IGD are pleased to announce the launch of the TOC-625 Micro Gas Detection System.

Featured

For small systems up to 8 devices with simple I/O requirements this system is ideal. The TOC-625 Micro Gas Detection System Controller interfaces with existing TOC-30A addressable gas detectors and has auto detect and set up features making deployment fast and easy for installers not used to gas detection systems. When detectors are discovered by the system alarm actions and levels are automatically set as detailed in the product literature. As with all IGD addressable gas detectors, supplied detectors are pre-calibrated and store all their configuration on the detector heads making automatic setup after discovery fast and easy.

A Successful Sales Trip to India

At IGD we pride ourselves on how we work closely with clients to provide innovative solutions to their hazardous gas applications. Nothing shows this more clearly that IGD Sales Director Colin Peake’s recent trip to Agra in Uttar Pradesh, India.

Having closely discussed potential new markets with our Indian partner, Respo Safety Solutions Pvt Limited, IGD invested to attend the Federation of Cold Storage Associations of India Seminar in Agra, IGD provide a range of working products for clients to view on the exhibition stand.

The seminar was over just two days and the exhibition stand was visited by over 120 interested companies looking to enhance their cold store facilities with safety and control equipment based on the IGD product range.

IGD can provide both legacy 4-20mA and addressable single cable multi-drop solutions. Respo’s clients were able to identify not only how IGD products can enhance their safety and control functions for Cold Stores and Plant Rooms but especially with addressable solutions provide them at a lower total cost.

Addressable gas detection enables a number of gas detectors and output modules that can drive beacons, sounders or plant control all to be interconnected on a single cable. Forgetting the price of the equipment this installation technique can save clients up to 70% of their install (labour/material) costs; with IGD’s attractive pricing this enables customers to purchase effectively and to save further through simplified installation.

“It was clear that a UK product holds a value of quality and assurance to the Indian market” stated Respo Managing Director Mr Vishal Kaushal “with IGD’s enhanced solutions many clients were shocked and pleased to be able to access these solutions without the expected European premium on cost”.

Gas Detection for Gas Pipe Networks

An Introduction to Gas Distribution

Many flammable gas hazards are present when fuel gas, typically LPG is bulk stored for distribution across a site. Such off grid applications are very common and many clients come to IGD for gas detection solutions to enhance safety in compliance with local requirements.

 The challenge:

 Clients require a system that can mix ATEX certified gas detectors with safe area and domestic gas detectors. Usually the systems must encompass, storage, distribution and use, with data transmitted to central monitoring stations. Other data may be required along with data from gas detectors. This could include totalised gas meter readings, bulk storage tank pressures, vaporiser temperature and more.

 

IGD’s Solution:

IGD are uniquely placed to help clients in this market.. IGD’s addressable gas detection solutions allow networking of up to 32 devices on a cable ‘highway’. Devices can be any mix of gas detectors, control outputs or control inputs. This allows a multiplicity of devices to be easily interfaced together to form a safety and data solution. IGD can supply control panels with one, two or eight cable highways. These can be integrated together hierarchically to build solution networks.

 A solution for a recent clients saw complete integration on one system for the following:

 

  • Tank area monitoring using ATEX addressable TOCSIN 102 Series LPG detectors
  • LPG Tank pressure and Temperature using ATEX addressable 107 Series input nodes
  • Monitoring of double containment pipework using TOC-30A Series LPG detectors
  • Monitoring at point of use using TOC-30A series LPG detectors
  • Monitoring in residences using TOC-10 Series residential LPG detectors
  • Totalising and storing gas meter data using TOC-107 series input nodes
  • Data reporting to host monitoring systems using BACNET

 

A comprehensive safety solution using modern easily deployed networked addressable systems from IGD.

SAFECONTRACTOR LOGO V2

IGD Awarded Safecontractor Accreditation

At IGD we take safety seriously, both in our factory and when on site. When considering which safety accreditation scheme to apply for IGD chose Safecontractor.

Safecontractor is a leading third party accreditation scheme, which recognises very high standards in health and safety management amongst UK contractors.

Under the Safecontractor scheme, businesses undergo a vetting process, which examines health and safety procedures and their track record for safe practice. Those companies meeting the high standard are included on a database, which is accessible to registered users only via a website.

Gaining accreditation through the Safecontractor scheme underlines IGD’s commitment to health and safety. Client-organisations who sign up to the scheme can access the database, enabling them to vet potential contractors before they even set foot on site. These clients agree that, as users of the scheme, they will engage only those who have received accreditation.

IGD are proud to be part of the Safecontractor community helping to build a culture of safety in the workplace.

Guide To Gas Safety In Schools

International Gas Detectors have published their latest White Paper ‘a Guide to Gas Safety in Schools, Colleges and Universities‘. This White Paper is based on two key documents:

  • Building Bulletin 100 (BB100) “Design for Fire Safety in Schools
  • IGEM UP/11 “Gas Installations for educational establishments

BB100 is written with an intention to improve fire safety within schools however many people may not realise that within the document there are specific requirements for gas detection and gas supply control.

The Bulletin also incorporates IGEM UP/11 Gas Installations for Educational Establishments that superseded British Gas IM/25. And further enhances the application of gas safety systems.

This White Paper is written to offer guidance and assistance for designers and surveyors dealing with gas safety in schools, colleges and universities. The White Paper highlights the levels of safety required within educational establishments and explains the solutions available to mitigate against gas hazards.

Ethanol Detection Applied to Crop Storage

Gas monitoring plays an important role in the storage of fruit and vegetables.

During the ripening process fruit and vegetables produce, beside CO2, organic volatile compounds such as ethylene, ethanol, acetaldehyde, acetone and ethyl acetate.

Amongst the most important “ripening” indicators are ethylene, ethanol and acetaldehyde. Monitoring of these gases enables the exact control of the ripening stages and thus an accurate regulation of the oxygen and carbon dioxide content of the storage atmosphere. This can result in a reduction in cost of gas blanketing plus the enhancement of the lifetime and quality of the perishable goods.

IGD Limited can offer a number of alternatives for gas monitoring.

Tocsin 103 Series Detectors

These offer a cost effective monitoring method under T103specific circumstances. When assessing the suitability of the 103 series detector consideration must be given to the temperature and humidity specification. This type of detector is an electrochemical detector, all ethanol detectors of this type will have cross sensitivity to CO. Therefore if CO is likely to be present, typically from diesel or gas powered fork lift trucks, misleading results could occur. If it is possible to utilise this detector type then they offer the advantage of cost and long stable calibration periods. The basic detector provides a linear 4-20mA industry standard output. Addressable types are available allowing networking of detectors onto data highways thus reducing costs and increasing accuracy by eliminating analogue I/O inaccuracies.

Tocsin 102PID

The Tocsin 102PID series detectors are based on Photo-ionisation technology and offer excellent discrimination for a number of gases including Ethanol. Unlike electrochemical 102 PIDdetector types they have no cross sensitivity to other gases which could be present, in particular CO. They are also immune to contamination effects from acetaldehyde. The unit has a local display and provides a linear 4-20mA industry standard output. The units’ main disadvantage for applications monitoring a large number of points is cost and maintenance. A PID detector will require regular replacement of its UV light source.

Tocsin 700 Sampling Systems

If detectors cannot be placed directly into the area to be monitored due to climatic conditions (typical of cold stores) then a sampling system can be considered. These systems have the advantage of central monitoring using high accuracy IR detectors. T700 Sampling Such systems draw a pumped sample from the points to be monitored, sequentially. If tube runs are extended then the time to purge can be long resulting in long cycle times.

With such systems there are pumps and filters to maintain resulting in a high cost of ownership. Sampling systems should only be considered if other alternatives are not possible.

Carbon Monoxide Detection in Car Park Ventilation

Any process where there is incomplete combustion leads to the production of Carbon Monoxide. In enclosed or underground car parks this is typically from petrol and diesel engines. Carbon Monoxide is odourless and colourless, different authorities put maximum safe exposure limits at 30 to 50 ppm and even lower levels have the effect of causing drowsiness.

Having a similar density to air carbon monoxide readily mixes into the atmosphere. As the main area of concern is poisoning due to inhalation normal practice is that:

Fixed detectors need to be mounted at head or operating height. 

Carbon Monoxide has to get to a detector location to be sensed. The further the gas has to travel from its source (an exhaust pipe in this case) to the sensor the more diluted it will become. For this reason any gas detector can only really effectively cover a radius of around 6M.

Gas detectors should therefore be mounted in locations of expected poor ventilation, egress and entry points and areas where vehicles are likely to be queuing with engines idling. There is no point locating detectors on street level exit ramps or fan entries as ventilation will be good at these points.

Domestic Gas Detection

It is crucial to note that gas detectors are as important to home safety as smoke detectors are. A couple whose home blew up in a recent gas explosion have highlighted the importance of having adequate gas detection and have called for gas detectors to be made compulsory in every new home.

There are three main hazards arising from combustible gases within the home; explosion, poisoning and anoxia (insufficient oxygen). The TOC-10 from Sensors Ltd is intended to deal with the explosion hazards of combustible gases. The most likely origins for an escape in gas that could lead to an explosion in domestic premises are the appliances, the connections between appliances and the fixed installation in the buildings.

Carbon monoxide (CO) poisoning is the most common type of fatal poisoning in many countries, every year thousands of people in the UK alone are diagnosed with Carbon monoxide poisoning. Carbon monoxide is tasteless and odourless; however, distributed gas usually has an odour to ensure that the general public may recognise any leakages by a characteristic smell. Most people may detect this odour at quite low gas concentration levels (2% LEL, or less) but some medical infirmities and increasing age may result in a reduction in the sense of smell. A gradually increasing gas concentration may also go unnoticed due to olfactory fatigue.

Domestic Carbon monoxide poisoning can be easily prevented by early detection with the use of household gas detectors which are often easy to fit and use.
