1.3 Safety Messages
This safety section contains detailed explanations about the different kinds of safety
messages used in this operating manual.
ANSI Z535.6 specifies four different types of safety messages:
Supplemental directives
Grouped safety messages
Section safety messages
Embedded safety messages
Supplemental directives instruct readers to read an entire manual or direct them to specific
safety information contained in the operating manual or from other sources. Supplemental
directives usually appear at the beginning of a safety messages section of a chapter.
Grouped safety messages provide a general description of the risks involved in using the
Argus Ball Valve and how to minimize these risks. Grouped safety messages are included in
Section 2.1 Grouped Safety Messages and in some safety messages section of a chapter.
Section and embedded safety messages caution against residual risks that may occur
during intended and non-intended (reasonably foreseeable misuse) use of the Argus Ball
Valve. Furthermore, section and embedded safety messages provide information on
avoiding hazards that may be caused by different working situations and hazardous areas
within the product life cycle.
Section safety messages are included in the safety messages section of a chapter.
Embedded safety messages precede an action step that may pose an especially severe
hazard.
