These Biohazard Labels include the universally recognized biohazard symbol. Biohazard warning labels meet OSHA's marking requirement in 29 CFR part 1910.1030 for bloodborne pathogens. OSHA requires that biohazard markings shall be affixed to containers of regulated waste, refrigerators and freezers containing blood, and other containers used to store, transport or ship blood or other potentially infectious materials. These fluorescent orange/red Biohazard Labels are an easy way to meet OSHA requirements. Warning Labels measure 1" x 1", 2" x 2", 4" x 4" and 6" x 6" and are sold in rolls of 500 paper labels. Style H-BBLRS is a 4" x 4" label with the warning printed in both English and Spanish.
