Why is it necessary to use gloves during liquid penetrant testing?

Using gloves during liquid penetrant testing is essential primarily to prevent chemical exposure. The materials used in penetrant testing, such as the penetrant and developer, may contain hazardous substances that can be harmful if they come into contact with the skin. Wearing gloves minimizes the risk of skin irritation, allergic reactions, or other adverse health effects caused by these chemicals.

While improving grip, enhancing the sensitivity of the test, and maintaining cleanliness are also important factors in testing processes, the foremost reason for wearing gloves is the protection they provide against potentially dangerous chemical exposure. Overall, ensuring safety while handling chemical agents is a critical concern in nondestructive testing practices.
