SAFETY COLOURSAND SAFETY SIGNS
1 LEGAL BASIS
This code is based on the document SAPOCO/42, 1988 edition, which defines thesafety policy at CERN. It is issued in application of the CERN Staff Rules andRegulations.
2 SCOPE
This code defines for CERN the standard safety colours and safety signs to giveinformation on existing risks or dangers and to indicate an interdiction, a warning, amandatory action, an emergency escape, or the location and identification of first-aidand fire-fighting equipment.
This code also takes into account the EEC Directive 91/C53/06 which requires thatthe laws, regulations and administrative provisions in the EEC Member States mustcomply with this Directive as from 1 January 1994 onwards.

3 GENERAL REQUIREMENTS CONCERNING SAFETY SIGNS
The information and instructions in the following table apply to all safety signs:
COLOUR MEANING or PURPOSE INSTRUCTIONS
Prohibition Avoid dangerous actions
RED Danger - AlarmStop, shut down,turn off power,evacuate
Fire-fighting equipment Identificationand location
YELLOW Warning Be careful, take precautions,examine
BLUE ObligationPrescription of specificbehaviour or action.Obligation to wear personalprotective gear.
GREEN
Emergency escape routesFirst-aid
Doors, exits, routes.Equipment, identification,location.
No danger Back to normal
A safety sign (signboard) refers to a specific object, activity or situation and providesinformation (warning) about a hazard or danger to health and safety at work, aprohibition, a mandatory action, an escape route or the location of fire-fighting andfirst-aid equipment.
Signboards must be installed by the Division (Group) responsible for the work orthe operation of equipment creates hazards or danger. These signboards must beplaced at a suitable height, taking into account any obstacles, either at the accesspoints to an area (general risk), or in the immediate vicinity of a specific risk orobject. Phosphorescent colours, reflecting materials or artificial lighting should beused whenever the level of natural light is inadequate.
Edms 335505

The placing of too many signs too close together must be avoided. Signboards mustbe cleaned, maintained or replaced (if necessary) at appropriate intervals. Asignboard must be removed when the situation to which it refers no longer exists.
General European safety signboards relevant for CERN are shown in Annex I andthe main CERN safety signboards in Annex II. CERN safety signboards relate tospecial activities or dangers at CERN or provide specific and detailed information.Where general safety signboards are considered not to be sufficiently complete orexplicit, CERN safety signboards should be used (example: radiation, dangers due toelectricity, etc.).
4 MARKING OF CONTAINERS AND PIPES
Containers which hold dangerous substances must be labelled as defined in theChemical Safety Code B. Self-adhesive or painted signs must be placed on the visibleside(s) of the container.
Visible pipes must be colour-coded indicating the main categories of contents:
waterairsteamflammable oils / liquidsoxygen (gas / liquid)gases other than air and oxygenacidsbases
greenlight bluesilver greybrownwhiteamberpurpleblack
Preferably, the entire visible length of the pipe should be painted in the appropriatecolour but, at least near the most dangerous points (valves, joints, etc.), rings mustbe painted at reasonable intervals and appropriate labels (name stickers) must beinstalled.
5 OBSTACLES AND DANGEROUS LOCATIONS
Places which are accessible to persons and present a risk of colliding with obstacles,of falling or dropping of objects, should be marked with alternating yellow andblack stripes of about equal size, inclined at an angle of approximately 45°.
6 IDENTIFICATION AND LOCATION OF FIRE-FIGHTING EQUIPMENT
Fire-fighting equipment must be identified by a location signboard mounted at theplace where such equipment is located (see Annex 1).
The identifying colour for such equipment is RED.

7 IDENTIFICATION OF ELECTRICAL CABLES AND CONDUCTORS
a) Alternating current (AC):
Unspecified phase brownActive cables Phase R orange
Phase S greenand conductors Phase T violet
Neutral light blue
Earth (ground) : combination of green and yellow
b) Direct current (DC):
Active cables Positive redNegative dark blue
and conductors Mid conductor light blue
Earth (ground) : combination of green and yellow
Existing electrical installations need not to be modified for the sole purpose ofadapting them to the present colour code. However, wherever yellow/green isfound to have been used for an active conductor, the latter must be replacedimmediately with one in the correct colour.
For modifications of existing installations and for new installations, yellow/greenmust be used in all cases for earth (ground) only and for no other purpose. For theother conductors, non-standard colours except yellow/green are permitted for theinsulation, but only if the correct colours are not available and only if sleeves in thecorrect colours are mounted on the ends of the conductors and at junctions.
8 ENTRY INTO FORCE
This code enters into force on the date of publication.
From this date on, new buildings, installations and equipment must be equippedwith safety signs according to the present code. Safety signs not in accordance withthis code must be replaced by new signs as soon as possible, but not later than1 January 1994.
