Non-DOT Approved<\/strong>” warning.<\/li>\n<\/ul>\nProper cleaning is essential for measuring the ability of the tank to be reused.<\/em><\/p>\n<\/span>Cutting Tanks Open Safely<\/strong><\/span><\/h3>\nMany repurposing projects require accessing a tank\u2019s interior by cutting it open. This is extremely dangerous and should only be attempted with proper precautions:<\/p>\n
\n- Fully purge the tank<\/strong> \u2013 Remove all gas by opening the valve underwater until the bubbles stop.<\/li>\n
- Research proper cutting procedures<\/strong> \u2013 Consult experienced welders on the safest torch, blade or saw type.<\/li>\n
- Mark cutting lines precisely<\/strong> \u2013 Use a straightedge and soapstone.<\/li>\n
- Clamp the tank securely<\/strong> \u2013 Use a sturdy vise or jig for stability.<\/li>\n
- Wear safety gear<\/strong> \u2013 Face shield, ear protection, fire-resistant clothes, etc. Have an ABC extinguisher nearby.<\/li>\n
- Make relief cuts first<\/strong> \u2013 Lightly score along cut lines to relieve internal stresses.<\/li>\n
- Cut slowly and cautiously<\/strong> \u2013 Apply heat\/force gradually, watching for issues. Stop immediately if anything seems unsafe.<\/li>\n
- Use an exhaust system<\/strong> \u2013 Position a hose near cut point to evacuate hot fumes.<\/li>\n
- Inspect carefully afterwards<\/strong> \u2013 Allow cooling, then thoroughly check for cracks or defects.<\/li>\n<\/ol>\n
Rushing the cut or using the wrong tools can cause explosions and serious harm. Consult an experienced professional if you are uncertain about it.<\/em><\/p>\n<\/span>Modifying Valves and Fittings<\/strong><\/span><\/h3>\nValves and fittings play a critical safety role by controlling gas flow. When repurposing tanks, you may need to modify or replace these parts. This requires care to prevent leaks.<\/p>\n
