A=COM aggregate, provide means to flush eyes (e.g., eyewash station, bottles)for 15 minutes. If the material contacts skin, wash skin with water and ph-neutral soap or mild detergent. 4.2.12 Provide temporary winter protection enclosures with adequate ventilation, lighting, and fire protection. 4.2.13 Equip pavers with a loud warning bell or horn that sounds when a paver moves ahead or the bucket is run out. 4.2.14 Provide conical or tapered bottoms with mechanical or pneumatic means of starting the flow of materials for bulk storage bins, containers, or silos. 4.2.15 Construct handles on bull floats used where they may contact energized electrical conductors of nonconductive material, or insulate with a nonconductive sheath whose electrical and mechanical characteristics provide the equivalent protection of a handle constructed of nonconductive material. 4.2.16 Do not extend handles of buggies beyond the wheels on either side of the buggy. Installation of knuckle guards on buggy handles is recommended. 4.2.17 Provide concrete buckets equipped with hydraulic or pneumatically operated gates with positive safety latches or similar safety devices installed to prevent premature or accidental dumping. The buckets will be designed to prevent excess aggregate and loose material from accumulating excessively on the top and sides of the bucket. 4.2.18 Block the wheels of ready-mix trucks and set the brakes to prevent movement when discharging on a slope. 4.2.19 Properly guard exposed gears, chains, and rollers of mixers. 4.2.20 Secure sections and ends of tremies, elephant trunks, and similar concrete conveyances with wire rope, chain, or similar safe fastener. 4.2.21 Equip powered and rotating-type concrete troweling machines that are manually guided with a control or dead-man switch that will automatically shut off the power whenever the operator removes his hands from the equipment handles. 4.2.22 The use of ready-mix concrete trucks may create traffic problems,which proper planning and care can lessen and/or eliminate. Control backing operations through the use of a properly trained and attired flag person/spotter who will be positioned so that they have a clear view of the area behind the truck, as well as be clearly visible to the truck driver. Route movement of personnel and project equipment away from this area so that they do not have to cross the truck's means of egress. 4.3 Forms and Shoring 4.3.1 The completed shoring setup should be a homogenous unit or units. For example, do not use tubular steel shoring in combination with adjustable wood or jack-type shoring. 4.3.2 Confirm that formwork and shoring are be designed, erected, supported, braced, and maintained so that they will safely support all vertical and lateral loads that may be imposed upon them during placement of concrete. 4.3.3 Confirm that drawings or plans showing the jack layout,formwork, shoring,working decks, and scaffolding are available at the jobsite. 4.3.4 Remove and stockpile stripped forms and shoring promptly after stripping in all areas in which persons are required to work or pass. Remove and dispose of adhered concrete from forms and planking before stacking when possible to prevent generation of concrete dust. Pull, cut, or remove by other means any protruding nails,wire ties, and other form accessories not necessary to subsequent work to eliminate the hazard. 4.3.5 Do not impose any construction loads on the partially completed structure unless such loading has been considered in the design and approved by the engineer-architect. 4.3.6 When temporary storage of reinforcing rods, material, or equipment on top of formwork becomes Concrete(S3AM-338-PR1) Revision 1 July 31,2019 PRINTED COPIES ARE UNCONTROLLED.
