What does a Compressed-Air Works Officer do?
A Compressed-Air Works Officer (Druckluftbeauftragter) supervises work carried out in compressed air, such as caisson and tunnelling work in pressurised chambers. The role is governed by the Druckluftverordnung (DruckLV), which sets the requirements for pressurised work, the operation of locks, and the protection of the workers exposed. The officer is the responsible supervisor on site for everything that happens inside and around the pressure chamber.
The central tasks are the management of the air lock and the decompression schedule, ensuring that pressurisation and decompression follow the tables and procedures of the DruckLV so that workers are not exposed to decompression sickness. The officer controls who may enter, monitors pressure and time of exposure, and records both for every worker. Fitness to work is critical: only workers with a valid medical clearance under the occupational medical regime (closely linked to the ArbMedVV and the DGUV provisions on hyperbaric work) may enter, and the officer enforces the limits on pressure, duration, and frequency of exposure.
The officer also coordinates emergency provisions, including the availability of a treatment lock and medical support for hyperbaric exposure, and the instruction of workers under § 12 ArbSchG. They keep the logs that prove each shift stayed within the legal decompression and exposure limits, which are the primary evidence for the supervisory authority and the accident insurer in case of an incident. The wider duty to assess hazards under § 5 ArbSchG and the BetrSichV applies to the equipment used.
Core duties of the Compressed-Air Works Officer
- Supervise all work performed in compressed air on site under the Druckluftverordnung (DruckLV).
- Operate and oversee the air lock, controlling entry and exit of workers.
- Manage pressurisation and decompression strictly to the DruckLV schedules to prevent decompression sickness.
- Verify valid fitness-to-work medical clearance before any worker enters (linked to ArbMedVV).
- Enforce limits on working pressure, exposure duration, and frequency per the DruckLV.
- Record pressure, time of exposure, and decompression for every worker on every shift.
- Ensure availability of a treatment lock and emergency medical support for hyperbaric exposure.
- Instruct workers on the hazards of compressed-air work under § 12 ArbSchG.
- Coordinate the inspection of pressure equipment and locks under the BetrSichV.
- Maintain logs as evidence for the supervisory authority and the accident insurer.
When is a Compressed-Air Works Officer required?
Whenever work is carried out in compressed air above the pressure threshold of the Druckluftverordnung, the employer must ensure competent supervision of the pressurised work. This typically arises in tunnelling, shaft sinking, and caisson foundation work where the working chamber is held under overpressure to keep out groundwater. The DruckLV requires that such work is led by a responsible person with the necessary expertise and that medical and emergency provisions are in place before work starts.
The officer must have the technical knowledge of lock operation, decompression schedules, and the physiology of hyperbaric exposure that the role demands. Medical surveillance of the workers is mandatory: only persons with a current fitness clearance may be exposed, and the responsible occupational physician for hyperbaric work is involved. The employer notifies the competent authority of the pressurised work, keeps the required logs, and ensures the equipment, including the locks and the treatment chamber, is inspected. The appointment and the qualification evidence should be documented and held available.

How CIVAC supports the Compressed-Air Works Officer role
CIVAC gives the Compressed-Air Works Officer a workspace built around evidence and deadlines. Task templates capture the pre-shift checklist required by the DruckLV: lock readiness, treatment-lock availability, and worker fitness clearances. Per-worker exposure and decompression logs are stored as structured documentation with a complete audit trail, ready for the supervisory authority and the accident insurer after any incident. Reminders track the expiry of each worker's medical fitness clearance and the inspection dates of locks and pressure equipment under the BetrSichV. The training library holds instruction material under § 12 ArbSchG. All exposure and health-related records stay on EU data residency infrastructure within the European Economic Area.
