The risk assessment is carried out by the activity manager in collaboration with the DSO/LEXGLIMOS/EXSO of the department or experiment. Please refer to Safety Guideline SG-OHS-0-0-1, “Risk assessment”:

Safety Guideline SG-SH-0-0-2, “Safety signs”, specifies the different types of safety signs that can be used at CERN. To order a safety sign, visit the online CERN Stores catalogue. To request new pictograms, please contact the HSE department.

For safety advice when preparing and setting up your event, contact the DSO/LEXGLIMOS/EXSO of your department or experiment and the HSE unit at the following email address: safety-support-events@cern.ch.

The first step is to contact the DSO/LEXGLIMOS/EXSO of your department or experiment and then the HSE department. It is recommended that you refer to Safety Guideline SG-OHS-1-0-1, “15 key questions to ensure the safe running of your event”, EDMS 1274277.

• Complete Safety Form SF-SH-0-0-8, EDMS 1698140.
• Arrange a meeting or a visit to the event site with the DSO/LEXGLIMOS/EXSO and the HSE department to discuss your safety documents, the timetable and any unresolved issues.

You can then complete and update your safety documents.

That depends on the nature of the event and the facilities concerned. Shortly before the day of the event, the HSE department will organise inspections to check, in particular, the tents, the stage, the power supply and other criteria, as required.

Yes, there is a charge for inspections. The person in charge of the event must take into account the cost of the inspections that will be carried out.

Even if certain details of the event are missing, Safety Form SF-SH-0-0-8 should be completed as far as possible and this initial version sent to the HSE unit: safety-support-events@cern.ch. This will enable the HSE unit to discuss the event with the safety specialists and the CERN Fire and Rescue Service. If other safety-related documents are available, they should also be sent to the HSE unit.

The requirements and provisions relating to the risks of lone working are set out in General Safety Instruction GSI-SH-2, “Lone working”, and Safety Guideline SG-SH-2-0-1, “Guide for the implementation of GSI-SH-2 – Lone working” (French only). For an examination of a specific case, contact the DSO/LEXGLIMOS/EXSO of your department or experiment.

Working alone counts as lone working and should be managed accordingly. You should follow the requirements and provisions of General Safety Instruction GSI-SH-2, “Lone working”, and Safety Guideline SG-SH-2-0-1, “Guide for the implementation of GSI-SH-2 – Lone working”. In a confirmed case of lone working, the risk should be mentioned on form OHS-0-0-3. For any support you may need, contact the DSO/LEXGLIMOS/EXSO of your department or large/medium/small experiment.

If the PPE is in its original packaging and was manufactured no more than 10 years ago (or is within the manufacturer’s expiry date), it can be used without needing to be checked by a competent person. This does not exempt all PPE users from checking that their equipment is in good condition each time it is used, including the first time.

PPE for working at a height must be checked by people with the necessary competence. For members of the CERN personnel, PPE for working at a height is checked by the CERN Stores.

PPE for working at a height must be checked annually by people with the necessary competence. In addition, all users of PPE for working at a height must check that it is in good condition each time they use it.

PPE for working at a height and for respiratory protection requires an annual check. In addition, all users of PPE for working at a height and for respiratory protection must check that it is in good condition each time they use it.

For any questions related to this subject, contact the DSO/LEXGLIMOS/EXSO of your department or experiment.

The self-rescue masks authorised at CERN are listed in the document “Working on the CERN Site” EDMS 1155899. They have been thoroughly evaluated and confirmed to deliver the necessary performance to enable safe evacuation of CERN’s facilities should the need arise.

At CERN, it is compulsory to wear a helmet in places where the signs indicate this requirement, such as underground installations, technical halls, etc. Helmets must be worn directly on the head, with the exception of special equipment such as hoods or other protection against the cold that have been specially designed for use with helmets.

Clothing that does not cover the whole leg is not permitted in technical or high-risk areas, e.g. workshops, laboratories, experimental and test areas, the accelerator complex, areas subject to radiation protection regulations, construction sites, electrical substations, etc.

There are no specific rules imposing a particular type of hearing protection. The type of hearing protection to be worn must be determined by a risk assessment based on the noise level and the associated frequencies, exposure time, the activity and the working environment.

In each case, the PPE required is determined after a risk assessment has been performed for the activity concerned. The risk assessment is carried out by the activity manager in collaboration with the DSO/LEXGLIMOS/EXSO of the department or experiment. In line with the general principles of prevention, safety must be ensured by means of collective protective equipment (CPE) and, failing that, by means of PPE alone. Please refer to Safety Guideline SG-OHS-0-0-1, “Risk assessment”.

The rules on accessibility for people with reduced mobility must be implemented in the following situations:

• Someone with reduced mobility will be using the building;
• Renovation work will be carried out;
• A new area will be built.

Information on the rules applicable to accessibility for people with reduced mobility can be found in the document “Réglementations française et suisse concernant l’accessibilité des personnes à mobilité réduite” (French and Swiss regulations on accessibility for people with reduced mobility).
