In this case, the parties agree that Electric Boat is immune from liability
for simple negligence. See §§ 440.10–.11, Fla. Stat. (2014). Nevertheless,
a subcontractor is not immune from liability where the “major contributing
cause” of the accident was the subcontractor’s own gross negligence. See
§ 440.10(1)(e)(2), Fla. Stat. (2014).
This court has explained the difference between simple and gross
negligence as follows:
[S]imple negligence is that course of conduct which
a reasonable and prudent man would know might
possibly result in injury to persons or property
whereas gross negligence is that course of conduct
which a reasonable and prudent man would know
would probably and most likely result in injury to
persons or property. To put it another way, if the
course of conduct is such that the likelihood of injury
to other persons or property is known by the actor to
be imminent or “clear and present” that negligence is
gross, whereas other negligence would be simple
negligence. Carraway v. Revell, 116 So. 2d 16 (Fla.
1959); Bridges v. Speer, 79 So. 2d 679, 682 (Fla.
1955). [G]ross negligence consists of a conscious
and voluntary act or omission which is likely to result
in grave injury when in the face of a clear and present
danger of which the alleged tortfeasor is aware. . . .
Accordingly, to establish a case submissible to a trier
of fact there must be a prima facie showing of a
composite of circumstances, which, together,
constitute a clear and present danger; there must be
a prima facie showing of an awareness of such
danger; and there must be a prima facie showing of
a conscious, voluntary act or omission in the face
thereof which is likely to result in injury. Glaab v.
Caudill, 236 So. 2d 180 (Fla. 2d DCA 1970).
