Services offered

We are happy to offer you all our services. Experience has shown that the following services may be of particular interest to you.

Explosion protection

Due to the methane content in biogas, biogas plants are subject to inspection in accordance with BetrSichV. Commissioning tests and periodic inspections are required. We are happy to offer you the following services:

Water protection

Biogas plants fall within the scope of the AwSV and must therefore be inspected at the time of commissioning and every 5 years. Ancillary systems such as used oil or fresh oil storage can also be AwSV systems requiring inspection. We are happy to offer you the following services:

Hazardous incident law

With a storage quantity of 10,000 kg (or more) of biogas, your plant falls within the scope of the Major Accidents Ordinance (12th BImSchV). This entails various obligations that you must fulfill. We are happy to offer you the following services:

Approval procedure according to BImSchG

Approval procedures in accordance with the BImSchG are usually required for the expansion of biogas plants. We are happy to offer you the following services:

Creation
As part of a site inspection, we assess the local conditions and determine the potentially explosive areas. Based on this, we develop the explosion protection concept which, as the core of the explosion protection document, contains the operating concept, the primary, secondary and tertiary protective measures, the zone classification and a final assessment of explosion safety, taking into account TRGS 725. In addition, the necessary organizational measures and inspection intervals in accordance with BetrSichV are determined and recorded in the explosion protection document. If required, we can carry out an assessment of ventilation measures in accordance with DIN EN 60079-10-1.
Additional support
We are also happy to support you in drawing up the checklist for explosion-protected equipment in accordance with Directive 2014/34/EU (ATEX) and creating a zone plan.
Necessity
The explosion protection document must be created before commissioning, as it forms the basis for the pre-commissioning inspection in accordance with Section 15 BetrSichV and the instruction of your employees.
Inspection before commissioning - Annex 2 Section 3 No. 4.1
The test must be carried out once before commissioning or before recommissioning after modifications requiring testing. In particular, the explosion protection document including zone classification, necessary further tests of the devices, protective systems, safety, control and regulating devices within the meaning of Directive 2014/34/EU with their connecting devices as well as the ventilation systems, gas warning devices and inertization devices must be checked by a person qualified to carry out the test in accordance with Annex 2 Section 3 No. 3.3.
Periodic inspection - Annex 2 Section 3 No. 5.1
The inspection is required every 6 years. In particular, the explosion protection document including zone classification and the tests carried out in accordance with No. 5.2 and No. 5.3 must be inspected by a person authorized to inspect in accordance with Annex 2 Section 3 No. 3.3.
Periodic inspection - Annex 2 Section 3 No. 5.2
The inspection is required every 3 years. In particular, devices, protective systems, safety, monitoring and control devices within the meaning of Directive 2014/34/EU and their connecting devices must be inspected by a person authorized to carry out inspections in accordance with Annex 2, Section 3, No. 3.1.
Obligation to inspect according to location
Annex 5 of the AwSV specifies the inspection dates for systems outside protected areas or provisionally secured flood areas. Annex 6 lists the inspection dates for installations within the aforementioned areas.
Inspection dates and intervals
AwSV installations must be inspected before commissioning, after significant modification, periodically and when decommissioned
Obligation to inspect
The obligation to inspect is specified for the various types of system in Annex 5 and Annex 6 of the AwSV. We would be happy to check the obligation to inspect your systems for you.
Necessity
A safety inspection in accordance with § 29 a BImSchG is ordered by the authorities. This is often already stipulated in the approval notice for your plant. However, your competent authority can also order a safety inspection, for example, if there are indications that certain safety requirements are not being met.
Procedure
Safety inspections in accordance with Section 29a BImSchG can be carried out in very different ways. Ultimately, the authority determines the scope of the inspection. This is usually regulated in the approval notice for your plant.
Inspector
Safety inspections in accordance with § 29a BImSchG may only be carried out by experts notified in accordance with § 29b BImSchG. We would be happy to inspect for you.

Preparation
The concept for the prevention of major accidents is drawn up on the basis of the requirements of Section 8 in conjunction with Annex III of the Major Accidents Ordinance (12th BImSchV). Furthermore, the requirements of the KAS-19 guideline are taken into account during preparation.
Testing or preparation
We are happy to support you in the preparation of your major accident concept. If required by the authorities, we can also check your existing incident concept. Please note, however, that we cannot review any incident concepts that we have helped to create.
Necessity
A concept for the prevention of major accidents must be drawn up for the first time before an operating area is commissioned. In the case of upper-tier operating areas, the accident prevention plan is generally integrated into the safety report. The concept for the prevention of major accidents must also be updated at least every 5 years.
Appropriate safety distance
The appropriate safety distance according to § 3 (5c) BImSchG is the distance between an operating area and a neighboring protected object and is particularly relevant for spatially significant planning according to § 50 BImSchG. The Commission for Plant Safety has published the guidelines KAS-18 and the working aid KAS-32 for calculating the appropriate safety distance. The scenarios described there serve as a guide for determining the appropriate safety distance for your company.
Safety distance for gas flares
A safety distance must be calculated for gas flares (additional gas appliances) in accordance with No. 3.8 (5) of TRAS 120. The distance must be determined from which the limit value for heat radiation of 1.6 kW/m² (at a height of 2 m) for the area occupied by persons and of 5 kW/m² to neighboring parts of the system (height of the center of the flame) is undercut.
Extent of explosion protection zones
When creating an explosion protection document, it may be necessary to determine the extent of explosion protection zones. We will be happy to carry out this calculation for you and also support you with other explosion protection issues.
