Frequently Asked Questions
I want to have a company come to test the air in my home. Is this something that Airzone can do?
Unless an IAQ problem is due to an obvious source such as a recent renovation, new carpets, visible mould or water damage or sewer odours, investigations can be time consuming and therefore costly. A typical investigation can cost more than $1,500 for a residence including analysis expenses and may not yield an immediate resolution to the IAQ issue. Homeowners find this cost prohibitive.
Many problems can be diagnosed with a detailed questionnaire, and we often provide an initial consultation over the phone to determine if a problem can be easily diagnosed.
Information about IAQ issues can be found at the CMHC website, http://www.cmhc-schl.gc.ca/en/corp/faq/faq_005.cfm, Health Canada website, http://www.hc-sc.gc.ca/ewh-semt/air/index-eng.php, or the US EPA website, http://www.epa.gov/iaq/pubs/insidestory.html. Moreover, the CMHC Residential Indoor Air Quality (IAQ) Investigator Training Program lists of qualified practitioners independent IAQ investigations. CMHC?s: Tel: 1-800-668-2642.
I have concerns about the air quality in my workplace. What should I do?
First, talk to your manager or the designated health and safety officer. The problem may be resolved by increasing the fresh air supply, or doing minor adjustments to the HVAC systems such as re-balancing. If the problem appears more difficult to diagnose, we may be able to help.
I work in a managerial role, and there seems to be a problem with the air at my workplace of which the employees are complaining. What should I do to resolve this issue?
Try to pinpoint the problem by first speaking with your employees. They may be experiencing discomfort due to factors such as temperature, humidity or lighting, which can lead to the perception of indoor air quality issues. Carbon dioxide (CO2) or carbon monoxide (CO) concentrations above acceptable levels can influence a person?s perception of indoor air quality. Once the source of the complaint is found, the solution may be clear. However, if the problem is related to moulds, or chemicals used in production, maintenance, or cleaning, it may require further investigation and you may need expert help. Send us a note by email or contact us to discuss the issue.
Ever since the office was renovated, theres been a change in the air quality for the worse. Is there a connection? Why would this happen? What can we do about it?
Often new building materials off-gas and volatile chemicals from the materials evaporate into the air and cause odours. Increased ventilation is always a plus and dilutes the chemicals in the air of the affected building. However, if the odours cause employees to feel sick, we can perform an IAQ assessment to identify the offending indoor air contaminants and determine if their concentrations are in the acceptable range according to Health Canada and Ministry of Labour guidelines.
I'm being exposed to a hazardous substance in the air at work. What should I do?
Report this to your supervisor since workplace exposures to hazards need to be documented. Your company should investigate the issue, the source of the problem and possible solutions. This may require help from specialists in occupational health and safety. If no action is taken within a reasonable period after reporting the problem, then consult the Ontario Ministry of Labour.
We need to update our safety procedures at work, especially for personal protective equipment (PPE). Can your company help us with these?
Airzone can help you with updating workplace safety procedures and with conducting fit tests for face masks as part of the PPE.
We received a visit from the Ontario Ministry of Labour. They ordered a designated substance assessment based on the MSDS of the products we use. Can your company help us with this?
This is part of the routine occupational health and safety and industrial hygiene work that we undertake for clients. We can assist clients with demonstrating compliance.
There's an odour problem in my workplace that either comes and goes or is persistent. Can your company help me with this problem?
Frequently, transient odour events can be monitored with long-term passive sampling or summa canister methods to collect representative samples when the incident occurs. In the past, we have instructed clients on deploying these samplers and allowed them to sample when odours occur. If the odours persist or occur at the same time of day, our air quality specialists can perform a more comprehensive investigation.
