Biological Hazards on Construction Sites
-
Types of Biological Hazards
-
Biohazards are often found in water systems and sewers, conduits which may contain bacteria and biological waste. In the United States, many sewer systems are antiquated. Their lack of structural integrity and the lack of regular maintenance increase the likelihood that biohazards will pose serious threats.
OSHA and Bloodborne Pathogens
-
Bloodborne pathogens represent another threat. The Occupational Safety and Health Organization (OSHA) has instituted a Blood Borne Pathogens Standard to control and minimize blood-exposure scenarios in a number of industries. While construction is not a principal industry, workers do have recourse to its provisions for preventing harmful infections during the course of work.
Warning Signs
-
Biohazards on construction sites are indicated through signs called placards. These placards are commercially produced for industry professionals and relay information, codes and warnings specific to the substance in question. Placards are used not only on-site, but on the vehicles charged with transporting hazardous materials between facilities.
