Even before we get into the rules and details about construction safety, we can look over some photos that have obvious rule violations. Write a discussion post addressing all four of these photos, and then comment on two of your classmates’ posts.<\/p>\n
Photo 1: A job-built ladder<\/p>\n
<\/p>\n

This wooden object was made of scrap wood, and was used over two days as a ladder on a residential construction site. It has a single nail holding the diagonal brace and there is no horizontal brace. It has no rungs, and no way to stand on the ladder. Yet, unbelievably, the device was used without incident, not owing to the design, but sheer luck.<\/p>\n
What else is wrong with using a device like this on a construction site?<\/p>\n
Photo 2: Residential roofing job<\/p>\n
<\/p>\n

This construction worker has been asked to apply roofing material, probably shingles, over this sub-roof of oriented strand board (OSB). Yet the employer was either too cheap to but scaffold to work from, or rent a manlift, or even supply a harness and anchorage so the worker does not get injured if he falls. Why do tyouthink the square hole was cut into the OSB? Hint: probably because the workers in above the length of a typical extension ladder and this is the employer\u2019s idea of \u201croof access\u201d. <\/p>\n
What else do you see that could cause a worker to fall?<\/p>\n
Photo 3: Scaffolding safety<\/p>\n
<\/p>\n
Photo credit: G. Winn<\/p>\n
What you see in this photo is one of the very most frequent violations of construction safety rules: allowing employees to work on the top scaffold level without full guardrails, which would consist of a top rail, a mid rail and a toe board. On the more positive side, the scaffold is fully planked from left to right, and both levels are strengthened by diagonal braces on left and right sides.<\/p>\n
Is there anything else you can see wrong with this photo?<\/p>\n
Photo 4: Who could actually walk on this?<\/p>\n
<\/p>\n
Photo credit: G. Winn<\/p>\n
In this photo, the employer has asked the employee to erect a ladder jack, quite common, in which the left and right vertical sides are elevated about a foot at time by the worker raising the walk board by operating a foot lever. But instead of a \u201cstage\u201d or \u201cpick\u201d to work from, the employee has given the worker a ladder to walk on: tricky and hazardous if not impossible. In addition, the ladder is not equipped with fall protection to keep the worker from tipping over backward even if he or she could walk and work from it.<\/p>\n
Is there anything else wrong here?<\/p>\n
A ladder jack is supposed to look like this: note the guardrail, midrail and toeboardinstalled properly. The rails still move up and down with the platform.<\/p>\n

These hazards are all construction-related and easy to spot. Preventing them in the first place is a lot harder than just spotting them. Preventing them requires rules, enforcement, prgrams and training.<\/p><\/p>\n \n
