Conventions
The following paragraphs describe some of the conventions that are
used in your MTS manuals.
Hazard conventions Hazard notices are embedded in this manual and contain safety
information that is specific to the task to be performed. Hazard notices
immediately precede the step or procedure that may lead to an
associated hazard. Read all hazard notices carefully and follow the
directions that are given. Three different levels of hazard notices may
appear in your manuals. Following are examples of all three levels.
Note For general safety information, see the Safety manual included with
your system.
Danger notices Danger notices indicate the presence of a hazard which will cause
severe personal injury, death, or substantial property damage if the
danger is ignored. For example:
High intensity light and dangerous radiation are emitted by class 3B
lasers.
Viewing a class 3b laser directly or viewing it using optical instruments
will cause immediate and severe injury.
Avoid eye or skin exposure to the laser beam. Ensure that all power to the
laser is off before attempting any maintenance, service, or adjustment
procedure.
Warning notices Warning notices indicate the presence of a hazard which can cause
severe personal injury, death, or substantial property damage if the
warning is ignored. For example:
Hazardous fumes can accumulate in the test chamber as a result of
testing.
Breathing hazardous fumes can cause nausea, fainting, or death.
Ensure the chamber is properly ventilated before you open the chamber door
or put your head or hands into the chamber. To do this, ensure the
temperature controller is off and allow sufficient time for the ventilation
system to completely exchange the atmosphere within the chamber.
