What is “relevant” experience? Does my experience as _______ qualify?2020-04-10T22:26:07+00:00

Relevant experience is associated with a work practice that demonstrates the use of knowledge in the field. Experience that seems to be outside of the field may qualify if it relates or contributes to management of hazardous materials. For example, if one’s experience as a cost manager is applied to the management of a hazardous waste disposal site, it may qualify as relevant experience.

I did an internship in college. Will that count toward my experience requirement?2020-04-10T22:25:36+00:00

Maybe. It must have been valid work in a relevant field and it must NOT have been counted for credit toward your BS/BA degree.

What should I study for my certification exam?2020-05-05T22:27:41+00:00

Review the examination specifications table or ‘blueprint’ to determine the areas that may be covered in your examination. Each of the credential sections of the IHMM website includes a subsection on each credential’s “blueprint,” and that is an excellent place to start with preparing for your examination.

How do I reschedule my exam?2020-04-10T22:24:12+00:00

If I fail the test, can I take it again? How many times?2020-04-10T22:20:51+00:00

Yes. You may schedule to retake the test immediately after your official results email containing your score breakdown report. However, after a third failure, a candidate must wait a full year from the last attempt and submit a new application and pay full fees before trying again. He or she must also meet all the eligibility requirements then in effect.

Are fees refundable if, for some reason, I cannot take the exam?2020-04-10T22:20:13+00:00

The application fee is nonrefundable because of the time and effort that goes into processing the application. In order to reschedule at no charge, a candidate must do that at least 72 hours prior to their exam appointment. If you reschedule in less than 72 hours of your exam appointment, you must pay a $100 rescheduling fee.

When I pass the test, I’m certified, right?2020-04-10T22:19:47+00:00

Not yet. Passing the examination is a key element in becoming a CHMM, CHMP or CDGP. However, any IHMM issued certification only becomes official after all aspects of the application process are completed (online form, transcripts, third-party employment verification) and all fees are paid, allowing issuance of your numbered certificate.

I obtained a Certificate in Hazardous Materials Management from the University of California, so I am a CHMM, right?2020-04-10T22:18:40+00:00

No. “CHMM” is a trademarked designation for “Certified Hazardous Materials Manager.” Use of the designation by anyone who has not been certified by the Institute of Hazardous Materials Management (IHMM) is a violation of trademark law.
The hazardous materials programs offered by the University of California are similar to mini-degree programs, but they are strictly academic. They issue a certificate of completion, not a certification! The CHMM program combines academics and experience as prerequisites, and requires that you pass the national CHMM examination. That is the only way to become a CHMM.

Where can I prepare for a career in hazardous materials, dangerous goods, environment, health and safety?2020-04-25T00:07:54+00:00

IHMM has established the Hazardous Materials Society [HMS], found here >> https://hazmatsociety.org/   There, under the Education and Training page, you will find thousands of classes, courses, and webinars that can prepare you for your future. HMS has collected these courses from resources all over the communities of practice in which we operate and course offerings are updated and expanded each week.

Why should I consider certification?2020-04-10T22:13:34+00:00

Certification identifies individuals with the professional qualifications and expertise needed to handle, manage, and consult on matters relating to hazardous materials. Professional credentials serve as an independent validation of your proficiency in this interdisciplinary field.
Being certified can advance your career, enhance your employment status, and improve your chances of landing a better job. Employers understand that mishandling or mismanagement of hazardous materials can quickly become a critical element in the success or failure of a business. They depend on proven credentials like the CHMM, CHMP & CDGP to help identify those who are best qualified for the job.

What professional/ethical standards are IHMM’s certificants bound by?2020-05-01T18:56:05+00:00

Every IHMM certificant is bound by a Code of Ethics. Certification is granted only after the candidate pledges to abide by the Code of Ethics in their application. Suspected violations of the Code of Ethics are investigated by the IHMM’s Professional Standards Committee.  To report a violation of a Code of Ethics, return to your credential’s section of this website and look for Policies/Code of Ethics and you will find a Violation Form there.

What does a Certified Hazardous Materials Practitioner (CHMP) do?2020-04-10T21:12:26+00:00

The CHMP is a person experienced in handling hazardous materials in a wide variety of specialties, such as environmental protection, emergency response, safety, transportation, and security. CHMPs have experience in packing, shipping, tracking or securing hazardous articles; responding to spills; and/or cleaning up contaminated sites. The CHMP certification is related to the CHMM, but focuses more on hands-on or workplace experience as a practitioner and less on the management aspects of the field. The certification is designed for hazardous materials workers with at least 5 years of relevant experience but no BA/BS degree – or 3 years of relevant experience and an Associates degree in Applied Science (AAS).

What does a Certified Hazardous Materials Manager (CHMM) do?2020-04-10T21:07:38+00:00

A CHMM handles, manages, or advises others on hazardous materials or situations associated with or potentially including such items. A CHMM may perform management and/or compliance duties for a corporation, business, government, or some other organization in this capacity, or work in a related field associated with hazardous materials such as environmental protection, safety, hazmat transportation, or security. Any time hazardous materials are involved, a CHMM professional can advise on proper handling and management for ensuring safety and compliance.
