Because the Construction/Contractors version includes both the SafeStart and SafeTrack programs, the combined concepts cover two of the three primary components of a world-class or optimum safety system.
SafeStart pertains to the safety awareness and personal safety skills development category and SafeTrack covers the observational component.
As an added benefit, the ToolBox series can also facilitate refresher training for the third component (your traditional safety program) by initiating conversation among employees around your own rules and procedures, proper equipment usage, etc. that you have in place.
More specific concepts are discussed in each of the SafeStart and SafeTrack pages or see the concept summaries.
