Maintenance

The employer is responsible for occupational safety and health protection in a company. He is responsible

for ensuring that no accidents occur and that the health of employees is not harmed.
The risk assessment for SMEs is addressed to companies with special risks and less than 10 employees. According to the EKAS directive on the involvement of occupational physicians and other occupational safety specialists (ASA directive), companies with special hazards and less than 10 employees can prove systematic assessment of hazards or the measures taken by simple means, e.g. with completed checklists.
For companies with 50 or more employees as well as companies with special hazards and 10 or more employees, an operational safety system (ASA) is mandatory.

As in this area occurs a dangerous, explosive atmosphere as mixture of air and flammable gases, vapors and fogs.
