「in case of」の使い方

When I was on the airplane, there was a message to the effect that:

• In case of an emergency landing in water, use the seat cushion as a flotation device.
• to the effect that ～という旨の The government made a statement to the effect that it's against the war. : 政府は、その戦争には反対であるという趣旨の声明を発表しました。(definition from Eijiro on the Web)
• 降下 (こうか) (n,vs) fall; descent; (plane) landing; (atmos.) depression; (P); (definition from Edict)
• flotation device 救命胴衣｛きゅうめい どうい｝、救命具｛きゅうめいぐ｝(definition from Eijiro on the Web)

It means "if there is an emergency landing in water, you should use the seat to avoid drowning."

• 水死 (すいし) (n,vs) drowning; (P);

In the case of "in case of", use it like this:

• In case of __(n)__, (imperative sentence).

Here's some really strange marketing copy. It says:

• Breath Communication / Etiquette

Let me give you some advice, OK? In case of someone trying to communicate with you by means of their breath, run like hell.

• like hell 死に物狂いで、必死に (definition from Eijiro on the Web)
