A safety device for a ladder and one or more support platforms disposed upon an underlying roof surface comprising a panel member having a top side, a bottom side, a back edge portion, a first side edge portion, a second side edge portion, and a front U-shaped edge portion with laterally spaced-apart forwardly extending arms for positioning a ladder there between to contain the ladder and prevent its lateral movement beyond the arms. The panel member and the support platform each has the means in cooperating relation to attach the panel member to the support platform in releasable engagement to enable the panel member and the support platform to easily disconnect and reconnect to further enable the adjustment of the positioning of the panel member relative to one or more adjacently or closely placed support platforms situated along or near the edge of said roof surface. |

1. A safety device for a ladder comprising:
a panel member, said panel member having a top side, a bottom side, a back edge portion, a first side edge portion, a second side edge portion, and a front U-shaped edge portion with laterally spaced-apart outwardly extending arms for positioning there between said ladder for containing said ladder and preventing said ladder's lateral movement beyond said arms; one or more said support platforms disposed upon an underlying roof surface having a roof edge, each of said support platforms having a top section with a first end section, a second end section, a first side edge and a second side edge and a bottom section adapted in frictional engagement with said underlying roof surface, said top section having a surface formed with a plurality of horizontally disposed ribs to provide and ensure stable footing; said panel member and said support platform each having means adapted for releasable engagement to enable said panel member to easily connect to and disconnect from said support platform to adjust the positioning of said panel member relative to one or more of said support platforms situated along or near the edge of said roof surface. |
