always u acetylene in a well vented area.宝宝发烧吃什么
Never store cylinders near open flames or electrical equipment.
∙ Never store acetylene, or any other fuel gas, within 25 ft. (7.62 m) of oxygen cylinders.
If this paration is not possible, erect a noncombustible ½ hour fire rated partition, at least five feet high between the two gas in storage.
∙ Always cap and cure stored cylinders upright to prevent them from falling over and damaging the valve or cylinder.

Oxygen is commonly stored at pressures near 2,000 PSI. This is a huge amount of stored energy.
If a cylinder's valve stem were to be sheared off in a fall, there is enough stored energy to turn the cylinder into an unguided missile which could shoot across the shop or yard, destroying anything in its path.
Oxygen supports combustion, so it can magnify a small flame or spark into a large explosion.
Oxygen u requires special precautions:
∙ Oxygen placed under high pressure can erupt in flame or explode if it comes into contact with oil or grea; so never u oil or grea on any gas welding apparatus, including cylinder caps. Keep the torch clean and free of grea. Don't change cylinders or regulator valves unless you have clean hands. Just a little oil on your hands could cau an unfortunate explosion.
∙ Always clo down cylinder valves when you are finished using the torch.

This includes when you take a break and go to lunch. Even a pinhole leak in the ho can allow gas to accumulate in the workplace creating the potential for fire or explosion.
∙ When opening regulator valves, turn them slowly and stand to one side. If oxygen and acetylene were to mix inside the regulator under pressure, an explosion could result. The explosion could be a minor "pop" or it could destroy the regulator and injure the operator.
∙ Regularly inspect the gauges to make sure they are in proper working order to prevent possible malfunctions.
∙ Any damaged or inoperable gauges should be repaired or replaced before u.
∙ Do not u oxygen to ventilate a confined or enclod space. An oxygen enriched confined environment creates a rious fire and explosion hazard.
∙ Compresd gas cylinders are not allowed in confined spaces.
