WELDING SCREEN SAFETY: COMPLETE GUIDE FOR SOUTH AFRICAN WORKSHOPS

Welding produces intense UV radiation, infrared radiation, and visible light that can cause permanent eye damage to anyone in the vicinity — not just the welder. South African occupational health regulations require adequate protection for all workers in welding areas. This guide covers everything you need to know.

Types of Welding Screens

Yellow Translucent PVC Screens

The most common type. Yellow PVC filters UV and arc flash radiation while allowing some light transmission. Workers can see movement through the screen without being exposed to harmful radiation. Suitable for MIG, TIG, and general arc welding.

Flame-Retardant PVC Curtains

Used where there is a higher risk of fire from welding sparks. These curtains are treated to resist ignition and slow the spread of flame. Required in most manufacturing environments under South African fire regulations.

Installation Requirements

• Screens must fully enclose the welding zone with no gaps at floor level
• Height should be a minimum of 2 metres to prevent radiation spill
• Panels must overlap by at least 100mm at joins
• Floor-mounted or suspended systems must be stable and not move during normal workshop activity

Maintenance and Replacement

Welding screens degrade over time as UV exposure causes yellowing and reduced radiation filtering. Inspect screens every 6 months:

• Replace panels that have become cloudy, brittle, or cracked
• Check suspension hardware and frames for stability
• Clean with mild soap and water — avoid solvents

Compliance in South Africa

The Occupational Health and Safety Act (OHSA) requires employers to protect workers from welding radiation. The relevant standard is SANS 10083. Non-compliance can result in fines and liability in the event of injury.
