Laser & Plasma Cutting

by DiversiTech     based in Montreal, QUEBEC (CANADA)

Laser & Plasma Cutting fumes are Unbreathable. Using laser or plasma cutting equipment on either metals or plastics introduces several known carcinogens, such as fused silica and ethyl acrylate, into the air. Occupational Health and Safety organizations recommend reducing personal exposure to the lowest level feasible. Hand held plasma cutting provides metalworkers with a quick and fast way to cut large sheets of metal material. However, plasma and oxy cutting generate a large amount of sparks, slag and fume which can contain different pollutants depending on the type of material being cut. Diversitech's line of downdraft tables incorporating the plasma cutting kit are designed to extinguish the sparks and slag, using heavy duty steel bar grating and a gravel filled baffle tray while the blower pulls away all of the toxic plasma cutting fumes. When considering how to capture and filter the fumes generated from large CNC plasma cutting and laser cutting machines, a large central dust

Mercury monitoring for measuring mercury content in hair

by Tekran Instruments Corporation     based in Knoxville, TENNESSEE (USA)

Measurement of mercury content in hair is a convenient technique to estimate dietary exposure without having to handle tissues or bodily fluids. As the mercury present in hair is comprised of different mercury species, full speciation of the compounds is needed for complete understanding. Environment Canada published a technique where treating a basic digestion with Cd2+ in the presence of cysteine allowed analysis of inorganic mercury and total mercury using a Tekran 2600 System. Methyl mercury was then calculated by difference. Tekran has over 18 application notes available for Tekran 2600 users.

Gas Detection Solutions for Sour Gas

by Boreal Laser Inc.     based in Edmonton, ALBERTA (CANADA)

The sour (H2S) content of hydrocarbon fields worldwide is increasing, and many natural gas fields have very high H2S – sometimes in excess of 50%. H2S is extremely dangerous because, although people can smell it at low levels (about 5 ppb) it does not smell much worse at the exposure limit value of 10 ppm or at potentially fatal levels in excess of 100 ppm. Therefore smell is an unreliable means of determining dangerous levels. Existing H2S point sensors are maintenance intensive, slow to respond and provide limited coverage. Most H2S sensors do not work reliably in hot or cold weather, or in humid marine environments.

Noise monitoring solutions for sound power

by Brüel & Kjær Sound & Vibration Measurement A/S     based in Nærum, DENMARK

Noise emission values are increasingly becoming marketable items for machines, equipment and appliances - low noise emissions directly relate to lower noise exposure for product users and bystanders. Retail customers, both private and corporate, appreciate this relationship and are, therefore, more aware of noise emission declarations on goods when deciding their purchases.

APHA Color #3020

by Guided Wave Inc,     based in Rancho Cordova, CALIFORNIA (USA)

Measurement of APHA color either on-line or in a laboratory setting using a photometer. Background: APHA is sometimes referred to as the Platinum Cobalt (Pt/Co) or Hazen scale. Also referred to as a “yellowness index”, the APHA color scale is a common method of comparison of the intensity of yellow-tinted samples to assess the quality of liquids that are clear to yellowish in color. Originally developed to determine the purity of municipal water supplies, it is now used as a metric for purity in the water, chemical, oil, plastics, and pharmaceutical industries. APHA color quantifies the appearance of trace amounts of yellowness, which is a visual indicator of product degradation due to exposure to light or heat; the presence of impurities and negative effects of processing. As such APHA color is often used as a product release specification. APHA is a single number yellowness index. The units are based on a dilution of a 500ppm solution of PtCo.

Gas monitoring instruments and systems for print factories

by Gasmet Technologies Oy     based in Helsinki, FINLAND

Typical modern printing processes utilize solvent-based dyes. The evaporation of the dye solvents into the ambient air during the printing process may expose the workers to various chemicals. Depending on the type of solvents in case, the solvents have different long term exposure limits, which should be obeyed. Component specific measurements are necessary to protect the workers from exposure while avoiding unnecessary interruptions to the printing process from false alarms.

Low frequency noise analysis using XL2

by NTi Audio AG     based in Schaan, LIECHTENSTEIN

The Data Explorer PC software for the XL2 Sound Level Meter now includes a series of professional tools for detailed analysis of low-frequency noise (LFN). The graphical representation of time varying frequency components offers an efficient process for identifying the presence and level of LFN. Also the associated high quality audio recording supports further correlation with the objective measurement data. The new features are particularly useful in the calculation of immission levels which is defined as the cumulative noise energy to which an individual is exposed over time. Exposure to low-frequency noise over extended periods can lead to a range of health problems including cardio vascular disease, insomnia and depression. The sources of low frequency noise can often be attributed to electricity sub stations, chiller plants and incinerators with continuous noise at frequencies below 200 Hz. XL2 Sound Level Meter records all Data Measuring LFN requires a class 1 sound level meter

Gas monitoring instruments and systems for anesthetic gases

by Gasmet Technologies Oy     based in Helsinki, FINLAND

The anesthetic gases and vapors which leak into the indoor atmosphere during medical procedures are considered waste anesthetic gases (WAGs). The exposure is of relevance to thousands of professionals in hospitals, operating theaters, patient recovery rooms, dental offices, and veterinary clinics around the world, who may be continually exposed to the waste anesthetic gases during their workday. Typical gases of concern include nitrous oxide N2O and several halogenated compounds in vapor form, such as sevoflurane, isoflurane, enflurane, halothane, desflurane, and methoxyflurane. Short-term exposure to these gases may lead to several symptoms, such as dizziness, headaches, fatigue, nausea. Long-term exposure to some of the anesthetic agents may result in sterility, birth defects, cancer, and liver and kidney disease.

Gas detection for the winery and brewery Industry

by Crowcon Detection Instruments Ltd - a Halma company     based in Milton Park, UNITED KINGDOM

Once an archetypal example of manual production, the winery and brewery industries now incorporate sophisticated processes to ensure high quality levels and efficient output. In some cases traditional approaches have simply been scaled up or put under more stringent monitoring, whilst in others innovations such as nitrogen-pressurised canning have been introduced. However, whichever approach has been followed there is also a growing realisation of the gas hazards that are associated with both new and old processes, and the need to protect workers from toxic gas exposure and asphyxiation risks.

Air monitoring equipments for workplace and personal exposure monitoring

by Gradko International Ltd     based in Winchester, UNITED KINGDOM

Many occupations involve the use of hazardous substances or processes, where pollutants may be ingested, inhaled or absorbed through the skin. General ambient pollutants can also have health implications in otherwise non-hazardous workplaces. Occupational exposure limits regulate many pollutants based on an eight-hour working day. Personal exposure assessments can be made over an eight-hour period (Time Weighted Average (TWA) exposure) using our simple to use monitoring equipment.

Sound Instrumentation for Measuring Sound

by Norsonic AS     based in Lierskogen, NORWAY

What is the difference between sound and noise? Clearly more than the loudness only. Although an aircraft is very noisy, a mosquito at night-time can be more than enough to spoil a good night`s sleep. Instead of looking at the loudness only as a criterion for the degree of noisiness, we shall simply regard noise as what it is - viz. unwanted sound.
