TinnerFlowThis site is designed to make an apprentice safer by helping them pause, verify, and ask better questions. It is not a replacement for training, supervision, engineered details, safety plans, or approved job documents.
Follow this order when there is a conflict: immediate safety direction, employer safety policy, project drawings/specs, approved submittals, manufacturer installation instructions, governing code/AHJ, and foreman or qualified-person direction. TinnerFlow sits underneath all of those.
It can help you identify the problem, gather measurements, document the condition, understand what might be risky, and ask your foreman a cleaner question with possible routes.
It cannot inspect your job, approve your installation, sign off a rated assembly, calculate engineered support, certify rigging, replace a manufacturer manual, or override the AHJ.
Use the cards to slow down: take photos, get the grid/room/elevation, verify the drawing revision, measure twice, compare to the submittal, and bring your foreman a clear A/B/C decision instead of guessing.
If there is an immediate hazard, stop work, move to a safe location, warn nearby workers if safe to do so, and follow your employer’s emergency and site-safety procedure.
