Building hoists are temporary installations used on construction sites for the transport of persons and materials. Crushing is prevented by providing sufficient headroom at the top of the hoistway between the roof of the car in its highest position and the top of the shaft and a clear space in the pit where someone can remain safely when the car is in its lowest position. However, these are more frequent among cement users (e.g., bricklayers and masons) than among cement manufacturing plant workers. Cranes must be rated properly so that there are enough safeguards to prevent accidents caused by overloading and instability. are free of dust, grease, and 1. chemical hazard Protection against falling down the hoistway is obtained by solid landing doors and an automatic cut off that prevents movement of the cab until the doors are fully closed and locked. The base of the scaffold should be placed on a firm, level surface. Finland followed with a legislative decision at the beginning of 1987, and Sweden and Germany adopted administrative decisions in 1989 and 1993, respectively. Ergonomic hazard Even though the epidemiological data to date are inadequate to demonstrate with a reasonable degree of scientific certainty that asphalt presents a cancer risk to humans, general agreement exists, on the basis of experimental studies, that asphalt may pose such a risk. The steps are guided by rollers on tracks which keep the step treads horizontal in the usable area. But welding of stainless steel can expose workers to chromium and nickel fumes. Brussels: CEN. The proper layout of concrete transfer points and their equipment with mirrors and bucket receiving cages obviates the danger of injuring a standby worker who otherwise has to reach out for the crane bucket and guide it to a proper position. Excellence. Geneva: ISO. The power source itself can cause injuries or death, for example, through electrocution with electrical tools or gasoline explosions from liquid-fuel tools. Subsequently, gastric ulcers were induced in both guinea pigs and a dog fed on cement dust. Polynuclear aromatic compounds, Part 4: Bitumens, coal tars and derived products, shale oils and soots. Prefabricated scaffolds are assembled from parts manufactured in accord with standardized procedures that are permanently attached to fixation devices. 1992. Figure 1.
