Why 24 volts light to be used in confined space?

Answer 1

It is to reduce the impact of electrical shock to the workers (in case any). By having less voltage the consequence would also be diminished. Installation with higher voltage (110 V, 220 V, or 380 V) is possible to create a fatal incident depending upon the environment (wet, metal surface, etc.)

Answer 2

A 24-volt light may be used in confined spaces because it produces less heat compared to higher voltage lights, reducing the risk of fire in a small enclosed area. Additionally, the lower voltage is safer for the user in case of accidental contact with the light fixture.

Answer 3

Other voltages are used in confined space applications. Depending on what the electrical reason power is needed in confined space different electrical equipment is used. In wet well applications explosion proof equipment is used and the voltages can go as high as 600 volts. Non explosion proof areas that are still confined space ordinary lighting can be used and low voltage applications do not apply.

Before entering any confined space an air sample must be taken.

Answer 4

24 volts is required because the higher volts is danger in any confined space because some flammable gas,vapors,mist may be still present in any confined space area.
