| Deaths were mainly caused by carbon monoxide poisoning, known as afterdamp. |
| They had managed to soak their shirts in water and breath through them to filter out the afterdamp. |
| As they had been almost completely destroyed it was impossible to enter owing to the afterdamp which prevailed. |
| These men had survived the force of the explosion, but had succumbed to the effects of the afterdamp. |
| Explosions made headlines, but falling rocks killed more miners, who could also be poisoned by underground gases, which they variously named stinkdamp, blackdamp, firedamp, and afterdamp. |
| The afterdamp and smoke passed directly to the airshaft from the split of the ventilating current in the section. |
