Safe storage of gas cylinders for gas chromatography analysis

It’s generally not easy to keep them separated in one room!

It can be placed in a specially built shelter outdoors, away from sources of fire and direct sunlight

Gas cylinder cabinets can be purchased for separate storage; these cabinets are equipped with ventilation systems.

Special storage rooms are usually built outdoors! If it is placed indoors, it is not safe and cannot pass safety inspections!

Our company has built a gas cylinder room downstairs using plywood, which protects against rain and sunlight while also ensuring good ventilation

Here is a brief introduction to our facility: Considering the safety issues related to gas cylinders, we have built a small, simple shed outside the laboratory; it is made of iron and well-ventilated. However, during the fire safety inspection, it was determined that the site did not meet the fire protection standards, and the design team needed to be asked to select a new location for the design. After consulting with the fire department, we chose a new location to build a small cylinder room, which contains cylinders of three types: hydrogen cylinders, compressed air cylinders, and nitrogen cylinders. The roof is a lightweight one, with ventilation openings on the sides at the top. An explosion-proof wall is built along the side facing the road; the door is not oriented towards the road, and another explosion-proof wall is constructed about 1 meter away from the door entrance. The door is locked at all times! There are no electrical appliances such as lights inside the house. It was quite troublesome; it’s only now that it has passed the fire safety inspection! !

We have a separately designed storage room next to the laboratory dedicated to storing gas cylinders; that’s how our laboratory is set up. The warehouse should have good ventilation; it’s sufficient to regularly check for leaks of hazardous gases such as H2, and generally there are no issues

Our unit is placed in a dedicated gas cylinder cabinet in the next room.

Ensure gas cylinders are protected from sunlight, kept well-ventilated, away from sources of fire, and taken care to prevent them from tipping over

I’ve learned that there are still issues with the placement of gas cylinders in our company; it needs to be fixed!

Regardless of the process requirements, its setup must first take into account the safety requirements for hazardous chemicals as well as fire safety requirements.

The scientific approach is to establish a dedicated cylinder storage room outside the laboratory that meets relevant safety requirements, with personnel possessing appropriate safety knowledge and skills responsible for managing it. Note that different gas cylinders should be placed in separate rooms.

The gas cylinders used in our company are mainly oxygen cylinders and nitrogen cylinders; a separate enclosed room is designated for them, equipped with exhaust fans, and surrounded by solid concrete walls.

Place it outdoors, implement measures to prevent the bottles from falling over, and protect it from direct sunlight – that’s all. 1# hw197358

Our company is studying this issue; I wonder who is correct? Learn from it. Let me share my own views: First, gas cylinders should be stored separately (flammable materials and oxidizing agents must not be kept together), with a certain safety distance maintained between them. Second, it is essential to ensure good ventilation and protection from sunlight. Third, the cylinders should be locked to prevent them from being moved around casually.

It must be placed outdoors, in a structure built to protect it from sunlight and rain, equipped with devices to prevent falls, and featuring separate areas for full and empty bottles. The fluid is transported through pipes into the analysis room. This ensures successful approval of the safety facilities ； It also ensures the safety of the analysis room.
