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.

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

For environments with at-risk populations, it is important to do preventive inspections of the air quality and the indoor environment.

Our team of experts can help you:

  • Establish an annual plan for preventive checks on your institution’s indoor air quality
  • Check the air for comfort (temperature, humidity, ventilation rate or airflow problems) and health (mould, bacteria) aspects

Clean room checks

QUALITY ASSURANCE AND REGULAR EVALUATIONS

There are a wide variety of actions our experts can take to help ensure the quality of your clean rooms and white rooms.

  • Measuring various microbiology, chemical and physical contaminants
  • Comparing production standards (ISO 14644-1, USP 797)
  • Responding to water damage or work that can release dust or micro-organisms into the air
  • Supporting the client with regular assessments and identifying ways to improve the air quality and the microbiological cleanliness of surfaces
  • Checking high-risk environments (pharmaceutical, research centres, fibre optics)

Inspecting ductwork for contaminants

CHECKING WHETHER VENTILATION DUCTS ARE CLEAN, EITHER BEFORE OR AFTER A CLEANING

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

Our experienced staff can help you determine the source of odors and the origin of occupant symptoms, assess the potential impact on occupants and advise on how to correct the situation. We are also present during and after the work to ensure that the problem is properly solved.

Our experts can conduct analyses on different kinds of odours:

  • Mould odour: smells damp, earthy, like a cellar, etc.
  • Chemical odour: off-gas, formaldehyde (new smell), smoke, cigarette smell, sewer smell, dead animal smell, etc.

Indoor pools: mould and chlorine odour

INDOOR POOLS, HOT TUBS AND WATER PLAYGROUND CAN AFFECT YOUR AIR QUALITY

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

Moulds and biological contaminants

Mould investigation and sampling

CAREFUL INSPECTION AND ADAPTED MICROBIOGICAL ANALYZES

In accordance with the BNQ 3009-600 standard, our professionals take into account your objectives and the history of your commercial, industrial, or institutional building to determine the tests and parameters of the air quality to be analyzed.

Material humidity, thermography, physical, or chemical parameters, sampling of viable moulds, and total fungal spores: all these measures help us to establish a good diagnosis, and thus, provide you with a detailed report of the situation.

Our recommendations help you put in place the best solutions to improve the indoor air quality of your building.

Management of decontamination work

ELIMINATION OF CONTAMINANTS AND RHABILITATION OF YOUR BUILDING

In certain situations where the fungal contamination is very extensive, the moulds are found in a risk environment (hospital, CHSLD, school, etc.), or a destructive fungus such as the weeping rot (Serpula Lacrymans) is identified, monitoring work by a mould expert is required.

Our certified microbiologists support you in all stages of your decontamination work, from the decontamination protocol adapted to your building to post-work tests, including worker training and site supervision.

Certification of decontamination

CHECKING AIR QUALITY AND INDOOR ENVIRONMENT COMPLIANCE

In a disaster, poor diagnosis and unsuitable decontamination techniques for certain situations can leave contaminants in the interior environment of a building.

Our certificates of conformity make it possible to certify that the work has effectively eliminated the identified sources of contamination.

Visual inspection, material moisture measurements, surface sampling and indoor air quality testing are all steps that can provide the level of confidence desired by the occupants of your building.
