ASTM D7815-21

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

1. Scope
1.1 This practice covers guidance and direction to suppliers, recyclers, reclaimers, purchasers, and users in the handling,
transportation, and storage of Halon 1211.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical
conversions to SI units that are provided for information only and are not considered standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility
of the user of this standard to establish appropriate safety safety, health, and healthenvironmental practices and determine the
applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3. Terminology
3.1 Definitions of Terms Specific to This Standard:
3.1.1 containers—containers, n—storage vessel for Halon 1211.
3.1.2 cylinders—cylinders, n—containers of Halon 1211.
3.1.3 Halon 1211—1211, n—bromochlorodifluoromethane; a compound used to suppress a fire.
3.1.4 insulated—insulated, adj—placed in an isolated situation to protect and prevent the transfer of damage.
4. Significance and Use
4.1 This practice provides requirements for the handling, transportation, and storage of Halon 1211 encountered in distribution
through both commercial and military channels. It is intended to ensure that Halon 1211 is handled, transported, and stored in such
a way that its physical property values are not degraded. Transport may be by various means, such as, but not limited to, highway,
rail, water, and air.
5. Practice
5.1 To ensure safe handling, loading, storing, and transporting of material, personnel shall be trained in the CGA publications,
CFR regulations, and other documents, as listed in 2.2 and 2.3, respectively.
5.2 Handling:
5.2.1 Handling shall be in accordance with CGA Publication P-1P-1 and Standard for Safe Handling of Compressed Gases in
Containers and as specified by the manufacturer.
5.2.1.1 Personnel who handle or store, or both, cylinders of Halon 1211 shall be trained properly to recognize and identify the
characteristics of the product and the proper methods of safely handling full, partly full, and empty cylinders.
5.2.2 All Halon transfers between storage containers and recycling processes shall be performed by personnel trained in handling
procedures.
5.2.3 Halon 1211 recycling and transfer processes shall be in conjunction with the equipment requirements specified by the
manufacturer.
5.2.4 Halon 1211 handling shall be in nonsmoking, heater-free, ventilated areas to preclude product accumulation. Provisions shall
be made to ensure that service areas limit Halon 1211 concentrations to not exceed 1 % by volume for 1 min and 0.01 % by volume
for a time weighted exposure of 8 h.
5.2.5 Cylinders shall not be over filled. overfilled. The liquid portion of the liquefied gas shall not completely fill the container’s
internal volume and the pressure shall not exceed five fourths five-fourths the service pressure of the container at any temperature
up to and including 130 °F (54 °C). To prevent excessive pressure in accordance with Specification D7673/D7673M, the fill
density of Type 1 product within a container should not exceed that needed to achieve complete filling of the container at the
maximum envisaged storage temperature. For example, for a U.S. DOT Department of Transportation (DOT) 4BW260 cylinder,
3 3
the nitrogen partial pressure shall not exceed 129 psig at 70 °F (9.9 bar at 21 °C) for a 100 lb/ft (1602 kg/m ) fill density, which
yields a total pressure of 150 psig at 70 °F (11.4 bar at 21 °C). For this example, the safe working pressure of the 4BW260 cylinder
is not exceeded for temperatures below 131 °F (55 °C). Filling density requirements for Type II product (pure specification) are
specified in 49 CFR Title 49, Part 173.304 and 49 CFR Title 49, Part 173.305. (See Figs. 1 and 2.)
