No, not a Halloween post — although Slide No. 4 in the Naval Safety Center’s “Signs of the Times” Vol. 6 contains elements of a good ol’, cheezy horror flick: Revenge of the Crocodilians!
The slide show (http://safetycenter.navy.mil/ — midpage, “Signs of the Times #6, a PowerPoint doc) is a collection of similarly bad yet humorous or tongue-in-cheek signage that underlines the importance of labeling hazards clearly and effectively — and taking even official-looking warnings (at least, the civilian versions) with a grain of salt. It’ll take a few seconds to download with a good connection, but it’s worth it.
