Except for transportation by aircraft or as otherwise provided in 49 CFR 172.315, a package containing a limited quantity of hazardous materials is not required to be marked with the proper shipping name provided it is marked with the biohazard warning symbol and biohazard legend within a square-on-point border. Available with a preprinted biohazard legend and warning symbol, these durable and removable PVC-free vinyl markings measure 273 x 273mm and are sold in packs of 25 as well as cases of 900.
