This box of 20 assorted blue detectable plasters is ideal for replenishing a catering first aid kit, in particular one of our Fast check or deluxe catering first aid kit. Our range of blue detectable plasters are supplied with an aluminium sheet under the wound pad that can be detected by a metal detector making them ideal for employees working in the food processing & handling areas. They protect against cross contamination between blood & the products handled, whilst providing a visually detectable product due to its blue colour should the plaster become loose. All our blue detectable plasters are tested according to ISO 10993 & are hypoallergenic, non cytotoxic & latex free.
