Precaution while using LPG
Roughly half the LPG people use is consumed in homes for heating and cooking (in other words, instead of piped natural gas). Typically, this kind of LPG is delivered by road to a large tank placed safely outside a home or other building (for safety reasons). Its also possible to buy reusable gas canisters (from such companies as Calor in the UK) for powering standalone stoves, heaters, barbecues, and outdoor patio heaters (now frowned upon because of the energy they waste to the open air). Tiny LPG canisters are also widely used in portable haircare appliances, such as haircurling tongs.
