Skin disease is a factor whose influence can lead to injury or other significant immediate damage to human health or to a fatality. Mixtures are slaked lime, paint, thinner, solvent, varnish and seals are very harmful when exposed to skin. Dangerous factors should also include electricity and burst pressure equipment (cylinders, boilers, and tanks), pipes and gas equipment, gas mixtures with air. Risk of explosion may be related to improper handling of equipment and leaking pipes and connections, as well as disability measurement and control equipment and safety devices. The presence of toxic, harmful, irritant or corrosive in contact with the skin involves the use of personal protection equipment.
2) Hearing Problems
Construction work requires more mechanical work thus creating lot of sound which causes harm to the ear, thus creating hearing problems for the worker on the site. Disruptive factor does not represent a threat to human life or health, but makes it difficult to work or contribute in a significant way to reduce its ability to do work or other activities or reduces productivity. The underground places of work and energy usher in a technological landscape, where the issue of security redeems the role at the service of the superior spaces of representation. Work that involves the use of pneumatic tools or swing; workings of the timber; work within the technological plants.
3) Bone and muscular disease
Due to unnatural working postures and handling of heavy and difficult machine during construction work, causes bone and muscular disease. Basic requirements and collective protection against potential threats, which can cause mechanical factors and electricity, are discussed in the sections relating to machinery and equipment and individual works.
Disasters and reconstructions, ruins and new cities are compared as the words of a single story in an ordered sequence of images from the succession proposal establishes a hierarchy, a critical approach to which watch. Earthquakes, landslides, floods, fires, wars are some of the disasters that have marked the identity of our cities, are the circumstances of a fatal inextricably intertwined history to progress is not affected by emergencies. No celebration of evil is demonstrated for the drama underlying the attention, if not in relationship with architecture that accompanies it, trying to anticipate it, now he studies the causes and consequences to overcome the danger. The route is a comparison of the emotional landscapes and new architectures that recompose the image of many cities, art the ability to evoke feelings in a concise otherwise inexpressible, architecture stability of new births.
The spirit necessary to look at the pictures of disasters is to be able to predict the strength of reconstruction, which can only be understood in retrospect loaded in a time perspective, throughout history, the role of driving towards a situation of calm safe for society. Architects and engineers have built and rebuilt tenaciously our cities from San Francisco to Messina, from Lisbon to Berlin, to the ...
