Health and Safety at Work: System and Statistics. 1992. In 1979, Danish scientists suggested that reducing hexavalent water-soluble chromium to trivalent insoluble chromium by adding ferrous sulphate during production would prevent chromium-induced dermatitis (Fregert, Gruvberger and Sandahl 1979). Usually, for all known materials, values for yield stress and ultimate stress are readily available. They should be filled only after they have been shut down and allowed to cool off. Failure to meet the required power supply, malfunction will occur in the part of hand tools or equipment.2. 10 . 4 0 obj The handrail at each extremity of the escalator, where the steps move horizontally, should extend at least 0.30m beyond the landing plate and the newel including the handrail at least 0.60m beyond (see figure 5). For beams and roof trusses of considerable span, glue-laminated wood units are used. The risk of sprains and strains can be reduced if two or more workers work together on strenuous tasks, and more so if draught animals or powered machines are used. The Association franaise de normalisation (AFNOR) is in charge of the Secretariat of this Technical Committee. So for a better design, the factor of safety should be always greater than 1. Their use is associated with many occupational injuries, particularly those caused by falls from heights (see also the article Lifts, escalators and hoists in this chapter). Accidents resulting from breakage of form panels misused as scaffold platforms are still rather frequent. Schneider, S, E Johanning, J-L Bjlard, and G Enghjolm.
