OMAHA, Neb. (AP) — A group of area firefighters will learn more about responding to incidents involving hazardous materials at workshops in Omaha this week.

The workshops sponsored by Union Pacific and BNSF railroads and the chemical industry will focus on dealing with chlorine emergencies but they will also offer general information about hazardous materials.

Between 40 and 50 people are expected to attend the trainings on Wednesday and Thursday.

Union Pacific spokesman Mark Davis says the first responders will have the chance to check out a railroad tank car and different tanks that might be used to store chlorine at a pool or water treatment plant.

These industry-sponsored trainings are staged across the country each year and often focus on a particular commodity. In recent years, crude oil and ethanol have been highlighted.
