Priority1lss/SafetySite




Description.
The Safety
Site is one of a series of compact hazard warning
beacons for professional use. Specific domains of
use include:Emergency Services, Police, Fire, Rescue
and Ambulance, Traffic Management,Accident Warning,
Trucking, Transport Roadside Breakdown, Industrial
Safety ,HazMat Spills,Helicopter Landing Zones,Private,
Commercial and Military, Mining, Personal and Family
Protection and Aviation Runway Lighting.
The Safety Site uses a
Superbright LED that is magnified by a special lens
that projects it's beam forward at a great distance.

Evaluation Results & Conclusions...
Ease of Use
Fair . Requires some learning. There is a
flat but visible control 'pad' that somewhat characterizes
the use model. Pressing on the word 'Modes' elicits
a turning on of the unit to its first setting 'Comet'
(120fpm). Additional presses advance to the next mode.
The process is relatively easy to learn but hardly
one that one would care to commit to memory.The mode/activation
button has no haptic or tactile feedback, so first-time
users must figure out for themselves that any region
above and including the word Modes is active and that
pressing the word 'Off' has no effect. Indeed the
label for the activation/modes button is not really
a label but a minimized instructional graphic. We
found the 'button' too small to be quickly activated
with thick winter gloves or hazmat gloves but it was
fine to use bare handed.
Replacing the three C size batteries entails removing
the gasket-sealed front refractor from the body section
by removing three Phillips head screws. Batteries
are then simply replaced and the two parts reassembled.
This is an operation reserved for down time
and not something to be performed on the site of an
emergency. This is especially true since delicate
wires are exposed that connect the LED module to the
battery compartment.

Task performance optimization
Excellent . Accomplishes the task of making
an otherwise unnoticeable scene very noticeable- signaling
caution, hazard or a need for help. Since Safety Sites
are available as a kit, we tested the ease of use
of a kit in a simulated roadside breakdown.
The kitbag design encourages a quick removal
from an automobile trunk (boot). Once out of the vehicle,
a single zipper opens the entire top , allowing for
removal of the flares. We walked away from the rear
of the vehicle and individually activated each flare
before placing it on the tarmac. Once activated the
Safety Site is hard to overlook. The projected bright
read beam of light it sends out can blind at close
range and is very noticeable at 1.5 miles. A 1/4X20
threaded bushing on the back of each unit encourages
mounting to safety triangles as well as barriers-
both are highly recommended options for traffic control.
Upright on the ground or laid on its back the Safety
Site makes a formidable helicopter or airplane landing
beacon.
We performed two additional simulations:
A) Pushover Test - The angle at which the flare would
fall over
B) Wash Away Test - Amount of water pressure at 12"
for 3 seconds required to move a flare a distance
of more than 12" on smooth clean concrete pavement.
Both these tests help to predict the stability of
the flare if either bumped by a passing person or
vehicle or if used in a tempest of high wind and rain.
A) Result= 50º tilt required to topple the flare if
pushed from near its highest point to flat on it's
face
B) Result=Pointed at top/rear/ 80 PSI
Based on the forgoing we tentatively rate the Safety
Site 520 with base and carry case, a score of
5 Points
------------------
Durability
Long term and stress tests have not been
performed. First impressions are that in normal use
they are durable. The extra weight created by the
batteries and lack of a handle of any sort indicates
that care should be exercised in handling the Safety
Site flares in wet conditions as accidental droppage
is a possibility .Dropping the Safety Site on its
corner and face on concrete from 6' cracked the refractor
of one flare enough to render it accessible to water.
Based on our trials, we have provisionally given this
product a durability rating of:
4 points
------------------
Adaptability
The rear panel of the Safety Site has a brass
1/4X20 tread bushing for attachment to many possible
supports. An optional elevation ring adapter for mounting
on traffic cones or road triangles is available.
4.5 points
------------------
Pros > 1) Extremely effective alternative
to chemical based or incendiary flares 2) Economical
in the mid to long term. 3) Predicted to be stable
and resistant to toppling and flooding 4) Heavy-duty
build quality 5) Commercial grade but useful to consumers
6)Compact 7) Fit in standard traffic cones and may
be adapted with accessory kit 8) Hemispheric field
of visibility
Cons > 1) Slightly pricey for
consumers on a tight budget
2) Modality is a little awkward to
activate and change
Rating -4 Stars = Recommended
