If you're really starting from scratch, look into an OSHA 30 hour course for general industry. Don't do one of the online, self-directed programs as you won't actually learn anything. I did one through Zoom because COVID, and it was helpful, but an in-person class would be better.
Establish an Injury and Illness Prevention Program, Hazard Communication Program, and Lock Out/Tag Out training program. There are lots of resources on OSHA's website for this. Don't re-invent the wheel, just use one of their templates.
Make sure that you are tracking all injuries and illnesses properly (OSHA 300, 300A). You'll probably work with HR on this.
Next, I would suggest creating internal audits that are specific to occupational safety. Without knowing the nature of your business I'm not sure what your hazards are, but general items to check are:
- Are emergency exits blocked?
- Have all fire extinguishers been checked and signed off monthly, and recharged yearly?
- Is all machine guarding in place?
- Have all employees received training on equipment (including forklifts)?
OSHA has some industry-specific resources here, that may or may not be helpful: https://www.osha.gov...stance/industry
Next, just google for "Top 10 OSHA Citations", "OSHA Food Manufacturing", etc and read what comes up. Most of what I've learned has been self taught.
Happy to answer any additional questions. Also, let us know what industry you're in, as hazards are different in different industries.
