CSD were contracted to supply and install the HR Conduit Sleeves and NOFIRNOfirestopping system at the site. The project had a requirement to maintain a 60-minute fire integrity requirement for all cableand pipeentry penetrations passing through Cross Laminated Timber (CLT) panels used within the wall construction.
The selected solution for the CLT wall type was a HR-frame sealed withNOFIRNO firestopping systems.
NOFIRNO | HR Frame | Penetration Systems
Facility Fireproofing
There were various challenges when it came to designing and installing a solution suitable for sealingthe pipe and cable penetrations through the CLT wall panels. The solution had to ensure that the 60-minute fire rating was maintained when the panels were penetrated by any service passing into each unit. During CSD’s installation onsite, we worked alongside the M&E contractors to ensure that completion of each unit could be signed off on time.
Outcome of using Penetration systems
The penetration seal design with HR-frames and with NOFIRNO penetration seal system achieved fire resistance of more than 60 minutes. All openings were successfully sealed by CSD’SÂ installation team and the project handed over on target.
Nofirno Penetration System
The NOFIRNO cable and pipe penetration system comprises of only a few components.
A correctly fitting NOFIRNO cable sleeveis placed around each cable, any free space around any services is packed using NOFIRNO multi sleeves before completing the seal with a 20mm layer of NOFIRNO sealant at each end of the penetration.
To ensure the NOFIRNO Sealantadheres correctly, the areas where the sealant is to be applied should be clean and dry before application. Furthermore for example any pipes or cables, and any frames or the building structure.
The system will provide a fire rated, water and gastight sealand has been shown to provide protection for a period of at least 50 years.
HR Penetration fRAMES
CSD’s HR penetration frames are designed for use in composite or sandwich panels. They allow cable or pipes to penetrate the panel. CSD’s NOFIRNO Penetration Sealing System will ensure the fire integrity of the panel is maintained.
The HR frames are available in a range of circular and rectangular sizes. It can be easily adjusted to suit the thickness of the panel.

Thorne & Derrick are Approved Distributors for CSD Sealing Systems – we have specified and distributed their products across numerous onshore and offshore substation projects.
CSD Technical Services were recently contracted to carry out water and gastight sealingof cable entry points.
This was on a DNO substation at a council maintenance and storage depot. This was also a part of an action plan to reduce carbon emissions across the site.
Using CSD’S NOFIRNO Duct Seal System distributed by Thorne and Derrick, it has successfully sealed all entry points, helping to prevent any water or gas ingress in the building.
Completing the seal with a 20mm layer of NOFIRNO sealant will provide a technically advanced and high performance duct seal. View the complete range of CSD Sealing Systems to protect against damage caused by water ingress, gas spread or fire/flame to cables and ducts.
NOFIRNO | Substation Sealing | CSD The NOFIRNO Duct Seal is designed to provide simple and effective long term building entry sealing protection. The system can be used in new build projects or in retrofit applications to replace existing failing seals. It can be installed directly into concrete openings, plastic ducting or into any existing transit frames.
Substation Duct SealingÂ
The site remained operational throughout the installation, with CSD working alongside and in partnership with other contractors and existing site workers. The NOFIRNO Duct Seal Systemwas the selected solution for sealing the entry points.
Outcome of using the NOFIRNO Seal System
All entry points into the substations were successfully sealed using CSD’s NOFIRNO Duct Seal System to prevent any water or gas ingress within the building.
This was to ensure the site remained operational. The openings within the control room which consisted of 37 x 160mm cable ducts and a 1 x 690mm x 900mm cable entry, was sealed along with a 1 x 230mm x 430mm cable entry in the DNO building.
A second visit to site was made to remove 1 x 150mm installed seal following the installation of an additional cable. This seal was then resealed using the NOFIRNO Duct Seal System. The client feedback was very positive, and they will be looking to use CSD for future projects.
NOFIRNO Duct Seal System
The NOFIRNO Seal System comprises of two components; 60mm rubber NOFIRNO multi-sleeves which providing the cables with support, ensuring separation.
It helps provide a backing for the second component which is a 20mm layer of NOFIRNO Sealant. To ensure the NOFIRNO Sealant adheres correctly, the areas where the sealant is to be applied should be clean and dry before application.
For example the cables and any frames and structures. The NOFIRNO multi-sleeves are then installed providing cable separation and a firm backing for the NOFIRNO Sealant layer.
NOFIRNO duct seals consist of rubber multi sleeves which are in bonded strips of 10 sleeves and a high quality silicone based sealant which are quicker and easier to install than the CSD standard RISE duct seals.
The bonded sleeves can be easily torn off for filling smaller gaps and using cutting tool sleeves can be quickly slit to allow fitting around cables ensuring cable separation – NOFIRNO duct seals are also used to pack the free space, providing a backing for the application of the cable sealant.

Safety is a top priority in any industrial setting, and one crucial aspect of ensuring a secure working environment is the installation of heavy-duty Dropped Objects Prevention Safety Nets. These robust nets provide an effective secondary solution to catch objects in case the primary fixings fail.
The primary purpose of safety netting is to prevent injuries and protect workers and equipment from falling objects. Safety nets act as a vital secondary measure, providing a reliable barrier to catch objects that may accidentally fall or be dislodged from primary fixings. By installing heavy-duty safety nets, industries can significantly reduce the risk of accidents, minimise property damage, and enhance overall workplace safety.
Thorne & Derrick stock and distribute an extensive range of Confined Space Entry Products and Equipment to mitigate potentially life-threatening dangers such as flammable gases, dangerous chemicals and other hazards – this ensures people are safe at all times and also provides the correct rescue equipment to meet the legislative requirements.
In this blog, we will explore various examples of safety netting installations, along with the assembly instructions for safety nets, highlighting the importance and purpose of these essential safety measures.
Safety netting comes in different forms, tailored to meet the specific needs of various industries. One prominent example is the stainless steel net, commonly used as a dropped objects prevention safety net. These nets are designed to catch falling objects, preventing potential hazards and protecting workers and equipment below. Stainless steel nets offer exceptional strength, durability, and resistance to corrosion, making them ideal for industrial environments
Safety Net Rolls: These versatile nets come in rolls, making them easy to transport and install. They are ideal for covering large areas quickly and effectively, offering reliable fall protection and containment.
Safety Net Fit-to-Size: custom-fit stainless steel nets are available in situations where precision is paramount. These nets are tailored to specific measurements, ensuring a perfect fit for any industrial setting. They provide maximum safety without compromising on aesthetics or functionality.
Safety Net Roll
The Safety Net Roll is cut in smaller sections with simple hand tools and wrapped around equipment at height. A steel lanyard is used to attach the net to a structure as a secondary retention method to prevent dropped objects. The Safety Net Rolls are suitable for onshore and offshore conditions and are chemical treated.
To prevent objects from falling from height the safety nets are wrapped around the objects. The size of the object determines the size of the Safety Net Roll required. A strong lanyard is supplied to weave through the netting and wrap and lock the ends of the safety net to the solid structure. This secondary retention method is commonly applied to protect the lives of the workers and pedestrians.

How do you install a safety net?
Proper installation is crucial to ensuring the effectiveness of safety nets. Here are some key steps to follow when installing industrial safety nets:
Planning and Assessment: Begin by conducting a thorough assessment of the area where the safety net will be installed. Identify potential hazards, determine the required dimensions and strength of the net, and assess the attachment points.
Preparation: Prepare the area by removing any debris or obstacles that may hinder the installation process. Ensure the attachment points are secure and capable of withstanding the load.
Net Assembly: Follow the manufacturer’s instructions for assembling the safety net.
Attachment Points: Depending on the specific installation requirements, safety nets can be attached to existing structures such as beams, walls, or specially designed frames. Ensure the attachment points are robust and capable of supporting the net’s load.
Tensioning:Proper tensioning is essential to maintain the integrity of the safety net. Carefully adjust the tension to ensure a taut and secure installation. Be mindful of the net’s sag, as excessive sag may reduce its effectiveness.
Testing and Inspection: Once the safety net is installed, conduct thorough testing to ensure its stability and load-bearing capacity. Regularly inspect the net for any signs of wear, damage, or degradation, and replace or repair as necessary.
Conclusion
Industrial safety nets, particularly stainless steel nets used as dropped objects prevention measures, play a critical role in maintaining a safe work environment. By understanding examples of safety netting, following proper installation procedures, and recognising the purpose of safety netting, industries can effectively mitigate potential hazards and ensure the well-being of their workforce. Implementing these heavy-duty safety measures demonstrates a commitment to safety and provides peace of mind to employees and employers alike.
Remember, when it comes to safety, investing in reliable safety netting is a worthwhile endeavour that pays dividends in accident prevention and overall workplace safety.
FAQ – Dropped Object safety Nets
What Are Safety Nets?
Safety nets for fall protection are generally used at high-rise building construction sites in order to prevent objects from falling on the worksite. These nets are different from oil nets or other safety net systems in that they are a form of secondary protection in case the primary safety fails. We have two options available. One option is a safety net roll, which can be cut and used according to what size is needed. Another option we offer is custom sized nets, which is implemented fast as it requires no modification and is made for the object itself.Â
What Is Secondary Retention?
Safety Nets Fit-to-size are used for secondary retention. It secures, encloses and tethers overhead fixtures to prevent dropped objects to the work floor when its primary attachment (or installation bracket) fails.
Why Dropped Objects Prevention?
The accidental dropping of toolsand equipment poses a safety threat to workers operating at elevated heights. It is therefore important to take precautionary measures to reduce the frequency of such accidents. Tools, equipment and mounted objects in an elevated location have the potential to fall due to movement.
These nets are designed to protect employees from severe injuries in a wide range of working environments. The dropped object prevention safety net will catch the equipment at height when brackets corrode or connections to structure fails (e.g. impact by crane, fatigue, etc). The nets are designed for onshore and offshore installations.
Best practices & recommendations
Portable Equipment
All portable equipment used where there is a risk of the equipment falling to an underlying level must be secured against being dropped
Carrying pouches must always be used for radios and any other portable equipment without certified securing points
Locks on pouches must have a double securing mechanism to prevent unintentional opening
Belt clips that allow equipment to become detached when turned 180º should not be used
Belts with snap fasteners are not suitable for securing equipment at height
Battery compartments and covers on portable equipment must be secured to prevent internal components from falling.
Remember even small items falling from significant heights can cause injury and distractions. Ensure all personal equipment (tally books, pens, calipers, cameras, water bottles etc.) is secure in a fastened pocket or carry pouch. If the item is not required for the task, do not carry it at height – leave it at ground level.
Securing Tools >5kg / 11lbs
All use of heavy tools and hand-held machinery where equipment may fall to an underlying level must be risk assessed
All heavy tools and hand-held machinery used at height must be secured against being dropped, both when in use and while being transported
Securing points for tools and machinery must be in place above the work site, attached to the surrounding structure, not to scaffolding
Tools heavier than 2kg should not be secured to the body, secure them to the adjacent worksite structure
One piece sledge hammers (forged construction with secured head) should be used at height
The attachment points / devices on tools shall be documented and all securing wires inspected in accordance with the manufacturers recommendations
The securing wire must be as short as possible to reduce shock loading effect
Energy absorbing lanyards and tethers can stretch beyond the safe calculations or drop distance, therefore fixed securing wires should be used on heavy tools at height, according to the work environment
Only certified lifting equipment shall be used as securing devices (where appropriate)
Tools used at height should be checked out / in (see Page 54) to ensure that nothing is left behind.
Securing of Personnel
The choice of equipment to be used must be made after evaluating the work place environment
Established control procedures must be followed before, during and after use
Anyone using personal protective equipment against falls from height must have documented training (including rescue method training)
Nobody shall work alone or unattended when using fall arrest equipment
Everyone involved in the work scope must have sufficient training and awareness of the equipment and safety procedures
A ‘Buddy’ check of all fall arrest, rigging and other equipment must be carried out
The necessary rescue equipment and trained personnel must always be available at the workplace
Fall arrest equipment must have CE approval, incorporate an anti-trauma safety device and comply with an accepted standard
The equipment shall be checked EVERY TIME before use and must be checked at least every 6 months by a competent person
The date for next inspection must be clearly shown on the equipment
The anchor point for suspension must be rated to 5000 lbs (22kN) – OSHA.
