Strategic marking improves safety and operational reliability
Effective industrial marking is about far more than regulatory compliance and safety signs.
It supports:
Operational reliability
Asset traceability
Efficient maintenance
Workplace safety
Effective asset management
When pipes, equipment, and technical installations are clearly identified, the risk of the following is significantly reduced:
Operational errors
Unplanned downtime
Production disruptions
Personal injury
Inefficient maintenance procedures
TG Technology develops integrated marking strategies that combine international standards, visual communication, and technical documentation into one consistent solution.
Key requirements and standards for industrial facilities
“Regulatory requirements for pipe marking
Occupational safety regulations require all visible pipe systems carrying hazardous substances to be clearly identified with the appropriate hazard symbols and media identification.
Marking must be positioned visibly and at suitable intervals in accordance with applicable regulations.”
“Standard Operating Procedures create consistency
Standard Operating Procedures (SOPs) establish consistent marking, documentation, and maintenance procedures across facilities, departments, and projects.”
“International standards reduce operational risk
Standardised colours, symbols, and flow markings enable employees, contractors, and maintenance personnel to identify systems quickly and work more safely and efficiently.”
Advice, SOPs, and industrial marking
-
TG Technology develops Standard Operating Procedures (SOPs) for industrial marking and identification systems.
Every project begins with a detailed consultation to ensure the solution is tailored to your:
Production processes
Process flow
Maintenance strategy
Safety requirements
Technical environment
We work in accordance with Danish, European, and international standards to deliver consistent solutions that integrate seamlessly across facilities, installations, and documentation systems.
Benefits of SOPs
Consistent industrial marking
Improved operational reliability
Faster maintenance
Fewer operational errors
Better documentation
Scalable solutions
-
Correct identification is essential for safe operation during inspections and maintenance activities.
TG Technology assists companies with:
Assessment of existing marking systems
Updating TAG systems
Standardisation of signs and identification
Verification of installations
Optimisation of visual safety
Our installation teams work in accordance with recognised safety and installation standards to ensure every project is completed to the highest professional standard.
We also design every solution with future expansions, new installations, and system modifications in mind.
-
Legislation and statutory regulations are legally binding requirements issued by public authorities.
Standards, on the other hand, provide technical guidance and recognised best practices that improve:
Consistency
Quality
Safety
International compatibility
Many standards also gain indirect legal significance when they are referenced in legislation or used to demonstrate compliance with recognised industry practice.
TG Technology actively advises on, develops, and implements both Danish and international standards.
International standards and industrial safety
International standards play a vital role in improving safety, operational reliability, and consistency across industrial facilities.
TG Technology advises companies on selecting, implementing, and applying recognised standards for industrial marking, pipe identification, and safety signage in both new and existing installations.
-
DS 134 and DS 735 have formed the basis for pipe marking in Denmark for many years.
TG Technology has developed its own practical guide based on these standards, making it easier to implement consistent and compliant pipe marking across industrial facilities.
-
ISO 7010 defines internationally recognised safety signs and symbols, creating a consistent visual language for workplaces around the world.
The standard includes:
Warning signs
Prohibition signs
Mandatory signs
Fire safety signs
Emergency escape signs
Why ISO 7010 matters
Consistent safety signage reduces confusion and helps prevent accidents by ensuring that employees, contractors, and visitors immediately recognise important safety information—regardless of language or location.
-
DIN 2403 is a recognised German standard for identifying industrial pipe systems.
The standard uses colour coding, media identification, and flow direction arrows to improve operational safety and simplify maintenance.
DIN 2403 is widely used in:
Process industries
Energy and utilities
Pharmaceutical manufacturing
Food processing
Technical installations
TG Technology manufactures FLOWMARK pipe markers in accordance with DIN 2403 as well as customer-specific standards and SOPs.
FLOWMARK can be customised with the required colours, symbols, media descriptions, and flow arrows.
Benefits of DIN 2403
Clear identification of pipe contents
Improved operational safety
Faster servicing and maintenance
Consistent marking across facilities
Supports documentation and compliance
-
DURATAG is TG Technology's heavy-duty pipe marking system, developed for demanding industrial environments.
The durable PVC marker is protected by a UV-resistant coating and mounted in either an aluminium or AISI 316 stainless steel frame using PVC-coated stainless steel cable ties.
DURATAG is designed to withstand:
Chemicals
UV exposure
Mechanical impact
Offshore environments
Process industries
Healthcare and pharmaceutical facilities
The system provides excellent readability, even on small-diameter pipes, and includes space for GHS hazard symbols.
All DURATAG markers are manufactured with both left- and right-hand flow direction options, ensuring fast installation and correct identification.
The system complies with applicable regulations and recognised industry standards.
All DURATAG solutions are supplied with a 3-year warranty.
-
ISO 20560 is an international standard developed to create a globally consistent system for safety information on above-ground pipes and tanks.
The standard improves operational safety by ensuring clear identification of pipe contents, flow direction, and potential hazards throughout industrial facilities.
The standard covers:
Media colour coding
GHS hazard pictograms
ISO 7010 safety symbols
Flow direction
Process information
Design principles
Why ISO 20560 matters
A consistent visual identification system reduces operational errors, improves maintenance efficiency, and enhances safety in complex facilities with multiple process systems and international contractors.
-
ISO 14726 defines colour coding for identifying pipe systems on ships and offshore installations.
The standard provides:
IMO-compliant pipe identification
Clear identification of pipe contents such as ballast, fuel, and lubricating oil
Optional media descriptions and flow direction arrows
Benefits
Provides crews and maintenance personnel with a clear overview of pipe systems while reducing the risk of operational errors.
-
ISO 16069 specifies how complete escape route guidance systems should be designed and implemented using both electrical and photoluminescent guidance systems.
The standard includes:
Guidance lines
Door frame marking
Stair and obstacle marking
Evacuation plans (ISO 23601)
Why it matters
During a fire, smoke can significantly reduce the effectiveness of conventional emergency lighting. Low-level photoluminescent guidance systems improve orientation and support faster, safer evacuation.
-
ISO 15370 specifies requirements for Low Location Lighting (LLL) systems on ships and offshore installations.
The standard covers:
Approval, installation, and maintenance requirements
Electrical and photoluminescent guidance systems
Installation up to 300 mm above floor level
Offshore drilling units
Benefits
Improves evacuation safety when smoke limits visibility of conventional emergency lighting.
-
DS/EN ISO 7396-2 specifies the requirements for the safe design, installation, testing, and operation of medical gas pipeline systems used in hospitals and healthcare facilities.
The standard includes:
Design and installation requirements
Distribution of oxygen, vacuum, and medical gases
Monitoring and alarm systems
Documentation and testing procedures
Patient safety and operational reliability
Why it matters
Medical gas systems are critical to patient care. Even minor failures can have serious consequences. Compliance with DS/EN ISO 7396-2 helps ensure consistent quality, operational reliability, and patient safety.
-
ASME A13.1 is the leading American standard for identifying industrial piping systems.
The standard specifies:
Colour coding
Pipe content identification
Flow direction arrows
Hazard classification
Benefits
Faster identification
Improved safety
More efficient maintenance
