OSHA News Release on Confined Space Rule
Manholes, crawl spaces, tanks and other confined spaces are not intended for continuous occupancy. They are also difficult to exit in an emergency. People working in confined spaces face life-threatening hazards including toxic substances, electrocutions, explosions and asphyxiation.
Last year, two workers were asphyxiated while repairing leaks in a manhole, the second when he went down to save the first — which is not uncommon in cases of asphyxiation in confined spaces.
"In the construction industry, entering confined spaces is often necessary, but fatalities like these don't have to happen," said Secretary of Labor Thomas E. Perez. "This new rule will significantly improve the safety of construction workers who enter confined spaces. In fact, we estimate that it will prevent about 780 serious injuries every year."
