Exempel på hur man kan använda FIREDAMP i en mening

• It was created for use in coal mines, to reduce the danger of explosions due to the presence of methane and other flammable gases, called firedamp or minedamp.
• The coal used in Maine was bituminous, which is known for releasing firedamp, a mixture of gases composed primarily of flammable methane that is prone to spontaneous explosions.
• As well as firedamp, other damps include blackdamp (nonbreathable mixture of carbon dioxide, water vapour and other gases); whitedamp (carbon monoxide and other gases produced by combustion); poisonous, explosive stinkdamp (hydrogen sulfide), with its characteristic rotten-egg odour; and the insidiously lethal afterdamp (carbon monoxide and other gases) which are produced following explosions of firedamp or coal dust.
• When a bord had been worked out it was simply sealed off, but this meant that any firedamp accumulating there was not promptly removed.
• Mining accidents can occur from a variety of causes, including leaks of poisonous gases such as hydrogen sulfide or explosive natural gases, especially firedamp or methane, dust explosions, collapsing of mine stopes, mining-induced seismicity, flooding, or general mechanical errors from improperly used or malfunctioning mining equipment (such as safety lamps or electrical equipment).
• Early reports blamed a sudden inrush of firedamp from old workings which pitmen had inadvertently broken into.
• To guard against the possibility of a flame travelling back through the incoming gases (an explosive backblast), air ingress was by a number of small-bore tubes through which the ingress air flowed at a higher velocity than the velocity of a flame fueled by a mixture of firedamp (mostly methane) and air.
• When they came into regular use, barometers were used to tell if atmospheric pressure was low, which could lead to more firedamp seeping out of the coal seams into the mine galleries.
• On 1 October 1895 five men including the colliery manager and undermanager died at Shakerley Colliery after an explosion of firedamp.
• Hodgson then proceeded to assume that the "choak-damp" (perhaps afterdamp rather than blackdamp) pressing upwards from the seat of the explosion forced a pocket of firedamp to where the coal was burning and set off the second explosion.
• Mine rescue teams are trained in first aid, the use of a variety of tools, and the operation of self-contained breathing apparatus (SCBA) to work in passages filled with mine gases such as firedamp, afterdamp, chokedamp, and sometimes shallow submersion.
• Spedding improved this by ensuring that after ventilating areas currently being worked the exhaust stream was routed through previously worked areas to eliminate any possibility of firedamp accumulation in unventilated volumes.
• 15 July – an underground firedamp explosion at Risca Colliery in the Crosskeys district of Monmouthshire kills 120 coal miners and 69 horses.
• Then on 1 October 1895 five men including the colliery manager and undermanager died at Shakerley Colliery after an explosion of firedamp.
• Oxyde de carbone, alcool éthylique et grisou, 1903 – Carbon monoxide, ethyl alcohol and firedamp.
• The Union mine proved to be gassy and ignitions of firedamp were caused by sparks made when mechanised cutter picks hit coal balls containing nodules of iron pyrites.
• The seams worked at Hapton Valley were "gassy", with very high levels of firedamp recorded at the face.
• There have been three probable fires of the fire ignition of firedamp or other inflammable gas to contract with naked flame, ignition of coal dust by flame due to overcharged shot or ignition of inflammable gases produced and subsequently ignited by active mine fires.
• The film shows the hard and dangerous job a coal miner is forced to do, painfully earning his life and that of his family, lost, half of his miserable existence, in the depths of the earth, exposed to the terrible disasters produced by the fulgurating explosions of firedamp, the sudden irruption of water that invades the shafts and galleries, ripping open the walls of the mine, tearing away the woodwork in its irresistible rush.
