The Philippine Space Agency (PhilSA) on Wednesday cautioned the public against debris that may fall from China’s rocket in drop zones within the Philippine Exclusive Economic Zone (EEZ).

In a rocket launch advisory, PhilSA confirmed that the People’s Republic of China had launched the Long March 7A rocket, its discarded parts projected to fall approximately 45 nautical miles away from Burgos, Ilocos Norte, and 67 nautical miles away from Camiguin Norte.

The rocket was launched from the Wenchang Space Launch Site in Wenchang, Hainan, at around 06:40 a.m. on December 31. A Notice to Airmen (NOTAM) warning of an “aerospace flight activity” included details on the debris drop zones.

“While not projected to fall on land features or inhabited areas, falling debris poses danger and potential risk to ships, aircraft, fishing boats, and other vessels that will pass through the drop zone. There is also a possibility for the debris to float around the area and wash toward nearby coasts,” PhilSA said, adding that they are not ruling out the possibility that more parts of the rocket may re-enter Earth’s atmosphere.

The agency advised the public to notify authorities should they sight suspected debris, and warned them that this debris may contain remnants of toxic substances like rocket fuel, and so to refrain from retrieving or coming in close contact with these materials.
