After nearly 40 years of active business, Hanspeter and Annekäthi Rösti had the pleasure of passing their company to the local qualified roofer André Brunner and his wife Susanne in the summer of 2013, as they smoothly transitioned into retirement. André Brunner completed his apprenticeship with roofer Ernst Kuhnen in Lenk, and after several years of gaining experience in his trade in the lowlands, he worked for 10 years in federal service. Today, the company employs up to 11 full-time and seasonal employees.

Device Testing Defective electrical devices cause numerous fires and electrical accidents with personal injury each year. Since defects in electrical devices are difficult to detect without measurements, periodic inspections can significantly reduce accidents. Employers are required to maintain their electrical equipment and ensure that electrical devices do not pose a danger (Electricity Act / Accident Prevention Ordinance). With the implementation of the standard SNR 462638 (2018), electrical devices must be periodically tested! Every employer and the responsible technical manager are personally liable for the safety of employees. It is not the company that is liable, but the person responsible for operational safety. Therefore, it is not about a fine for the company but about the personal consequences of a court case with compensation claims and the risk of possible imprisonment. Contact us, we will assist you with planning and gladly submit an offer for device testing in your company!
