The utilization of bolt setting tools (cartridge-operated fixing tools) which guarantee maximum flexibility and mobility since the worker does not depend on stationary energy supply (via electrical cable or high-pressure air line) has gained substantially in importance for roofing and paneling of industrial buildings with trapeziform profile metal plates. In order to allow the surveillance of work safety requirements and to ensure preventive occupational safety and health, it is essential to find out when, where, and for how long, how often and with which tools, with which bolts and materials, with which power charges, and in which body postures and under which working environment conditions work is carried out. Intensive work analyses showed, e.g., that for the workers' effective noise exposure, the most relevant tasks are the setting of bolts through metal plates into steel and into scaffolding-like steel constructions with various noise transmission mechanisms. The impulse noise in this context is not only due to a bolt setter's own work, but also other operators of a team in the immediate surroundings. Because of the large number of bolts which are set in a typical work day (approximately 800) with peak levels between 120 and 150 dB, the additional noise level on a construction site (even at a continuous noise level of approximately 85 dB(A)) is not of much practical relevance for a calculated rating level using the energy equivalence principle. However, the effects of such continuous noise should not be completely disregarded either. The fact that bolt setters oftentimes must lean forward in order to apply the necessary pressure to set a bolt aggravates the problem because of the reduced emission-immission distance which can lead to impulse noise at peak levels which are a danger to the hearing. Additionally, impulse noise can disturb the work course, can be detrimental to work safety, and can be a nuisance. Frequent changes in body posture and varying use of tools almost necessarily leads to varied noise immissions. Thus, there is some debate whether standardized noise emission measuring methods (e.g., according to DIN 45635-34, 1984) are suitable for the reality on a construction site.
