Practices for Roof Work

The following practices are required by ALL people working on Kenyon/Belize solar power projects.

  1. No structurally unsafe roof or roof at or above 25 degrees incline with be used. No roof will be greater then one story unless special safety precautions have been made (such as scaffolding).
  2. A Kenyon leader will always be the first on the roof, and will take note any dangerous aspects, such as skylights, weak areas, power lines etc. The leader will also determine the location of the panels and wiring. All people going on the roof to work will be briefed by this leader prior to going on the roof about the dangers.
  3. The panels will be positioned so that workers do not have to get within 10' of the edge of the roof while working.
  4. Getting on roof. If a ladder is used it must be secure, at a 4:1 angle, have both feet feet secure, and have the top 3' above the roofline.
  5. There must ALWAYS be a person at the bottom of the ladder holding the ladder. They will remain as long as anyone is on the roof.
  6. When possible there should be a person at the top of the ladder, who will hold the ladder, and assist the person coming on the roof, or going back down.
  7. There must always be a runner near the bottom of the ladder as long as anyone is on the roof. The runner will be aware of what is going on on the roof, and will listen for needs from those on the roof. (Such as sending up or bringing down tools). This person will have no other duties other then to act as a runner for those on the roof.
  8. A third person on the ground will stand back and monitor the people on the roof to watch for problems, and be prepared to call for and provide assistance as needed. They should be able to communicate to the runner as well. They should not leave their post while people are on the roof.
  9. Tools and supplies will be pulled up to the roof on a rope securely tied to the tool. The rope puller will be next to the ladder in order to have something to hold onto while they pull up the tools. A second person will hold the ladder top.
  10. If for some reason someone needs to be within 10' of the roof edge other then at the ladder site, there must be a rope grab. A roof grab is a roof that goes over the other side of the roof, and is securely attached to something on the ground, or continuously held by a person. The person will hold this rope while near the edge.
  11. No person shall be on a roof for more than 45 minutes in order to avoid fatigue. People will rotate as needed.
  12. Tools on the roof must be placed in a secure location while not being held to avoid them sliding off the roof and hitting someone. Often this will be at the top of a panel.
  13. Normally the max number of people on a roof will be limited to four people. When possible should always be at least two.
  14. Getting up panels up on the roof. There should be three or four people on the roof, and four people on the ground while a panel is being send to a roof. The panel will be slid up the ladder by two or three people on the ground while one holds the ladder. Two people, who are on the roof will be holding the ladder with one hand, and will grab the ladder with the other hand. A third person will stand in the middle and hold the ladder with both hands to make sure it is secure for the other two people.
  15. The total (minimum) number of people dedicated to roof work will be 7-9 people. Unless these people are available, roof work will not be possible,
    • One holding ladder
    • One near ladder to act as runner
    • One standing back monitoring roof activity
    • One holding rope on other side
    • Three to four on roof
