A high-resistance connection (HRC) is a hazard that results from loose or poor connections in traditional electrical accessories and switchgear which can cause heat to develop, capable of starting a fire. [1] Glowing connections occur when relatively high current exists in a relatively large resistance object. Heat comes from power dissipation ...
The Dakota fire pit is an efficient, simple fire design that produces little to no smoke. [1] Two small holes are dug in the ground: one for the firewood and the other to provide a draft of air. Small twigs are packed into the fire hole and readily combustible material is set on top and lit.
An alternative to the pilot light is a system to create a high voltage electrical arc or spark between two electrodes, in order to light the gas flowing to the burner. Fail-safe design for such a system requires the burner flame to be detected by passing an electric current through the flame, which is received by the flame rectification circuit ...
Soon after pit stops second place Villeneuve reported braking problems, which was later diagnosed as a boiling problem on a very warm and humid day. Rookie Andre Ribeiro was soon very warm when he brought the Tasman car into the pits unscheduled; a fire developed in the rear of the car when the fuel vent stack stuck open allowing fuel to gush ...
The process of pit nucleation is initiated by the depassivation of the protective oxide layer isolating the metal substrate from the aggressive solution. The depassivation of the protective oxide layer is the less properly understood step in pitting corrosion and its very local and random appearance probably its most enigmatic characteristic.
Flare stack at the Shell Haven refinery in England. A gas flare, alternatively known as a flare stack, flare boom, ground flare, or flare pit, is a gas combustion device used in places such as petroleum refineries, chemical plants and natural gas processing plants, oil or gas extraction sites having oil wells, gas wells, offshore oil and gas rigs and landfills.
Ash pit. An ash pit is a remnant of a wildfire. It is a hole in the ground filled with ash, possibly containing hot embers beneath. It is one of the many hazards faced by those fighting wildfires. It is also a danger to residents and their pets returning after a wildfire has gone out. [1] [2]
Many modern fire alarm pull stations are single-action and only require the user to pull down a handle to sound the alarm. Other fire alarm pull stations are dual-action, and as such require the user to perform a second task before pulling down, such as lifting or pushing in a panel on the station or breaking a glass panel with an attached hammer.
