Practically, this means that the carbon monoxide concentration in the airlock could possibly be many instances larger than 400, and consequently there can be insufficient purging capacity to scale back the level to 25 ppm for

Further,

>All concerned building employees had elevated blood ranges of carboxyhemoglobin indicating they had inhaled air containing high CO concentrations. Among those considerations have been the ability of the tested refuge alternatives to purge the interior environment of harmful carbon monoxide and the factors that might influence heat buildup in refuge options as soon as deployed and occupied by mine staff. It should be emphasised that the finding of the tested refuge alternative needing to be derated starting at mine ambient temperatures of 60°F applies solely to the examined tent-type refuge alternative
>There have been no carbon monoxide detectors in the constructing the place the incident occurred. A tent-kind and a inflexible steel mobile refuge alternative have been used to investigate the first query, with carbon monoxide used for tests involving simulated occupants and sulfur hexafluoride used for tests with reside occupants.
