Oregon Administrative Rules › Chapter 437 - DEPARTMENT OF CONSUMER AND BUSINESS SERVICES, OREGON OCCUPATIONAL SAFETY AND HEALTH DIVISION › Division 2 - GENERAL OCCUPATIONAL SAFETY AND HEALTH RULES › Section 437-002-0391 - Additional Oregon Rules for Carcinogens in Laboratories

Current through Register Vol. 63, No. 7, July 1, 2024
(1) Definitions.
"Absolute filter" is one capable of retaining 99.97 percent of
				a monodisperse aerosol of 0.3 µm particles.
For the purposes of OAR
				437-002-0391,
				"carcinogen" is defined as the substances regulated by  29 CFR 1910.1003, 1910.1004, 1910.1006, 1910.1007, 1910.1008, 1910.1009, 1910.1010, 1910.1011, 1910.1012, 1910.1013, 1910.1014, 1910.1015, 1910.1016  and OAR
				437-002-0364.
(2) Laboratory activities.
			 The requirements of this section shall apply to research and quality control
			 activities involving the use of a carcinogen.
(a) Mechanical pipetting aids shall be used
			 for all pipetting procedures.
(b)
			 Experiments, procedures and equipment which could produce aerosols shall be
			 confined to laboratory-type hoods or glove boxes.
(c) Surfaces on which a carcinogen is handled
			 shall be protected from contamination.
(d) Contaminated wastes and animal carcasses
			 shall be collected in impervious containers which are closed and decontaminated
			 prior to removal from the work area. Such wastes and carcasses shall be
			 incinerated in such a manner that no carcinogenic products are released.
(e) All other forms of a
			 carcinogen shall be inactivated prior to disposal.
(f) Laboratory vacuum systems shall be
			 protected with disposable absolute filters. Exhaust systems containing such
			 filters shall be provided with suitable ports or openings to enable
			 determination of whether the filter in its operating location, does meet the
			 efficiency requirements defined in OAR
			 437-002-0391(1).
			 Determination of filter efficiency shall be by measurement, with a forward
			 light scattering photometer, of passage of a polydisperse dioctyl phthalate
			 aerosol.
(g) Employees engaged in
			 animal support activities shall be:
(A)
			 Provided with, and required to wear, a complete protective clothing change,
			 clean each day, including coveralls or pants and shirt, foot covers, head
			 covers, gloves, and appropriate respiratory protective equipment or devices;
			 and
(B) Required to remove and
			 leave protective clothing and equipment at the point of exit prior to each exit
			 from a regulated area and at the last exit of the day, to place used clothing
			 and equipment in impervious containers at the point of exit for purposes of
			 decontamination or disposal. The contents of such impervious containers must
			 display the following warning:
DANGER
CONTAMINATED
MAY CAUSE CANCER
(C) Required to wash hands, forearms, face
			 and neck upon each exit from the regulated area close to the point of exit, and
			 before engaging in other activities; and
(D) Required to shower after the last exit of
			 the day.
(h) Employees,
			 other than those engaged only in animal support activities, each day shall be:
(A) Provided with and required to wear a
			 clean change of appropriate laboratory clothing, such as a solid front gown,
			 surgical scrub suit, or full buttoned laboratory coat.
(B) Required to remove and leave protective
			 clothing and equipment at the point of exit prior to each exit from a regulated
			 area and at the last exit of the day, to place used clothing and equipment in
			 impervious containers at the point of exit for purposes of decontamination or
			 disposal. The contents of such impervious containers must display the following
			 warning:
DANGER
CONTAMINATED
MAY CAUSE CANCER
(C) Required to wash hands, forearms, face
			 and neck upon each exit from the regulated area close to the point of exit, and
			 before engaging in other activities.
(i) Air pressure in laboratory areas and
			 animal rooms where a carcinogen is handled and bio- assay studies are performed
			 shall be negative in relation to the pressure in surrounding areas. Exhaust air
			 shall not be discharged to regulated areas, non-regulated areas or the external
			 environment unless decontaminated.
(j) There shall be no connection between
			 regulated areas and any other areas through the ventilation system.
(k) A current inventory of carcinogens shall
			 be maintained.
(l) Ventilated
			 apparatus such as laboratory type hoods, shall be tested at least semi-annually
			 or immediately after ventilation modification or maintenance operations, by
			 personnel fully qualified to certify correct containment and operation.
