Antoine Nelson appeals his sentence following his guilty-plea for assaulting an employee of the United States in violation of 18 U.S.C. § 111(a)(1) & (b). Nelson’s sole argument on appeal is that the district court erred in applying U.S.S.G. § 2A2.2 based on its finding that the boiling water thrown by Nelson onto a corrections officer was a “dangerous weapon” under the Guidelines. Nelson argues that under § 2A2.2 a “dangerous weapon” refers only *590 to “instruments” and not to substances, such as water. Nelson does not refute, however, the district court’s finding that the assault caused serious bodily injuries.

Nelson has failed to demonstrate any error in the district court’s finding that the hot water, in the manner used and in light of the injuries sustained, was a “dangerous weapon” under § 2A2.2. Accordingly, the judgment of the district court is AFFIRMED.
