Workplace first aid procedures depend on the patient and their suffering. When it comes to a heart attack, the first thing to do is ensure that they sit down. Call the emergency number right away, but try to determine if they suffer from a heart attack or a different issue. Heart attacks bring in persistent chest pains that spread to other parts of the body. The patient must relax, whether they lay down on the floor or lean against a chair. Keep them conscious and reassure them that everything will be alright if they breathe deeply while trying to relax.
