What is the most effective control method for prevention of industrial dermatosis?

• A. Substitution followed by gloves and barrier cream
• B. PPE only
• C. Training only
• D. Ventilation improvements

Answer: (A)

This question tests the hierarchy of controls for preventing skin hazards like industrial dermatosis. The most effective approach is to remove or reduce the hazard at the source. Substituting a hazardous chemical or process with a less irritating or less sensitizing one directly lowers or eliminates skin contact, which has by far the biggest impact on preventing dermatitis. Protective measures like gloves and barrier creams are important as a secondary defense, but they don’t remove the hazard itself. Gloves can fail through tears, permeation, or improper use, and barrier creams may be ineffective on certain chemicals or damaged skin. Training helps, but it doesn’t prevent exposure if the hazard remains. Ventilation tackles airborne exposure, not dermal contact, and wouldn’t address skin hazards as effectively as substitution. So substituting the hazardous material or process first, followed by protective gloves and barrier creams, provides the strongest protection against industrial dermatosis.
