Lockout Tagout in Construction
63 flashcards covering Lockout Tagout in Construction for the OSHA OSHA 10/30 Construction section.
Lockout Tagout in construction involves procedures to protect workers from hazardous energy releases during equipment maintenance or servicing, such as shutting down machinery and preventing accidental startup. This is defined by the Occupational Safety and Health Administration (OSHA) under 29 CFR 1910.147, which sets standards for controlling energy sources and applies to construction environments as part of OSHA 10/30 training.
On certification exams for OSHA 10/30 Construction, questions typically appear as multiple-choice scenarios testing the full sequence of lockout steps, like proper tagging and verification, or identifying violations in case studies. A common trap is overlooking the need for physical locks in addition to tags, which alone don't prevent equipment activation and can result in injuries.
Remember to always test for residual energy before removing locks.
