Chemical Protective Clothing - Glove Selection

Introduction to Chemical Protective Clothing

• PPE is the least effective control method.
• Considered a last line of defense.
• SDS should specify appropriate protective materials.
• Impervious gloves are not entirely impervious indefinitely.

Permeation Rate, Breakthrough Time, and Degradation

• Permeation Rate: Speed of chemical movement through material.
• Breakthrough Time: Duration before chemical penetrates glove.
• Degradation: Physical deterioration due to chemical contact.

Choosing the Right Material

• Describe the task accurately.
• Identify hazards: chemical, physical, biological.
• Consider flexibility and touch sensitivity.
• Determine contact type and duration.
• Consider skin exposure effects.
• Evaluate protective clothing hazards.
• Plan decontamination procedures.
• Provide education and training.

Examples of Skin Protection Selection

• Abrasion, sharp edges, chemicals, cold, heat, radiation.
• Materials vary based on hazard severity.
  • E.g., for severe abrasion: reinforced heavy rubber.
• Consult with suppliers for specific protective materials.

Points on Skin and Hand Protection

• Use appropriate protection matching job requirements.
• Follow care instructions.
• Be aware of material allergies.
• Ensure proper fit and coverage.
• Do not use damaged gloves.
• Clean and inspect gloves regularly.
• Know proper glove removal and disposal techniques.

Testing Gloves for Holes or Leaks

• Visual inspection and air inflation methods.
• Use compressed air jig for mass testing.

Workplace Evaluation

• Test gloves in actual job conditions.
• Lab tests may be needed for unknown permeation times.
• Manufacturers might conduct tests for customers.

PPE Program Requirement

• Competent review process required.
• Comprehensive PPE program includes training and maintenance.
• Regularly update program for chemical changes.

Information Sources for Material Selection

• Manufacturers provide selection information.
• Glove-material compatibility charts available.
• Testing for solvent mixtures if no data is present.
• Refer to Chemical Profiles for more info.
