This question already has an answer here:

Some books contain boxes with additional advice, tips or questions which have a signaling symbol on the left (like a question mark, an exclamation mark, a light bulb etc.). Is there a package which offers something like this?

    The \marginpar macro, part of standard LaTeX, can be made quite flexible at placing notifications in the margin. Here's an example of how I have used it: tex.stackexchange.com/questions/101553/… – Steven B. Segletes Apr 6 '16 at 19:52

Here's a version with the powerful tcolorbox and using an underlay, drawing the symbol left of the box -- I chose the bombe symbol from bclogo package, but basically anything can be placed there.

\documentclass{article}


\usepackage{bclogo}
\usepackage[most]{tcolorbox}



\newtcolorbox{attentionbox}[1][]{%
  enhanced jigsaw,
  sharp corners,
  colframe={red},
  underlay={%
    \path[draw=none] (interior.south west) rectangle node[white]{\bcbombe} ([xshift=-10mm]interior.north west);
    },
  #1
}

\usepackage{blindtext}

\begin{document}

\begin{attentionbox}
\blindtext
\end{attentionbox}
\end{document}
