In the 1990’s, 3M Canada introduced the concept of a yellow/silver/yellow trim on flame resistant (FR) coveralls. This FR trim served a dual purpose, the yellow offered enhanced daytime visibility and the retroreflective silver served for dusk, low light, and dark conditions. The yellow/silver/yellow trim used at the time was 9587, a trim that was FR and designed for the fireman bunker gear. Soon this yellow/silver/yellow solution became the norm, but there was a significant challenge with it as it could not withstand industrial washing for the Oil & Gas and Utilities market, which heavily soiled garments needed, to be cleaned.
