This is one of those MUST READ studies for all safety professionals who deal with machine gaurding and interlocks, and/or have a behavior based safety process!  Although the study was done on Computer Numerical Control (CNC) machines in the UK, we can certainly see how the results can be expected on ANY machinery and by ANY…...

Identifying human error is a starting point, not a conclusion.

There are two aspects to managing error:… Membership...

In the USA, we can look to OSHA’s PSM Compliance Directive, CPL 02-045, to get an idea of what we should consider “human factors”…...

Another major incident investigation finds serious cultural failures, poor training for operators and emergency responders, poor emergency planning, and technical failures in the Mechanical Integrity program.

The investigation found that…...
