Compressed air blowing; laws and regulations

Today two countries, the US and Switzerland, have implemented requirements for blowing directly on the skin. Workers often use air guns to blow off dust and dirt during or at the end of the work day. Using compressed air this way could force air bubbles to enter the blood stream and cause a clot. Current regulations were implemented as a result of several fatal accidents of this kind.

The Machinery Directive


The EU has imposed the Machinery Directive 2006/42/EC, which includes important health and safety requirements for the design and manufacture of machinery and safety components.

Although air nozzles used in systems and machinery are covered by the Machinery Directive, these components are not affected separately. Compressed air components are not required to be CE-marked individually under the Machinery Directive; in fact, it is even illegal to do so. For machine builders who must specify that their product complies with the Machinery Directive the technical specifications for temperature and pressure, as stated in the catalog, are sufficient for integrated components such as nozzles.
