When you are driving down the highway, and you see construction workers, rescue workers, or persons picking up litter along the roads, have you noticed the bright colors they wear?  Those vests, hardhats, clothing with reflective stripes, etc. are there for their protection, to assure that they are conspicuous to oncoming traffic.

When you watch emergency personnel doing their job, notice those bright colors on their clothing, and remember that is just one of the many ways to help ensure their safety.

Primary Safety Colors are:

• Safety Orange – Used for vests, traffic cones, hunting vests, barrels and other construction marking devices.

• Fire Engine Red – Named mainly for fire engines and other emergency vehicles.

• Chartreuse Yellow – Greater visibility at night; many cities now use this color for fire engines and emergency equipment.

• Neon Yellow – Most visible color to the human eye, present on most vests.

• High Visibility Yellow – Used for coveralls, rainwear, slush boots.

There are all types of safety wear, from reflective strips for hardhats, reflective gear for firemen, police, emergency responders, vests with various color stripes, to full body protection.  There are high visibility hardhat covers, hi-vis gloves, GloMega Glow in the Dark hardhats.  For work or travel, consider Pack and Pop cones with lights, Safety Flags (orange), and Safety Kits for Motorists, which have an orange and white triangle, reflective vest, and road flares.  Bikers, motorcyclists, and evening walkers need to have some sort of reflective gear (vests, stripes, etc.) to make motorists aware of their presence.
