     AN ACT Relating to the use of dental restorative materials containing mercury in the practice of dentistry; adding new sections to chapter 18.32 RCW; and providing an effective date.

BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF WASHINGTON:

NEW SECTION.  Sec. 1   A new section is added to chapter 18.32 RCW to read as follows:
     (1) A dentist shall obtain a written informed consent from each patient prior to any dental procedure or treatment that includes the use of dental restorative materials that contain mercury. The written informed consent form must be substantially in the following form in at least twelve-point type:

     "INFORMED CONSENT FOR DENTAL MATERIALS CONTAINING MERCURY

Patient's name:

Date of procedure and/or treatment:

Dentist's name performing procedure and/or treatment:

Brand name, trade name, and commonly used name of dental material containing mercury:

Lot # of product:


NOTICE: The above-identified dental material contains mercury. The United States government has published the following facts about mercury:

1. Mercury vapor is released from dental materials containing mercury which is the number one source of mercury in the human body. (World Health Organization, Document No. 118 (1991).)

2. The human nervous system is very sensitive to all forms of mercury.

3. Metal vapors are more harmful than other forms of mercury, because more mercury in this form reaches the brain.

4. Exposure to mercury can permanently damage the brain, kidneys, and developing fetus.

5. The effects of mercury on brain function may include irritability, shyness, tremors, changes in vision or hearing, and memory problems.

6. Short-term exposure to high levels of metallic mercury vapors may cause effects including lung damage, nausea, vomiting, diarrhea, increases in blood pressure or heart rate, skin rashes, and eye irritation.

7. Fetuses and very young children are more sensitive to mercury than adults. Mercury in the mother's body passes into the fetus and can pass to a nursing infant through breast milk.

8. The harmful effects of mercury that may be passed from the mother to the developing fetus include brain damage, mental retardation, incoordination, blindness, seizures, and an inability to speak. Children poisoned by mercury may develop problems of their nervous and digestive systems and kidney damage.

The description of the effects of mercury set out in facts 2-8 above is excerpted from the United States Agency for Toxic Substances and Disease Registry (ATSDR), 1999, Toxicological Profile for Mercury. Atlanta, GA: U.S. Department of Health and Human Services, Public Health Service. The complete profile is found at:

Patient acknowledgment:
     My signature below means that I have read and understood this description of the effects of mercury as set out in this informed consent form. I consent to the use of the above-listed dental material containing mercury and release my dentist from any liability for harm to me from the identified dental filling material. I have also been provided with a signed copy of this form to take home with me.

Patient's signature or guardian's signature:

If patient is a minor or incapacitated, name of patient:

Treating dentist's signature:

     (2) A copy of the signed informed consent form must be provided to the patient. The original signed informed consent form must be placed in the dental chart of the patient for as long as the dentist retains the dental chart for the patient.

NEW SECTION.  Sec. 2   A new section is added to chapter 18.32 RCW to read as follows:
     Any dentist who removes dental restorative materials containing mercury from a patient's teeth shall disclose the health risks of removal.

NEW SECTION.  Sec. 3   A new section is added to chapter 18.32 RCW to read as follows:
     (1) There may be no disciplinary action against a dentist who:

     (b) Removes or places any professionally recognized restorative dental material with the informed consent of the patient; or
     (c) Fails to conform to policies or codes of private organizations that are inconsistent with state law.
     (2) Nothing in this section may be construed to allow a dentist to defraud a patient.

NEW SECTION.  Sec. 4   A new section is added to chapter 18.32 RCW to read as follows:
     (1) Every dental office that uses dental restorative materials containing mercury or removes these materials from the teeth of patients must install mercury separators on any wastewater drain through which mercury containing materials pass. The mercury separator must be certified by its manufacturer utilizing the best available technology.
     (2) Dental materials containing mercury, whether restorative materials removed from patients' teeth or excess material from new restorations, must be placed in a vapor-proof container clearly labeled as containing mercury and must be treated as hazardous waste and disposed of in accordance with federal and state law. The material may not be placed in biohazard bags intended for incineration.

NEW SECTION.  Sec. 5   A new section is added to chapter 18.32 RCW to read as follows:
