Fire and Explosion Protection During Welding
Fire and explosion protection during welding prevents fires caused by sparks, hot slag, or heat conduction. A fire watch and the removal of combustible materials are essential.
Physical-Chemical Mechanism of Action
Sparks and hot slag can quickly ignite combustible materials, especially in atmospheric conditions with low humidity. Heat conduction can also spread fire through metal conductors to other areas.
Metallurgical Relevance & Welding Risks
Incorrect safety measures can lead to severe fire and explosion damage, including injuries to personnel and damage to machines and buildings. There is also a risk of a full fire outbreak in fire-prone areas.
Workshop Practice & Action Guidelines
1. Set up a fire watch: Have a fire watch immediately at the welding site and perform regular checks.
2. Remove combustible materials: Remove all combustible materials like paper, plastics, and oils from the welding area.
3. Wear protective clothing: Wear protective clothing with shielded hands and face protection.
4. Maintain safe distance: Keep a safe distance from combustible materials and other welding points.
5. Take spark protection measures: Use spark-resistant clothing or a welding helmet with built-in spark protection to block sparks.
