What is a safety lamp?
The safety lamp is a lamp that has been designed for safe use in areas where flammable gases and particles are present. This device was originally developed for use in mines, although it can be used in other environments. The earliest safety lamps used flames, while modern lamps are usually electric. Numer examples of antique safety lamps can be seen on the display in museums, including versions designed by the first pioneers in this area, such as Sir Humphry crowds.
mining has always been dangerous to work with a number of challenges, one of which provides adequate lighting. Dimat conditions in the mines can lead to miners' problems for eye problems, except that they make it difficult, and early mines have used various lighting tools. Most of these tools included open flames of some kind or partially protected flames that represented a serious safety risk in the mine because the release of flammable gases around the open flame can causeexplosion. Therefore, a security lamp is needed.
The safety lamp is designed to avoid explosion when flammable materials are present. The heat of the lamp is carefully distributed and the flame itself is protected so that the temperatures cannot increase high enough for gases and materials such as coal to ignite. In the case of a lamp that does not rely on an open flame, such as an electric lamp, electric components are protected to prevent sparks, and the heat of the lamps is dispersed so that it does not accumulate dangerously hot. Historically, safety lamps were hung along the snake mine; Today, most are electrified by their own safety lighting systems and miners wear safety lamps on the helmets.
Safety lamp with flame, however, does not only provide a source of lighting. It also acts as a form of alarm because the nature of the flame changes as the composition of gases in SURChanges of air air. Lack of oxygen would cause flame spraying and sent the signal to the miners to get out before they suffocate. Flammable gases can cause growth or change of colors, indicating that a dangerous situation has occurred and the mine should be evacuated until the gases are safely venting.
Today, miners rely on the field of sensors to alert them when the mixture of gases underground becomes dangerous rather than a safety lamp. These sensors sound hearing alarms in addition to generating a visual alarm, making it easier to react miners. Safety lamps worn by miners are used only as a source of lighting, with shielded electric components that ensure that the spark does not appear to light the gases in the mine.
