place the tip of the gun in contact with the body, thereby "dead-ending" or blocking it Explanation: Taña has already quoted a definition of "dead-end" in this context: blocking the tip of the gun. But it might help to have an explanation of the exact nature of this "dead-ending" and the reason for not doing it. To dead-end a pneumatic gun is to block the tip. To dead-end it against the user or someone else is to place the tip in contact with the person's body, which of course has the effect of blocking it. This doesn't refer to the danger of firing a nail into the person by mistake from a pneumatic nail gun. It doesn't refer to nail guns, but to any pneumatic gun. It's because of the danger of air penetrating the body: "Compressed air is extremely forceful, with pressures used in the workplace typically ranging from 80 to 120 pounds per square inch (psi). The primary concern associated with using air at this pressure is the potential to “dead-end” or block the tip of an air gun. If the gun is “dead-ended” against the skin, compressed air can enter the body through small cuts or punctures. Results can range from soft tissue damage to an embolism (air bubble in the bloodstream). Compressed air can also rupture internal organs if introduced into a body cavity, such as a nostril or ear." https://ehs.psu.edu/sites/ehs/files/compressed_airgun_inform... -------------------------------------------------- Note added at 1 day2 hrs (2017-10-23 05:48:56 GMT) -------------------------------------------------- Hi Monica No problem about closing the question, but I'm sorry you didn't receive a notification; clearly the system failed there. I just hope the information reached you in time to be useful. -------------------------------------------------- Note added at 5 days (2017-10-27 08:30:30 GMT) Post-grading -------------------------------------------------- Thanks, Monica. I think that people like you who have helped so many others are entitled to ask a question or two when working against the clock! I know just what you mean; given time you can find the answer yourself, but sometimes time is what you don't have. |
