Highway construction workers

A highway construction worker drives an asphalt pavement roller. He works an 8-hour shift. If the machine vibrates the driver at 4 Hz and produces a seat accelera-...

The next time you drive by a highway work zone, try to envision how it differs from one that existed a decade ago. Is there more equipment on site Maybe. Are the barrels and barriers still orange Most likely. Are drivers still expected to slow down in these areas Absolutely. Perhaps the most obvious change is that you can see the workers. Today, high-visibility clothing on a highway construction worker is as ubiquitous as a stethoscope around a doctor s neck. 

Occupations and exposure to lead The following occupations can expose workers to lead ammunition manufacturers (guns and bullets), auto body repairs, auto radiator repair shops, battery workers, brass/copper foundries, bridge and highway construction, cable makers, gas stations, glass manufacturers. 

OSHA rules for heavy equipment, falls, power lines, electrical equipment, tools, excavations, carbon monoxide, and asphalt fiimes are covered throughout 29 CFR1926. OSHA rules for highway construction sites (also called work zones) can be found in 29 CFR 1926 Subpart G ( 1926.200 -. 203). Unfortrmately, OSHA does not provide much in the way of protecting workers from hazards of work zone traffic. However, while the Department of Transportation (DOT) has the intention of protecting motorists and pedestrians, it also provides some protection for road workers rmder 23 CFR 630 Subpart J and K and 23 CFR 655 Subpart F. 

Construction workers building Disney World experienced an epidemic of contact dermatitis from poison sumac [145]. Compositae dermatitis can also be seen in highway workers in this country, especially in main-... 

Whether use of high-visibility warning garments by construction workers in highway work zones is required — 1926, Subpart G — revised information, Aug. 5, 2009... 

Construction areas shall be posted with legible traffic signs at points of hazard (Figure 6-2). All traffic control signs or devices used for protection of construction workers shall conform to American National Standards Institute D6.1, Manual on Uniform Traffic Control Devices for Streets and Highways. 

These updates affect everyone from highway construction and maintenance crews to engineering personnel and survey crews who are all required to wear high-visibility apparel on the job. Depending on the environment, working conditions as well as state and local guidelines, road workers need to wear either Class 2 or Class 3 garments. 

Redox reactions play an important role in industrial safety. Explosives are used in controlled ways in the mining, highway, and construction industries. The use of explosives allows modern workers to break up bedrock and carry out necessary demolitions from a safe distance. Chemists are involved in the development and production of explosives. They are also involved in making recommendations for the safe handling and disposal of explosives. 

National Institute for Occupational Safety and Health (NIOSH) records indicate that between 1992 and 2005 falls to lower level, electrocution, highway incidents, and being struck by an object were the leading causes of death in construction. One-third of the fall-related deaths were falls from a roof, 18 percent were falls from scaffolding, and 16 percent were falls from ladders. Electrocutions accounted for 9 percent of the deaths in construction in 2005. The main cause of electrocution for electrical workers was direct contact with energized equipment and wiring, while over half the electrocutions of non-electrical workers were caused by contact with overhead power lines with objects including ladders, poles, and cranes.
