Q. What is required of an engineer or fireman in the care of a boiler?
A. He should watch carefully all the parts that are exposed to any steam and see that they do not become unduly weakened by corrosion or accident. All the working parts and fittings should be examined daily and be repaired or replaced as soon as they show signs of wear or weakness. The [steam gauge] and [safety valve] should receive constant care and both should be tested frequently, the one by the other, and the steam gauge by a standard in order that it may be known to be in perfect order. When scale forming water is used the feed pipe should be frequently uncoupled and examined and all sediment removed. The check valve should be examined frequently to see that it seats properly so that water cannot leak from boiler in this way and the utmost care should be taken in regard to the consumption of fuel.
Q. In case of accident how should an engineer conduct himself?
A. With the utmost coolness.
Q. If the water gauge glass breaks, what should be done?
A. The upper and lower gauge valves should be closed immediately.
Q. Can a new glass be put in at once?
A. No, because a new glass is cold, and if put in position and steam turned on, the sudden heat and expansion would be apt to crack it.
Q. When can a new glass be put in?
A. After the boiler has been cooled off.
