Getting started in ESH/industrial hygiene?

Hey all! I'm attempting to undergo a somewhat major career change from public health to environmental health and safety and/or industrial hygiene. I'm having a tough time finding jobs that don't require years of experience, though, even entry level positions seem to want 1-2 years of experience or certifications (CSP/ASP) that require experience.

Anyone have any advice on how to break into this field? Here are my qualifications, for reference:

BSc Biology

MSc microbiology

OHST (Occupational Hygiene and Safety Technician)

OSHA 30 hour general industry training

HAZWOPER 40 hour
