Technical rules for plant safety (TRAS 120) – technical safety requirements for biogas plants

The TRAS-120 regulations define the technical requirements for biogas plants to minimise dangers such as fire, explosions and other safety-related risks. They include design requirements such as materials, sealing systems, tank and piping dimensions, and safety equipment. In addition, they contain operational specifications for monitoring gases and temperatures, handling substrates, pressure-relief systems and guidelines on what to do in the event of malfunctions or emergencies. Furthermore, the TRAS-120 guidelines specify regular inspection, maintenance and servicing of plant sections to ensure safe operation and avoid dangers.

For more information and editions, consult, for example, the Commission on Process Safety (KAS) at the German Federal Ministry for the Environment, Nature Conservation, Nuclear Safety and Consumer Protection.

• Electrically conductive surface with high adhesion values
• Special colour scheme with increased reflectance (agate grey similar to RAL 7038)
• Low methane permeation

• Customised design
• Stringent requirements for minimum pressures
• Dust-protected redundant fans
• Flame retardant (B1 acc. to DIN 4102)
• Support air monitoring
• Methane monitoring

• Verifiable structural analysis for the entire roof system
