iv UK Focus - Health & Safety A Revolutionary New Device for Working at Height
The Harken (USA) PowerSeat is the first of its kind, extending working hours and capability, and providing the quality and comfort that people working in hazardous environments deserve. The Harken PowerSeat is a sit on powered ascender with an in- -built manual friction brake descender.
Designed to be used anywhere that rope access is possible, the Harken Power Seat is ideal for industrial maintenance, architectural and construction work, wind turbine and offshore constructions, engineering and inspections, marine and rigging, and also in search and rescue situations.
With the Harken PowerSeat it is possible to work in comfort for extended periods providing up to a 50% boost to productivity whilst saving substantially on operational costs and wage bills. The Harken PowerSeat is simple to operate and has a full 360 degree working area that allows unobstructed work, even in confined areas. The portable unit weighs just 14 kgs so it’s easy to carry around, and is strong, durable and corrosion resistant.
The PowerSeat works with standard approved personal fall arrest systems, and does not replace them. The brake system helps protects from a free fall. In an emergency, the PowerSeat can be evacuated safely and left behind as the operator is already clipped to conventional harness equipment.
The PowerSeat load rating allows for a maximum working load of 273 kg, allowing it to handle a two person load in rescue situations. It is CE certified to Machinery Directive and verified by Bureau Veritas so it meets the toughest safety standards and approvals. Reader Reply Card No. Hydrogen Monitoring Improves Syngas Efficiency
Syngas (synthesis gas) is manufactured from feedstocks containing carbon, such as coal, heavy oil, natural gas or biomass, to produce a mixture of hydrogen and carbon monoxide. The production process involves a number of phases that start with gasification of the feedstock, and efficiency is greatly improved when hydrogen levels are monitored using a new sensor technology that is able to measure continuously without interference from other gases.
Syngas is used in the production of synthetic petroleum, lubricants, fuels for internal combustion engines and as an intermediate in the production of other chemicals.
The gasification phase requires very high temperatures, depending on feedstock and process, which are obtained from an external heat source or by partial oxidation of part of the feedstock to release heat. A purification process then removes impurities such as carbon dioxide, water vapour, methane, sulphur compounds, tar and ash. After which, the proportion of hydrogen and carbon monoxide is adjusted depending on the intended use of the syngas.
Continuous hydrogen measurement provides an opportunity for real-time control of the production process by enabling the operator to make adjustments to ensure maximum efficiency. For example, water may be added to increase levels of hydrogen, or water might be removed to increase the carbon monoxide level. As a result, the operator is able to produce a final product with the correct ratio and to then check that this has been achieved. In the absence of hydrogen measurement, the end product ratio can only be an estimation.
Quantitech (UK) has supplied innovative H2scan hydrogen-specific analysers to the UK market for the last four years. These analysers employ a solid-state hydrogen specific technology based on palladium/nickel alloy that requires no sample gas, reference cell or routine calibration. The sensing material is inherently specific to hydrogen and has the capability to operate in a variety of multi-component and varying-component gas compositions, including tolerance to % levels of hydrogen sulphide and carbon monoxide. Custom conditioning and calibration in contaminant gas streams along with a very precise on-board temperature control loop provides high accuracy and long-term stability. The analysers are also adaptable to conventional or NeSSI type sample systems.

Formaldehyde has Nowhere to Hide with Launch of New Monitor
With formaldehyde present in everything from paper, plywood, MDF, carpets, adhesives, cosmetics, personal care products, disinfectants and cigarette smoke, to name a few, it is impossible to completely eradicate exposure in everyday life. But now, thanks to the launch of Enviro Technology’s (UK) new ground-breaking Formaldehyde Monitor, businesses and industry can now accurately measure levels of this potentially lethal gas.
Formaldehyde can irritate eyes, mucous membranes and the upper respiratory system. Even in small amounts, it can cause serious health problems. Symptoms of low-level exposure include: sore throats, runny nose, headaches and nausea. More seriously, the problems associated with acute exposure include: abdominal pain, respiratory problems, pulmonary edema and it is reported to be potentially carcinogenic.
Widely used by industry to manufacture building materials, significant sources include pressed wood products (such as particle board, plywood panelling and medium density fibreboard used in furniture) made using adhesives that contain urea- formaldehyde (UF) resins.
There is no doubt that reducing levels of formaldehyde in the workplace and in new buildings can reduce risks to human health.
Air quality monitoring specialist, Enviro Technology, is now supplying the new GrayWolf Formaldehyde Monitor (FM-801) for the accurate measurement of formaldehyde levels in offices, buildings – including new builds, factories and industry plants.
The GrayWolf FM-801 is a portable, continuous measurement formaldehyde monitor which uses photoelectric photometry to read the absorbance change that formaldehyde induces in its sensor and then ‘re-zeroes’ between readings to enable continuous monitoring. It is also suitable for quick 30 minute spot checks.
In a nutshell, the monitor provides a fast, simple and accurate measurement of absorption of formaldehyde to indicate levels of the pollutant in the air.
The Face Level Sampling Headset was developed in a research project partly funded by the Swedish Work Environment Authority and carried out at Stockholm University, Sweden.

The GrayWolf FM-801’s sensor cartridges are re- usable providing up to 1,000 tests per cartridge (at low formaldehyde levels) and the monitor is supplied with a mini tripod, 5 sensor cartridges, batteries, AC adapter, GrayWolf’s PC data transfer software ‘WolfSense’ on CDROM or USB, a USB cable and a hard shell case.
Other technical facts about the monitor include: Base unit can be used as independent, simple data- logger with data downloaded to GrayWolf’s WolfSense PC software, The FM-801 can also be interfaced to a GrayWolf AdvancedSense meter, WolfPack monitor or WolfSense enabled WIN7 Tablet/Notebook, FM-801 readings are simultaneous to readings from any other sensors connected to the notes to data files for efficient, reliable documentation of surveys and The measurement range is from <20ppb to 1ppm.
