True. Permit required confined spaces contain or have the potential to contain a hazardous atmosphere.
Step-by-step explanation:
True. Permit required confined spaces are those spaces that contain or have the potential to contain a hazardous atmosphere.
A hazardous atmosphere refers to an atmosphere that may expose workers to the risk of death, incapacitation, impairment of ability to self-rescue, injury, or acute illness due to the presence of flammable gases, vapors, or dust, or the lack of sufficient oxygen.
For example, a permit required confined space may include a tank that previously contained toxic chemicals, a sewer, or a storage tank containing combustible gases.
