Choose two of the three construction safety issues discussed in this unit (excavations, trenches, and confined spaces), and create a PowerPoint presentation in which you discuss the ways these issues are evaluated by hazard recognition means, methods, and tools, and how one would go about controlling the hazards as they are found. A risk assessment matrix would be one such method. Highlight the known hazards, and address these hazards with mitigation methods. (It would enhance your presentation to provide scenarios or examples from your work or literature from the field.)


Your presentation must contain at least 10 content slides, not counting the title and references slides. You must use at least three sources, and one must be from the CSU Online Library. Photos and graphics are required. You must add either audio or speaker notes to your presentation. The voice should be male.
