(a) In institutions equipped to render laundry service, duty laundry shall be done without charge for all officers and employees.

(b) Except as provided in subdivision (d) of this section for certain resident medical and dental officers, resident officers and employees in such institutions shall also have personal and household laundry done without charge, unless there are family members residing with them. If there are family members residing with them, no personal or household laundry shall be done unless a payroll deduction of $2.50 per month is made for each family member other than such officer or employee.

(c) If the visit of nonofficial guests extends to one month or longer, the host officer shall be charged for his guests' laundry, according to schedule.

(d) Resident medical and dental officers now or hereafter subject to the 1967 medical salary plan shall be ineligible for personal and household laundry services for themselves and their families. Such officers shall continue to have their duty laundry done without charge at institutions equipped to render laundry service. Duty laundry shall consist of uniforms or special apparel prescribed and required by the agency, but excludes articles which are adaptable to general or continued usage so as to take the place of ordinary clothing, such as men's dress shirts. Where commercial laundry services are not available as determined by the head of the agency, the State shall make available coin-operated, self-service laundry equipment at such institutions or facilities for the use of such officers and their families.
