Why 24 volt lamp use in confined space entry job?

Question

Accepted Answer

24 volt lamps are used in confined space entry jobs for safety reasons.

24 volt lamps are considered intrinsically safe as they do not produce sparks that could ignite flammable gases or vapors in confined spaces.
They are also less likely to cause eye damage or blindness in case of accidental exposure.
The low voltage also reduces the risk of electrical shock.
Examples of confined spaces where 24 volt lamps are used include tanks, vessels, and pipelines.
In addition, 24 volt lamps are often used in conjunction with explosion-proof equipment to further reduce the risk of ignition.
