The reality for concrete contractors today is that buried hazards not only exist, but must be worked around.
To help, the Association of Equipment Manufacturers (AEM) developed Best Practice Guidelines for Addressing Buried Hazards. The guidelines document was prepared by AEM's Masonry and Concrete Saw Manufacturers Institute. The group also has a working relationship with the Concrete Sawing and Drilling Association.
The guidelines are presented in an easy-to-understand "tips" format that covers locating and disabling a variety of hazards.
Even after all proper preparation work to mitigate an accident is done, there is no guarantee that one will not occur. The guidelines, therefore, also discuss implementation of a well-rehearsed response plan.
