Respirator Fit Test Demonstration 

@Beckham Darren thanks

"Victim" haha

If you know this then you have to the right to report it. If you don't and something happens you are also reliable

@@angelsaldana4821 Construction is a joke when it comes to safety. No one is going to risk a lay off. No one will say anything.

The video shows what they are around the 1:10 mark or so. One is an artificial sweetener and the other is one that has a bitter taste. The most bitter taste known to man. It's Denatonium Benzoate, otherwise known as Bitrex. It's often put into household, garden and automotive products to ensure that if a child or animal ever tried to swallow it, they would spit it straight out before they could be poisoned. Both are completely harmless.

Brian Knab thanks for the response

@@brianknab8367 i think it’s in isopropyl alcohol as well 😂

So they can breathe better

I dont think so , one or two you stil ganna breath Co2

kyo adam it dose because if you block the other valve you only have one way to breath or for example you are in a area with lots of dust the second one gives extra protection.

@@kyoadam1593 There is a one-way exhaust valve when you exhale with these masks. Air only moves through the filter on inhalation. Two cartridges balances better on your face.

Where do I ask them?
