Local Law 196 applies to all NYC jobsites with a Site Safety Plan. Supervisors must have 62 hours of SST Supervisor training and an SST Supervisor card. Because of Local Law 196 of 2017, the New York City Department of Buildings (DOB) now requires construction and demolition workers at most major worksites in the five boroughs to have 40 hours of Site Safety Training (SST) and an SST Worker card.
