What is the maximum voltage allowed for corded electrical equipment inside a class A chamber?

  1. 240 volts

  2. 120 volts

  3. 60 volts

  4. 30 volts

The correct answer is: 120 volts

The maximum voltage allowed for corded electrical equipment inside a class A hyperbaric chamber is set at 120 volts. This limitation is primarily established to ensure the safety of patients and staff within the chamber. High voltages can pose significant risks of electrical shock, especially in an environment where the atmosphere and pressure conditions are different from standard conditions. Using equipment with a voltage higher than 120 volts increases the likelihood of electrical hazards, which is why hyperbaric facilities adhere strictly to this guideline. The use of lower voltage equipment minimizes these risks while still providing adequate power for necessary devices. The other voltages presented in the options either exceed the safety standard established for such environments or do not provide sufficient power for typical corded equipment used in hyperbaric medicine.
