A miner's hard hat can be fitted with a small battery pack and a lamp that hooks to the front.
Inhalation hazards are among the most significant dangers for workers in mines. Gases can cause nausea or may even be toxic. Dust particles in the air can cause respiratory complications and more.
Minors often use respirators to reduce inhalation levels and work comfortably in the mine. The style of respirator varies based on the dangers associated with a particular mine. Many respirators are simple face masks with an odor filter and protection from airborne contaminants. Some are powered and provide a flow of fresh oxygen to the miner.
The days of taking a canary into the coal mine as a warning system of poisonous gases are long gone. Gas detection sensors are now placed in mines to monitor the levels of methane, carbon monoxide, oxygen, nitrogen dioxide and other gasses to ensure that the workers are...
