This invention relates in general to the field of safety devices, and more particularly, but not by way of limitation, to systems and methods for providing advanced warning and risk evasion when hazardous conditions exist. In one embodiment, a vicinity monitoring unit is provided for monitoring, for example, oncoming traffic near a construction zone. In some embodiments, the vicinity monitoring unit may be mounted onto a construction vehicle to monitor nearby traffic and send a warning signal if hazardous conditions exist. In some embodiments, personnel tracking units may be worn by construction workers and the personnel tracking units may be in communication with the vicinity monitoring unit. In some embodiments, a base station is provided for monitoring activities taking place in or near a construction site including monitoring the locations of various personnel and vehicles within the construction site.

Advanced warning and risk evasion system and method

A method for using recycled lubricating oil as a fuel source includes receiving prepared recycled lubricating oil, filtering the recycled lubricating oil through a first filter. The recycled oil is pumped into the top of a first holding tank. The recycled oil is circulated from the bottom of the first holding tank through the first filter to the top of the first tank. The recycled oil is pumped from the bottom of the first holding tank through the first filter to the top of a second holding tank. The recycled oil may then be pumped or pulled through a second filter to a preheater to lower the viscosity of the recycled oil to a predetermined level. From the pre-heater the heated recycled oil may be fed to a burner for heat generation or may be fed back to a storage tank. The apparatus for using recycled lubricating oil as fuel includes a storage system having one or more holding tanks along with a filtration system having a first filter for initial contaminant removal. A pre-heater is also included to lower the viscosity of the recycled oil to make it easier to move. The filtration system may also include a second filter prior to preheating. A pump is included to recirculate the recycled oil to prevent water and sludge settling and to move the recycled oil from tank to tank and to a burner where it may be consumed and turned into heat energy.
