Frequently Asked Questions
Q. Why should I avoid using nails, awls, or hammers to puncture gas canisters?
A. Striking metal nails with a hammer creates friction sparks. If sparks ignite residual flammable butane vapors inside, it can cause an instant explosion. Always use dedicated handheld safe gas puncturing tools or pliers without striking impacts.
Q. Can I throw away aerosol spray cans if they are still partially full of insecticide or paint?
A. No. Pressurized cans will burst inside sanitation compactor trucks, causing fires and injuries. Spray out the remaining contents completely into old newspaper or cardboard boxes outdoors, then puncture the empty metal can and recycle with metal cans.
