Labelling Refrigerant Cylinders: Why Set Up National Legislation on Labelling Refrigerant Cylinders? - Ozone Action Technical Brief

This document is a technical brief guiding governments and National Ozone Officers to establish mandatory labelling for refrigerant cylinders to support Montreal Protocol controls and ensure safety across the cylinder life cycle. It explains how labels enable clear identification, hazard communication, and trade monitoring, referencing alignment with GHS and UN transport rules (e.g., ADR, RID, IMDG, ICAO) and detailing required elements such as product identifiers, UN numbers, pictograms, signal words, hazard and precautionary statements, and supplier details. It outlines cylinder conformity markings and certification systems (π, DOT, GB), distinguishes refillable and non-refillable cylinders, and summarizes EU, Turkish, and Bahraini practices. It defines regulatory levers—compulsoriness, explicitness, standardization—and presents enforcement case studies and label templates to aid compliance and market surveillance.
