Between shutoff valves before disconnecting the liquid transfer line from the container.
What is a gas venting system?
Gas venting is the process of allowing unwanted gaseous by-products to exit an underground system. Without proper venting, underground systems run the risk of faulty operation or even explosion when the gases build up. It is also a critical safety requirement when workers are doing underground construction.

No flammable liquids, combustible, corrosive or oxidising material should be stored within 3m of an LPG store. Compressed oxygen must be kept 10m away from all flammable gases; these include propane, butane and dissolved acetylene.
Why are LPG gas cylinders stored outside?
Fire and Explosion Hazards
An outdoor cylinder store is especially recommended for flammable and oxidising gases because the natural ventilation helps to keep any leaked gases within explosion limits.
Why is LPG stored in cylinders?
LPG vapour is heavier than air, so any leakage will sink and accumulate nearby areas as LPG expands rapidly when its temperature rises. A container is filled with sufficient space to allow for such expansion.
What are the ventilation requirements for storage rooms?
In regard to mechanical exhaust ventilation systems, they should consistently provide at least six air changes per hour as a baseline of how well-ventilated your storage rooms need to be. Other local exhaust systems will become necessary if processes like dispensing take place within the storage area.

Does LPG gas produce carbon monoxide?
LPG emissions may contain considerable amounts of CO. When engines operate in enclosed spaces, such as warehouses, buildings under construction, or tunnels, carbon monoxide can accumulate quickly and reach concentrations which are dangerous for humans. It causes headaches, dizziness, lethargy, and death.
How do you ventilate natural gas?
Shut off the gas at the appliance's supply line—or, if you cannot identify the leaking appliance, shut off gas at the meter or service valve only. When you are certain the gas is off and all ignition hazards are eliminated, ventilate by opening windows. Never ventilate while personnel are inside.
How do you ventilate a room with a gas heater?
Flues and ventilation
If you have an open flue heater, let fresh air flow through the room when the heater is on. Open-flued heaters use air from inside the house – the same air that you breathe. The heater pulls the air through an opening, to feed a gas flame.
What are the different types of gas venting?
Gas appliances are divided into four venting categories based on vent operating pressure and whether they are condensing or non-condensing. Category I is negative pressure, non-condensing. Category II is negative pressure, condensing. Category III is positive pressure, non-condensing.
What are the two types of venting?
The vent valve is a device installed to prevent negative pressure (e. g. as a result of surge pressures) in a piping system. Vent valves are also installed at the highest points in a piping, system downstream of shut-off elements or pumps, and at the highest points in domestic installation systems.

Suffocation (asphyxiant) hazard - if allowed to accumulate to concentrations that reduce oxygen below safe breathing levels. Contact with liquefied gas can cause damage (frostbite) due to rapid evaporative cooling. Eye contact Contact with liquefied gas may cause frostbite.
Is LPG a hazardous material?
LPG vapours can run for long distances along the ground and can collect in drains or basements. When the gas meets a source of ignition it can burn or explode. Cylinders can explode if involved in a fire. LPG can cause cold burns to the skin and it can act as an asphyxiant at high concentrations.
What are the hazards of LPG gas?
Store cylinders in well-ventilated areas designated and marked only for cylinders. Store cylinders in an upright position (includes lecture bottles). Empty cylinders should be clearly marked and stored as carefully as those that are full because residual gas may be present. Keep valves closed on empty cylinders.

While stores can be either inside or outside, outdoor storage for gas cylinders is best practice. Some of the biggest risks when storing compressed gases in cylinders are leaks, and this is the key reason why indoor storage of gas cylinders should be avoided wherever possible.
Should gas cylinders be inside or outside the house?
Natural and LPG gas need oxygen to burn. But not enough oxygen in a room or in a partially enclosed area with limited ventilation can cause other gases to build up and can be dangerous.
Does LPG need oxygen?
At higher temperatures, propane burns in air, producing carbon dioxide and water as byproducts, making it a valuable fuel. Ans. Incomplete propane combustion occurs when there is insufficient oxygen to complete the combustion of LPG, resulting in the production of water, carbon dioxide, and carbon monoxide.

Indoor storage should be avoided whenever possible and limits apply. LPG (propane) gas cylinders must always be stored upright with valves closed, when not in use. Gas cylinders must be prevented from falling and protected from impact and damage. Storage limits on quantity may apply and placarding may be required.
How do you store LPG cylinders at home?
The pressure of the cylinder gas varies between 2 and 3 bars depending on the ambient temperature; however, the operating pressure of the cylinders is designed to be 17.5 bars.
What pressure is LPG stored at?
There are holes between the LPG cylinder bottom ring and the body. Primary purpose of the holes is for circulation of air between surface and cylinder. Furthermore, the water between the body and the ring will shorten the life of the cylinders as it will cause corrosion. Damage from water can cause gas leakage.
Why do LPG cylinders have bottom holes?
The pressure at which LPG becomes liquid, called its vapour pressure, likewise varies depending on composition and temperature; for example, it is approximately 220 kilopascals (32 psi) for pure butane at 20 °C (68 °F), and approximately 2,200 kilopascals (320 psi) for pure propane at 55 °C (131 °F).

Does LPG cause air pollution?
Burning of LPG involves both physical and chemical changes because when LPG comes out of the cylinder and is converted from liquid to gaseous state it is a physical change. When the gas burns in the air, it produces carbon dioxide and water, and this process cannot be reversed using any physical method.
Does LPG burn in air?
There's no national code for gas venting in the United States. Generally, in the U.S., you don't have to vent a residential gas range to the outside. But, we recommend that you buy a range hood to vent contaminants from your gas range to outside your home.
Does natural gas need to be vented?
Turn on Those Fans
Ceiling fans prompt healthy air circulation and movement by pushing away stale air and fumes, which is why you should keep a fan running whenever you're in the room. As a bonus, running your ceiling fan creates a windchill effect on the skin, causing you to feel cooler than the room's temperature.
How do you ventilate a room from fumes?
Even with this safety feature in place, it is still possible for an indoor propane heater to expose you to severe levels of CO. Keep a window cracked open one to three inches while the heater is running to ensure proper ventilation.

What is a gas venting system?
Each room in your home has at least two vents: supply vents blow conditioned air into the room, while return vents draw indoor air back into the HVAC for reconditioning (like your nose and mouth).
What are the two vents in a room?
Natural ventilation is a passive ventilation system that relies on air movement through open windows or doors to exchange stale indoor air with fresh outdoor air. This type of ventilation is typically the most energy-efficient, as it does not require mechanical systems or energy inputs.
What is the most efficient type of venting system?
One of the main dangers of unvented tanks is the risk of deformity or tank rupture. As fuel is consumed from the tank, a vacuum is created which can cause the tank to collapse. This can lead to damage to the tank itself and potentially even cause a fuel leak.
What happens if a gas tank is not vented?
It is not safe to keep an LPG cylinder inside a closed door cabinet below the kitchen platform. The cabinet will trap heat and moisture, which can create a fire hazard. The LPG cylinder should be stored in a well-ventilated area, away from heat sources and flammable materials.
