Lip kiss for few seconds

From a Far distance the backsides of men are shown.

One man's hand and face are bloody after an accident during a drill, while another man's head is bloody from another accident.

Another crewmember has bad radiation burns on his skin.

During a drill, a man's hand gets caught in a moving chain and pulley, resulting in some blood, while another man accidentally hits his head on some metal structure and is knocked unconscious (with brief blood).

We see a crewmember vomit after being exposed to harmful amounts of nuclear radiation and then see radiation burns on his skin as well as that of another crewmember (that look like standard burns as well as blisters and reddened skin, etc.).

We see a mouse inside a cage in the sub on its side and convulsing from too much radiation exposure. We later see that it's dead.

A man gets his hand caught in a torpedo crane lever. There is blood, which also falls on the camera lens.

What sounded like at least 1 "s" word, as well as 1 slang term for male genitals ("torpedo"), 1 damn and 1 hell used as exclamations.

Alcohol is consumed and some cigars.

Most of the film is quite tense as the second half of it revolves around the submarine's nuclear reactor going out of control, and the men onboard trying to repair it. The scenes in the violence/gore section are pretty disturbing.
