Hydrogen Hazard

Potential Explosion Hazard Exists for this Buoy

Explosive hydrogen gas can accumulate inside the hull of 3-meter-discus buoys.

This dangerous gas is caused by batteries corroding due to water intrusion. While a remedial plan is being developed, mariners are asked to give this, and all other 3-meter-discus buoys, a wide berth. The buoys are 3-meter discus shaped, typically with a yellow hull and a 5-meter tripod mast. Each buoy is identified by the letters "NOAA" and the station identifier number, such as "46050". Each buoy has a group of (4) flashing 20-second, yellow lights.

Please do not trespass, tamper with, or tie up to any NOAA data buoy.
