Maybe not a professional yet, but I have great experience in preparing presentations and deliver their content to the public. Experience come since university, especially at master level. My jobs required me to make presentations at least 1-2 per week. In the recent program I participated in Germany, they used to call me "5 min ready with a ppt presentation".
Workers safety is also a well known subject, after for 1 year I worked as a CEO of manufacturing company in one of European Union countries. But "lone workers safety" - will be fun.
It depends to whom your presentation adress, to the workers, whom you want to teach some safety rules, to your boss or to the regulation authority to prove you know your job, or it has a different purpose ?
Depending on your preferences, the presentation can be done in PowerPoint format, or, we can make it in movie maker, as a movie.
Power Point offers the advantage to easily stop at any moment and offer aditional explanations or answer questions.
On the other side, a movie-presentation in MovieMaker is better when you want to make sure your presentation is exactly 60 minutes, no loger and no shorter. Picture, text comment on it, your voice with add comment and background music can run in the same time - and that is what makes me to go for movie maker.
However, depending on your target grup,you choose the right solution.
