Blow torches can be used for a number of different purposes, but they are very dangerous and should not be used by untrained operators. They can cause severe burns and even death. They should only be used by trained professionals for specific applications such as welding and metal cutting. They are not safe to use for hobby projects or household tasks like light bulb replacement. Please call a professional if you have questions about the safe use of a blow torch.
