Confined Space Knowledge Center

With approximately 1.6 million workers entering confined spaces each year, how to keep these workers safe is a topic worth discussing. In fact, OSHA estimates that employers fully complying with safety standards would prevent 53 deaths, 5,000 lost days, and 5,700 other accidents annually. Unfortunately, a NIOSH review determined that many injuries and fatalities related to confined spaces happened simply because employers and their workers failed to recognize, plan, and control for the hazards related to this type of work. With proper diligence, you can help your employees stay safe in these challenging conditions.
