Except in the case of a worker whose exposure to lead is only recent, renal disease should always be indicated by a numeral.
Letters should bear the following meaning:
A. No comment (i.e., fair general health).
B., C. Increasing degrees of impairment of general health. (Pregnancy, if without suspension, should be entered as C.)
D. Suspension or transfer, for reasons other than impairment of health from effects of work in lead.
X. Carelessness, or neglect of precautions, or unsuitability for work in lead. (Suspensions for such reasons should be marked DX.)
Such entries of numerals and letters will in general suffice for the intended purpose; but the surgeon may, of course, find it desirable to make other notes for his own information, and it is within his discretion to supply further details to occupiers or workers concerned.
