Our self sealing biohazard bags are made from a yellow polyethene plastic & have the words Biohazard & dispose safely by incineration on them. They also contain the internationally recognised biohazard symbol on each bag & are used to safely dispose of any materials that may have bodily fluids on them such as vomit, blood, urine. This is the largest sized biohazard bag in our range & measures 420x 630mm & comes in a pack of 100 individual bags. In addition any soiled material such as gloves, aprons etc. should also be placed in these bags & incinerated to prevent any cross contamination & disposable should be via pre-determined means.
