Attached Table 3

1. The adjusting time for under-high-pressure (or in-compressed-air) worker shall be determinedby the following procedure:

(1) The adjusting time shall be determined by the point to be plotted on the scale corresponding to the body (internal) gas pressure coefficient based on the pressure range listed in the pressure column and the time listed in the column for the duration of work under high pressure(or in- compressed air), which are to be determined according to the pressure under which the previous work was carried out and the duration of such work carried out in Table 2 (Refer to Table 1, if the worker concerned falls under the category of the case designated in a), item3 of Article 15 and the case designated in item 2 of paragraph 1 of Article 18).

(2) Plot the point corresponding to the decompression time provided by Article 15 for the worker  worked in the high-pressure room on the scale .

(3) Connect the points determined on items (1) and (2) mentioned above with a straight line, and plot the point at which the straight line intersects the scale .

(4) Plot the point corresponding to the pressure of the high-pressure room where in the work  concerned has been carried out on scale , and connect this point and the point plotted on scale with a straight line to locate the point at which this straight line intersects scale .

(5) The value determined by item (4) shall be adopted as the adjustment time for workers working in the high-pressure room.  

(6) Despite the rule set forth in the above item (5), in the case of the worker who regularly engages  in the high-pressure room 3 times or more in a day, in determining the adjustment time for such worker, the adjustment time of the last work in the high-pressure room determined by the procedure set forth in the above items (1) through (5) shall be added to the duration of the last work under high pressure; this length of time shall be treated as the duration of the last work under high pressure  of this worker described in item (1); then, the procedures set forth in the items (1) through (5) shall be repeated to determine the adjustment time required for the worker who worked in the  high-pressure room; and this procedure shall be repeated according to the number of times of the work in the high-pressure room to determine the adjustment time required for the latest work under high pressure carried out by the worker concerned.

    2. To determine the adjustment time for the diving worker, the procedure for the worker to work in high-pressure room set forth in the above section 1 shall be applicable with necessary modifications.

  For instance, in applying the procedure written for the work under high pressure, the expression "worker in high pressure room" shall be read as "diving worker"; "work in compressed air" as " diving operations"; "pressure" as "depth of water"; "duration of work under high pressure" as "duration of diving"; "column for pressure" as "column for diving depth"; "column for duration of work under high pressure" as "column for duration of diving"; "Article 15" as "Article 27"; and "gas pressure reducing time for the worker in high-pressure room" as "gas pressure reducing time for diving worker".
