First aid includes any one-time treatment and follow-up for observation of minor injuries, including cuts, abrasions, bruises, first-degree burns, sprains, and splinters. Injuries or illnesses requiring only first aid are commonplace. One or more workers should be properly trained to administer basic first aid, including CPR. Workplaces should have a well-stocked first-aid kit and at least one or more employee assigned the responsibility for administering or coordinating first-aid treatments.
