Why are flammable gases dangerous?
All compressed gases are hazardous because of the high pressures inside the cylinders. Even at a relatively low pressure, gas can flow rapidly from an open or leaking cylinder. There have been many cases in which damaged cylinders have become uncontrolled rockets or pinwheels and have caused severe injury and damage.
Why is it dangerous if there is a fire in a room containing compressed gas cylinders?
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, 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 happens if an oxygen tank falls over?
A falling tank or vessel is very dangerous. If it falls over or is dropped, it might break, causing the pressurized oxygen to escape rapidly. This pressure can cause the tank or vessel to fly through the air. Always keep oxygen tanks or liquid oxygen vessels upright in a cart, rack, or stable base.
What color cylinder represents flammable gases?
red
Based on gas properties
| Gas property | Colour | Examples |
|---|---|---|
| Flammable | red shoulder | hydrogen, methane, ethylene, forming gas |
| Oxidising | light blue shoulder | nitrous oxide, oxygen-containing blends |
| Inert (nontoxic, nonflammable, nonoxidising) | bright green | neon, krypton, xenon |
| Toxic and flammable or Toxic and corrosive |
Can flammable gases form a flammable mixture with air?
A flammable gas is a compressed gas that can easily catch fire and continue to burn. The gas can easily form a flammable mixture with air. A flammable gas is a compressed gas that can easily catch fire and continue to burn. The gas can easily form a flammable mixture with air.
What does a flammable gas mean?
A flammable gas is a gas that burns in the presence of an oxidant when provided with a source of ignition. Flammable gasses can include methane, acetylene, ammonia, hydrogen, propane, and propylene.
Why are oil storage tanks so dangerous?
These deaths occurred while employees were gauging and thieving oil storage tanks. They experienced sudden exposure to high levels of gases. Most were killed instantly. Why they’re dangerous: Some of these gases, including benzene, are carcinogens. Petroleum gases can cause both short-term and long-term health effects.
What are the fire hazards associated with compressed gases?
What are the fire and explosion hazards associated with compressed gases? 1 Flammable Gases. Gas Concentration within the Flammable Range: The concentration of the gas in air (or in contact with an oxidizing gas) must be between its lower flammable limit (LFL) 2 Oxidizing Gases. 3 Dangerously Reactive Gases.
What are the risks of smoking while on oxygen?
Smoking while on oxygen increases the risk of fire. Fires endanger the lives of people who are on oxygen, others in the home or surrounding area and emergency personnel who respond to the fire.
What are the dangers of smoke inhalation?
This creates the danger of serious burns on the head and face if smoking materials are brought toward the mouth and burns on the remainder of the body if clothing ignites. People who require supplemental oxygen generally suffer from serious heart or respiratory diseases.
