Everyone has a role to play in promoting safe working conditions and minimising the risk of accident and the possible consequences. Good communication and cooperation between designers, operators and users is also an important safety factor.
Accidents are rarely attributable to a single cause. In the majority of cases, several risk factors combine to cause an accident. According to the statistics of national safety bodies, the main risk factors in a working environment are:
The human factor must always be taken into account for two reasons:
- man is the main cause of risk,
- and in the end the main victim.
Group leaders must take the necessary steps to ensure that all members of the personnel in their group are given the required safety information. Safety training courses are intended for all persons working on the CERN site, including students, apprentices, contractors’ personnel and registered visitors.
The purpose of the various training courses is to make people aware of risk prevention and risk management issues and therefore to draw their attention to the Organization’s safety regulations and provide them with information on accident prevention, first aid and fire-fighting.
In particular, safety briefings for newcomers are held every Tuesday; they are compulsory for all persons working on the CERN site. On request, these courses may be given in languages other than French and English.
Experts from Safety Commission are available to help with general training or any other safety-related issues.
Special safety courses are regularly organised in the following fields: first aid, use of hoisting equipment, electrical safety, industrial safety, use of flammable gases and chemicals, work in confined spaces, etc.
Work to be done by contractors on the CERN site must be announced by means
of a "Notice
of Start of Work" (AOC: Avis d’ouverture de chantier) issued by the
work supervisor (member of the CERN personnel supervising the work or outside
supervisor mandated by the Organization).
The AOC forms an important part of the risk prevention plan.
The AOC is sent to all CERN services and all persons concerned, both to obtain their comments and to inform them of and draw their attention to the risks and any constraints associated with the worksite (see Safety Instruction IS 39).
If in doubt about the need for an AOC, supervisors must consult EN-GMS-SIS.
Either directly (see List
of Safety Inspectors) or by bringing in outside experts, EN department
carries out various inspections of infrastructure, including, where appropriate,
checks on working methods, work stations and the working environment. The
of safety inspections is to assess the risks from the point of view of all
the safety aspects mentioned above.
Safety Instruction IS 4 defines two types of safety inspection, namely:
Following each inspection, the Safety Inspector draws up a report, which is forwarded to the following persons:
|Subject||Report sent to|
All measures cited in an inspection report are compulsory unless they are indicated as recommendations. The person to whom the report is sent must notify the author when the work referred to has been duly completed or give the reasons why it has not been done.
In some areas, a "level 3" alarm will automatically activate the fire-extinguishing systems (see Annex I).
Laboratories, workshops, halls and special equipment may be fitted with local emergency stops, whose activation is not generally transmitted to the Fire Brigade (see Safety Instructions No. 5 and No. 37).Evacuation alarms
Boxes for triggering the evacuation alarm are installed near some emergency stops, together with red telephones.
Anyone encountering a toxic gas leak or fire which cannot be extinguished with the equipment available locally (e.g. fire extinguishers) and which may place lives in danger must activate the evacuation alarm.
If an alarm goes off, stop work immediately and leave the area.
Level 3 alarms are those which are triggered in the event of an accident or abnormal situation which places or is likely to place lives in danger. Their activation therefore results in the immediate intervention of the Fire Brigade. The following alarms fall into the "level 3" category:
Notes on level 3 alarms
To ensure the efficiency of the rescue operation and whenever the circumstances allow, it is recommended that the triggering of a level 3 alarm be confirmed by a call to the Fire Brigade on 74444, giving all the necessary information (exact location of the incident, number of injured persons if applicable, seriousness of the incident, etc.).
In the framework of training the personnel in fire fighting and to check the alarm installations, evacuation exercises must be performed regularly (see Code E) on the initiative of the department head and in collaboration with DGS-SEE in all buildings fitted with an evacuation alarm system.
The purchase of certain products or equipment is subject to authorisation by the occupational Health & Safety and Environmental protection (HSE) Unit. For each of the products listed below, an internal purchase request (DAI) must be approved by a technical expert from HSE Unit, who will also take the necessary steps to check that the specification complies with the regulations. For FP’s Purchasing Service, it is important that the activity code is clearly shown on the DAI.
