Health and Safety Officers and Property Managers are faced with difficult issues every day. Awareness of industrial hygiene and indoor air quality issues have increased steadily over recent years.

Employers, whether in an industrial or office setting, are concerned about the risks associated with exposure to contaminants and the effects of worker health and safety on the bottom line.

What preventive and proactive approaches can be implemented to improve worker health and safety and ensure compliance with current regulations?

Our Approach

On-going issues require on-going solutions. Many of LEX's clients use our Industrial Hygiene specialists for long and medium-term contracts in order to ensure compliance with regulations.

Our expertise is invaluable for critical decision making. Furthermore, cost effective solutions to specific complaints are delivered by our professional staff in a rapid, concise, and consistent manner.

Our Solution

Armed with the mandate to solve Industrial Hygiene and Indoor Air Quality problems, our team conducts sampling in your workplace.

Samples, in the form of solids, liquids, or gases, are returned to LEX's industry recognized laboratory.

The samples are analyzed for targeted contaminants. Once the analysis is completed, the problem is diagnosed and remedial actions are recommended.

Results are communicated with concise, easy to understand, yet scientifically sound reports. Thorough training for the client company's staff is available where required.

Mould has, within the last few years, become a widespread concern for workers and building owners alike. During construction of new buildings as well as management of existing ones, mould can easily become an issue, growing behind walls and sending out spores, microbial volatile organic compounds (MVOC's) and mycotoxins.

Our Approach

LEX's experienced field staff will do in-depth visual inspections of the structure and building systems to find visible and hidden fungal growth. Where indicated, LEX can collect a wide variety of bulk, dust, and air samples to determine the extent of the problem. We will interpret the sample results and report back to you in a timely manner, because your needs are important to us.

Our Solution

By staying current and watching for new developments in this quickly changing field, LEX Scientific will provide you with the answers. Backed up by LEX's in-house AIHA EMPAT participating laboratory, we will guide you through the mould abatement process and taking the right steps to prevent mould regrowth.

Asbestos is still posing a challenge to property managers and maintenance people alike. Used in pipe and boiler insulation, ceiling tiles, floor tiles, fireproofing, as well as many other applications, asbestos can still be found in many buildings today.

The ability of airborne asbestos fibres to lodge in the lungs of workers and building occupants can cause serious health effects.

Recent client issues have included: out-of-date reports, asbestos in a facility constructed "asbestos free" and Ministry of Labour orders to clean up damaged asbestos.

Our Approach

LEX provides a full range of services from site assessments to all aspects of the abatement process including on-site air clearance.

Our NVLAP accredited asbestos laboratory allows us to offer excellent service with quality results you can trust.

Our asbestos management software programs, asbestos management plans and pre-renovation fibrescopic inspections of building cavities are some of the specialized services we can offer.

Our Solution

Our highly trained consultants are continuously striving to exceed the expectations of our clients. Working closely with our clients, we will provide practical solutions in a timely, cost effective manner.

Our NVLAP accredited asbestos laboratory offers fast turnaround time and accurate results based on accepted scientific methodologies.


Radon is a colourless, odourless naturally occurring inert radioactive gas derived from the decay of uranium found in soils or rocks. Radon gas may migrate and accumulate into building spaces, such as basement or crawlspace through pores or cracks in dirt concrete/foundation floors or walls. It can also seep into groundwater and be released by water agitation, such as turning on the tap.

Health Effects

Radon's presence in your home can pose a danger to your family's health. Radon is the leading cause of lung cancer among non-smokers. Although lung cancer can be treated, the survival rate is one of the lowest for those with cancer. Two studies, a North American study and a European study, show definitive evidence of an association between residential radon exposure and lung cancer. They confirm the radon health risks predicted by occupational studies of underground miners who breathed radon for a period of years. Early in the debate about radon-related risks, some researchers questioned whether occupational studies could be used to calculate risks from exposure to radon in the home environment. "These findings effectively end any doubts about the risks to people of having radon in their homes, said Tom Kelly, Director of EPA's Indoor Environments Division. "We know that radon is a carcinogen. This research confirms that breathing low levels of radon can lead to lung cancer."


The present guideline in Canada, established in June 2007, suggests an allowable exposure limit of 200 Bq/m3, down from the previous 800 Bq/m3 limit. Health Canada recommends that:

  • Remedial measures should be undertaken in a dwelling whenever the average annual radon concentration exceeds 200 Bq/m3 in the normal occupancy area.
  • The higher the radon concentration, the sooner remedial measures should be undertaken.
  • When remedial action is taken, the radon level should be reduced to a value as low as practicable.
  • The construction of new dwellings should employ techniques that will minimize radon entry and will facilitate post-construction radon removal, should this subsequently prove necessary.

The term, "dwelling" in the guideline also applies to public buildings with a high occupancy rate by members the public such as: schools, hospitals, long term care residences, and correctional facilities. So, the first step would be to test your facilities for radon and LEX Scientific would be pleased to be of assistance in testing your building(s) to guard against radon hazard.
