Instrument Markings and Symbols
explains the symbols used on Thermo Fisher Scientific instruments. Only a few of
them are used on the AI 3000/AS 3000 II. See the asterisk.
LIFTING HAZARD.
This symbol indicates two or more people are required to
lift the object to prevent a physical injury, which
could
or
may
occur.
MATERIAL AND EYE HAZARD.
This symbol indicates that eye damage
will,
could, or may
occur. Eye protection must be worn.
RADIOACTIVE HAZARD.
This symbol indicates that the presence of
radioactive material
could, or may
occur.
READ MANUAL.
This symbol alerts you to carefully read your instrument’s
operational instructions before usage to ensure your safety and the
instrument’s operational ability. Failing to carefully read the instructions
could
or
may
put you at risk for a physical injury.
TOXIC SUBSTANCES HAZARD.
This symbol indicates that exposure to a
toxic substance
will
,
could
,
or
may
cause personal injury or death.
This is the general warning symbol that the ISO 3864-2 standard refers to as
the general warning signal to prevent personal injury. It is a triangle with an
exclamation mark that precedes the
WARNING
safety alert word. In the
vocabulary of ANSI Z535 signage, this symbol indicates a possible personal
injury hazard exists if the instrument is improperly used or if unsafe actions
occur. We use this symbol and another appropriate safety symbol to alert to an
imminent or potential hazard that
could cause personal injury
.
