Hazards of low oxygen inside confined spaces

I got this information from a safety officer of a large company that happened in his company 20 years ago. A vessel had to have its rubber lining repaired. The adhesive used for holding the lining to the solvent was expensive and the contract labourers who were handling it were told to handle it carefully and not to spill it. However, when one contract labourer was entering the vessel by a ladder, he inadvertently lost grip on the open can of adhesive and it fell down to the floor of the vessel. In order to cover up his mistake, he and another co-worker entered the vessel quickly and tried to apply the adhesive to the walls of the vessel. Due to the sudden increase in adhesive concentration in the confined space, the oxygen level decreased and both died of asphyxiation.
Today there are accidents that still continue to happen on the above lines. Learn from history. Do not allow more people to die.
