OH&S and Industrial Hygiene

Indoor Air Quality (IAQ):

IAQ problems in buildings are often characterized by unusual odours or occupant health and comfort complaints, to name only a few. The potential causes can be difficult to find and rectify. Contaminants may be introduced into the building airstream from indoor or outdoor sources, or both, and may be transitory in nature.

LEA uses state of the art data-logging instrumentation, and sampling and analytical techniques to monitor building air quality and comfort factors over days or weeks (as opposed to spot sampling), in order to study conditions under a variety of environmental, operating and occupancy states. Usually, ventilation efficiency, temperature and relative humidity, exhaust gases, formaldehyde (from off-gassing building materials, adhesives, etc.), particulate, and volatile organic compounds (VOCs) are amongst the factors studied. Where building conditions suggest the possibility of mould contamination, fungal spores may also be counted and identified by species.

The assembled data are used to prepare a detailed report describing both the identified issues, proposed solutions and any recommended follow-up actions.

Worker Exposure Control & Monitoring:

Where there is risk of workers being exposed to hazardous materials or physical conditions, an Exposure Control Plan (ECP) is required to be in place for the work site. Steps in the process include a detailed risk assessment, development of the ECP itself as well as Safe Work Procedures, and monitoring during work to ensure the hazard controls and procedures in place are effective.

LEA has extensive experience in implementing ECPs for Asbestos, Lead, mould, bacterial and viral hazards, silica, and heat & cold stress, noise, and many other hazards.

LEA can also provide assistance with WHMIS (Workplace Hazardous Materials Information System) program implementation, training needs analysis, risk assessment and worker training.

Hygiene Laboratory and Field Services:

LEA offers full, in-house analytical services for aerosol fibres (such as for example during Asbestos abatement, bulk Asbestos materials, Lead based paint (LBP), pressure treated wood preservatives and Elemental analysis by X-ray Fluorescence (XRF), and surficial fungal spore and spores in air analysis.

We also offer mobile Asbestos & fungal spore laboratory services, and on site or in-situ XRF testing for LBP, Lead swabs, Lead in air (filter analysis), Arsenic, Copper and heavy metals.

In cases where mould contamination is suspected, we employ infra-red thermal and fibre-optic imaging, and in-wall spore sampling to identify and confirm suspect areas.

Staff & facilities in Nanaimo and Courtenay, same day sample turn-around, and CALA and AIHA quality assurance accreditation are three good reasons to have us meet your analytical needs.

Hazardous Materials:

Hazardous materials and related risk assessments are required by WorkSafe BC and most municipalities before demolition or renovation of buildings is undertaken, as well as for post-fire and -flood restoration. These investigations typically require an inventory of Asbestos containing materials (ACM), Lead based paint (LBP), PCB-containing electrical apparatus, ozone depleting substances (ODS), heavy metals such as Mercury, mould contamination and other bio-hazards, and building specific hazards.

LEA has extensive experience with these assessments, and regularly provides the required report(s) in a short turn-around time at competitive prices. This is made possible by our in-house analytical capabilities for bulk Asbestos materials, Lead based paint (LBP) screening by field portable X-ray Fluorescence (XRF), and fungal spore analysis.
