It is extremely important for all employees on a worksite to understand the basics of first aid. Contractors work in a wide variety of dangerous conditions, and they constantly face the risk of falls, struck by/caught between accidents, cuts, burns, and other injuries (depending on the industry and specific task being performed). If each employee understands the basics of first aid, this results in a safer environment for all involved. Minor injuries can be treated quickly to prevent infection or further strain. Additionally, trained employees can recognize the signs of more serious injuries, and therefore the appropriate aid can be called as soon as possible.
