Safety concerns due to improper use of equipmen t Field Ot1tlng or Reinforcing Bars. Various means are used to cul rcinfon:ing bars at the jobsile. The smaller size bars, #'3 to 115, can usually be cut with boll­ cuncrs. All bar sizes ca1\ be au with an abrnsive S3W or by ftame-curting mch a$ u,ing an oxy-aa:,ylcne ton:b. fllmw. cutting of epoxy-c03ted reinforcing bars is not recommended. Any damaged bar =tings must bc r,:ptir,:d. Reprding Oam<>cutt ing. l C3U ha\. : sbown that u,y effect of ftame-cuning is localized 10 lbe end-cut surfaces. Only a very short distance, approximately 3/16 inch, from tbe llan>e-<UI eacls is alfected. From the te SIS it was concluded that flame-cuning had no adverse elfec,s. SPLICES* Reinforced concrete structures ar e gc,,cnlly designed so lhat the scpmtc parts act as a single unit, making it necessary to properly locate construction joints and provide continuity in the reinforcement through the joints. Just as it is im PQ6-sible to place all the concme at one time, it is aloo impossible to p<CMde full laigth continuoos reinforcing bars in most structures because of manufacturing, fabrication,or t Jan Sportation limj1. a1jons. Because splices i. o reinforcement can­ not be avoided, it is ncca.,ary for tl,e Engineer to provide fo,-prope,1y designed splices, a J\d to identify their lengths and locations on the slf1ld1Jfal drawings.
