How should flammable gas fires NOT be ignited?

Flammable gas fires should not be ignited manually due to the inherent risks and dangers associated with introducing an open flame or spark to a flammable gas environment. Manual ignition can lead to uncontrolled combustion, explosions, or fires that could result in severe injuries or property damage.

When dealing with flammable gases, safety measures and appropriate protocols are paramount. Other ignition methods, such as automatic systems, are designed to enhance safety by controlling the conditions under which ignition occurs. These systems typically incorporate safety mechanisms that minimize the risk of uncontrolled ignition.

Inductive ignition methods generally use electromagnetic fields to ignite gases without direct contact, further emphasizing safety and minimizing risks associated with manual ignition techniques. Using a fire extinguisher is identified as a method of suppression rather than ignition. Hence, manual ignition is considered the least safe option in this context.
