Refrigerant Safety Compliance

Bacharach’s range of refrigerant leak detectors help you gain refrigerant safety compliance for ASHRAE 15, CSA-B52, BS EN 378 and others.

Refrigerant safety compliance for mechanical rooms, chillers, walk-in freezers and cold storage facilities, protecting your staff, customers, equipment and bottom line.

It’s important to ensure the safety of your staff, customers and equipment when it comes to using refrigerant- especially with asphyxiation and toxicity risks as well as fire and explosion. Achieving compliance with safety standards like ASHRAE 15, CSA-B52 and EN 378 is essential. For areas of your operation where there is a high refrigerant emission risk such as mechanical rooms, chillers, walk-in freezers and cold storage facilities, a high performance diffusion or aspirated refrigerant detection system is essential.

Compliance Standards


ASHRAE (American Society of Heating, Refrigerating and Air Conditioning Engineers) is a US organization devoted to advancing HVAC/R. The ASHRAE Standard 15 documentation establishes procedures for operating equipment and systems when using refrigerants- which are compiled in ASHRAE Standard 34 along with naming and safety classifications based on toxicity and flammability data.


The CSA Group (formerly the Canadian Standards Association) has produced the CSA B52 2018 Edition to minimize the risk of personal injury by providing minimum requirements for the design, construction, installation, inspection, and maintenance of mechanical refrigeration systems and volatile direct refrigeration systems.

BS EN 378

The BSI (British Standards Institute) document BS EN 378-1:2016 relates to refrigerating systems and heat pumps providing safety and environmental requirements, basic requirements, definitions, classification and selection criteria. The standard is intended to minimize possible hazards to persons, property and the environment from refrigerating systems and refrigerants.
