EWT - Enclosed Spaces

Learning objectives

  • Accurately distinguish a 1910.269-governed "enclosed space" from a 1910.146-governed "confined space" with potential entry-permit requirements.
  • Select OSHA-mandated safe work practices for enclosed spaces, including: inspection/testing for hazards; rescue precautions; and prudent entry.
  • Select appropriate ventilation and/or monitoring practices to maintain a safe atmosphere in an enclosed space.

Course overview

This lesson covers: determining whether a restricted workspace qualifies as an "enclosed space," versus a "confined space" that is governed by the more stringent 29 CFR 1910.146 standard; testing, rescue, and safe work practices required for working in tight spaces; and methods for ventilating such spaces to prevent or clear unsafe atmospheres (meaning, gas mixes that are oxygen-deficient, oxygen-enriched, flammable, or toxic).
