This article aims to provide an analysis of provisions outlined in the China industry standards GB 14193-93, specifically pertaining to liquefied gas cylinders and the requirements for their safe filling.
Liquefied gas cylinders are those cylinders designed to store combustible gases. The gas contained in the cylinders is dissipated in liquid form and require specific requirements to ensure the safe transport and filling of such materials. This document provides regulation of these requirements and endeavors to ensure the health and safety of personnel involved in the manufacture, transportation, storage and filling of these cylinders.
The scope of the document is wide and includes the latest manufacturing technologies and process requirements necessary for full compliance. It is also applicable to the filling of cylinders with liquid or compressed combustible gases, and gives guidance on their safe construction and filling. Furthermore, it is applicable to the preparation of liquid combustible gas such as liquefied petroleum gas or liquefied natural gas for the purpose of filling such cylinders.
The document outlines necessary requirements that must be implemented and maintained to ensure safety. This includes the requirements of the cylinders, their markings, and the compliance of operating personnel. It also provides guidance on what types of gasses may be lawfully filled in them. Additionally, it covers things such as the quality and quantity of the gas, suitable filling methods and the conditions in which it can be carried.
In terms of the cylinders themselves, the document outlines certain requirements such as cylinder type, material of construction, and shape. It also outlines the minimum filling pressures, together with additional requirements such as hydraulic tests and maximum permissible filling pressure, in order to ensure the cylinders can meet the relevant safety standards.
Furthermore, the document outlines the necessary markings and associated information that must be recorded and maintained. This includes both essential and non-essential technical information such as manufacture date, tare mass and test date. All this information must be clearly legible and located on the cylinder itself.
The document also outlines the density requirements of the liquefied gas or compressed gas that is used for the purpose of filling the cylinders. The gas is also required to be of a quality that is suitable for its intended use. Additionally, it must be chemically, physically and microbiologically stable.
Finally, the document also outlines the various requirements that must be understood and complied with by personnel who are operating and filling the cylinders. These include qualifications and relevant training of personnel, as well as ensuring correct and safe methods of operating a gas filling system.
Overall, the document provides clear guidance on the requirements and regulations that must be adhered to in order to fill liquefied gas cylinders safely. It is essential that personnel involved in the manufacturing, filling, storage, and transportation of these cylinders are familiar with and comply with the provisions outlined in GB 14193-93 in order to ensure the safety of all personnel involved.
