• Durability: Resistant materials extend the lifespan of goggles in harsh workshop conditions.

Cleaning and Maintenance of Goggles

• Regular cleaning: Use mild soap and water or approved lens cleaners to remove dust and smudges.
• Scratch prevention: Store goggles in protective cases to avoid lens damage.
• Inspection for damage: Check for cracks or loose parts before each use.
• Lens replacement: Replace scratched or damaged lenses promptly to maintain visibility.
• Hygienic practices: Share goggles only after proper disinfection to prevent eye infections.

Training and Compliance in Eye Protection

• Proper wearing techniques: Training ensures goggles are worn correctly and consistently.
• Awareness of hazards: Technicians must understand the risks that goggles mitigate.
• Enforcement of PPE policies: Supervisors in workshops should monitor compliance with eye protection rules.
• Incident reporting: Any eye injury or near-miss should be documented and analyzed to improve safety measures.
• Continuous improvement: Feedback from technicians can guide selection of more comfortable or effective goggles.

1.1.3 Dust Masks

Dust masks protect respiratory health by filtering airborne particles generated during glass cutting, sanding, or adhesive application. In Kenya’s urban workshops where ventilation may be limited, masks reduce inhalation of harmful dust and vapors.
