Safety requirements

NapaSan considers safety to be paramount. We require contractors that work for us on projects to have the same dedication to safety. This is accomplished through an assessment of the contractor’s safety programs. This assessment takes into account, among other variables, the contractors workers’ compensation experience modification rate (EMR), recordable incident rate (RIR), and lost time incident rate (LTIR). For more information on contractor’s safety qualification criteria please contact the NapaSan Accountant at (707) 258-6000.
