Rescuer Deaths

On February 9, 1911, E. A. Sutton, assistant superintendent of the Cokedale mine of the Carbon Coal & Coke Company, Carbondale, Colorado, lost his life while wearing a Draeger helmet-type oxygen breathing apparatus after an explosion in this mine in which 17 men were killed.  It is believed that this was the first instance in the United States, wherein a person died while wearing oxygen breathing apparatus.

This company was one of the first in Colorado to install oxygen breathing apparatus, but only three apparatus were purchased and available at the time of the explosion.  Sutton had worn the apparatus on only two previous occasions, for periods of one-half hour each, and therefore was not thoroughly familiar with its operation.

Sutton and a superintendent from a neighboring mine each put on an apparatus and left the third at the fresh-air base in reserve.  When they had traveled a considerable distance from the fresh-air base, his companion, who was traveling about 150 feet behind Mr. Sutton, saw him struggle with his apparatus and suddenly fall.  The companion immediately returned to fresh air for help.

After considerable delay, two workmen volunteered to go after Sutton without the aid of respiratory protection.  When they reached a point within about 100 yards of where he was lying, one collapsed and the other returned to fresh air.

Thirty minutes thereafter additional apparatus crews arrived and recovered the bodies of Sutton and the workman.  They were treated with a pulmotor for more than an hour, but neither could be revived.

Examination of Sutton's apparatus revealed that one of the potash cartridges had not been connected at the bottom.  This permitted the injector to pull in outside air, which presumably contained carbon monoxide.

15 Entombed in Model Mine
Colorado Springs Gazette, Colorado
February 10, 1911

Trinidad, Feb. 9. -- Fifteen miners are entombed and may be dead as the result of an explosion in the Cokedale mine of the Carbon Coal and Coke Company, eight miles west of Trinidad tonight.  Seventeen men were in the mine but two shot firers escaped two hours after the explosion.

The force of the explosion was distinctly felt at Trinidad, and seems to have been greatest in the main slope.  Timbers were blown 200 feet from the mouth of the slope, but the explosion seems to have been attended by no serious falls of rocks.  The explosion wrecked the fan house but the fan was uninjured and is still working although the air has been "short circuited" by the blowing out of brattices and doors.

Twenty rescuers are working desperately to reach the more remote parts of the mine where the 15 men are supposed to have been working.

The rescue work is under direction of E. F. Layliss, general superintendent, and E. A. Sutton, assistant superintendent, who led the first party into the wrecked workings.  The rescue party has penetrated 2,000 feet along the main slope.  At that distance black damp was encountered and helmet men are now making their way through the poisonous gas, bratticing the entries as they advance.

Trained rescue men are being rushed to Cokedale from all over the district.  The government mine rescue car in charge of J. C. Roberts, which was at Berwind, has been summoned, and the rescue car of the Colorado Fuel and Iron Company is on the way to the wrecked mine.

There are five exits from the Cokedale mine, and none but the main slope was injured.  It is hoped some of the men in the mine may make their way from one of these exits.

The two shot firers who escaped were working near the surface in No. 5 entry, and while both were overcome with gas, they were able to go to their homes without assistance.

There were no harrowing scenes around the pit mouth tonight such as have been common at other coal mine disasters.  The miners on the surface are thoroughly organized and the majority are engaged in carrying supplies to the rescue party.

The cause of the explosion is unknown, but it seems most improbable that it could have been an explosion of dust.  Precautions against the accumulation of dust were most strictly enforced at Cokedale.  The mine was furnished with water pipes throughout and a force of men was employed constantly in sprinkling and removing dust.

The Cokedale mine has been operated for four years and the camp was known as the model coal camp of America.  The property is owned by the American Smelting and Refining company and supplies the Guggenheim smelters.  It is said that more money has been expended in equipping the mine with safety appliances and modern equipment than at any coal mine in America.
