For anyone that is interested this is the definition of the Standard of Care from the Black's Law Dictionary. It appears to me the Standard of Care is more of a consept as considered by the Law, It does not address a specific document or set of documents but more relies on the person's actions in relationship to the actions of others within the same profession.

The standard of care is the degree of care that a reasonably prudent person would exercise in the circumstance in question. In negligence law if a person's conduct falls below such standards, he may be liable in damages for injuries or damages resulting from his conduct. In professional malpractice cases, a standard of care is applied to measure the competence as well of the degree of care shown by the professional's actions. A traditional standard for a practitioner is to "exercise the average degree of skill, care, and diligence exercised by members of the same profession (or specialty within that profession), practicing in the same or a similar locality in light of the present state of the profession.

It is well documented that the medical profession has multiple standards of care for the treatment of a disease. Could not the fire investigation profession also have multiple standards of care?
