WOSSA Safety Training Videos

  


  


  

In a deliberate effort to raise awareness and reduce workplace injuries related to Pathogen Exposure, Confined Space Entry and the OSHA Construction Focus Four; Falls, Caught-in,-by, Struck by and Electrocution, WOSSA has developed new training resources that focus on workers in the On-Site industry. This training delivers both knowledge and practical skills to address the numerous hazards that are unique to our industry.

These videos were developed by WOSSA as an integral part of these safety training classes.
