6.3.2 Eye and Skin Irritation Explained

Key Concepts of Eye and Skin Irritation

1. Causes of Eye and Skin Irritation

Eye and skin irritation in welding are primarily caused by exposure to ultraviolet (UV) radiation, infrared (IR) radiation, sparks, and chemical contaminants. UV radiation from the welding arc can cause arc eye (welder's flash), while sparks and hot metal can lead to burns and abrasions.

2. Symptoms of Eye Irritation

Common symptoms of eye irritation include:

• Pain and discomfort in the eyes
• Redness and inflammation
• Watering or excessive tearing
• Blurred vision
• Sensitivity to light (photophobia)

3. Symptoms of Skin Irritation

Common symptoms of skin irritation include:

• Redness and inflammation
• Burns and blisters
• Dryness and flakiness
• Rashes and itching
• Chemical burns from contact with welding chemicals

4. Prevention Measures

To prevent eye and skin irritation, consider the following measures:

• Use Proper PPE: Wear a welding helmet with the appropriate shade lens, safety goggles, and flame-resistant clothing to protect against UV and IR radiation, sparks, and hot metal.
• Maintain Good Ventilation: Ensure proper ventilation and fume extraction to reduce exposure to chemical contaminants.
• Regular Breaks: Take regular breaks to allow your eyes and skin to recover from exposure.
• Hydration and Moisturization: Stay hydrated and use moisturizers to keep the skin healthy and resilient.

5. First Aid for Eye and Skin Irritation

Immediate first aid for eye irritation includes:

• Rinse the eyes with clean water for at least 15 minutes.
• Avoid rubbing the eyes to prevent further damage.
• Seek medical attention if symptoms persist.

Immediate first aid for skin irritation includes:

• Rinse the affected area with cool water for at least 15 minutes.
• Apply a soothing cream or aloe vera gel to reduce inflammation.
• Seek medical attention for severe burns or chemical exposure.

Examples and Analogies

Imagine eye irritation as getting sand in your eyes. Just as sand causes discomfort and redness, UV radiation from welding can irritate the eyes and lead to arc eye.

Think of skin irritation as sunburn. Just as prolonged exposure to the sun can cause redness and pain, prolonged exposure to welding sparks and radiation can lead to burns and inflammation.

Conclusion

Understanding the causes, symptoms, and prevention measures for eye and skin irritation is crucial for welders to maintain their health and safety. By using proper Personal Protective Equipment (PPE), maintaining good ventilation, and taking appropriate first aid measures, welders can minimize the risk of eye and skin irritation and ensure a safer working environment.
