The new 9th Edition for CGA C7, “Guide to the Preparation of Precautionary Labeling and Marking of Compressed Gas Containers,” was issued on 10/21/2011. The standard covers use of precautionary labels to warn of principal hazards. It also includes general principles and illustrative labels for several types of gases, both industrial and medical.
Illistrative labels are provided for Asphyxiant gases, Flammable gases, Flammable liquids, Pyrophoric materials, Oxidizing gases, Cryogenic liquids, Toxic (poison) liquids and gases, Toxic (poison) corrosive liquids and gases, Toxic (poison) oxidizing and corrosive gases, and Corrosive liquids and gases.
Changes to this new edition of CGA-C7 include an addendum that provides guidance for compliance with the Globally Harmonized System of Classification and Labeling of Chemicals (GHS).
The GHS is a system for standardizing and harmonizing the classification and labelling of chemicals. It is a logical and comprehensive approach to:
- Defining health, physical and environmental hazards of chemicals;
- Creating classification processes that use available data on chemicals for comparison with the defined hazard criteria; and
- Communicating hazard information, as well as protective measures, on labels and Safety Data Sheets (SDS).
It was developed by the United Nations but the GHS itself is not a regulation or a standard. It is intended to provide countries with the regulatory building blocks to develop or modify existing national programs that address classification of hazards and transmittal of information about those hazards and associated protective measures. This helps to ensure the safe use of chemicals as they move through the product life cycle from “cradle to grave.”
