WoundSeal is a topical powder that stops bleeding by forming an instant scab. WoundSeal is a first aid treatment for cuts, lacerations, and other external bleeding. After applying powder and light pressure for about 30 seconds, the scab forms to seal and protect the wound and then falls off naturally as the wound heals. WoundSeal is a wound covering (not a closure), and is not OSHA recordable; Hemostatic agents like WoundSeal are now recommended in the latest 2014 ANSI standards. WoundSeal is hypoallergenic and safe for all ages.
