SECO is responsible for the legislation of product safety:

Legal basis
Market surveillance takes place within the scope of enforcement of the Swiss Federal Statute on Product Safety (PrSG).
Market surveillance of pressure vessels and pressure equipment is based on the Product Safety Ordinance (PrSV) and the Pressure Vessel Ordinance or Pressure Equipment Ordinance, which reflect the corresponding European guidelines.
Reporting suspected non-compliance
Reports about (potentially) non-compliant pressure equipment can be submitted to SECO or directly to Market Surveillance of Pressure Equipment using this form.
Market Surveillance will then perform the necessary investigations.
