Why CSA?

Trust in CSA Group’s decades-long experience helping safeguard the health of consumers, workers, and the environment

CSA Group produced its first code for mechanical & industrial equipment in 1938. Today we offer a portfolio of safety codes and standards that contribute to public confidence, injury prevention, and consumer and workplace safety.

Because we work closely with manufacturers and provincial and territorial regulators across the country on standards development, many of our codes and standards in this and other subjects are referenced in legislation and other guidance documents. These include the ASME A17.1/CSA B44 - Safety Code for Elevators and Escalators, CSA B51 - Boiler, Pressure Vessel, and Pressure Piping Code, and CSA B52 - Mechanical Refrigeration Code.
