1960's Lockheed/Japan/Nagoya era photo, what might this kanji be?

[skatefriday]

Post WW2 Lockheed was building F-104’s in Nagoya. I came across a family photo from that era and would like help identifying what this sign says.

Ha! 注意 I know, but wouldn’t have recognized the way it’s written there.

This certainly makes sense for the factory and what was being built there. Thanks!
