G.Bobbink (Management Board L3)
Very Important
Start of Dismantling L3 after purge of gas and electrical safety is assured
in other words:
Don’t dare to put out ANY module or crate!
L3 stays as it is at least until 8.12.2000

Work in heigth:
Keep at least 3m away from operational machine
Safety shoes everywhere on point 2
Helmet in UX25, U2, U5 (cavern), P5
Gloves recommended
Only specially trained persons
Use of approved equipment

2 counters: 1 general LEP and 1 local (INB)
all readers are connected to central control room
new access database (updated after safety course)
for L3: access via small lift PX24, 2 two-way readers
for LEP : access via large lift PM 25
bringing up of material via lock

( gas detection will be dismantled by ST/EL
after purging of gas systems (FGSO))
Alarm level 3 test by TIS/GS
and the GLIMOS before dismantling
No smoking in dismantling areas
Every flammable material, e.g. wood, has to be brought onto
the surface every evening and put into the metal trash bins
Welders or other technicians must use adequate protection equipment against sparks or high temperatures pieces
Fire

Check 400 km of cables by ST/EL under control and responsibility by ST/EL and the GLIMOS
Every rack and power output is checked individually
for the Normal-, Experiment-, Safety- and UPS circuits
in P1, P2, P3, P4, P5, MCR, U1, U2, U4, U5, UX25 and SG2
Time estimate: 5 days, NO dismantling before!
Temporary power lines and sockets are available
Disconnecting of electrical cables from 1. to 7.12.2000

No rack cooling
No air conditioning
Stop of rough water supply (including mixed water) on 4.12.00

Restricted access to cavern
Normal run conditions
Safety shoes and helmet not needed

will immediately be denied to have access to point 2
Every action putting other peoples live in danger will be regarded as professional fault
