Carbon monoxide (CO) is a deadly poisonous gas
Human senses to detect the presence of this gas is difficult because it is odorless and tasteless. Carbon monoxide is formed from incomplete combustion due to lack of oxygen.
In underground mines, this gas emissions arising from the disposal of equipment or gas-fueled fuel remaining after blasting. Carbon monoxide in large quantities will be produced when there is a fire underground.
Carbon monoxide is poisonous because of hemoglobin in the blood more easily tie this gas than oxygen. In one literature mentioned that the hemoglobin binds carbon monoxide 230 times more easily than oxygen.
As a result of the blood which was transporting CO, the oxygen supply to vital organs is reduced. One of the sensitive organ is the brain. Lack of oxygen to the brain can cause brain damage to lead to death.
Here are the symptoms of carbon monoxide poisoning in various concentrations:
* 35 ppm (0.0035%) Dizziness if exposed for more than 6 hours
* 100 ppm (0.01%) Dizziness when exposed to more than 2 hours
* 200 ppm (0.02%) Dizziness in the range of 2-3 hours
* 400 ppm (0.04%) Dizziness great in the range of 1-2 hours
* 1.600 ppm (0.16%) Dizziness in 45 minutes. Unconscious within 2 hours.
* 3.200 ppm (0.32%) Dizziness in the range of 5-10 minutes. Death in 30 minutes.
* 6.400 ppm (0.64%) Dizziness within 1-2 minutes. Mortality is less than 20 minutes.
* 12.800 ppm (1.28%) was realized within 2-3 breaths. Death in 3 minutes.
To protect underground miners from the risk of gas poisoning, they are equipped with a tool called a Self-Contained Self-Rescuer (SCSR). When activated, the tool is capable of providing oxygen while the worker is looking for a way out.
While in the mine, SCSR should not be separated from the workers. Usually this means dicantelkan at waist, side by side with the head lamp batteries.
SCSR addition, companies also obliged to provide refuge chamber (chamber evacuation). Refuge chamber shaped like a container that can accommodate a dozen to several dozen people.
This tool has a system of supplying oxygen and food reserves plus P3K, even the toilet. Workers who are trapped can take refuge there until rescuers arrived.
Measurements of carbon monoxide levels are also required after blasting. Measurements were taken to ensure further work can be done safely without the threat of poisoning.
