b) The section magazine must be on the return air side of the section and placed in a crosscut or idle room neck a minimum of ten (10) feet from the roadway.

c) The area around the section magazine must:

1) be barricaded to prevent any machinery or person, other than a shot firer, a mine manager, or the section foreman from entering the area;

2) be dry;

3) be rockdusted to meet the requirements of Section 24.05 and 24.06 of the Act (Ill. Rev. Stat. 1985 ch. 961/2, pars. 2405, 2406)

4) be free of combustible material; and

e) Only a forty-eight (48) hour supply of permissible explosives, including any surplus remaining from the previous day, will be allowed in the section magazine. Each mine inspector can determine what a forty-eight (48) hour supply is for each mine based on the written inventory records of usage which 62 Ill. Adm. Code 225.47 requires.

h) At the beginning of each shift, the shot firer must examine the roof around and over the section magazine where permissible explosives are stored.

i) The shot firer must keep permissible explosives or electric detonators in their approved containers until immediately before use at the working face.

j) Tools or other materials must not be stored with permissible explosives or electric detonators.
