Stop! Is your machine safety life cycle program in place?

For machine safety, having a Safety Life Cycle Program in place sets the stage for increased compliance to OSHA regulations and consensus standards, and it helps drive a higher level of functional safety for each application.

JB Titus, CFSEFor machine safety, having a Safety Life Cycle Program in place, in my opinion, certainly sets the stage for increased compliance to OSHA regulations and consensus standards. It also helps drive a higher level of functional safety for each application by taking on a more practical approach to your safety system design.

     I believe the system designers need to be willing to implement and apply various new safety technologies and approaches to drive the resulting benefits.

     There are several approaches, models, and solutions for this approach to machine safety compliance. You can find a sample listing at the bottom of this blog. One thing consistent with each approach is that a successful Machine Safety Life Cycle program is definitely dependant on the respective Safety Culture within a company.

     An existing strong and effective Safety Culture is needed to provide the foundation for this more detailed and systematic process for machinery applications. The functional safety life cycle is defined in IEC 61508 plus many of the example models involve five or six continuous life cycle steps for the safety system:

     1) Risk Assessment & Hazard Analysis

     2) Functional Specification

     3) Design & Verification

     4) Installation & Validation

     5) Maintain & Continuous Improvement

     What are your thoughts about this life cycle approach to machine safety compliance? Is your Safety Culture already in place and are you practicing the requirements of IEC 62061 and ISO 13849-1? These standards are performance based and designers/implementers of machine safety are able to actually quantify the value of safety. However, will this deterministic approach actually reduce the cost of machine guarding by developing an improved level of safety for each safety function? What about machine sustainability?

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.
