Here are some of the most common variations of hazard signs that you
might see in the workplace and what they mean.
BIOHAZARD
This sign indicates the presence of harmful microorganisms such as
viruses, bacteria and other toxins. This hazard sign is frequently found
on containers for the disposal of medical waste such as used syringes.
LASER
Devices that depend on high-powered lasers must bear the warning sign
below. Anyone entering areas where lasers are used should be
equipped with eye protection and avoid looking directly into the source.
CORROSIVE
When this hazard sign is present, workers must take care to
use specialized safety gloves when handling corrosive materials, as they
can burn or dissolve skin and other substances on contact.
RADIOACTIVE
The hazard sign below announces that radioactive materials are present
and anyone working in the area should be protected with radiation suits.
HIGH VOLTAGE
Equipment labeled with this hazard sign uses or generates
enough electricity to seriously injure or kill a person. Only trained and
authorized technicians should be allowed to access this area.
HOT SURFACE
Anything bearing the hazard sign below can become extremely hot to
the touch. Workers should avoid it or use caution that they do not burn
themselves or others.
POISON
Materials that have the symbol shown on the hazard sign below
are poisonous and should not be swallowed, inhaled or handled without
protective gloves. This hazard sign may also highlight any area where
poisons might be present.
FLAMMABLE
Anything marked with the hazard sign below needs to be kept away from
open flames, heat sources and sparks. Flammable materials are in
danger of sudden combustion and can cause explosions.
WET FLOOR
This hazard sign can be found in practically any work environment and is
used to mark an area where the floor might be wet, has just been
recently mopped or has an increased risk of spills.
EXTREME COLD
Often found in chemical storage areas, this hazard sign indicates
extremely low temperatures. Care must be taken not to expose skin or
other sensitive items to these cold conditions.
MOVING VEHICLES
Whether forklifts, trucks or another type of vehicle, the hazard sign
below alerts workers that heavy equipment passes through the area
frequently. Anyone on foot should stay in designated pedestrian
walkways and stay alert while in the area.
Hazard signs are a prevalent sight in laboratories and industrial
workplaces. The information they convey is crucial for workplace safety,
but they may not always be familiar to those working there.
