Safety Training

 COVID-19 training course (e-learning) will be available from 12th May

 Mandatory for access from 18th May – checked by safety training for all persons on whitelist

 CERN's LMS (Learning Hub): Learning Hub >> Catalogue >> Safety Training >> Safety & Health

Refresher courses:
 • Most of them are e-learning (e.g. RP Controlled Areas).
 • For those that need physical presence (Self Rescue) the validity will be automatically
 prolonged by Safety Training – by checking the names on the whitelist.
Bat 55 is no more adequate for newcomers to do e-learning – alternative premises are being
prepared.

 8th May 2020 EDMS 2371288

Safety Training

3 face-to-face courses training are mandatory

  Self rescue masks
  via Vidyo
 (demonstration in the tunnel mock-up is suspended for the time being)

  Radiation Protection Training for Controlled Areas
  via Vidyo

  Electrical safety
  via Vidyo
All available from 18th May onwards

Nettoyage renforcé :
• Nettoyage habituel (sols, poussières, etc.) + vider les poubelles
• Désinfection (points de contacts : poignées, interrupteurs, boutons d’ascenseurs,
 rambardes d’escaliers, etc.). Uniquement dans les sanitaires et zones
 publiques/communes.
Les zones concernées sont les suivantes :
• Surface (bâtiments occupés) : sanitaires, restaurant 1, zones « publiques », couloirs,
 locaux gardiens, Service médical, Pompiers, CCC, B55, B904, Salles de contrôle
 AMS/CMS, bureaux et salles de réunions où vous avez reçus un ticket. Dans ces
 zones, on ne touche pas aux équipements informatiques (clavier, souris, etc.) ·
• Bâtiments machines : sanitaires en surface
• Souterrains et machines : pour l’instant pas de nettoyage. Une demande a été faite
 pour les accès (point1,2,3,4,5,6,7), les ascenseurs et les sanitaires en souterrains
 (IMPACT bloqué pour des raisons de mise à jour du Pdp – à confirmer). Des
 campagnes de nettoyage sont prévues à partir de juin.

Implementation to ALICE Environment

 General

• All PPEs for ALICE activities will be ordered and distributed by LEXGLIMOS/TC

• Work procedure: 2 m of physical distance need to be respected @ CERN
  In case the working conditions do not allow to respect the 2 m physical distance, mitigation measures will have
 to be undertaken in consultation with the ALICE LEXGLIMOS/TC

• Masks
  Surgical CERN masks of type 1 must be worn for all ALICE activities
  You are strongly encouraged to wear gloves at all times
  For some activities FFP2 masks and/or face shields or safety glasses could be needed, this will be decided
 following a risk assessment by ALICE LEXGLIMOS/TC
  The mask must be changed at least every 4 hours or in case of damage

 surgical masks of type 1 FFP2 mask face shield safety glasses

• Tools
  Workers should be equipped with personal tools. If not possible, the workers shall use gloves. The tools have to
 be disinfected at least once at the end of the day

 15

Implementation to ALICE Environment

 Access to common areas
• ALICE Workshops
  It is recommended to wear face shields and gloves and to use whenever possible personal tools
 (decision following safety assessment by ALICE LEXGLIMOS/TC)

• ALICE Cleanrooms
  Ventilation to be maintained on high level not to be reduced or switched to standby.
  Respect min. 3 hours of no person in the room (rest-time) between change of occupants
  Face shields and masks shall be worn, if more than 1 person working inside

• ALICE, P2 common areas and kitchen
  The P2 kitchen will stay closed
  The meeting rooms and ARC at P2 will stay closed, except for 3294 R-008 (which will be used as
 check-in point – see later)
  The outside tent (b.6952) and the BBQ point (no more than 4 people) can be used as resting area

• We remind that smoking inside the buildings is strictly forbidden

 16

Implementation to ALICE Environment
 Procedure
 Create an IMPACT for your activity, this will trigger the usual planning and safety assessment, and in
 particular a safety assessment related to the Covid-19 risk
  New IMPACT for any restarting ALICE activity at Meyrin and ALICE P2 (surface and underground)  No generic
 IMPACTS with lots of names
  All Impacts must contain the exact zone/location and all person (and only those), who physically will work there.
  Only workers

Implementation to ALICE Environment

 ALICE Underground
• Max. 3 persons in the lift to UX25 (AS-724) at the same time

• Max. 2 persons in the lift to CRs (AS-715) at the same time

• Everyone will wear a mask

• Respect the distance between each other when waiting for the lift

• All other Personal Protective Equipment required for underground work must
 be worn (e.g. helmet with headlamp, safety shoes, harness, …)

• Need of wearing a face shield will be assessed on case by case via the risk
 assessment by TC/LEXGLIMOS

• In case of evacuation alarm, everybody must evacuate either via PX24 or PM25 as
 usual and the number of people can be more than 3 per lift

• The pressurised area door must not be left open

 18

Check in areas Disposal areas
• Dedicated places where you • Specific containers with
 can find: Covid-19 label will be placed
  Hand sanitizer to dispose masks and gloves

  Type 1 personal mask Draft/ under study

Implementation to ALICE Environment

 Good practices

 At the end of the day, write down with whom you have been in
 contact

 If you notice that there is no soap or paper towels in the toilets or
 empty disinfectant distributers, report to ALICE TC/Safety.

 Wash your hands with soap or hydro-alcoholic solution. Keep in mind
 that as soon as you have touched something even with gloves, your
 hands are “dirty” and you should anyway do not touch your face!

 Even wearing the mask, you must try to always keep the 2 meters
 distance
