I had been on board this vessel only a few minutes previous to this explosion and at that time everything was in proper order, but I had left to keep an appointment with the Minister of Marine. Before reaching his office, however, one of our office men overtook me and notified me of the explosion. On my return I found great excitement, as it was reported that many men had been killed. The explosion had set fire to a lot of shavings and the wooden deck covering over the batteries, as well as some joiner work which was in process of erection. Some of the yard officers had ordered the hatches battened down, but the engines were still running, receiving sufficient air through ventilators to supply combustion. It was reported that several men were missing, and it was believed they had been killed by the explosion and were still on board. In the meantime the Minister of Marine and other officers had arrived, also a couple of fire companies, and I requested them to open the hatches and see if they could not put out the fire and get out the bodies if any were there. The officers objected on the ground that if any water were put on board it probably, upon coming in contact with the batteries, would create a lot of hydrogen gas and cause a further and perhaps more disastrous explosion. Finally I procured a couple of flasks of carbonic acid gas and let that into the boat over the battery compartment where the fire was, which smothered the flames, and then borrowed one of the firemen's smoke helmets and went down into the vessel, expecting to find some of the bodies of our missing men. The fire had burned the rubber insulators off the wires and some of the asphaltum insulators around the batteries, and the smoke was so thick that it was impossible to see anything, even with an electric lamp which I carried, but the heat was not very intense, as the flames had been put out by the carbonic gas and I found no bodies, so I ordered the hatches open, blowers put in, and a few buckets of water, which put out the embers. Our missing men were later found in the hospital, where they had been rushed before their names had been taken. Seventeen of the men were injured so badly that they had to go to the hospital, but the burns were mostly superficial, only the outer skin and hair being burned, and this was due to the instantaneous flash of the gasolene. They all eventually recovered.
