I read on news online that there has been a lot of gas explosions of some kind, It made me think about the safety of the propane gas cylinders. I always make sure the room is ventilated and I keep it in the shed at night. Is there a lot of safety issues with this cylinder? I haven't put any attachments on it, I have the Sievert beginners torch kit. Should I put a safety cut-off valve on it? I have posted before about this a while ago but I can't find my post! I am a little nervous using it... Thank you! I could do with some advice as I can't ask my teacher or DIY guy etc due to lockdown
