All types of blasting caps in strengths through No. 8 shall be rated at 1 1/2 (0.68 kg) of explosives per 1,000 caps. Note b. "Barricaded" means that a building containing explosives is effectually screened from a magazine, building, railway, or highway, either by a natural barricade or by an artificial barricade of such height that a straight line from the top of any sidewall of the building containing explosives to the eave line of any magazine or building, or to a point 12 feet (3.66 m) above the center of a railway or highway, will pass through such intervening or artificial barricade. Note c. "Artificial barricade" means an artificial mound or revetted wall of earth of a minimum thickness of 3 feet (0.92 m). Note d. "Natural barricade" means natural features of the ground, such as hills or timber of sufficient density that the surrounding exposures which require protection cannot be seen from the magazine when the trees are bare of leaves. Note e. When a building containing explosives is not barricaded, the distances shown in Table 1 shall be doubled. Note f. When 2 or more storage magazines are located on the same property, each magazine shall comply with minimum distances specified from inhabited buildings, railways, and highways, and, in addition, they shall be separated from each other by not less than the distances shown for "Separation of magazines," except that the quantity of explosives contained in cap magazines shall govern in regard to the spacing of the cap magazines from magazines containing other explosives. If any 2 or more magazines are separated from each other by less than the specified "Separation of magazines" distances, then such 2 or more magazines, as a group, shall be considered as 1 magazine, and the total quantity of explosives stored in such group shall be treated as if stored in a single magazine located on the site of any magazine of the group and shall comply with the distances specified from other magazines, inhabited buildings, railways, and highways. Note g. This table applies only to the manufacture and permanent storage of commercial explosives. It is not applicable to the transportation of explosives or any handling or temporary storage necessary or incident thereto. It is not intended to apply to bombs, projectiles, or other heavily encased explosives. Note h. 1 pound = 0.454 kg; 1 foot = 0.305 m.

(d) Other radioactive substances are present in the air in average concentrations exceeding 10% of the maximum permissible concentrations in the air recommended for occupational exposure as set forth in the 40-hour week column of table 1 of the national committee on radiation protection report no. 22, entitled "Maximum Permissible Body Burdens and Maximum Permissible Concentrations of Radionuclides in Air and in Water for Occupational Exposure," June 5, 1959, which is adopted by reference in these rules and is available for inspection and for distribution at no charge at the Michigan Department of Education, Office of Career and Technical Education, 608 W.
