Here is an article that talks about ZAP and whether or not they make for an effective safety symbol.

In the 1980’s, a communication supervisor at Ontario Hydro (Hydro One) created a campaign featuring a cartoon bird named, “ZAP the Safety Bird”. Designed as a safety initiative aimed at keeping children aware and safe from electrical hazards, ZAP is also typically found on hazard labels in Canada.

In the safety campaign, ZAP was a pelican with a red ball cap worn backwards, flying overhead spotting electrical hazards and flying down to warn children before they were injured.
