Escape and Rescue Equipment: No Room For Complacency

29th January 2019

Semmco Life Protection Systems breathing escape equipment is fully compliant with the PPE Regulation (EU) 2016/425

Semmco LPS is pleased to report that it’s entire range of hooded life protection devices is fully compliant with the new PPE Regulation (EU) 2016/425, ahead of the deadline in April 2019. 

After April 2019, it is a legal requirement that Respiratory Protective Equipment (RPE) must be compliant with this regulation.[1] The New Approach Directive safeguards that every Personal Protective Equipment (PPE) product on the market will enhance consumer safety. All available RPE must be updated to adhere to the changes to ensure employee health and safety is effectively protected against hazardous or compromised air.

In the UK, a number of workers are killed or seriously injured in confined spaces across a wide range of hazardous industries every year[2]. Danger can arise when workers are suddenly faced with a lack of oxygen or poisonous gases, fumes or vapours enter the confined space.

The end-user of PPE needs to be confident that the Life Protection Systems supplied will protect them against any hazardous or life-threatening incidents that may occur in their working day, which will enable a worker to feel comfortable to work in such environments. 

The CE Marking on a Life Protection System declares that the RPE has been thoroughly examined annually and adheres to the safety standards in Category III (complex PPE) products of the PPE Regulation (EU) 2016/425.[3]

Semmco’s HEAD10, 15 and 30 escape sets offer breathing protection for workers who need to escape confined spaces and hazardous environments, where the breathable atmosphere may not be safe. HEAD escape sets are designed with excellent panoramic vision so wearers can easily see their escape route and has an integral audio-visual alarm that informs the wearer of the amount of breathing time left.

Semmco’s HEAD15 working rescue set is designed to supply a 15-minute duration of oxygen when a worker needs to enter a hazardous area or rescue someone already in a potentially harmful environment, currently used in all UK prisons.

Carl Bennett, Semmco LPS General Manager said: “We are committed to ensuring our Life Protection Systems range are fully compliant, bear the CE marking, and fulfil the essential requirements of the PPE Regulation (EU) 2016/425. Customers can rest assured our equipment meets all the required standards, offers premium protection and when used correctly will keep employees at work protected.”

Semmco to showcase its latest solutions at MRO Middle East 2019

19th January 2019

Demonstrating its local service and leading range of MRO maintenance equipment, the Semmco DWC team will be on hand at MRO Middle East 2019 to discuss the needs of its customers in the region, located at booth 1301. 

The Middle East continues to act as the world’s hub for aviation. Semmco, provides local service through its Dubai office where the team supports its network of Middle East clients.  

Growth in Middle East Aviation Calls for Effective Ground Support Equipment!

Effective MRO maintenance equipment is essential to stay competitive in this thriving market. The region’s investment in technology will see the growing prevalence of digitalisation in aircraft maintenance hangars [1] and the maintenance market will need to adapt quickly.

The Showcase –

Semmco’s range of aviation maintenance access platforms and digital ground support equipment will be on display, including the Nitrogen Trolley with digital panel, and the latest products in the SMART range, the SMART Charge and SMART Check digital tyre inflators with pressure checks.

SMART Nitrogen trolley with digital panel

Adding to the existing range of nitrogen trolleys designed to supply low pressure nitrogen to inflate aircraft tyres or high pressure nitrogen to inflate the struts, this new trolley includes an automatic inflation facility. It is fitted with a digital panel that enables pressures to be pre-set to ensure that the correct amount of gas is always supplied, making the inflation process quicker, simpler and safer. The panel is solar powered but also has a mains charging point for backup if required.

SMART Charge and SMART Check digital tyre inflator/checkers

SMART Charge and SMART Check are Semmco’s latest digital innovation in tyre inflation and pressure checking. These easy to use, robust units give electronic readings, with a calibrated accuracy of +/-2psi and feature a battery powered back light for use on aircraft at night; making the process quicker, easier and more accurate.

Users can choose readings in either bar or psi, and for SMART Charge there is a 350psi safety relief valve to avoid over inflation of aircraft tyres. Both SMART Charge and SMART Check feature a range of tyre valve connectors (8V/12V) to suit all aircraft in the fleet.

High Pressure Nitrogen Portable Charging/Walk-around Kit

This charging kit is designed to provide a quick and simple method of topping up aircraft door systems and tyres.  The high-pressure nitrogen charging kit is lightweight and can be easily handled by one person and is housed in a robust, shower proof carrying bag with a double zip that allows easy access and visibility to the cylinder content gauge, regulator and fill pressure gauge. A low pressure kit is also available for topping up low pressure requirements, for example aircraft tyres.


We look forward to seeing you in Dubai. If you would like to arrange an appointment to meet with one of our sales team at the exhibition, please get in touch on +971 (0)5639 37781 or email

Semmco Ltd Finalist in International Trade Category Toast of Surrey Business Awards 2014

19th March 2014

Semmco was delighted to be a finalist in the International Trade category at the awards ceremony held at G Live in Guildford on 13 March 2014.

Following on from relocation within Surrey, recent investment into the infrastructure and improved internal systems, Semmco now has the potential for future growth, an increasing percentage of which is exported.

Considerable research was undertaken using Embassies, trade missions, attending exhibitions, contacting key people in overseas airlines and obtaining referrals to establish that the need for Semmco’s innovative equipment was not only needed in the UK but in Australia, Singapore and the Middle East and emerging Eurasia. This has resulted in the percentage sales of exported products increasing for Semmco and for expected continued growth.

Exporting is not without its challenges when consideration must be given to designing and manufacturing equipment in accordance with EU regulations for the home market at the same time as ensuring Semmco products have more benefits to the export customers than the overseas competitors provided. One pay off is that any improvements in design in turn help improve the products in the UK market.

Customers such as Lufthansa come to us for bespoke creative designs that are multifunctional and are the next generation of product, so saving them time and money in the long term. Ninety pieces of equipment will be delivered to Lufthansa in Malta over the next couple of years.

Semmco is committed to quality, safety and reliability through innovative designs, while manufacturing cost effective engineered solutions.

Mr Ron Dennis CBE opens new Semmco facility in Woking

17th June 2013

Mr Ron Dennis, CBE, Chairman McLaren Automotive and McLaren Group officially opened the new Semmco high-tech facility in Woking representing the best of British manufacturing.

The 13,000 square-foot engineering facility will assist Semmco to dramatically increase its production and manufacturing capacity to complete orders it receives from around the world for customers such as First ScotRail, East Midland Trains, British Airways, Virgin Atlantic, Lufthansa, Qantas and many more.

Originally based in Wintonlea Industrial Estate, Semmco decided to remain in Woking to retain existing very experienced staff. The decision to move to Goldsworth Park Trading Estate was made to facilitate Semmco’s expansion capabilities and its proximity to the M25. The new facility underscores the exceptional growth of Semmco, where production output has doubled in the past three years.

“The new facility will help assist Semmco’s growth, particularly in the export market which is set to represent 30% of company turnover in the coming years” said Mr Stuart McOnie, Managing Director of Semmco Ltd.

The opening of the new facility in Woking marks another milestone in Semmco’s history, it being the 21st year of the company. Starting with two employees in 1993, Semmco has grown to 29 employees in 2013.

“Although small in comparison to the McLaren Group, our philosophy is the same – innovation, creativity and commitment to excellence. With financial backing from a local bank and continued support from loyal staff, the future of Semmco is bright and the best of British manufacturing is guaranteed.” said Mr McOnie.

Semmco on BBC Breakfast

10th May 2012

Semmco Ltd was featured on the BBC’s Breakfast programme on 8 May 2012 to highlight the Government’s efforts to boost manufacturing and growth.

The recovery from the double dip recession will be driven by UK firms exporting more to countries beyond the European Zone.  There is still a big gap between exports and imports for the UK.  According to the programme, staggeringly we sell more goods and services to Ireland than we do to Brazil, Russian, India and China combined.

The Engineering employers Federation says that while  “8 out of 10 small to medium sized firms would like to export more, most say that they just don’t know how to do it”. 

Semmco is a growing  design and manufacturing company based in Surrey is Semmco who Surrey that has experience in exporting and sells around 25% of its goods overseas.  Semmco’s Managing Director, Stuart McOnie says:

“We make a range of engineering support equipment for the railway industry and aviation market.  The only way we are going to survive as a company so to continue to grow our export share.  Last year we exported 25% and this year our target is 27% of turnover. 

We see there is potential in the Middle East and Russia.  We have also looked at India but we are a little bit anxious about China because effectively we are making a fabricated product and if we ship it to China there is a good chance they may copy it.

The other market which we haven’t really developed yet is Brazil.  We have heard there is a lot of growth out there but it’s a long, slow process and from an initial enquiry it can take up to 18 months to get an order.

We are relocating!

Safe solution with money saving effects - Semmco tops up maintenance efficiency with portable oxygen charging station

7th November 2011

When servicing aircraft between flights, in a fast-paced and busy environment, it is important that ground staff are provided with the correct equipment to carry out their jobs in a safe and timely manner. Regulation stipulates that aircraft O2 cylinders cannot be charged on the aircraft, resulting in the need for the cylinders being sent back to the suppliers to be refilled at great cost and delay.

Semmco provides safety solutions for Britain’s best known holiday and airline providers

28th March 2011

Airline maintenance staff at Thomas Cook and Flybe are frequently involved in the manoeuvre of heavy goods and in particular the transportation of nitrogen and oxygen cylinders. In addition to manoeuvring heavy loads, when the oxygen cylinders that are used to charge the aircraft tyres, suspension and struts run out of gas, the maintenance staff must pass through security to take delivery of new cylinders from the supplier outside the security gates.  In order to reduce the amount of manual handling, save time and consequently save money for line maintenance teams, leading UK airlines Thomas Cook and Flybe turned to Semmco to help develop an innovative product that complies with Health and Safety legislation to protect the workforce and enhance their productivity.

Semmco - UK engineering company beating the downturn

14th July 2009

UK engineering company, Semmco, wins contract to supply the new HEAD 15 Cell Snatch Rescue Equipment (CSRE) to the UK and Irish Prison services.

Semmco, has beaten off competitors to supply their latest product, HEAD 15 to the UK and Irish Prison services.

Manufactured entirely in the UK, the Semmco unique HEAD 15 chemical oxygen set is an easy to don, one-size-fits-all model. The working set, known within the Prison Service as CSRE, gives prison staff 15 minutes of respiratory protection when dealing with cell fire incidents.

The lightweight, hooded oxygen set replaces the short duration breathing apparatus (SDBA) which has been used across the prison services for the past 15 years. The training requirements for the CSRE are less complex than those of the SDBA, making the product easier to use. Added to this the HEAD 15 working set can be stored for up to six years without maintenance, making it a cost-effective option in the long term.

Press Launch for bmi Tail Dock at Heathrow

25th September 2008

Semmco recently unleashed its new tail docking system (pictured), which has already saved award-wining UK airline bmi the cost of a plane over 12 months of use, and improved safety for engineers working at height.

At a lavish ceremony held at the Jurys Inn Hotel, Heathrow Airport – and later inside bmi’s Heathrow hangar – Semmco Managing Director Stuart McOnie unveiled the impressive-looking structure to luminaries from the Press and airline industry.

The system, that literally encases the aircraft tail, consists of access steps and a platform, enabling engineers to work at four different height levels, from 8 to 30ft. Built on a steel base, the aluminium construction of the frame and platform makes the tail dock light enough to be easily manoeuvred to suit varied maintenance requirements.

22 August 2008

HSE used Semmco access steps as an example of improved safety on maintenance of Virgin Planes. "The steps have now been in use for 2 years. They are very well liked by the engineers and are finding other uses such as working under the main wings and accessing the engine spar area."

"These steps resolved the issue of the cargo hold access however we still had to solve the problem of working under and around the engine. This time we showed the supplier the problem and they came up with a design and manufactured a set of trial steps. We put the steps on trail and this included obtaining written feedback from the engineers."
