If I’m looking at this question correctly, whomever is asking it is more than likely wanting to know if it’s a good idea to start an OSHA training company and if it would be profitable? Not how big the course offering market is for OSHA training, which is what I think some of the answers I’ve seen on here are really answering. Good info, but I’m reading the original question differently.If I’m right, I’m going to say it’s expensive and you have to be willing to take on a lot of liability. This isn’t to deter you from pursuing it, but many people think, “well dang, I’m paying $400 bucks for this guy to go through a slide show on how not to be an idiot on my job and not get hurt and there’s 15 people in this class, that’s $6000 for a few hours of work! Pssh…I can do that!” Right, what they are failing to realize is that as a safety professional, especially, anyone who is training anyone or organization, that person assumes liability for the training they have provided. I’ll give you a personal example.We did a job for the U.S. Army Corps of Engineers that took nearly 1.5 years to complete. (If you’re not familiar with working with the Army Corps. of Engineers, I can tell you that you better know your s**t and you better have the credentials to back up your training program. If you don’t they will shut you down faster than you can say OSHA and you will be removed from the job.) Anyways, I am a certified Fall Protection Competent Person Trainer, so I can legally provide training to anyone needing an Authorized Person (8 hour training) or Competent Person (24 hours) training to be eligible to work at a height on any job in any industry in the U.S. I am certified through 3M Safety which used to go by Capital Safety and they are for the most part the “golden standard” for fall protection equipment (DBI-Sala) and 3M products as well as research into fall protection as well as providing the training. If I had an incident on the job at Ft. Hood or any other job that I provided the fall protection training for, the first person they will look at is me. They will question my training, the course work I used, inspect my training logs, inspect the material I provided, etc…and if they find that I did not provide the adequate training necessary, I could be held in part for liability of the incident. We had a small incident where a guy didn’t have a lanyard connected to his harness. He was told to come down by the Corp. of Engineers Safety guy and asked if he knew he was supposed to have a lanyard. He tried to give the, “I didn’t know” card, but the safety guy told him he must and if didn’t again, he’d shut the job down. He then called me and began questioning our training program. He being new to safety, started questioning the company I went through’s training program (3M/Capital Safety), He then went and called 3M capital safety to get their training program and then told me that he was only aware of some other company that he knew provides training. He had me sit down with him and call them about providing an on-site training course. Kind of a slap in my face, but if this was what this guy wanted, then I’d do what it takes, but as we were talking to this company he suggested, I asked them if they actually created the training themselves and where they got their information. What do you think they said? They said that they have qualified trainers who took their training through 3M/Capital Safety lol. The Corp of Engineer Safety noob, kind of put his foot in his mouth after hearing that and we went about our business. Now, he recognizes 3M/Capital Safety as the standard in which FP should be trained by and uses them!So many times, I meet guys that all they’re after is the money and not truly in it for the true nature of helping people and saving lives. I’ve worked in Oil and Gas and I can tell you that half the Safety Consultants I met went through a couple weeks of in-house training, got on their rig or frac pad and only performed quality audits and when necessary wrote incident reports. But, they were being paid $1100 per day. I’ve worked in construction where safety companies are hired to come in and provide an 8 hour training course, but because the management was so concerned about production schedules, they asked the safety trainer if he could cut the training in half and say they did the 8 hour training and they agreed! I mean heck, they’ve made their money right, why spend 8 hours when I can do it in 4 and my customer is happy with it? Heck yeah! Not realizing that they are assuming liability for the training they’ve provided.Someone below wrote that there are a lot of companies out there that do stuff like this, but not many are good at them. He is absolutely right. The quality of training is only as good as the trainer and the passion they have for doing the job. If you’re asking how big the market is for an OSHA training company because you think it’s just going to make you big money really quick, you won’t last long.The market is good for quality OSHA trainers especially, within the construction, manufacturing, and Oil and Gas industries. However, the biggest question is are you willing to put yourself on the line for the training you’re willing to provide. Are you willing to say, Yes, I trained this person and here is how I did it, the material I provided, the quizzes they took, the final exam they took, the practical exercises we did, etc…If a company is going to pay you thousands of dollars to train their people, they fully expect the training is per standard and will take the liability of injury claims off their back.A huge reason some companies provide safety training besides it being required by law is to prevent lawsuits against the company. If a company can say, “we trained them, we gave them the information, we gave them the equipment, we did meetings and safety stand downs routinely, we encouraged safe work practices through incentive programs” and the employee still managed to hurt him/herself, the company can nearly wash their hands of your negligence let you deal with your own bills. If a company hires an outside company to perform the training, they are expecting you to take the brunt of that if it was to ever happen and if you can’t show that you did a quality job and kept up your record keeping and training logs, etc…you could be on the hook for a lot of money that could potentially drown you.Sorry for the lengthy and probably more than you’re asking for explanation, but as a person who truly loves safety and the service it provides, I wanted to ensure that the person asking this question saw the reality of what a company is taking on that does these types of things.Good luck and BE SAFE! Hope you have as successful safety career!
