Machine Safety: Is OSHA okay with my 'acceptable' risk mitigation?

“We have reviewed all of our machine safety hazards and have applied mitigation solutions to every hazard. Will OSHA agree with the mitigated 'acceptable' risk levels we’ve achieved?”

In my 40-plus years in manufacturing I’ve never seen OSHA agree with any level of applied machine guarding and administrative solutions. On the other hand, I have seen OSHA agree with an employee who has complained to OSHA about an unsafe situation. With that said, there are plenty of information resources that can help you (in manufacturing) understand all of the mitigation techniques available for each identified hazard. Some of these sources include; OSHA’s 29 CFR 1910.XXXX, and consensus standards like the ones listed as related reading the bottom.

After completing a risk assessment, the five levels of hazard mitigation described in machine guarding standards are:

1) Eliminate the hazard – design it out

2) Isolate the hazard with hard guarding

3) Add additional engineering, guards, devices, or layers of safety (controls or systems)

4) Administrative controls like – training, signage, assessments, etc.

5) Personal protective equipment (PPE) like - goggles, gloves, outer clothing, shields, etc.

All five levels are fully acceptable risk mitigation solutions to achieve that “acceptable” level of mitigated risk. In my opinion, that acceptable level of risk for a given hazard is intentionally left undefined because you are the one who defines the tolerable level of risk you or your company is willing to accept. It’s been my experience that you are in the best position possible as long as you’ve documented your complete process for each identified hazard including the steps of mitigation taken to achieve that “acceptable” level of mitigated risk. And, furthermore, that you have consistently met the periodic OSHA requirements for employee training and documentation. Lastly, have I mentioned documentation?

Having completed all of this – OSHA still will not openly agree, in my experience. What has your experience been? Please let us know if you agree or disagree?

Annual Salary Survey

Participate in the 2013 Salary Survey

In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.

Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
