An armband is a band of material worn around the upper arm over the sleeve of other clothing if present. In a safety context armbands are worn to mark the wearer as belonging to group, having a certain rank or role, or being in a particular condition or state. So for example trainee employees may wear them to denote special care to be taken or first aiders to denote special competency. At The Safety Supply Company we manufacture dozens of arm bands which are kept in stock for speedy delivery.
