burn. If one element of the fire triangle is not present or removed, fire will not start or, if already burning, will extinguish. Ignition sources can include any material, equipment or operation that emits a spark or flame—including obvious items, such as torches, as well as less obvious items, such as static electricity and grinding operations.
รายละเอียดเพิ่มเติมThis can kindle a fire even at a large distance from the welding station. This is a danger especially at work stations with cracks, chinks or openings. Here sparks can penetrate cavities or adjacent areas. Depending on the work process, the spark build-up can differ: With gas and arc welding, sparks can fly up to 7.5 metres far and 4 metres high.
รายละเอียดเพิ่มเติมThe Swedish FireSteel fire starter is composed of two basic parts – the rod and the striker. The rod is made from a high-quality pyrophoric alloy containing metals that include iron, magnesium, lanthanum and cerium.

รายละเอียดเพิ่มเติมThe most catastrophic disaster that can occur is an explosion. Unfortunately, oil platforms have a high-risk of fire or explosion—even though water surrounds them. Between the high use of electricity and fuel to run the different machinery, a tiny spark could have a devastating consequence for the workers on board.
รายละเอียดเพิ่มเติมAccording to the American Welding Society (AWS) Fact Sheet, Fire and Explosion Prevention, sparks can travel up to 35 ft. (10 m) horizontally and even farther when falling. They can pass through or become lodged in cracks, clothing, pipe holes, and other small openings. Even at 35 ft., sparks can be hotter than 2,500 degrees F.

รายละเอียดเพิ่มเติมThe spark erosion machining process, also known as spark machining, spark eroding, is a well-known nonconventional machining method to obtain geometrically complex features on any hard but electrically conducting materials using electrical discharges [1].Since electrical discharges are the primary cause of a desirable erosion of the workpiece and nondesirable depletion of the …
รายละเอียดเพิ่มเติมSmall embers can also be carried by the wind at speeds up to 30km/h. At this speed, these embers can be very dangerous as they can ignite fresh fuel and start additional fires ahead of the main fire. This is called spotting and is a major cause of homes and property being lost. The embers are usually carried on fine fuels such as leaves and sticks.
รายละเอียดเพิ่มเติมTransmission fluid can catch fire at or above 300 degrees, as that is the estimated flashpoint. When a liquid is heated up to or above its flashpoint, that means that it is releasing enough vapors to catch fire. But for this to happen a spark or other ignition source must be present.
รายละเอียดเพิ่มเติมEven something like dry coffee creamer can explode under the right conditions. So when Flicker opened the door to go into that dust collection room, it allowed air to stir up fine particles of rubber.
รายละเอียดเพิ่มเติมSparks from grinding and welding, for example, might be over 2000˚ C – under the right conditions (say one were to fall into a crack or tiny hole) this might stay hot enough to cause a fire for a half day (longer under some circumstances). Does this mean that you have to keep watch for a half day every time you do any grinding, cutting, or welding?
รายละเอียดเพิ่มเติมfor aluminium the melting point is much lower only approx. 600 degrees celsius so the sparks won't fly around like metal but actually adheres to the grinding disk so you won't see anything flying and will be harder and harder to cut as the disk will be filled more and more with molten aluminium, to prevent this people use candle wax so the …

รายละเอียดเพิ่มเติมBut a worn-out spark plug may be responsible for this issue in some cases. A spark plug is made up of materials that work together to produce a spark hot enough to cause an ignition in the air-fuel mixture. The efficiency of the spark plug is reduced when those materials wear out. This can considerably reduce the vehicle acceleration.

รายละเอียดเพิ่มเติมIf you can create a small enough particle of fresh iron, upon contact with oxygen in the air the iron particles increased surface area will oxidize faster than it can dissipate the heat formed during the reaction. The result: the particle of iron spontaneously becomes so hot that it glows as it oxidizes – and can be used to catch tinder on fire.
