C. REGULATORY POSITION
special nuclear material when the licensee is authorized to possess more than 500 grams of U-235, 300 grams of The characteristics of an immediate evacuation Pu, or 300 grams of U-233. This guide defines the signal described in ANSI N2.3.1967, "Immediate characteristics of an acceptable audible alarm for use in Evacuation Signal for Use in Industrial Installations this and other instances where prompt, complete Where Radiation Exposure May Occur," are generally evacuation is required to prevent serious injury from acceptable for use wherever such a system may be radiation exposure. needed or required, subject to the following:
B. DISCUSSION
1. The minimum duration of the signal should be sufficient to ensure evacuation and permit United States of America Standards Institute implementation of access control.
Subcommittee N2.1, Ionizing Radiation Symbols, Color Codes and other Identifying or Warning Devices, 2. Within a given facility or plant, the unique signal prepared standard N2.3-19671 which was approved by described in N2.3-1967 should be consistent if used in the United States of America Standards Institute on more than one location.
'The United States of America Standards Institute became 3. In some cases, plant design features or operating the American National Standards Institute, Inc., in 1969. Copies conditions may require alarms different from that of ANSI N2.3-1967 may be obtained from the American National Standards Institute, Inc., 1430 Broadway, New York, described in the standard.
