Full title and description

Industrial furnaces and associated processing equipment — Safety — Part 3: Generation and use of protective and reactive atmosphere gases. This part of ISO 13577 specifies safety requirements for the generation, supply and use of protective and reactive atmosphere gases that are integrated in thermo-processing equipment (TPE), and gives provisions to reduce hazards associated with atmosphere gas systems used in industrial furnaces and associated equipment.

Abstract

ISO 13577-3:2016 addresses significant hazards, hazardous situations and events relevant to the generation and use of protective and reactive atmosphere gases created by thermochemical reactions and their use in TPE when used as intended and under conditions foreseen by the manufacturer. It covers pipework downstream of and including the manual isolating valve, equipment for generating atmosphere gases, additional equipment for use of atmosphere gases in TPE, required safety devices and functional requirements for safety-related control systems; it also describes expected hazards and appropriate preventative measures.

Scope

ISO 13577-3:2016 applies to TPE in which atmosphere gases are generated or used as part of the equipment. It specifies safety requirements for pipework (from and including the manual isolating valve), generation equipment, ancillary equipment, safety devices and safety-related control functions associated with protective and reactive atmosphere gases. The standard applies to the supply of atmosphere gas, source gas, inert gas and process liquids to TPE and their removal from TPE where those elements are integrated in the equipment. Exclusions and limits include utility supplies upstream of TPE disconnects, flue gas ducting not part of TPE, semiconductor TPE, vacuum furnaces and decommissioning activities; the pressure hazard is limited to group I (see annexes).

Key topics and requirements

• Safety requirements for atmosphere-gas pipework: connections, marking, soundness/tightness, purge points, condensate drains and vents.
• Requirements for equipment used to generate atmosphere gases and for additional equipment supplying or using atmosphere gases within TPE.
• Required safety devices and functional requirements for safety-related control systems (including supervision of ignition sources and door movements on TPE).
• Measures to prevent formation of ignitable atmospheres and to manage combustible gas discharge points (including flame arrestors, pressure-relief and blow-off arrangements).
• Information for use (labelling, documentation and instructions) and guidance on anticipated hazards specific to atmosphere gas systems.
• Illustrative lists and guidance (e.g., typical protective/reactive gases in Annex B) and normative references to general TPE safety in ISO 13577‑1 and related parts.

These key topics are taken from the clause and annex structure of the standard and the related ISO 13577 series guidance.

Typical use and users

Primary users are manufacturers and designers of industrial furnaces and thermo-processing equipment, safety and process engineers, plant integrators, commissioning and maintenance personnel, conformity assessment bodies and occupational safety specialists. The standard is used when designing, installing, commissioning and maintaining atmosphere gas generation and supply systems that are integrated into TPE.
