• Follow the torque sequence and values specified for each flange bolt connection.
• Use flange alignment tools to position flanges — never use your fingers between faces.
• Install pipe supports and hangers before loading pipework onto the bracket system.
• Use mechanical lifting for heavy pipes and flanges that exceed safe manual handling limits.
• Obtain a hot works permit before welding or brazing any pipework on site.
• Follow LOTO procedures before breaking into any existing pressurised pipe system.
• Establish exclusion zones during pressure testing of completed pipework installations.
• Wear cut-resistant gloves and eye protection when cutting or handling pipe sections.
• Check gasket type and specification match the design before assembling flange joints.
• Inspect completed joints and record torque values as required by the inspection plan.

• DON'T tighten flange bolts without following the specified torque sequence and values.
• DON'T place fingers between flange faces during alignment — use the correct tools.
• DON'T load pipework onto brackets before supports and hangers are installed.
• DON'T manually handle heavy pipes when mechanical lifting equipment is available.
• DON'T weld or braze pipework without a valid hot works permit in place.
• DON'T break into pressurised systems without confirmed LOTO isolation procedures.
• DON'T stand near pipework during pressure testing — stay outside the exclusion zone.
• DON'T handle cut pipe ends without gloves — sharp edges cause deep lacerations.
• DON'T use incorrect gasket types — mismatched gaskets cause joint leaks under pressure.
• DON'T cover flanged joints before inspection and torque records are completed.
