ASME A13.1-2015 pdf download.Scheme for the ldentification of Piping Systems.
ASME A13.1 is intended to establish a common system to assist in identification of hazardous materials conveyed in piping systems and their hazards when released in the environment.
This scheme concerns identification of contents of piping systems. It is recommended for the identification of piping systems used in industrial, commercial, and institutional installations, and in buildings used for public assembly. It does not apply to buried pipelines nor to electrical conduits.
Existing schemes for identification shall be considered as meeting the requirements of this Standard if
(a) such schemes are described in writing
(b) employees are trained as to the operation and hazards of the piping systems
2 DEFINITIONS AND REFERENCE
2.1 Piping Systems
For the purpose of this Standard, piping systems shall include piping of any kind including fittings, valves, and pipe coverings. Supports, brackets, or other accessories are specifically excluded from applications of this Standard. Piping is defined as conduits used to convey, distribute, mix, separate, discharge, meter, control, or snub fluid flows.
15) 2.2 Materials
2.2.1 Flammable. This classification includes fluids, which, under ambient or expected operating conditions, are a vapor or produce vapors that can be ignited and continue to burn in air. The term thus may apply, depending on service conditions, to fluids defined for other purposes as flammable or combustible.
2.2.2 Combustible. This classification includes fluids that can burn, but are not flammable.
2.2.3 Oxidizing. Oxidizing fluid is any gas or liquid that may, generally by providing oxygen, cause or contribute to the combustion of other material more than air does.
2.2.4 Toxic and Corrosive. This classification includes fluids that are corrosive or toxic, or will produce corrosive or toxic substances when released.
The applicable GHS’ pictogram as illustrated in Fig. 1 may be included as part of the legend.
Where piping is connected to containers that are labeled in accordance with GHS requirements, a corresponding label on the piping may be provided. The corresponding label should contain at least the product name or identifier, the pictogram, the signal word, and the physical, health, and environmental hazard statement(s).
3.2 Color
Color should be used to identify the characteristic hazards of the contents. Color should be displayed on, or contiguous to, the piping by any physical means, but its use shall be in combination with legend. Color may be used in continuous, total length coverage or in intermittent displays. Colors preceded by the word “Safety” shall meet the requirements of ANSI Z535. 1 (see Table 2).
3.3 Visibility
Attention shall be given to visibility with reference to pipe markings. Where pipelines are located above.
