Many modern special structures, such as places of assembly, restaurants, underground car parks and office buildings, require hygiene inspections according to VDI 6022, the code of practice for heating, ventilation and air-conditioning systems and units (HVAC systems). The topic is indeed a significant one, as inadequate hygiene in HVAC systems offers ideal breeding-grounds for micro-organisms, causing irritation of mucous membranes, headaches, lack of concentration, asthma, allergies and even infections.
Given this, the law demands that HVAC systems be planned and operated in a manner preventing any health hazards or negative impacts on the well-being of users. The relevant requirements are set forth in various guidelines and standards, in particular VDI 6022. Our experts support the owners and manufacturers of HVAC systems in meeting the requirements of the guideline. Contact us for a non-binding offer.
Under the German Regulation on Health and Safety in the Use of Work Equipment (Betriebssicherheitsverordnung, BetrSichV) and/or the German Workplace Safety and Health Regulation (Arbeitsstättenverordnung, ArbStättV), the owners of HVAC systems shall have the functioning of their systems inspected at regular intervals. The objective of these inspections is to prove the safety of both the air supplied by and the operation of the HVAC systems. In VDI 6022 these inspections are called “hygiene inspections”. Hygiene inspections must be carried out initially when the system is first taken into service and thereafter periodically every 2 years (for HVAC systems with air humidifier) or 3 years (for HVAC systems without air humidifier).
Individuals who have passed hygiene training according to VDI 6022, Part 4, Category B are qualified to perform servicing, inspection and maintenance of HVAC systems. In our hygiene training according to VDI 6022, Part 4, Category B, we familiarise your employees with the hygiene requirements for HVAC systems and the necessary hygiene inspections, and qualify them to carry out the activities of the “Hygiene Checks” independently under their own responsibility.
HVAC systems in buildings with particular hygiene requirements (e.g. hospitals) must meet special design-related requirements. Our experts support manufacturers and assess HVAC systems, components, materials, the design implementation and the suitability for the specified purpose on the basis of VDI 6022.
