In a first respect this invention is a container, comprising: a cylindrical, hollow body capped on both ends by a base and a top; a conduit that bisects the top and extends into the interior of the container; and a perforated housing that encompasses the portion of the conduit that extends into the interior of the container. In another broad respect, this invention is a removable splash guard, comprising: a housing having a top and bottom that define an internal space; a lower tube that bisects the bottom, wherein the lower tube has a upper portion which is angled; an upper tube that bisects the top, wherein a portion of the second tube that extends into the internal space contains at least one hole; and a partition interposed between the upper and lower tubes that serves to block movement of a chemical from the lower tube to the opening at the inboard end of the upper tube. In another respect, this invention incorporates a flow restrictor of any type or material into the inlet or outlet tubing to reduce the pressurization or de-pressurization steps in a line drain sequence.

1. A method for the depressurizing a canister that contains a chemical, comprising: attaching a splash guard to a line that runs to the canister; attaching a second line and valving that connects the splash guard to a vacuum source; subjecting the canister to a vacuum as a depressurization step

1. A method for the depressurizing a canister that contains a chemical, comprising: attaching a splash guard to a line that runs to the canister; attaching a second line and valving that connects the splash guard to a vacuum source; subjecting the canister to a vacuum as a depressurization step; re-pressurizing the canister by introducing a gas into the canister through the outlet. 2. The method of claim 1 wherein the splash guard comprises a housing having a top and bottom that define an internal space; a lower tube that bisects the bottom, wherein the tube has a upper portion which is angled; a upper tube that bisects the top, wherein a portion of the upper tube that extends into the internal space contains at least one hole; and a partition interposed between the upper and lower tubes that serves to block movement of a chemical from the lower tube to the opening at the inboard end of the upper tube. 3. The method of claim 2 wherein the partition is an angled plate that is affixed to the upper tube. 4. The method of claim 2 wherein the upper portion is at approximately a right angle to the remainder of the lower tube. 5. The method of claim 2 wherein the lower tube is attached to a coupler outboard to the internal space. 6. The method of claim 2 wherein the upper tube is attached to a coupler outboard to the inner space. 7. The method of claim 2 wherein the upper tube includes one or more holes on the of the upper tube. 8. The method of claim 2 wherein the upper tube is closed on the inboard side. 9. The method of claim 2 further comprising a line that connects the upper tube to a canister containing a chemical. 10. The method of claim 2 further comprising a line that attaches to lower tube. 11. The method of claim 2 wherein the upper and lower tubes, the housing, and the partition are made of stainless steel. 12. The method of claim 2 wherein the upper tube is fitted with a gasket or particle filter to restrict flow through the upper tube.
