Dust, fumes, chemicals, noise - or even a sick building? If so, we can help you to comply with the law, keep your workers healthy and ensure that your organisation stays effective and efficient.
Almost all workplaces have health risks that must be eliminated, reduced or managed properly. The consequences of failing to do this can be extremely serious for the workers, management and shareholders.
Brian Milligan Associates UK are Environmental and Occupational Hygiene Consultants who will:- Identify hazards
- Assess the risks
- Advise on suitable control measures
- Check operation of current controls
Risk assessment involves:- Observation of the task by an experienced professional who has a wide knowledge of comparable workplaces in the UK
- Measurement of worker exposure to a chemical, physical or biological agent, by personal monitoring
- Measurement of conditions in specific areas of the workplace by area monitoring
- Evaluation of results against appropriate legal & scientific standards
Clients
The service is mainly aimed at small to medium-sized industries in all sectors - including engineering, plastics, pigments, chemicals, woodworking, food production, ceramics, textiles, transport & distribution.
Enquiries are welcomed from all types of businesses throughout the UK, although we are particularly well located to service clients within Greater Manchester and the North West of England.
Services
COSHH Assessment & Measurement of exposure to airborne substances by air sampling.
Examination and Testing of Local Exhaust Ventilation Systems.
Noise Monitoring - Assessment of Noise Exposure and Environmental Noise Measurement.
AIR SAMPLINGThere are many different types of chemical pollutants in the air. Their various physical states and chemical natures require different approaches to sampling.
Dusts and aerosols
- Collection on a filter followed by:
- weighing
- chemical analysis
- Direct reading instrument
Examples
Cement dust, welding fume, flour, hardwood, dyes & pigments, Soldering fume, oil mist, rubber process dust and fume.
Gases and vapours
- Collection on a solid adsorbent (e.g. charcoal)
- Collection on a chemically treated adsorbent
- Absorption in a liquid.
- Direct reading instruments
- Colour indicator tubes
Examples
Acid gases, hydrocarbons, solvents, ammonia, formaldehyde, carbon monoxide, hydrogen sulphide, chlorine.
Sample Analysis
Techniques most commonly used include:
- Gas chromatography
- High pressure liquid chromatography
- Ion chromatography
- UV/Vis spectrophotometry
- Atomic absorption/emission spectrophotometry
Exposure Guidelines
- Workplace Exposure Limits - Guidance Note EH40 - HSE
- Summary Criteria for Occupational Exposure Limits - Guidance Note EH64 - HSE
- Threshold Limit Values - published in the US by AGIH
- Research reports in the scientific press
- Textbooks on toxicology and industrial hygiene
VENTILATION TESTINGIf you have local exhaust ventilation (LEV) systems, be they spray booths, welding hoods, exhaust slots on degreasing-baths or larger multi-point systems, the law says they must be thoroughly examined and tested at least every 14 months.
Typical Test Parameters
- Visual inspection for damage or corrosion
- Pressure drop across fan
- Pressure drop across bag filters or other arrestment plant
- Pressure behind exhaust hoods
- Air flow rate through main system and branch ducts
- Air flow rate at booth face, or in front of exhaust hood
- Visualisation of air flow characteristics at contamination source or containment interface
Information provided by the examination & test
- Is the system likely to provide adequate control & containment?
- Does the system meet minimum standards of effective design and performance?
- Has there been any change in performance since the previous test?
- What action is necessary to achieve satisfactory performance?
- What maintenance/repairs will be needed to prevent forseeable loss of efficiency?
- Records must be kept 5 years
- HSE inspectors will always want to see them
- An essential element in defending compensation litigation
