Car Seals for Lockout of Safety-Critical Valves

“Car seals” are single-use security cable seals, so-called due to their alternative use in sealing railway cars, or wagons. Such car seals can also be used in the safe and effective lockout and isolation of industrial valves. Our Flexigrip 325M car seal is available from UK with unique sequential numbering and 1m length cable for safe and secure sealing of valves.

Car seals perform well as single-use lockout devices to seal a valve in the open or closed position, typically for long durations - for example, to permanently secure a sprinkler system valve. To remove the car seal, a cutting tool is required, after which the cable will splay, ensuring that the device cannot be re-used. This effectively prevents unauthorised use of the valves, where this may be dangerous without appropriate safeguards.

Below is a visual guide to the use of car seals for valve lockout:-

Colour coding is used to indicate the safe working position of the valve, for example green for valves which should be kept in the ‘open’ position, red for ‘closed’ valves, and yellow for ‘throttled’ valves – however, a range of custom colours available upon request: this may be preferred to indicate other important information, such as the substance flowing through pipework.

Car seals for valve lockout come in a standard 1m length cable – but custom lengths are available, to suit particularly large operatus or to seal multiple valves in one operation.

In order to provide safe working practice, a system of working should be implemented to provide a full auditable record of safety lockout. For example, a regularly updated list of safety critical valves should be maintained, recording the following information.

  • Safe position of valve, e.g. open or closed
  • Valve location / department
  • Last inspection date
  • Unique identification number of the car seals

This is to ensure that you meet your responsibilities under national occupational safety legislation. For example, in the UK, the Provision and Use of Work Equipment Regulations 1998 (PUWER), provides for safe working practices - particularly the provision of machinery with appropriate and safe methods of control, and the safe isolation of machinery from all energy sources, as required. Car Seals can act as a suitable tool as part of your health and safety protocols to ensure that your workforce is protected, and that you are in compliance with safety legislation.

If you require another type of solution to suit your particular needs, we do offer other products for valve lockout - our full range is available here.

Identification Tags for Garden Waste Recycling Schemes

Calling all Councils! Our Uniflag big flag tags are perfect for tagging garden waste recycling containers

The implementation of effective waste recycling schemes is a major project for local Councils, who are responsible for the collection of most household waste in each of their respective local wards. The collection of garden waste is often an extra service which Councils may provide to their residents, providing an added benefit to residents in exchange for a yearly licence fee.

It therefore becomes an important consideration to appropriately identify users of garden waste collection schemes, so that local waste collection employees can quickly and easily collect recycling containers or wheelie bins covered under respective local schemes.

Universeal believe that the best way to identify waste containers is by way of printed colour-coded tags, which can be easily applied and removed as each year’s scheme begins and ends. The Uniflag big tag seal offers a cost-effective method of identification and tagging. The large 10x5cm flag head and vibrant colours (such as red, yellow, green, blue and white colours) ensure that the tag is clearly visible on all sizes of item, even in poor visibility and light conditions.



The Uniflag’s robust construction and security features ensure that the tag withstands waste collection environments, and can be customised to suit your local requirements. We are able to print logos, written instructions, dates and telephone numbers on the Uniflag tag, ensuring that important collection scheme information is always attached to the waste container.

The Uniflag is designed and manufactured in our European factory, with quick customisation and colour options. Please give us a call today to discuss your requirements and for a no-obligation sample pack and bespoke quotation.

Industrial Ties and Tags for food-contact environments

Are you using appropriate food-contact safe ties and tags in your production facility?

Tags for use in food environments

The accurate identification and traceability of equipment and production batches within industry is as important to the foodstuffs and pharmaceutical industries as any other. Nylon cable ties, polypropylene seals, paper tags and industrial labels and tape are commonplace across manufacturing and processing industries in order to convey information, protect or warn against dangers, carry production data, and for many other purposes.

However, for the foodstuffs and pharmaceutical industry, the risk of contamination caused by such products is also of concern for the associated risk to all of us as consumers. Risks fall into two broad categories: products made from inappropriate materials, or from the risk of such products being destroyed and incorporated into finished product batches.

Unfortunately, products such as plastic ties and tags purchased by buyers for identification purposes may be manufactured from material which is not safe to be in direct contact with foodstuffs ingested by humans. Alternatively, it is possible that such tags may become detached from their fixing, and become shredded or otherwise destroyed by production processes, resulting in potential undetectable fragments which might find their way into finished products, contaminating them.

Both of these threats should be a major concern for the industry as a whole, and are threats which should be protected against. This is reflected in US and EU law which prescribes materials which are approved for use within safety-critical industries (for example, see regulation 2023/2006/EC on good manufacturing practice (GMP) for materials and articles intended to come into contact with food). FDA and EU Food Contact Approval regulations set out the standards which manufactured products coming into contact with foodstuffs must adhere to, including the migration limits.

In order to minimise risks and to achieve compliance with all of the legislation, BRC standards and implemented HACCP systems (Hazard and Critical Control Points), production facilitites should use appropriate industrial tags incorporated into the production process. It is very important that such facilities use tags and ties which are manufactured from food-contact approved material, and which are also metal detectable.

Metal detectability is a key way of tracing possible contaminants: our food-safe products contain a metal additive or metal component, meaning that even small parts can be detected by industrial metal detection systems during production quality control checks. For example, our plain and printed detectable cable ties contain a metal additive dispersed through the entire tie, meaning that even small fragments can be picked up by most conventional detector systems, and appropriate action taken.

Universeal has three main product ranges which will assist you in achieving compliance: detectable cable ties – available plain or printed for identification purposes; detectable loop tags for batch traceability; and detectable ID tags, which can be written on to record all many of important production information.

Detectable and food-safe products are a key protection against the threats described here, and should be considered by all food and pharmaceutical producers as an important avenue to minimise the risk of hazards to human health.

Tamper-Evident Seals for Keyholding: For when security is key!


keyholding management systems

The safe and secure storage, audit and tracking of keys for critical assets such as building doors, cars, and safety deposit boxes is a major operational challenge for any business. It is crucial that keys can be swiftly identified and an audit history be maintained of all keys held, to whom keys have been issued and where keys are currently located.

Our padlock security seals, also known as “key seals” or “security key tags”, provide an ideal solution to securely identify keys. Our key tag models come with a galvanised wire hasp and polypropylene bodies for strong and robust use. They are suitable for car dealerships, car hire depots, lease vehicle companies, security companies, estate agents and many more types of users.

Our padlock seals are pre-printed with unique sequential numbering and a white face for marking with biro or roller-ball pens. They are ideal for use as car key tags for dealerships to record hand-written vehicle registration numbers against each seal’s unique serial number.

Padlock seals can also be used in conjunction with retention pegs in key management panels and boxes, to ensure that keys cannot be removed without users first inputting their own peg – quickly allowing administrators to see visually which user or department has the relevant key. Additionally, we also offer our SealTrack platform, a service available from our website and which can be accessed from any PC or mobile device. The SealTrack platform allows Universeal customers to issue and record information when sealing keys with a unique padlock seal. For example, a car dealership might record the corresponding vehicle reg. number, the user in possession of keys, and any other application-specific information which might be relevant. This software can be tailored to your specific operation, with customised fields and multiple users. For further information, please contact us about our SealTrack Platform.

Securing the Skies - Security Seals for the Airline Industry

Security seals are a key component in the securing of global aviation logistics, ensuring that aircraft, airports and airline supply chains are secured against the issues of tampering, theft or bad practice. They serve as a means by which an audit history of logistics movements can be maintained so that authorised users might understand where risks under their area of influence might be managed and reduced.

Security Seals in Use

Sealing aircraft doors

Airplane doors should be sealed overnight whilst unattended to ensure that no-one has accessed the aircraft without prior approval. Security labels can be used to seal the seam of the doors in this scenario to ensure that access is notified and recorded. Non-Residue Security Labels cannot be unpeeled or removed without the label delaminating, showing VOID through the surface of the label, but does not leave any unwanted residue on the aircraft itself.

 Sealing air cargo containers

Air freight / air cargo containers are subject to rugged handling, logistics movements, in-flight turbulence, and more. Choosing the right security seal is therefore very important, and seals with sophisticated anti-tamper features and high-pulling strengths only should be used. Universeal UK recommends the application of single-use variable length cable seals in this scenario. Cable seals are much stronger than plastic pull-through seals, featuring pulling strengths ranging from 330+ KgF to 2000+KgF. Cable seals can only be removed using appropriate cutting tools, which prevents access by unauthorised users and other opportunists during transit, and can easily withstand the forces and rigours of airfreight logistics.

 Sealing trucks

Ground operation logistic vehicles, such as trucks and trailers, should be sealed with indicative plastic seals to prevent intrusion once within airport boundaries. Universeal recommends the use of pull-through seals with metal and acetal inserts due to the higher level of sophistication they provide, giving clear evidence of tampering. Pull-through security seals are available in different lengths, pull-strengths and with/without tear-off facilities, to suit the particular requirement. 

 Sealing sacks
Waste or equipment collection bags and sacks should be sealed with printed identification ties or security seals to provide safe transport, recycling/reuse or disposal of all manner of items which are bulk-bagged in the course of main airline and airport operations, or operations ancillary to this. Products can be customised to suit your particular needs – with printing of company name, logo or text; unique sequential numbering and barcodes; as well as packaging to suit operational requirements on the ground.
