The IHMM (Institute of Hazardous Materials Management) is currently working on protecting the credentials of the CHMM and others (CSP, CIH etc). They are targeting legislatures in Wisconsin and Florida. The Wisconsin bill was read on March 28, 2017 for the first time. 

This bill prohibits a person from using the title of certified dangerous goods professional, certified hazardous materials manager, certified hazardous materials practitioner, certified health physicist, certified industrial hygienist, certified safety professional, or registered radiation protection technologist, or the initials for these titles, unless the person is certified or registered to use that title by the Institute of Hazardous Materials Management, the American Board of Health Physics, the American Board of Industrial Hygiene, the Board of Certified Safety Professionals, or the National Registry of Radiation Protection Technologists.

The bill also prohibits a business from representing that the services that the business provides are furnished by one of these certified or registered professionals unless those services are provided by, or are provided under the direct supervision of, a person who is permitted to use that title under this bill. Under the bill, a person is also prohibited from misleading or deceiving another person by the unauthorized use of a certification mark awarded by the U.S. Patent and Trademark Office that includes one of these titles. 

Under the bill, a person who violates these prohibitions is guilty of a misdemeanor and may be fined not more than $1,000. The bill also provides that a violation of these prohibitions is an unfair method of competition in business or an unfair trade practice, and allows a person who suffers a monetary loss because of a violation to sue for twice the amount of the monetary loss and reasonable attorney fees. The bill also allows the Department of Agriculture, Trade and Consumer Protection to bring a court action for an injunction to restrain a violation of these prohibitions. In addition, this bill prohibits a city, village, town, or county from enacting an ordinance or adopting a resolution that restricts the use of these professional titles.

If you support this bill, please call or email your Assembly Representative or State Senator in support.  Last year, a similar effort failed to get past the Wisconsin Senate (did not get out of committee.) The more voices the better.
