designates a degree or level of hazard seriousness.
The signal words for product safety signs are
“Danger”, “Warning”, “Caution” and “Notice”.
These words are defined as:
DANGER indicates an imminently hazardous
situation which, if not avoided, will result in
death or serious injury.
!
DANGER
!
WARNING
WARNING indicates a potentially hazardous
situation which, if not avoided, could result in
death or serious injury.
!
CAUTION
CAUTION, used with the safety alert symbol,
indicates a hazardous situation which, if not
avoided, could result in minor or moderate
injury.
CAUTION, used without the safety alert
symbol, is used to address practices not
related to personal injury.
CAUTION
NOTICE
NOTICE is used to address practices not related
to personal injury.
Qualified Person
For the purposes of this manual, a qualified
person, as stated in NFPA 70E®, is one who has
