SUBJECT : 32nd WEEKLY TOOLBOX MEETING (SAFETY IDENTIFICATION & COLOR CODING)
A. Objective :
To introduce to the workers that safety identification and safety color coding in the Saudi ARAMCO
Facilities is a must in order to identify potential hazards and alleviate fire and safety concerns.
B. Introduction :
Color is one of the most effective on-the-job safety devices ever used, and all workers should be
familiar with the color plan and color coding used by their companies.
If hazards are identified by a good, consistent color system, and proper orientation and familiarization
procedures are followed to acquaint all workers with the color-hazard relationship, the recommended
color code system must be followed.
All workers should become thoroughly familiar with the color coding used in your work areas and it’s
important that new workers or veteran workers with a new job be acquainted with the system of color
coding.
C. Standard Color Code System to Identify Related Hazards (International Standard):

1. Red = for fire apparatus and equipment, safety containers for flammables and emergency devices
like switches for emergency stopping of machinery, stop bars and buttons.
2. Orange = for potentially dangerous parts of machinery or equipment that may cut, crush, shock, or
otherwise injure a person.
3. Yellow = the color of caution; for physical dangers, such as slipping, tripping, falling, caught
between and striking against hazards.
4. Blue = a caution color; for warning against the use or movement of equipment being repaired or
worked on, or the starting of equipment.
5. Green = the color of safety; for First Aid Equipment locations.
6. Purple = the basic color for warning of radiation hazards.
7. Black, white, or a combination = for designating and helping to control traffic movement, and for
aisle markings, housekeeping areas, and similar areas.
D. Saudi ARAMCO General Requirements (REF. SAES- B-067):

1. Pipes, vessels, valves and related structural supports shall be painted a neutral background color
such as aluminum, gray, or black which will not detract from the high visibility of the safety colors set
out for this specification ( SAES-H-001)
2. Safety signs for gas cylinder storage areas, gas cylinder labeling and marking requirements,
including lettering in Arabic and English for gas cylinders, shall meet (CU 15.4) of the Saudi Aramco
Material Instruction Manual, including all industrial, medical, laboratory and aviation bottled gases.
3. Utility stations in Plants : the water, steam, air and nitrogen lines shall be marked and color-coded as
specified in SAES-L-042 “Plant Utility Stations”.
4. Aviation Fuel Systems : color identification for aviation fuel system piping and accessories
including valves, fittings, pumps, and switches shall be as per API STD 1542. The color of jet fuel
system accessories shall be gray for Jet A-1 and yellow for Jet B.
5. Bulk Plant product specification for the transfer points at loading and unloading facilities such as
loading and unloading racks, associated pumps and tank storage related to bulk plant operations shall
use color identification as listed in Table 1 ( as shown below).

5. New Safety sign symbols and colors, shall meet ANSI Z535.1 to Z 535.5 including safety accident
prevention tags for temporary hazards. The colors assigned for Safety are; red, green, yellow, yellow &
black, orange, blue, and white, and this color criteria for safety colors shall meet the ANSI standard.
(Safety Color Code-ANSI-Z535.1, Environmental & facility Safety Signs-ANSI 535.2, Standard
for Criteria for Safety Symbols-ANSI-Z535.3, product Safety Signs & Labels-ANSI-Z535.4, &
Standard for Accident Prevention Tags(for Temporary Hazards)-ABSI 535.5).
a. Safety Red = shall be used as the color indicator for fire protection equipment and piping, as well as
emergency stop push button devices. Safety red shall also be used for background of “Danger” and
“Stop” signs, “Emergency Room” signs and arrows, and “Emergency Shutdown” signs, and the
lettering shall be in Safety White.
b. Safety Green = shall be used as the background color indicator for locations of emergency Safety
equipment, such as First Aid Equipment, Breathing Apparatus, and Safety Instructions.
c. Safety Yellow and Yellow & Black = shall be the color indicator for physical and radioactive
hazards, such as manhole covers and any associated concrete structure that may protrude (for
communications manhole cover), warning and caution signs shall have black lettering on safety
yellow background, physical hazards such as stumbling and tripping hazards, concrete supports at the
base of stairways or ladders, passageway pinch points, unguarded edges, barricades including access
road overpass railing in plant areas, safety yellow and black stripes shall be used stripes 100mm wide),
and location of plant public address system shall be marked by safety yellow stripes on safety black
background.
d. Safety Orange = shall be used as the color indicator for the following;
1. Orange paint, orange dye, and orange marker tape shall be used to identify buried concrete
communications ducts and manhole cover.
2. Marine related life safety devices such as escape capsules and flotation work vest shall be orange in
accordance with international convention.
3. Isolation valves and associated instruments shall be painted safety orange.
4. Inlet and outlet block valves for pressure relief valves shall be painted orange.
e. Safety Blue = shall be used as the color indicator for potable water (sweet water and domestic raw
water). Above ground potable water piping in plant areas shall be painted blue.
Other Standards (reference only):
API STD 1542 = Airport Equipment Markings for Fuel Identifications
ANSI/CGA C-4 = Method of Marking Portable Compressed Gas Containers to Identify the Material
Contained.
ANSI/CGA C-7 = Precautionary Labeling and Marking of Compressed Gas Containers
BS 381C = Colours for Identification, Coding and Special Purposes
RAL = German Specification for Colors (RAL)
FS 595B = Colors used in Government Procurement (USA).
NFPA 55 = Storage, use and handling of Compressed and Liquefied Gases in Portable Cylinder
Always Remember:
Color coding is used extensively in certain piping systems to indicate to workers what the line
contains, such as water, steam, electricity, high pressure, air, gases or chemicals particularly at the
Saudi ARAMCO Facilities.
