IDENTIFICATION OF WARNINGS AND OTHER NOMENCLATURE OF
IMPORTANCE USED IN THIS MANUAL
Farr Canada uses three subsets to describe items in three degrees of importance.
The highest level of urgency is called a CRITICAL WARNING, and is identified with an exclamation point, is
red in color, and is surrounded by a double black box. A CRITICAL WARNING denotes an item of extreme
importance, and failure to heed a CRITICAL WARNING may result in bodily injury, death, severe equipment
damage, or any combination of these.
A STANDARD WARNING is identified with an asterisk, and contains information critical to the correct as-
sembly or operation of the unit. A STANDARD WARNING may also serve to alert the user to a potential
low-level injury hazard. A STANDARD WARNING is also surrounded by a double black box, but is amber
in colour.
An ALERT is identified by black text within a double black box. An ALERT contains specific information of
note that pertains to the correct assembly or operation of the unit.
