The units generate an excess pressure of max. Since 504-266 can’t be worn freely, it must be supplied externally with breathing air using a compressed air supply hose — either from a permanently installed breathing air line or via breathing air cylinders provided.

What types of compressed air cylinders are there? How do I use an air line breathing apparatus?

CFRP cylinders are the lightest and therefore offer the highest comfort. Breathing safely independent of the ambient air. This depends on the framework conditions of the mission: The colour of the jacket is optional. Given the expected physical exertion, they should be demonstrably healthy.

The compressed air tank is made of steel, aluminium or carbon fibre composites CFRP. A compressed air hose breathing system offers unlimited air supply but severely limits the radius of movement. A compressed air cylinder with a volume of 3 l short-term SCBAa pressure of bar and an air volume of approx. These devices provide a continuous air flow resulting in a high air consumption. There are three different device types: EN applies to industrial applications.

The easily visible cylinder coding according to EN provides information about the content of the cylinder and the danger emanating from it. Compressed air cylinder or airline equipment: This is to prevent hazardous substances in the ambient air from entering the mask.

Depending on the deployment conditions, you can separately choose the cylinder volume, pressure and thus the amount of compressed air.

Breathing safely independent of the ambient air

The requirements for self-contained breathing apparatus as a safety device have been defined in EN Anybody working for more than 30 minutes using heavy respiratory protective devices must therefore, for example in Germany according to BGIbe subjected to a preventative physical examination based on a defined schedule.

What conditions does the wearer of a respiratory protective device have to meet? The duration of deployment also depends on the personal air consumption of the wearer.

Self-contained breathing apparatus SCBA offer full freedom of movement but have a limited air volume and thus limit the deployment time. What do the coding and the label on the compressed air cylinder mean?

Find out here how this is implemented in practice. Working with respiratory protection is tiring — the fire service is well aware of that. Disclaimer Please select your language: Which system has which benefits? The following principle applies to the selection: Compressed air cylinders must be cleaned regularly. With normal pressure lung demand valve: What statutory requirements need to be complied with? Compressed air cylinders are available with a filling pressure of to bar.

What have consider

With overpressure lung demand valve: For example, a cylinder with a black and white colour shoulder stands for a compressed air cylinder. Fit for every mission Working with respiratory protection is tiring — the fire service is well aware of that. Find out more under Safe application. In work spaces with extremely high concentrations of hazardous substances or with lack of oxygen, self-contained breathing apparatus are the first choice.

The compressed air tank is fitted with a shut-off valve. To prevent the ingress of moisture or contaminants into the cylinder, the pressure should never be lowered below 2 bar. The colour coding only applies to the shoulder of the cylinder.
