I presume that you are referring to OSHA First Aid Case criteria that are typically used by most Oil & Gas/ Downstream majors?
OSHA First Aid Case criteria are prescriptive, refer to the link below, and scroll down until you come to the question, "What is "first aid"? " :-
https://www.osha.gov/pls...=STANDARDS&p_id=9638What is "first aid"? For the purposes of Part 1904, "first aid" means the following:
#Using a non-prescription medication at nonprescription strength (for medications available in both prescription and non-prescription form, a recommendation by a physician or other licensed health care professional to use a non-prescription medication at prescription strength is considered medical treatment for recordkeeping purposes);
#Administering tetanus immunizations (other immunizations, such as Hepatitis B vaccine or rabies vaccine, are considered medical treatment);
#Cleaning, flushing or soaking wounds on the surface of the skin;
#Using wound coverings such as bandages, Band-Aids™, gauze pads, etc.; or using butterfly bandages or Steri-Strips™ (other wound closing devices such as sutures, staples, etc., are considered medical treatment);
#Using hot or cold therapy;
#Using any non-rigid means of support, such as elastic bandages, wraps, non-rigid back belts, etc. (devices with rigid stays or other systems designed to immobilize parts of the body are considered medical treatment for recordkeeping purposes);
#Using temporary immobilization devices while transporting an accident victim (e.g., splints, slings, neck collars, back boards, etc.).
#Drilling of a fingernail or toenail to relieve pressure, or draining fluid from a blister;
#Using eye patches;

Are any other procedures included in first aid?
No, this is a complete list of all treatments considered first aid for Part 1904 purposes.
Does the professional status of the person providing the treatment have any effect on what is considered first aid or medical treatment?
No, OSHA considers the treatments listed in § 1904.7(b)(5)(ii) of this Part to be first aid regardless of the professional status of the person providing the treatment. Even when these treatments are provided by a physician or other licensed health care professional, they are considered first aid for the purposes of Part 1904. Similarly, OSHA considers treatment beyond first aid to be medical treatment even when it is provided by someone other than a physician or other licensed health care professional.
