Safety at CERN in the context of worldwide collaborations

R. Trant - A. Henriques EDMS # 1431406 2

Session 5 of International Conference on Standardization and Innovation13-14 November 2014 @ CERN, Geneva

R. Trant - Head of the HSE Unit

(Prepared by A. Henriques & R. Trant)

Safety @ CERNCERN’s Safety policy reflects the specific legal, technical & operational features, such as:

• Cutting-edge and unusual (“non state-of-the-art”) technologies• Major “industrial” site, ~45 km of radiation areas, … • Dynamic installations according to research needs• ‘Open’ organization with many users/trainees as well as

equipment from institutes all over the world• Extensive presence of contractors on site • Intergovernmental Organization establishing its own legal

framework as necessary for its proper functioning • Site straddling the CH-F border• Collaboration with host states - “tripartite approach”


CERN Safety Rules

• CERN establishes and updates Safety Rules applicable to the Organization’s activities on the whole of its site.To this end, it takes into account the laws and regulations of the Host States, EU regulations and directives as well as international regulations, standards and directives.

• The Safety Rules established by the Organization are deemed to fully cover the matter concerned.Where the Organization does not establish Safety Rules, the relevant laws and the regulations of the Host States apply on a territorial basis.

• The Organization takes the necessary measures to ensure compliance with its Safety rules.


International Collaboration @ CERN


CERN is an international organization, with collaborating institutes fromaround the globe & a good example of International Collaboration

Safety rules & Standards


CERN Safety Rules

European Safety Regulation

In line with

Based on

Directives Obligatory (“binding”)

Standards not obligatory (unless they are specified in CERN Rules) but important and highly recommended

CERN Safety Rules SR-M & GSI-M2

European Safety Regulation

In line with

Based on

Directives 2014/68/EU - PED

Standards ISO 9712 (harmonized)

Example – Welding on Pressure Vessel

Standardization – Approach


Why are standards important and “highly recommend” ?

1. If classified as “harmonized standards” with a certain Directive, they‘provide presumption of conformity to the Essential Safety requirements of theDirective’

2. They provide a unique approach to designers and manufactures in anorganization/collaboration

3. They are used as engineering guidelines to implement Safety in projects

List of harmonized standards:http://ec.europa.eu/enterprise/policies/european-standards/harmonised-standards/index_en.htm

Standardization – Examples


Some Examples of harmonized International Standards

• Electrical domain

IEC 61000 series Internationalization

• Laser domain

IEC 60825 series Internationalization

• Welding domain

- EN 288-2

- EN 288-5

Standardization – Challenges


What if the standards used are notharmonized with the EU Directives ?

Main challenges:• Exhaustive analysis• Resource consuming

Standardization – Challenges


… not only at CERN … - example: ITER Organization for the “tokamak”

Procurementsharing:

PED is required but ASME Codes are used:

a very exhaustive Conformity Assessment document was drafted

G. Sannazzaro, “Selection of C&S for the ITER Systems and related issues” – ITER, France, September 2014

Standardization - Challenges @ CERN


Example: Sizing of Safety Valves for Cryogenic Vessels Standards:- ISO 4126

- EN 13648

- None

Chemical & Petroleum Industry

Standard cryogenic systems, but not only in Europe

‘Non-standard’ & very low temperature systems (LHe, Superfluid He)

Solution at CERN:

Implement own ‘standard’ (guidelines, best practices, tools for non-standard equipment; e.g.: Kryolize® software


Innovation – CERN is ‘pushing the boundaries’ of science and technology

• Prototypes & ‘non-standard’ equipment

• ‘Non-standard’ facilities with an unusual combination of risks(RP, ODH, Fire, etc.)

Solution at CERN:

• Adapt and get “inspired” by standards which, themselves, aren’t 100%applicable to some CERN’s facilities.

E.g.: ventilation in accelerator facilities

‘Inspired’ by:- ISO 17873: Ventilation systems

for nuclear installations

‘Adapted’ by:- Ventilation Working Group &

cope with the authentic risks

Standardization - Challenges @ CERN

International standards to facilitate our work

Standardization – Solutions


1 International/Global Standard

ISO standard

ASME

EU Directive

orInternational organizations to harmonize as much standards as possible with

the different “regulators” (e.g. Europe, USA, Japan, etc.)

CERN, as an experienced R&D laboratory, shares its knowledge industry (via Knowledge Transfer Group)

CERN to share its experience & knowledge with

the International Standard’s Technical & Scientific committees?
