Workplace Exposure Monitoring Training

by Environmental Monitoring http://www.em-monitors.co.uk

Environmental Monitoring are approached by dozens of companies every week who yearn to learn a bit more of what appears to them as the “black art” of monitoring.

In most cases this is for “workplace exposure monitoring”Often what happens is that the client is under pressure to obtain something, some device that will provide results but all done at the lowest possible price.

In many cases an internet search will reveal a plethora of devices that can offer a myriad of results aligned to dust, gas and a whole host of parameters all for less the £100. It appears to good to be true, sadly it often is.

Currently, the current recognised method of monitoring is using a filter paper and pump. It would follow the following regime

  • What are we monitoring? dust, aerosol, gas
  • What is the method of monitoring?

Once we have the correct method of monitoring we can define

  • The type of equipment to use i.e pump and filter head,
  • The flow rate and settings
  • The calibration method
  • The method of sampling
  • Working with a laboratory and obtaining results
  • The calculations
  • Report Writing

The additional part of the jigsaw that is required to complete the above, is training. In order that you apply your work place exposure monitoring methods correctly you will require training. Environmental Monitoring provides training to cover training for workplace dust exposure monitoring

Indicative monitoring. Real time methods provide a useful indication of dust concentration within the workplace. However it is important to note the following :

  • There is no current indoor air quality monitoring standard
  • There is no current real time indoor air quality monitoring standard
  • There is no real time work place exposore monitoring for dust

However that said, real time monitoring provide invaluable information especially where aerosols are concerned

The very latest systems can provide real time measurement of dust and a number of gases. Handheld variants provide accurate measurement of pm2.5, pm10 and a single gas

The most important thing to follow are monitoring standards for real time monitoring

Real Time Workplace Dust & Gas Monitoring

Environmental Monitoring(www.em-monitors.co.uk) supply a range of unique real time monitors designed for both workplace monitoring and indoor air quality.

The unique features: real time remote monitoring of dust and gas to any computer in the world. Alarm on critical levels via phone or visual indicator . The beauty of the product is that is so simple to set up and use : typically 20 mins

The number one question presented to Environmental Monitoring is can I monitor dust and gas, specifically NO2 in my work environment continuously and get some kind of visual warning when the quality of the air becomes poor. Well yes you can. There are now two options of monitoring device. The first, the airmite, continually monitors dust as fine particulate such as PM1, PM2.5 and PM10 together with a choice of 4 gas from NO2, NO, O3, SO2, CO2, CO as well as VOC’s by photo ionisation detector (pid). Data logging is real time and user definable from 1 second upwards


  • What makes it outstanding: The box is particularly well designed, not only will it with stand radio frequency interference (rfi) it will also with stand temp and relative humidity fluctuations in the harshest environments. The results it gives are both accurate and reliable

For cost effective, reliable monitoring for dust in you work place, office , building school, university ,hospital. Contact Environmental Monitoring. We can not only sell this product we also hire it. Hire Rates start from £450/week , Environmental Monitoring provide advice on sensor choice and locating the device. we provide a set up and reporting service

New Device Launch. From February a new handheld single gas and dust monitoring device is available. Contact adrian@em-monitors.co.uk for info


Pid Hire & Sales

Environmental Monitoring are a specialist supplier of pid’s ( photo ionisation detectors) for hire and sale. What makes us different? When you hire from us, immediately your getting an expert advising you. We will go through your monitoring application and determine whether if the instrument if suitable for your application. Not all vapours can be monitored and measured using a pid. it may require an fid, or infra red monitor, it may even by ftir or gc monitoring that is required. For speciation the simplest method is using absorption tubes followed by analysis.

For hire prices contact http://www.em-monitors.co.uk. sales@em-monitors.co.uk. our hire rates start at £75 for a personal worn pid, Hand helds start at £100

Recently a pharmaceutical client needed to measure a specific solvent in a vent stream. However we were able to determine that two factors made it not useable. 1st the the ionisation potential was such that it would not be visible and secondly there was moisture in the stream. This would cause the lamp not to work

In order for a gas to be “visible” the ionisation potential(ip) of the gas being monitored must be less than that of the lamp. A standard lamp has a IP of 10.6 eV so that a solvent such as IPA with an IP of 10.1 will be “visible” and can therefore by monitored. Whereas a substance such as carbon tetrachloride has an ip of 11.47. it will not be “visible” to a 10.6 eV lamp but can been “visible” to a 11.7 eV lamp

Air Quality Nuisance Monitoring

by Environmental Monitoring http://www.em-monitors.co.uk

Ref BS 5228 1-2009 The control of noise and vibration of construction sites and open sites came into practice on the 21st Feb 2014 and 3rd June 2014 respectively

Under section 71 of the Control of Pollution Act 1974, the Secretary of State may give guidance on appropriate methods for minimising noise by approving codes of practice. The Secretary of State is required to approve a code for the carrying out of works to which section 60 of the Act applies. Section 60 applies to construction works, which include building and road works, demolition, dredging and other works of engineering construction.

Section 60 and 61 Notices. These are used by the authority to impose specific conditions on the construction or demolition site. They may imposes certain conditions on the site such as : Working hours, Noise limits and Working practices

How can monitoring be undertaken reasonably and reliably. A real time monitoring device is usually placed at the boundary that requires monitoring or close to a point where nuisance may occur. The monitors monitor noise, vibration and dust on a real time basis. They have the ability to sent text alerts should a breach occur and can configured to provide a fully functioning report

Em-monitors is able to provide boundary monitoring equipment to your site either for hire or for sale. We can provide it direct to your site, provide connection help and supply training on how to configure your report. We can even provide monthly reports direct to you.

The most important part about any form of monitoring are:

Why we are monitoring? -Legislation

How we are monitoring: Method of monitoring ( protocol and guidance method)

What we are monitoring and accuracy. Equipment and validation of equipment

Air Quality/IAQ Monitoring

By Adrian Thiedeman of Environmental Monitoring. http://www.em-monitors.co.uk

There is an increasing requirement to monitor the air for dust and gas in the streets where we live, work and play. There is also now an increasing movement to be able to monitor dust and gas within the workplace and home.

Environmental Monitoring has teamed up with an organisation that has spent many many years designing a reliable and stable monitor.

The monitor is able to detect fine respirable particulate & ambient gas levels to ppb concentrations.Together with GPS & remote datalogging the unit is able to detect and record the following :

PM1, PM2.5 and Pm10 simultaneously on real time basis by remote data logging. whilst addition to this it can monitor any 4 gases from a selection of (NO,NO2, O3, SO2,CO and H2S).There is also an option for CO2 monitoring and the unit can be configured to monitor VOC’s at the expense of one of the gases. The rate at which this is logged is used definable

The monitor offers a number of solutions to the user. It provides real time data that is remotely accessible,via a 4G or ethernet connection. It also has on board logging facility. Power: The unit is directly configurable f0r 90 to 230v AC or 7-24DC with an option to be solar powered

Stable : both electronically and environmentally. This means the “electronic noise” that could affect the low level operation of the unit has been reduced to a minimum. The case has been designed to ensure it allows perfect 4G/ethernet communications and a robust capability to withstand harsh environments. The unit is lightweight and can be pole or wall mounted

Set up time: typically 20mins

What is required?

Too often time is spent with expensive certification systems. Whilst this offers a certain course of validation, It is often costly, prevents innovation and competition but moreover it can nurture poor science. It is therefore important that monitoring is method related, not just instrument specific

So what we are seeking to develop is a good set of working practices. A standard method of ambient air monitoring for low cost multiparameter real time monitors
