A containment hood may include a first shell portion, a second shell portion and a lid portion. The first shell portion may include a first interior-facing surface. The second shell portion may be spaced apart from the first shell portion and may include a second interior-facing surface. The first and second interior-facing surfaces may oppose each other. The lid portion may extend between and engage the first and second shell portions. The lid portion may cooperate with the first and second shell portions to form at least a partial enclosure defining an interior volume. The first and second shell portions and the lid portion may cooperate to define a first opening through which a user is able to access the interior volume.
