[SML] OSHA Industrial Fall Protection

[Dale Farmer]

Ah.  These are more like antenna masts.  I was envisioning something 
relatively light like a CB radio antenna.    Okay.

How about a railing system.  Stanchion at each corner that locks into 
the stacking brackets of the container.  Kevlar cables strung to create 
the rails and not interfere with the RF patterns, similar to what they 
put on navy ships.   Probably will need a stanchion every ten feet or so 
along the long edge, so some additional welding work needed to make post 
holes, as it were.   If the thing doesn't need to remain ISO container 
external stacking standards and highway clearances, just leave the 
railings permanent.
   Might be able to adapt the railing systems used for construction 
scaffolding, if RF interference isn't an issue. Make the spare parts 
issues for the inevitable replacements needed a lot simpler.   Those 
railings should stand up to most winds, so they wouldn't have to come 
down for storms.

Weld a anchor point to the center of the roof.  Hook a yoyo to that, the 
other end to the fall arrest harness.   Won't keep the person from 
falling off the edge, but should keep them from hitting the ground.

Hope these ideas help.
