Soldering risks What I now wish to make clear is that, while a very great risk occurs should a flame or spark reach a gas-filled container, it is almost equally risky to use a soldering iron. The heat it passes to a container can be quite enough to cause gas to be generated and build up, and a tiny spark from metal friction can cause ignition. Therefore all junior tradesmen should have it impressed upon them that the same precautions are called for with a soldering iron as with gas torch or blow lamp, despite the fact that there will be no spark from the iron, only heat. The point to remember is that heat forms the main risk, although nothing will happen until the proportions of gas and air reach the explosion range.
Another aspect that can be misleading is
The January 15 issue of Commercial Motor will be a much-enlarged special number, devoted mainly to a wide-ranging survey of goods bodywork applications. Among the special features in this issue will be • How to guard against test-station failure through body defects.
• New capacity on tap, by lengthening trailer vans.
• Future prospects for glassfibre as a .commercial vehicle material.
• Insulation pros and cons—slab or foam?
• Furniture pantechnicon design trends.
• Essentials in modern meat-carrying bodywork.
• Solving other people's problems: a consultancy view.
• Pallet bodies are a growing trend for removals.
• Practical points on side-closures for vans.
