Things to re­mem­ber when re­pur­pos­ing any con­tainer with small stan­dard open­ings

The Shed - - Street Art -

• Al­ways as­sume that a con­tainer may have held a flammable liq­uid or gas in the past.

• Al­ways as­sume that a residue may still be present and can pro­duce an ex­plo­sive vapour.

• Al­ways fill the con­tainer to the ab­so­lute brim with wa­ter to elim­i­nate any air pock­ets that might har­bour an ex­plo­sive vapour be­fore you cut, weld, drill, or oth­er­wise ap­ply heat to the con­tainer.

• Do all your work on the con­tainer with it full of wa­ter.

• If you are open­ing the con­tainer, en­sure that the open­ing is of a suf­fi­cient size to pre­vent any gases from com­press­ing within the con­tainer, be­fore re­mov­ing the wa­ter.

These pre­cau­tions should ap­ply to ev­ery con­tainer, ir­re­spec­tive of size and con­struc­tion, in­clud­ing all pres­sure ves­sels.
