Construction Safety Unit IV Assignment – Struck-By Hazards Student Name: David Norrell Date: 03/14/18 Instructions: Each of the following slides contains a construction site photo that depicts one or more struck-by hazards. There is also a construction math slide following the photo slides. Examine each photo, and answer the questions in the notes section of each slide. Make sure to also move the red arrow (provided in the bottom left corner of each slide) to point toward the location of the hazard. Also provide an answer in the notes section of the construction math slide. Show your work for the calculation you are asked to perform. Save the completed presentation, and upload it into Blackboard. Be sure to put your name at the top of this first slide!

Figure 1 (Occupational Safety & Health Administration [OSHA], 2003.) Identify and describe the struck-by hazard in this photo. Move and place the red arrow over the photo to indicate the locations of the hazard. What OSHA construction standard(s) could be cited? What would you recommend to correct the hazard? Figure 1 (Occupational Safety & Health Administration [OSHA], 2003.)

Figure 2 (OSHA, n.d.-a.) Identify and describe the struck-by hazard in this photo. Move and place the red arrow over the photo to indicate the locations of the hazard. What OSHA construction standard(s) could be cited? What would you recommend to correct the hazard?

Figure 3 (OSHA, n.d.-b) Identify and describe the struck-by hazard in this photo. Move and place the red arrow over the photo to indicate the locations of the hazard. What OSHA construction standard(s) could be cited? What would you recommend to correct the hazard?

Figure 4 (OSHA, n.d.-c) Identify and describe the struck-by hazard in this photo. Move and place the red arrow over the photo to indicate the locations of the hazard. What OSHA construction standard(s) could be cited? What would you recommend to correct the hazard(s)?

Figure 5 (OSHA, n.d.-d) Identify and describe the struck-by hazard in this photo. Move and place the red arrow over the photo to indicate the locations of the hazard. What OSHA construction standard(s) could be cited? What would you recommend to correct the hazard(s)?

Construction Math Application Project Please calculate the force on the sling “c” depicted in the image to the right. Also use rules of thumb to determine “c” when Angle A is 45 degrees and 60 degrees. Why do you think the load decreases as Angle A increases? Hint: Information for completing this slide can be found at the end of your unit lesson. Also, do not be intimidated by this slide. Once you review the materials in the unit lesson, you should find this exercise quite simple to complete and interesting as well.
