translate: About tank inventory while driving

Not first, then means prior to proceeding, it means before driving. Check with supervisors prior to start-up to ensure minimum inventory to maintain start-up operations. How much is enough should be calculated based on the process and planned test run time. It consumes 10 tons of raw materials per hour, and the test run takes approximately 3 days. The minimum raw material inventory should be 24x3x10=720 tons.

It is essential that tanks have adequate inventory levels to support start-up prior to proceeding, check with supervision to determine the minimum inventory required to support startup and operation. Before start-up, if there is no feed from the upstream of the device or there is no qualified feed, a storage tank needs to be used to store enough volume to drive into the reactor (tower), because it is impossible to run an empty tower.

My comma was in the wrong place, no wonder I had to understand! It is essential that tanks have adequate inventory levels to support start-up, prior to proceeding check with supervision to determine the minimum inventory required to support startup and operation. Thank you all!

Ordinarily, if "prior to proceeding" is placed at the beginning of the sentence, there should be a comma after it. Now I'm confused as to where to put this comma. This post was last edited by echommm on 2009-3-27 17:57 ]

There is no comma in the original sentence, and the comma position in the echo on the third floor should be correct. The fourth floor is my original understanding, which is probably incorrect. Maybe some foreigner's writing is not very standard. I think it should be like adding a comma or period on the third floor, otherwise it will be difficult to understand.

It is essential that tanks have adequate inventory levels to support start-up prior to proceeding check with supervision to determine the minimum inventory required to support startup and operation. Prior to is added to the vocabulary book prep. before... a brush used to apply lather prior to shaving. A brush used to apply soap before shaving. heat a metal prior to working it. soak the metal before working it.

prior to = before usage: prior to sth/prior to doing sth. Original sentence: It is essential that tanks have adequate inventory levels to support start-up prior to proceeding check with supervision to determine the minimum inventory required to support startup and operation. My guess: 1. The original sentence is missing only one punctuation mark (a comma). There is a problem with the wording in the original sentence. Change it to: It is essential that tanks have adequate inventory levels to support start-up to be progressed. Check with supervision to determine the minimum inventory required to support startup and operation. But this is unreasonable, because the word "proceed" implies that the start-up is already in progress, so there is no way to check the inventory only while the start-up is in progress. Therefore this inference is not valid. 2. The original sentence is missing two punctuation marks (a period and a comma): It is essential that tanks have adequate inventory levels to support start-up. Prior to proceeding, check with supervision to determine the minimum inventory required to support startup and operation. In this case, proceeding does not refer to start-up, but should refer to something else (such as feeding materials to a storage tank, etc.). See what is said in front of this sentence? Please read more about the context before deciding. My first impression was that the sentence was broken after poceeding, but later I felt that the sentence was broken after start-up. It seems confusing to read, and the original text is not standardized, thus causing confusion in understanding. I hope you all will continue to express your opinions.

The following is the correct sentence fragment. The original text is missing a period and a comma. It is essential that tanks have adequate inventory levels to support start-up. Prior to proceeding, check with supervision to determine the minimum inventory required to support startup and operation.
