A legal requirement under the COSHH regulations is the testing and maintenance of all control measures used to reduce exposure to hazardous substances. ESL can design Local Exhaust Ventilation (LEV) systems for controlling airborne contaminants and can carry out the necessary regular testing of such systems. Measurements will include face velocity, static pressure, pressure differential across filters, air temperature, fan speed etc.

This includes indoor and stack monitoring. Indoor monitoring may be necessary to comply with the requirement of the COSHH regulations for monitoring of the exposure levels of personnel to hazardous substances including fumes, dusts and gases. Monitoring methods used are based on current HSE preferred techniques.

Environmental Protection Legislation (EPA 1990) requires emissions from stacks to atmosphere to be monitored. This includes monitoring of VOCs, gases and particulates (e.g. isokinetic sampling) from stacks. Other parameters such as duct and stack velocity are also included. An on-going programme can be arranged.

The overall amount of air entering and leaving a building is of fundamental importance in assessing the working environment. The traditional way of determining air movement is to measure the bulk of airflow through the area. ESL can carry out not only the airflow measurement but also modeling of airflow in a building. Such modeling enables areas of thermal comfort, dead zones, and draughty areas to be identified quickly so that appropriate improvements can be put in place.

The adverse publicity, absenteeism and reduced productivity associated with Sick Building Syndrome (SBS) has highlighted the need for improved air quality. To help ensure that air conditioning / handling systems provide, and continue to provide, a hygienic and quality indoor air supply, ESL can offer the following range of services:

• Surveys and risk assessments of air handling units.

• Ventilation and thermal environment surveys.

• Routine monitoring of indoor air quality.

• On-going monitoring programmes to meet specific client needs.

Control of noise and vibration which can affect the health of employees is within the scope of the general duties of employers under the Health and Safety at Work Act 1974. For exposure levels between 85 and 90 dB(A) noise assessments and control strategies are mandatory.

ESL can provide analytical chemistry services to NAMAS accreditation including GC and toxicological testing.
