Radiation Hazards in Welding and Cutting
The Problem
Welding, torch cutting, and brazing generate intense radiation that can harm your eyes and skin if you’re not protected. Infrared, visible light, and ultraviolet radiation can cause serious health risks, like burns, blindness, and even long-term conditions like cataracts or skin cancer. Today, we’ll focus on identifying these hazards and understanding how to protect ourselves and others.
Identify the Hazards
- Visible Light Radiation:
- Hazard: Intense light causes temporary blind spots and can contribute to long-term vision problems, such as cataracts.
- Example: Staring at a welding arc for even a few seconds can cause eye strain or blindness.
- Infrared (IR) Radiation:
- Hazard: Felt as heat near welding or cutting operations, infrared radiation can burn your skin or eyes.
- Example: You may feel a burning sensation on unprotected skin after standing too close to a welding arc.
- Ultraviolet (UV) Radiation:
- Hazard: Invisible UV rays cause flash burns to your eyes (like "welder’s flash") and skin burns similar to sunburn. Prolonged exposure can increase skin cancer risks.
- Example: Flash burns occur when welding arcs are viewed without proper eye protection.
Safety Practices and Preventative Measures
- Wear the Right Personal Protective Equipment (PPE):
- Clothing: Use fire-resistant shirts, welding jackets, and long sleeves to protect your torso, arms, and neck.
- Gloves: Heavy-duty gloves with gauntlets protect your hands and wrists from UV exposure and burns.
- Face Shields and Hoods: Always use welding hoods or shields to protect your face and head.
- Use Proper Eye Protection:
- Welding Lenses: Choose safety glasses, goggles, or welding hoods with lenses that filter out harmful light.
- Selecting Lens Shades: Use the correct shade of filter lens based on the welding type. (Handouts or charts are available to guide lens selection.)
- Quality Lenses: Ensure lenses block harmful UV rays while allowing you to see your work clearly.
- Protect Others Nearby:
- PPE for Helpers and Bystanders: Anyone near welding operations must wear appropriate PPE to avoid accidental radiation exposure.
- Screens and Shields: Use welding screens or shields to block light radiation and protect nearby workers.
- General Safety Practices:
- Inspect PPE before starting work—report damaged equipment immediately.
- Shield the work area to prevent radiation from reaching others.
- Ask your supervisor if you’re unsure about proper equipment or procedures.
Real-Life Case or Scenario
A welder experienced severe flash burns to his eyes after forgetting to use his welding hood for a ‘quick tack weld.’ The intense UV radiation caused extreme pain and temporary blindness, leading to several days off work. This could have been avoided by wearing proper PPE, even for short welding tasks.
Employee Responsibilities
- Inspect and wear the appropriate PPE before every job.
- Ensure your welding lenses and shields are undamaged and of the correct shade.
- Protect others by using screens or ensuring bystanders wear PPE.
- Report any damaged equipment or PPE to your supervisor immediately.
Employer Responsibilities
- Provide fire-resistant clothing, appropriate welding shields, and correct safety glasses.
- Train workers on radiation hazards and proper PPE selection.
- Maintain equipment and ensure the work area is properly shielded.
Discussion & Questions
- "What’s the most important step you take to protect yourself from welding radiation?"
- "Have you or a coworker ever experienced flash burns or skin burns from welding? What caused it, and how could it have been prevented?"
Encourage employees to share their experiences and clarify any doubts.
Commitment/Action Plan
Let’s commit to always wearing the proper PPE during welding and ensuring our equipment is in good condition. If you notice damaged PPE or unsafe conditions, report it immediately so we can work safely.
Wrap-Up
Radiation hazards are serious but preventable. By understanding these risks and taking proper precautions, we can protect ourselves and our coworkers. Thank you for your attention—let’s keep safety our top priority.
Standards Overview
- OSHA Standard 1910.252 outlines safety requirements for welding and cutting operations, including protection from radiation hazards.
- Employers are required to ensure that workers use appropriate personal protective equipment (PPE) and safeguards to limit radiation exposure.
