Current through Register Vol. 43, No. 1, October 31, 2024
Section 480-3-4-.02 - Quarry Banks(1) Guards (a) Excavations shall be provided with substantial railings, at points where passageways, tracks, roadways or buildings adjoin such excavations.(2) Loose Material (a) All quarry walls shall be kept free of unsafe loose materials. Unsafe overhanging material shall not be permitted.(3) Lifts (a) No person shall be permitted to attach block chains to a lift, or drill, load or do any work about a working face until such working face has been personally examined by the pit or quarry foreman or his assistant. If the working face is found unsafe, it shall be made safe by workmen under the personal supervision of the pit, quarry or blaster foreman before permitting other men to commence work.(4) Scaling (a) All walls where men are in danger shall be thoroughly scaled at least once each week, after heavy rain, after each heavy shot has been fired and after each freeze and thaw. When rock walls are smooth with little or no fracturing and not subject to open joints or presence of seams of clay or inferior rock, and past experience has proved that alternate freezing and thawing, heavy rains and heavy blasting are not productive of rock falls, this requirement shall not apply. In such cases, the superintendent of the quarry, or the foreman in charge of this kind of work, shall make frequent inspections of the face of the quarry and of the overburden below which men are employed and shall cause to be dislodged any slabs of rock, or boulders that make working conditions unsafe below. Scaling of quarry walls or pit banks from skips or mechanical shovel or crane buckets operated by hoisting machinery shall be prohibited.(5) Benching (a) In all quarries or pits where churn or well drilling is not employed, except building stone quarries, a bench or set back of at least ten (10) feet shall be made for every forty (40) feet or less of depth excavated. All benches shall be kept free from unsafe loose material.(6) Trimming Bars (a) Trimming bars, extension ladders and safety ropes shall be provided, where necessary, and maintained in good condition for the trimming of loose rock from the quarry edge.(7) Slope of Material (a) Rock piles shall be kept safely sloped during loading operations.
