ISO 27001 (Information Security): defines the requirements for creating and running an Information Security Management System (logical, physical and organisational security), with the aim of protecting data and information from threats of all kinds, ensuring its integrity, confidentiality and availability.

ISO 50001 (Energy Management): the standard aims at helping organisations improve their energy performance, increasing energy efficiency and reducing climate and environmental impact.

Major accident: event such as a serious spill, fire or explosion due to uncontrolled developments in activities in the presence or use of dangerous substances, that could cause grave danger for human health or the environment.

Medical Device (DM): any instrument, apparatus, equipment, machine, device, plant, reagent in vitro or for calibration, computer software, material or other similar or related product for use, alone or in culmination, on persons for one or more specific purposes of diagnosis, prevention, control, therapy or attenuation of an illness; for diagnosis, control, therapy, attenuation or compensation of a wound or handicap; for studying, substituting or modifying anatomy or a physiological process; for intervening on conception where the main desired action in or on the human body is not carried out with pharmacological or immunological means or through metabolism, but whose function can be aided by these means.

Medical gases: both gases intended to be administered to the patient (such as medical oxygen, 93% oxygen, medical nitrous oxide, medical air), and gases not intended for administration but used for other purposes, such as air and nitrogen to power surgical instruments.
