The D0 Pit Shield Block.  Contact  person is Jim Fagan x 2932.  A ladder is required to get up onto the top of the block.

On top of the block looking down at the lifting hook hole. 

Special hook placed into the lifting hook hole.  The cover plate will slide over this hook.  When the cover is positioned over this hook, pull this hook through the cover plate to secure it.  The purpose of the cover is to prevent someone from attaching a crane hook to this block hook.

The cover plate and hook are in readied to be locked.  The red padlock clamp fits through a hole in the lifting hook to hold it up tightly on the block lifting hook. 

The cover plate is secure with a PAD 118 and D0 Collision Hall cored padlocks.  As a courtesy let Jim Fagan know you are done locking it back up.
