Be on alert Bleeding occurs in many ways. External bleeding is most commonly the result of cuts, abrasions and lacerations, but in severe cases may arise as the consequence of avulsions, puncture, impalement or amputation. A cut refers to a skin wound where the connective tissues have separated. There are “straight-line” wounds typically caused by sharp objects such as a knife, broken glass or sheet metal. Lacerations are differentiated from cuts by the nature of the wound. While both represent a separation of connective tissues of the skin, a laceration implies a torn or jagged wound usually brought about by blunt-force trauma (i.e. collisions, falls, etc.). In severe cases, the term gash may be used as it implies a significant cut or laceration. Avulsions, considered to be the most dangerous class of external bleeding injuries, are wounds where connective tissue is torn away from the body. This includes skin flaps (minor), degloving (moderate to severe) and amputation (serious to life-threatening). The range of severity is broad for injuries resulting in external bleeding. From those requiring no medical attention to incidents requiring it immediately, first responders need to evaluate what type of bleeding injury has occurred. While gashes, degloving and amputation injuries are self-evident in their need for medical assistance, less severe bleeding may not be. If any questions exist as to the severity of an injury, always err on the side of caution. Unless you are sure medical treatment isn’t necessary, be prepared to dial 911. Let’s say a coworker of yours has badly cut his calf on a piece of sheet metal that slipped out of his hands. The wound is seeping blood and it’s unclear how deep the injury is. Another employee witnessed the incident and ran off in search of a first-aid kit. You’re standing there alone with the victim. He is lucid but in considerable pain. What do you do? If you’re first instinct is to put pressure on the wound, you are correct. But do you have gloves? Gloves are integral in assisting the victim with bleeding conditions. Environments with a chance for contact with blood represent a heightened risk of pathogens. OSHA Standard 1910.1030 focuses on bloodborne pathogens and how to respond to incidents involving the risk of exposure. To learn more about bloodborne pathogens, PPE and blood-stained waste disposal, go to www.osha/gov. If you do not have gloves with you, the best protocol to follow is having the victim put direct pressure on the wound until you’ve obtained them from your first-aid kit. Tip: Most first-aid kits have latex or non-latex gloves in them. If yours doesn’t, consider upgrading your kit to one that does. Once you have gloves, put them on. If you don’t have any available, improvise a barrier to limit the potential for contact with the victim’s blood. The next step is to place a sterile dressing or clean cloth on the wound. Apply direct pressure with your hand for about 5 minutes. Tip: Do not put pressure on the area if you know there is an object embedded in the wound. If this scenario involved a head injury, you would avoid putting pressure on the scalp in case the victim’s skull was injured in the incident. Following this procedure, the first responder must reevaluate the bleeding condition. If it persists, put another dressing or cloth pad on top of the first one and keep applying pressure. If needed, apply a pressure bandage to keep pressure on the wound, wrapping from the end of the extremity toward the center of the body. Tip: The pressure of the bandage should be snug but loose enough to slip a finger under it. Learn more about applying pressure bandages in the Toolbox Talk at www.asa. net/safety. While you are treating the wound, make regular checks on the victim’s condition. If the victim is unconscious or suffering from shock, call 911. In the event of any extreme injury (i.e. amputation, degloving, severe gashes, etc.), a first responder may wrongfully consider the use of a tourniquet. Be advised tourniquets are a measure of last resort and should only be used by certified rescue trainers. There is a high risk of complications in the procedure and it should be avoided by anyone not specifically trained to perform it. Measures to control bleeding, apply pressure bandages and dress wounds are only part of the knowledge a first responder needs. It is equally important to understand how to clean a wound, how to identify the signs and symptoms of infection or internal bleeding, and to recognize when medical attention is needed.
