That's the problem with 'central planning' and 'one size fits all' solutions.
ID Badges ..... lanyards .... just more crap to get caught in a machine. Under the clothing? Well, it is considerate that we make it easier to identify the body.
I want to remind readers of some of the discussions we've had here, about wearing the hard hat 'backwards.' I want to underscore thepoint that, IMO, we're no longer talking about safety, or safety management.
No, we're talking about a totalitarian management ethos that just wants to make rules to show off their power.
We're talking about fashion, and costumes - not PPE.
Good heavens ... as I type this I am wearing the REQUIRED FR uniform, reflective vest, hard hat, safety glasses, ear muffs, and safety boots with metatarsal guards. Heaven forbid I strip down to just a cotton t-shirt in this 98 degree / 76% humidity environment. Heaven forbid that I put a sticker on my hard hat - or that I fail to wear the two 'safety' tags they gave me to wear.
("Safety tags" are credit-card size laminated bits of propoganda, filled with small print telling me things like "work safely.")
Now, folks might come up with all manner of wonderful explanations as to 'why it must be so.' They might even be right- but whatever it's about, it isn't safety. It might be convenient for folks to see, from a block away, that you belong there- but that convenience has a trade-off against safety.
BTW ... anyone ever pause to wonder about the effect bug spray has on FR ratings?
Another point about FR clothing, and other PPE: It is ALWAYS ridiculed when someone brings up the obvious fact that adding clothing introduces other risk factors. At this particular place, that includes the coming, seasonal, heat-stress injuries. "Comfort" may sound like something sissies complain about, but the simple fact is that when you're uncomfortable you're distracted and your judgement suffers. Do you really want to be swatting mosquitos while you're working hot?
