The Virginia Chapter of the Construction Owners Association
of America (COAA) will hold its 2014 Fall Workshop at James Madison
University on October 2. The workshop will feature the following presentations:
Attendees will also be able to tour the East Campus Dining Hall, a project completed by Donley's as construction manager.
- New Stormwater Regulations and How They Impact the
Project Design and Construction
- Is Your Way Better Than My Way? (A panel discussion about delivery systems and how BIM impacts each one)
Donley's is a proud sponsor of this event.

Before beginning assembly, disassembly, and/or equipment operations, follow these three steps.
1. Identify the work zone:
- Demarcate boundaries (such as with flags, or a device such as a range limit device or range control warning device) and prohibit the operator from operating the equipment past those boundaries, or
- Define the work zone as the area 360 degrees around the equipment, up to the equipment’s maximum working radius.
2. Determine if any part of the equipment could get closer than 20 feet to a power line. If so, the employer must meet one of the following requirements: Confirm that the power line has been de-energized and visibly grounded at the work site.
- Ensure that no part of the equipment gets closer than 20 feet to the power line by implementing the encroachment procedures.
- Determine the line’s voltage and the minimum clearance distance permitted under Table A (see below) and if any part of the equipment could get closer than the minimum clearance distance to the power line implement the encroachment procedures.
3. Encroachment Procedures (To be used if getting closer than 20 feet or the Table A Clearance Distances)
- Conduct a planning meeting to review the location of the power line(s) and the steps that will be implemented to prevent encroachment/electrocution.
- Utilize nonconductive tag lines.
- Erect and maintain an elevated warning line 20 feet from the power line or at the minimum approach distance under Table A (see below). If the operator is unable to see the elevated warning line, a dedicated spotter must be used.
- Before Operations commence, at least one of the following additional measures must be in place:
- Use a dedicated spotter.
- A proximity alarm set.
- A range control warning device.
- A range control limiting device.
- An insulating link/device.
Things to Remember
- If in contact with power lines, stay on the equipment.
- If you are not currently on the equipment DO NOT touch the equipment or anything else that is contacting the equipment.
- If you must leave the equipment, or area, jump free from the equipment and shuffle your feet in very small steps. After a power line contact, the current flows outward through the ground in a ripple pattern.
- Areas of high and low electrical potential fields circle the energized equipment like ripples in a pond after a stone hits the surface.
Perhaps the best safety tool to come along in industrial construction is the Field Level Risk Assessment (FLRA) or Job Hazard Analysis (JHA). Whatever you call it, this is a tool that makes everyone stop and think about the different risks associated with each task. Customarily, crews gather and write out the JHA or FLRA before performing a task and have found that this exercise greatly reduced the number and severity of injuries.
The same principle of these risk assessments can be done in our shops. Simply take a four-second reset. Take four seconds before starting a new, but familiar, task. The act of re-focusing for a mere four seconds has been shown to reduce the probability of an injury or incident by more than 90%! You may have done the task you are about to perform thousands of times before. In your mind, you know that you could do it with your eyes closed. But keep in mind, it is usually not the task itself but some small thing you did not anticipate that causes the incident.
This four second reset was first instituted on CN Rail as part of a strategy to reduce the number of serious incidents, including numerous injuries that required amputation. CN Rail found that employees knew the rule or procedure to do the job without getting injured but were simply not focused on the task at hand. Even well rested employees were getting caught up in the routine of the day and found themselves daydreaming or thinking about other things.
It is easy to imagine the different activities we do every day and how this applies. For example, getting in a forklift and having a quick look around. We change our thinking from where we are going to focusing on the area, road conditions, other vehicles and so on. This is the reset we are talking about and believe it or not, four seconds is all it takes. Get in this habit of taking four seconds and you will significantly reduce your chance of injury.

Approximately 26 construction workers die each year from electrocutions, falls, and equipment tip-overs all while using aerial lifts. About half of the deaths involve boom-supported lifts, such as bucket trucks and cherry pickers; whereas, scissor lifts account for most other deaths.
Before operating an aerial lift, keep the following in mind:
- BE AN AUTHORIZED OPERATOR!
- Check operating and emergency controls, safety devices (such as, outriggers and guardrails), personal fall protection
- gear, wheels and tires, and other items specified by the manufacturer.
- Look for possible leaks (air, hydraulic fluid, and fuel-system) and loose or missing parts.
- Check the area the lift will travel and be used.
- Look for a level surface that won’t shift.
- Check the slope of the ground or floor; do not work on steep slopes that exceed slope limits listed by the
- Look for hazards, such as, holes, drop-offs, bumps, and debris, and overhead power lines and other obstructions.
- Set outriggers, brakes, and wheel chocks – even if you’re working on a level slope.
- Check the wind speed. Are you above the manufacturer’s maximum wind speed?
