Health & Safety tips:
Exposure to freshly treated timber should be avoided and should only be supplied once the chemicals have been allowed to permanently fix into the wood.
Always wear a filter mask and eye protection when machining, sanding or docking treated pine.
Wear gloves at all times.
If sawdust comes into contact with skin, wash immediately.作者: Feature 时间: 2011-8-31 01:05:44
