Plain-English Summary
The Dingfelder Field Handbook™ is a practical field reference, not a substitute for official standards, OEM manuals, site safety procedures, qualified tradespeople, engineering review, or code authority.
Field Reference Only
The handbook supports understanding, training, troubleshooting, field judgment, and safer technical thinking. It does not authorize unsafe work and does not replace the controlling safety process.
Site Safety Rules Come First
If a handbook page appears to conflict with site safety rules, lockout/tagout procedures, OEM instructions, engineering direction, permit requirements, or regulatory authority, the controlling site and legal requirements take precedence.
Lockout/Tagout and Stored Energy
Industrial systems may contain hazardous energy even when they appear stopped. Hazards may include electrical energy, mechanical motion, gravity, hydraulic pressure, pneumatic pressure, vacuum, heat, chemical energy, spring tension, rotating inertia, suspended loads, residual pressure, and automated restart conditions.
Qualified-Person Boundary
Electrical work, welding, structural work, pressure systems, lifting devices, confined spaces, hazardous materials, explosive atmospheres, machine guarding, robotics, crane work, fall protection, code-regulated systems, and engineered modifications may require qualified or licensed personnel.
Emergency Boundary
If a condition involves fire, explosion risk, hazardous gas, chemical release, electrical arc, injured person, trapped person, collapse risk, active machinery hazard, oxygen deficiency, uncontrolled pressure, or any immediate threat to life or health, stop using the handbook and follow emergency procedures.
AI and Calculator Boundary
Calculators and AI support judgment. They do not replace verification. A wrong input can produce a wrong output, and a correct calculation can still be unsafe if the application is misunderstood.
