fail-safe

They had crossed paths once; Dad had wanted to turn Fail Safe into a movie, a project that Lumet eventually directed.

So as we lurch toward the next “fail-safe” milestone, there must be a way out for both sides.

For example, at Three Mile Island, a fail-safe feature actually made the meltdown worse.

My Social Chef recommends the perfect, fail-safe roast chicken recipe.

Internally, the communications beam to Thule Base had been interrupted; and the fail-safe had not failed-safely.

It designed ingenious models, devised foolproof laws, imposed fail-safe institutions and strongly "recommended" measures.
