Safety vest with liners

The other half of safety vest development was the creation of a suitable base material, polyester, to bond with the fluorescence chemicals used. British chemists, John Rex Whinfield and James Tennant Dickson, patented polyethylene terephthalate (no, I can't pronounce it either). This became the basis of synthetic fibres like polyester, Dacron and Terylene.

Both Dupont and ICI contributed to the development of these materials in an unusual commercial alliance lasting 30 years between the 1920s and the 1950s which was part and parcel of the second wave of the Industrial revolution that witnessed the decline of heavy industries and the rise of consumer goods as factory products. As a result America left Europe behind in industrial strength and it could be argued the economic decline of Europe contributed to the 2nd World war.

According to Dupont, ' Plain polyethylene terephthalate(PET) is commonly associating with ...high performance clothing' ideal for the durability required of safety vests.

The history of safety vests is therefore a fascinating blend of ancient Oriental wisdom, modern physics and chemistry, social, economic and political history. Something to reflect on the next time you don one.

Each year devastating disasters ravage our nation, leaving behind countless victims. Pre-disaster planning can have a dramatic impact on minimizing the tragedy and suffering, resulting in a more efficient and coordinated (non panicked) response, and will save lives. Now is the time to prepare for these conditions. Do not wait until it is too late. And, do not be fooled into thinking that only other people are affected. Remember tornadoes, blizzards, floods, earthquakes, fires and biohazard material spills, can be due to a large number of different reasons, how well you plan, prepare and response to those situations will determine if you and your family will survive them.
