Confined Spaces - Air Monitoring and Ventilation Considerations and Best Practices

OSHA continues to report asphyxiation as the leading cause of death in confined spaces, generally resulting from oxygen deficiency or from exposure to toxic atmospheres. One of the most tragic incidents that may come to mind is the loss of the three utility-company workers who succumbed to toxic gases in a manhole back in early 2017. OSHA investigated that incident and the post-incident testing revealed lethal levels of hydrogen sulfide and carbon monoxide. The employer was cited by OSHA for “serious violations of failing to purge or ventilate the confined space before entry, exposing their workers to an asphyxiation hazard, and not providing the necessary rescue and emergency equipment” for a permit-required confined space. Had testing and monitoring with a gas detector been in use, an alarm would have indicated danger and these three lives could have been saved.

In this webinar, we will discuss best practices and procedures for air monitoring in a confined space; features and functions of multi-gas monitors to perform atmospheric testing prior to and during entry; and ventilation considerations and best practices.  

During this webinar, you will learn:

  1. The types of air monitoring that should be done before entering a confined space and continuously during entry 
  2. Types of gas detectors and how to select the right equipment
  3. The types of ventilation and ventilation requirements for confined spaces
