how do i break into the industrial hygienist industry in ontario?

What cert do I need to do?
How do i get those ethics courses for the CIH?

Do i need an accredited degree for this? i’m in uoft and they don’t have any accredited IH undergrad degrees.

i’m already halfway through my studies and i missed the application deadline for TMU’s occupational health and safety degree.

can i get into this industry with just a bachelors, or is a postgrad degree necessary?

bachelors:
double majors in
chemistry
environment and health

tysm!

Engineering vs IH, former engineers how did you know it was for you?

I am an engineering student but my last internship was in IH. I enjoyed learning about it, but am very conflicted on which I want to pursue.

On one hand, I like learning about everything and found IH interesting in that regard. On the other hand, I am worried on whether I could do this for my career as I heard pursuing IH would make it hard to switch to engineering jobs. I don’t enjoy safety either but I really liked IH topics, but I’m worried that I might be making the choice based on that I like to learn about everything. Engineering wise, I was never interested in my classes but I’m good at it.

Any engineers here that chose IH? How did you decide?

Asbestos and HEPA filter

I’m trying to understand a specific asbestos/HEPA-filter scenario and would appreciate input from people familiar with filtration or asbestos exposure. I used a Levoit Core 400S for roughly two months after it had previously been used in an renovation environment where asbestos-containing material have been disturbed. (didn't know at that moment about content)

My concern is that if asbestos fibers were captured by the filter, could some of those fibers later detach or become re-entrained during normal operation, changes in airflow, low-level vibration, or handling of the purifier? I’ve come across studies reporting re-entrainment from loaded HEPA filters, but the experimental conditions seem to vary considerably.

I’m particularly interested in whether those studies are realistically applicable to a household HEPA purifier operating under normal conditions, and whether fibers that were previously trapped in the filter could realistically produce a meaningful airborne concentration in the room, and if so, what levels could be?

Should we test our air for formaldehyde?

We have been finding bits of what appear to be fiberglass ductwork on our floors. That's a whole separate issue, but we will probably be calling in HVAC to look around.

We live in a rental home built in 1957. The home has pink fiberglass insulation. In my reading about what these weird bits could be, I discovered that old fiberglass insulation contains formaldehyde which is not typically a danger unless heated or subject to humidity, then it off-gasses. It gets extremely hot in our attic here, we live in GA. We can literally feel and smell the hot air standing under vents/the attic hatch. The attic is at least somewhat ventilated. We had a leak awhile back above our laundry room which was fixed but who knows what remains up there. We have an infant in the home and it has never occurred to me that formaldehyde could be getting into the house. We are only here for 5 more months.​ I doubt the landlord would agree to pay for this (or the HVAC), but we are prepared to if need be. Just concerned about our little one and pets with the cancer risk.

Is this a concern or am I overthinking it? if so, are there any reliable tests I can do myself?

New Grad considering IH but have a few concerns

Hey all! I am a recent grad with an B.S. in the environmental sciences and realized a lot of my interests align with human health, biological sciences, and helping people. I am considering doing a masters in IH, especially with the funding out there for ERCs.

However, family and friends have stated concerns about the field being over saturated with technicians w/o degrees limiting earning potential with a Masters, the salary outlook, higher earning roles being taken by Senior Engineers, and the field being “rough for a lady”.

Any insight on the above ideas would be deeply helpful, thanks!

Unsure if I accidentally made carcinogenic hexavalent chromium by repeatedly applying bleach to stainless steel?

I have been applying a 2-3% bleach spray regularly to a stainless steel refrigerator door for disinfection every 1-2 days for the last 2-3 months and have noticed that there are areas of corrosion forming on the refrigerator door (I was not aware that you are not recommended to apply bleach to stainless steel, so please forgive my ignorance). I recently also noticed there is a powder forming below the refrigerator door from the bleach spray runoff, and that the powder has a slight yellowish tint.

I just learned that stainless steel contains the metal chromium, and that while the chemical form of chromium in stainless steel is harmless, there also exists a form called hexavalent chromium, which is carcinogenic. According to a webpage from the British Stainless Steel Association stating "There is one very specific example where corrosion [of stainless steel] may produce very small quantities of hexavalent chromium at ambient temperature. This is where some strong oxidisers with a pH of 10-14 are in prolonged contact with stainless steel and cause corrosion over time."

Given that bleach is an oxidizer, I am worried about whether these repeated bleach applications could have oxidized the stainless steel door enough to produce a significant amount of hexavalent chromium (which can be yellow, such as in the compound sodium chromate). In a situation like this, how likely is it that there is a harmful amount of hexavalent chromium produced from multiple dilute bleach applications to stainless steel?

Recent ecology grad wanting to do industrial hygiene

I am a recent grad with an ecology degree looking at environmental consulting and i am interested in getting a entry level position as an IH technician. I have worked doing over 2 years of field work in my undergrad lab doing water quality monitoring, technical writing, and i am trying to get advice on how to pitch my skills and background considering I dont have a degree in something IH related. I am meeting with a consultant who works in IH for an informational interview, but I thought i could ask here as well. Im in the Midwest btw

Which Tests For Unknown Particle Identification?

I have a new, grainy dust that formed uniformly over my apartment during demo work on the exterior of my apartment building. The demo work involved pulverizing stucco. The grainy dust does not appear in my walk-in closet, which I frequently use.

I've been told that a certified industrial hygienist could help with unknown particle identification. What type of testing should I be asking for?

My understanding is I would want to take samples from affected and unaffected rooms to get a relative comparison

  • Stereomicroscopy for sorting out particle type
  • SEM-EDX for elemental composition
  • XRD for mineral component identification
  • (micro-)FTIR because paint is suspected
  • Some type of petrographic analysis in addition to the chemical analysis

Am I missing something or on the wrong track?

Science degree working in safety, want to work in IH

Love the field. IH is what I imagined scientists did as a kid. I love keeping people safe, and while I do a lot of that at my current job as a ehs specialist, I’d like to get the best cert in the game but feel like its out of reach due to not having a engineering degree, and having only a 3.3 gpa for my unfergrad

If anyone has advice, I’d love to hear it

Is it possible for me to get an entry job? How to break into the field?

I will graduate soon and have an offer for an MPH at my school, where ideally, I’d like to do my MPH online while working full time, is this doable?

What other experiences should I am to get?

I have an engineering degree and the only IH related experience is a 6 month internship at a large pharma company as an EHS intern where I helped with a lot of IH tasks such as sampling.

Should I be applying for EHS jobs as well? I don’t want to be stuck in safety though.

Construction safety to CIH.

Just thought I’d share a bit of my journey. bachelors in geology kinda fell into safety on accident but I love it. Work in civil qa at the moment with larger than normal safety responsibilities. Just passed my chst and planning to shift to a safety specialist role at the same company after my paternity leave.

I expressed interest in getting my cih and getting more involved with atmosphere testing in confined spaces, and my company agreed to let me take part in this work. It is my opinion that construction safety will move into a mandatory csp for all manager roles and for higher paying jobs (director, regional) cih will be heavily sought after.

Is this a common line of thought? Anybody else in the construction or utility safety worlds done this before?
