Re: Locked High Rad Areas

Paul,

There is no regulation that requires that you have an individual key to each 
lock.  Some facilities have one key for many locks depending on the area and 
need for access/egress.  You have to determine the best way for you to maintain 
"positive" control over the area. Many facilities have found that using the same
key to access many areas has gotten out of control and they are now switching to
different keys for different locks. By having the same key to all areas, you 
give workers a "carte blanch" to enter any LHRA (which may vary greatly in 
hazard) when you issue a key.

At our facility, we have found that under most cases, controlling "areas" works 
well.(i.e. if we have 5 doors leading to one room, they will all be keyed the 
same).  Different areas have different keys.  This may or may not work for you. 
You should consider your response to lost keys.  If you have too many locks 
keyed the same and you lose the key, you have a lot of access points you have to
guard until you can re-key the locks. If you have separate keys for many areas, 
you may also want to consider having a master key (under extremely tight 
controls) to be used in emergencies.

I hope this is helpful. Feel free to give me a call to discuss LHRAs if you 
would like.  I have been involved with this issue for quite some time.

I'm soliciting information concerning practices related to Locked High 
Rad Areas. When an individual or HP Office is responsible for several or 
many Locked High Rad Areas, is your practice to have one key that fits 
all the locks, or to have a unique key for each lock? Is your practice 
driving by regulation or the result of practical evolution? 
(Unfortunately, these are not the same!)
     
Thanks in advance for your replies.
