Yes, oxygen candles are a real thing. They are devices designed to generate oxygen for various purposes in situations where a portable and compact oxygen source is required. Oxygen candles have been used in various industries, including aerospace, military, and underwater diving.
Oxygen candles typically consist of a solid chemical compound, such as sodium chlorate, that releases oxygen when heated. The candles are ignited, and the heat generated causes the chemical compound to decompose, releasing oxygen gas as a result. The oxygen is then available for inhalation or other uses.
These candles have been used in environments where a reliable oxygen source is necessary, such as in submarines, spaceships, high-altitude aircraft, and confined spaces where ventilation is limited. They can also be utilized in emergency situations or as a backup oxygen source.
It's important to note that oxygen candles should be handled with caution and used according to specific guidelines provided by the manufacturer. Improper use or mishandling can lead to safety risks, such as fire hazards or oxygen enrichment, which can be dangerous. Therefore, it's essential to follow proper safety protocols and receive appropriate training when working with oxygen candles or any other oxygen-generating devices.
