Commercial kitchens can be quite dangerous at times. The odds of employees getting cut, burned, punctured or hit are generally pretty high. It is important to have first aid supplies on hand and in an easily accessible area for such occasions. Kitchens are not the only place injuries occur. You might want to assess your business for dangerous possibilities and then provide first aid kits for use.
Don't take any chances not having the supplies you need to stop someone from bleeding or hurting after an injury. Workman's comp is not fun for anyone, so the more you can help treat an injury as soon as it happens, the easier dealing with the claim can be.
