The plaintiff, while in the defendant’s employ as a stationary steam engineer, was injured by stepping into a pit in the floor of the engine room.
There were four engineers in all employed by the defendant, *93three of whom were known as “watch engineers,” the plaintiff being one of them, and one chief engineer. The plaintiff worked eight hours a day, seven days a week, and he worked on the night shift for two weeks at a time. At the time of the accident he was working on the night shift from eleven o’clock at night until seven o’clock in the morning. There were two pits under the floor in the engine room, opening into each of which was a trap door. These pits were constructed “to remove any waste water that came from the exhaust pipe of the Corliss engine.” This water was removed from the pits by an ejector, or suction pump.
The plaintiff was in the defendant’s employ from March, 1911, until he was injured in May, 1912. He testified that when he first began to work, the flooring in the engine room had been removed and a new floor laid in February or March, 1912, and that a trap door was then placed in the floor over each pit. He further testified that on the night he was injured he crossed the floor to look at the governor on the engine and fell into the pit on the left of the stairway, the trap door over it having been left open.
There was evidence to show that steam fitters or plumbers had been working in this pit the day before; also that the engine room was light, and that there was an electric light over the pit into which the plaintiff stepped.
The jury returned a verdict for the plaintiff, and the presiding judge asked this question: “Did you find that the trap door was left open by an employee of the company or the plumber’s employees?” The foreman replied: “Plumber’s employees.”
The jury could have found that it was necessary for the plaintiff to pass over the trap door of this pit in order to reach the engine.
O’Malley, a witness called by the plaintiff, who was one of the three watch engineers, testified that when he came on duty at three o’clock that day the trap door was open and he left it open. He further testified on cross-examination that the doors of the pit into which the plaintiff fell “were lifted up to see the height of the water; that it was not required to be open very often; that it might be opened once a week and might be opened two or three times a day, the frequency depending a good deal upon the flow from the exhaust.”
*94There was other evidence to show that this trap door was opened frequently. The plaintiff, however, testified that he never had seen it open before the accident, and that the purposes of this trap door were two: “In case the pipe got clogged up or got worn out to take it out and put in another one.”
In view of this conflicting evidence, “as the jury presumably believed the plaintiff, we must consider the exceptions in the aspect of the testimony which is most favorable to him.” Falardeau v. Hoar, 192 Mass. 263, 266. If for the purposes of this decision we assume in favor of the plaintiff that the question of his due care was for the jury, and that he did not assume the risk of the injury which he received as matter of law, the question whether the defendant was negligent remains.
This is a close question, but we are of opinion that its determination is governed by the case of Young v. Miller, 167 Mass. 224. In that case as in this, it was not disputed that the plaintiff was familiar with the trap doors, knew where they were located, and also knew that they were likely to be opened from time to time. In the case at bar the plaintiff knew that if the pipe in the pit became worn out or clogged up it would be necessary to make such repairs as were needed, and that the only means of access to the pipe was by opening this door. He also knew that the only way of determining the amount of water was by opening the door. While he testified that the pipe probably would not rust out until the end of four or five years, and would not become clogged up for a long time, yet it is plain that from time to time, with more or less frequency, the pipe would become clogged or worn and would need to be cleaned out or replaced.
If it became necessary to clean or repair the pipe more frequently than the plaintiff understood was necessary, this fact would not be evidence of negligence, or distinguish the case from Young v. Miller, supra, for it is apparent that he must have known that the door would be opened whenever occasion required, although he did not know the precise moment when it would be so opened. As was said by this court in Young v. Miller (p. 225): “The plaintiff knew the permanent elements of the danger to which he was exposed. He knew that the trap doors were where they were, and that they were likely to be opened from time to time. . . . The only thing he did *95not know was the precise moment when the doors would be raised, but that he could find out if he looked. ... A majority of the court are of opinion . . . that the defendant’s duty did not extend to giving notice or warning that the doors were open to one who knew that they were liable to be so at any time.”
The fact that in the case of Young v. Miller the plaintiff fell into the pit during the noon hour, at which time he was not called upon to work, did not in our opinion affect the decision of that case, as it is not referred to as a reason for the conclusion reached.
All of the cases relied on by the plaintiff are cases where the plaintiff had no previous knowledge of the existence of the trap door, or did not know it was to be used at the time the plaintiff was injured.
This case is to be distinguished from such cases as Foley v. J. R. Whipple Co. 214 Mass. 499; Falardeau v. Hoar, 192 Mass. 263; Johnson v. Field-Thurber Co. 171 Mass. 481; Hogarth v. Pocasset Manuf. Co. 167 Mass. 225; Dolphin v. Plumley, 167 Mass. 167. See also Horrigan v. Boston Elevated Railway, 190 Mass. 577.
It follows that the ruling requested by the defendant that the plaintiff was not entitled to recover should have been given.
Exceptions sustained; judgment to be entered for the defendant under St. 1909, c. 236.
