REGULAR PREVENTIVE CHECKS OF INDOOR AIR FOR EMPLOYEE COMFORT, HEALTH, SAFETY AND PRODUCTIVITY

According to Boma Best and WELL certifications, it is recommended to periodically check the air quality of the different work areas, as they are not all equal. Some rooms can become unproductive following a bad calibration of the ventilation system.

To ensure the comfort and safety of your employees, our experts can assist you in the process of testing the air quality of your work environment in addition to analyzing various contaminants.

  • Mold
  • Preventive check
  • Clean room checks
  • Inspecting ductwork
  • Suspicious smells and symptoms reported by occupants
  • Indoor pools

Fungal contamination is one of the main air quality problems that can affect the health of building occupants. Investigation for the presence of mould in the air or in materials is carried out with careful inspection and specialized sampling techniques.

In accordance with the BNQ 3009-600 standard, our professionals take into account your objectives and the history of your building in order to determine the tests and air quality parameters to be investigated. All these measurements and analysis help us to establish a good diagnosis and thus, provide you with a detailed report of the situation.

In addition to assisting you in the rehabilitation of your building, our professionals are present in all stages of the decontamination work. Following the decontamination work, we can repeat air quality checks to validate the compliance of the indoor environment. Our experts can also provide a second opinion for any legal expertise related to air quality, mould and any other contaminant.

We verify whether your ducts are clean (dust, biological contaminants, etc.) through observation and samples taken from surfaces. We then establish whether your ventilation ducts need to be cleaned and prioritize which ducts and systems should be targeted first. Our impartial analysis gives you the straight facts.

  • Verification and post-cleaning certification
  • Testing and analysis in accordance with the NADCA standard
  • Sampling cassettes or weighing cassettes in the lab

Suspicious stains, earthy smells and chlorine odour can all cause people to experience discomfort or exhibit symptoms. We can help you deal with such issues by running tests to:

  • Assess the concentration of trichloramine, which is responsible for chlorine pool smell
  • Measure the relative humidity and moisture content in materials
  • Measure the concentrations of mould in the air and on surfaces
