BUILDING CONSTRUCTION AND MAINTENANCE A=cross-secbonal area of Umber in square inches L=unbraced length of Umber in inches D=least cross-sectional dimension of timber m inches Shores or braces should be set at an angle not greater than 30 degrees from the hori zontal For excavations more than 16 ft deep or where heavy lateral pressures are encountered, interlocking steel sheet piling is recommended Ladders Construction of all ladders should con form to the provisions of state and local ordinances, if any, and the applicable ladder safety code Special-use climbing equip ment, such as the combination stepladderwork platform shown in Fig 15-8, also should be constructed to comply with the applicable codes.

MANUAL HANDLING AND STORAGE OF MATERIALS An automatic sprinkler head, protected by a basket guard, may be installed made the bin.

PRINCIPLES OF GUARDING where a moving part crosses the fixed part of a machine is illustrated by the tables of a planing mill, the side of a shaper, spot welders, and clamping fixtures.

MACHINE TOOLS TABLE 24-1 DIMENSIONS FOR BAND TYPE GUARDS FOR ABRASIVE DISKS guard is to retain the pieces of the disk or wheel if it should be broken in operation Safety guards (protection hoods) should be constructed so that In changing wheels there is no need for removing the peripheral member which Is connected to the machine Guards on machines used for dry grinding should have provisions for connecting to an exhaust system Table 24-H gives the material specifications for safety guards Safety guard is a general term and in cludes all of the following specific types Band type guard Cast guard Drawn steel guard Fabricated guard Revolving cup type guard A band type safety guard is designed es pecially for an abrasive disk where grinding is done only on the exposed side of the disk and where its diameter remains constant The band type guard differs from other safety guards in that it consists only of a properly supported peripheral member or band This band is continuous and com pletely surrounds the disk, and though Its diameter is only sbghtly larger than the disk diameter, it need not be as heavy as other types of guards tliBt are used on abra sive wheels A band type guard should be made of wrought iron or steel plate or other mate rial of equal or greater strength It should be continuous and should conform as closely as practicable to the periphery of the disk The ends should be riveted, bolted, or weld ed together so as to leave the inside of the band free from projections The inside diameter of the band should be not more than 1 in larger than the outside diameter of the disk The band should be wide enough and kept in position so that at no tune will the disk protrude beyond the edge of the band farther than maximum exposure (G) indi- 24-22

HAND AND PORTABLE POWER TOOLS hardened and tempered, only an emery wheel, grindstone, file, or oilstone need be used to keep the head in shape and the edges clean and sharp.

PERSONAL PROTECTIVE EQUIPMENT Fig. 36-17a.

PERSONAL PROTECTIVE EQUIPMENT The garments should be of good quality leather, solidly constructed, and provided with fastenings to prevent gaping during body movement Fastenings should be so designed that the wearer can rapidly and easdy remove the garment There should be no turned-up cuifs or other projections to catch and hold hot metal Pockets should have flaps which can be fastened shut For ordinary protection against hot met al, radiant heat, or flame hazards of some what more intensity than those represented by welding operations, asbestos and wool, as well as leather clothing is used.
