Safety Disclaimer
TinnerFlow is field guidance for learning and preparation. It does not replace training, supervision, approved project requirements, or qualified professional judgment.
Use the approved source
Final installation decisions must follow the latest approved shop drawings, project specifications, adopted code, product listings, manufacturer instructions, employer safety program, and foreman or superintendent direction.
Stop before guessing
Do not proceed when structural capacity, rigging, fall protection, electrical clearance, fire or smoke requirements, hazardous materials, chemical compatibility, welding authorization, equipment startup authority, or a required inspection is unclear.
Site conditions control
A guide cannot see the actual structure, material condition, system pressure, exposure, access, crew training, or project-specific detail. Verify those conditions in the field before work continues.
Report a correction
Field methods vary by system and project. Report wording that could cause an unsafe or failed installation through the Contact page.
