Lockout Tagout for General Industry
63 flashcards covering Lockout Tagout for General Industry for the OSHA OSHA 10/30 General Industry section.
Lockout Tagout procedures in general industry are essential safety measures that control hazardous energy sources to prevent accidental machine startup during maintenance or servicing. This topic is defined by OSHA's regulation 29 CFR 1910.147, a core component of the OSHA 10 and 30 hour General Industry training, ensuring workers understand energy isolation techniques.
On OSHA certification exams, Lockout Tagout questions typically involve multiple-choice scenarios that test knowledge of the procedure's steps, such as identifying energy sources or applying locks and tags. A common trap is overlooking the requirement for group lockout in multi-worker settings, which can lead to errors in answering questions about shared equipment.
Remember, workers often skip verifying that all energy sources are fully isolated before starting work.
