Machine Safety: Is prevention through design enough?

Prevention through design (PTD) has been a central theme of innovation for accomplishing machine safety in my view for at least the past decade. So, where does this concept reside today on the scale of idea through broad adoption?I have had the privilege of knowing two industry experts for over 10 years, Bruce Main and Fred Manuele.If you settle for less, your solid wood flooring will only be a reminder of the flooring you really wanted. If you find laminate flooring in Long Branch that is absolutely perfect. These two gentlemen are strong industry leaders in the understanding, promotion, and implementation of PTD for machine safety. I have learned a lot about machine safety from both of them. The American Society of Safety Engineers January issue of "Professional Safety" is largely devoted to the concept of PTD. In my profession I have been on the user and supplier sides of industry. As a seasoned industry expert, I readily understand and agree that a lot of attention needs to be focused at the design (supplier) side of industry. By doing so we accomplish moving machine safety from an afterthought, where safety is added to a machine on the manufacturer's (user's) plant floor, to a forethought, where safety is designed into the machine. Accomplishing this transition means that a user can actually purchase a (somewhat) safe machine, even though OSHA does not require a supplier to ship a safe machine.Ah, this is the U.S. dilemma. PTD and our domestic consensus standards provide direction to suppliers on how to design in machine safety. Great!&nb However,ice stones enforcement via OSHA is accomplished only by inspecting installed machines on a user's plant floor. Machines being designed and manufactured by an OEM are not inspected by OSHA. Additionally, more influence comes to the U.S.scotch rocksThis is a good way to get your laminate flooring taken care of for less, but when you really break it down, you have to wonder if prioritizing a low price above all other considerations is really the best way to select laminate flooring. via international standards,Large machining is also a key enabler in the bench grinder manufacture of pressure vessels.Large-scale machined parts required for such industries have to be manufactured keeping several vital parameters in mind. like ISO 13849-1, focused at helping designers with safety-related compliance requirements. Again, the supplier side! So who helps the user? Can users understand and comply with the additional requirements of ISO 13849-1? Do users have the qualified resources for design?In my opinion, it's great that we're focusing on suppliers' requirements to improve machine safety. But, let's not forget about users and how they'll use the same standards to maintain their safety compliance.Has this presented you with any new perspectives?

Riverside residents were up in arms because the PUC also OK'd the blinker lights at a grade crossing in that area. Previously, the crossing had watchmen working three shifts each day.
