The most effective method to prevent industrial dermatitis is by implementing substitution. Substitution involves replacing hazardous substances with less harmful ones, thus minimizing exposure right from the source. This proactive approach significantly reduces the risk of skin irritation or allergic reactions caused by exposure to hazardous materials.

Following substitution, using gloves is effective in providing a barrier between the skin and the potential irritants or allergens. Properly chosen and fitted gloves can offer substantial protection, preventing direct contact with harmful substances.

Lastly, the use of barrier creams can offer additional protection by creating a film on the skin that repels irritants. However, it is crucial to understand that barrier creams should not be relied upon as the primary form of protection, but rather as a supplementary measure.

Thus, the correct ordering from most to least effective in preventing industrial dermatitis is substitution, gloves, and barrier cream. This progression emphasizes the importance of addressing hazards at the source and using personal protective equipment as necessary.
