One little tip, if you don't like the white rubber talc for the gloves, try some industrial latex gloves (look like the ones the doctor uses but not sterile)...I have a box in black and one in blue.
Also, be careful what you clean your gloves with, some things will make the rubber brittle and crack easily.
Check your gloves by rolling them up like Trumpy said, if youput the talc in first, you can see the smaller holes on the dark of the glove even easier.
Our company requires us to complete a form that states we checked our gloves everyday and lists the gloves by serial number.
My mind just went blank about the 70E requirement for testing, but I know we change gloves every six months and send them in for testing.
