Recognizing hazards to avoid accidents
Researchers at the National Institute for Occupational Safety & Health (NIOSH) are studying how workers in the stone, sand and gravel industry search for and find hazards in their work environment. Data collection is currently underway. Mine workers, safety professionals and mining students are visiting the Pittsburgh research laboratory and viewing panoramic images of the pit, plant, shop and roadway at a surface stone mine. Participants are asked to identify hazards in these images while researchers track where and how they are looking. Participants then sit down with researchers and discuss the hazards they identified and/or missed. The group’s initial data analyses from the Virtual Immersive Simulation Laboratory (VISLab) research show several interesting results. First, mine workers are generally more knowledgeable about hazards that occur at their typical work location. For instance, front-end loader and haul truck operators who spend a majority of their days loading in the pit are able to correctly identify more highwall and loading hazards than workers who spend time at other locations at the mine… Keep Reading

Choosing a portable asphalt recycling plant
Sean Donaghy of IRock Crushers answers questions about the selection and use of portable asphalt recycling plants. Q: When selecting a portable asphalt recycling plant, what are the most important items to consider? A: It’s critical for aggregate producers and crushing contractors to consider portability and the time involved in setting up the asphalt recycling plant. Some plants are very labor intensive and take days to set up, but with fully hydraulic models, it may only take about an hour. This is because hydraulic systems help reduce the need for producers to use cranes for moving equipment into place. And closed-circuit plants require minimal setup times to keep an operation productive and profitable. Producers know they need to consider Department of Transportation regulations when considering a piece of equipment, especially portable asphalt recycling plants. Due to the weight of portable units, users transport the hopper feeder separately to meet weight regulations, which requires additional lifting and transporting equipment. Aggregate producers and crushing contractors also need to consider the desired production… Keep Reading
