Mustang Survival is notifying the public of an "urgent advisory" for hydrostatic inflatable PFDs made during April and May. A portion of these PFDs could be subject to delayed or non-inflations, according to the manufacturer.

Consumers are instructed to check the carbon dioxide cylinder in their vest. If it is marked with LOT No. 404121 or 404122, they are urged to contact customer service at (800) 526-0532 for further instructions and to arrange for a replacement inflator assembly.
