Sample text
The building’s primary use and height lend clues as to what materials were likely to have been used in its construction. , skeletal systems in which both steel and concrete are used together such that neither material predominates over the other). Residential buildings tend to be shorter and supported by concrete. Although steel is still common for office and commercial buildings today, most residential towers are built with concrete (Ford, 1992). Structural materials may not, however, be the most potent hazardous materials in a building.
Furthermore, severity and immediacy of effects can also vary widely. 2. Prevelance in buildings or building materials: A chemical is not likely to create a hazardous exposure if it is not present in buildings in large enough quantities. The more common its uses are in buildings, the greater the potential for hazardous exposure at a building collapse site. Both of these factors (toxicity and prevalence) must be considered when assessing hazard at a building collapse. 16 Protecting Emergency Responders Forms of Chemical Hazards Most chemical hazards at a multistory-building collapse are present as coarse dusts, aerosol, or gases (visible or invisible).
Health effects of silica include acute and chronic silicosis, pulmonary tuberculosis, chronic bronchitis, chronic obstructive pulmonary disease, lung cancer, and possibly autoimmune diseases. Metals. Beyond structural applications, metals are used for pigments, piping, electrical devices, electronic components, lamps, architectural alloys, and wood preservatives. 3 provides a listing of common hazardous metals used in buildings. Ingestion, inhalation, or dermal contact may lead to hazardous exposure, although inhalation is the most important route for dust and particulate-type exposures generated at a structural collapse.
