Health & Safety and the ATEX Directive
Operators and contractors must comply with regulations laid down to ensure the safety of workers and follow installation codes of practice that are designed to reduce risk. Under UK law, the Health & Safety at Work Act makes employers responsible for ensuring the health and safety of their employees and also of the public, if they are at risk from dangerous substances or situations. The Protection of Workers at Risk from Potentially Explosive Atmospheres Directive 99/92/EC establishes minimum requirements to protect workers against hazards from explosive atmospheres.

Clause 9.3.2 of IEC 60079-14 permits cables with either thermoplastic, thermosetting or elastomeric sheath materials. Clause 9.3.1 of IEC 60079-14 requires cable inner or outer sheaths to have a tensile strength of 8.5 MPa. IEC 60079-14 permits the use of ‘thermoplastic’, ‘thermosetting’ and ‘elastomeric’ materials for the construction of cable bedding and sheathing. Examples of these materials and common identification types for cable sheathing, as defined by relevant standards.
