1
– Do not allow children to use or handle any handheld LASERS. Furthermore, only
allow adults to use Hand-Held LASERS after they have understood the
responsibilities and risks involved.
2 – Never point a LASER at anyone, especially at their face. Even temporary
exposure can cause significant and permanent damage to the eye. This is
especially true of this 1,000 mw BLUE LASER. LASERS are designed to point at
inanimate objects.
3 – Always be conscious of where you're pointing. Avoid aiming a LASER at any
reflective surfaces. Unintentionally reflected beams can easily result in severe
consequences from accidental indirect exposure.
4 – Never use your LASER in the vicinity of airports, highways, construction
sites or anywhere individuals need to constantly pay attention to their work for
their own safety. A split-second distraction, a sudden LASER light in a plane
cockpit, for example, can be disastrous. In addition,
with BLUE LASERS – even at great distances
– can cause eye damage to the pilot of an aircraft, or the driver of a vehicle,
which in turn can result in loss of control and subsequent loss of life.
5 – Be especially cautious around high-powered LASERS, like green handheld
LASERS used for stargazing. They are far stronger than the conventional red
LASERS commonly used during lectures. The 1,000mw blue LASER is extremely
dangerous on two counts; 1) its high power, and 2) the cumulative detrimental
effect of exposure to the blue wavelength.
6 – Do not purchase a
handheld LASER at all if it does not
identify its
class or power.
7 – Do not purchase a handheld LASER if it does not have a caution or danger
sticker on it identifying its class or its power output. Never remove these
warning stickers.
8 – Always post warning
posters if you are going to be using any LASER over 50mw where the general
Public can view the beam or its reflections. You must be a Certified LASER
Operator and have a permit in most States to conduct LASER Light Shows in dance
clubs or in other public places.

-
Prolonged exposure to blue LASER
light can alter and have a diminishing effect on a person's perception of the
color green.
-
The blue wavelength can cause a
distinct biochemical action in the release of free radicals which are then
effectively absorbed by red blood cells in the capillaries. Blue LASER light,
445nm or 470nm is absorbed more effectively by retinal
tissue compared to 532nm green or 650nm red LASER light.
-
Direct or indirect skin
exposure to blue LASER light is also harmful. The MPE (Maximum Permissible
Exposure) for skin for a 3mm beam of this wavelength is approximately 200mw/CM2.
This LASER can easily generate a
power density (irradiance) of about 15 Watts/CM^2.
Therefore, this laser's beam
exceeds the skin exposure MPE by ( 15 / 0.2 ) =
75 times. At this level of irradiance, skin
exposure to the intense blue LASER light can cause
delayed-onset necrotizing tissue damage, and
can
possibly cause cancer. Do not allow bare skin to be exposed, including
your face when wearing safety goggles, to light diffusely reflected from any
surface closer than several inches.
-
This LASER
is a thousand times stronger than sunlight on skin and any type of
exposure should be avoided whether it be from the
collimated beam or close
exposure to its bright diffused reflections.
-
Blue light hazard can cause
BLINDNESS and not just color perception issues. The
power of this LASER is no joke. At 1 WATT this is a
Class IV Laser. Do not allow
unprotected eye exposure to diffusely scattered light from the beam terminating
on a wall, the floor or other flat surface from this LASER closer than 3 feet.
-
Accidental
eye exposure will definitely result in
instant retina tissue damage even within just
milliseconds of exposure. This means that
the normal "aversion reaction" to bright light cannot
protect you – by the time you react and turn away,
the damage will already have been done.
Direct eye contact with the beam or reflections of it will cause instant
permanent damage and blindness. In some cases, blindness may take a day or
longer for the onset. Unlike instant injury from a bright flash of a red or
green LASER, this effect is cumulative.
It is also
possible that such an exposure could cause retinal degeneration and even loss of
vision later in life.
-
Accidental exposure is a very
serious issue and would like to reiterate that extreme care, proper safety gear
and the necessary safety precautions be followed METICULOUSLY when using this
LASER. It is not a
toy, it is a high power
Class IV 1 Watt LASER. In addition, this LASER must NEVER be used to play
with your pets. At close range, this Class 4 beam will cause immediate and
irreversible retinal damage. Close proximity to the beam's diffused reflection
off floors and walls could potentially cause injury and blindness. In general,
DO NOT aim this LASER on yourself, on your skin, on animals, on others or target
moving vehicles and airplanes.
-
This Blue LASER should only be
handheld by individuals who have appropriate LASER safety training and product
familiarity in using
Class 4 LASERS. For more information
and guidance please refer to ANSI Standard Z136.1 from the American National
Standards Institute on the safe use of LASERS.
