Working together through COVID-19

4-Way Inspection Services wants to notify our customers and all businesses that we remain open during this unprecedented time regarding COVID-19.

4-Way is committed to the health and safety of all employees, our customers, and the general public. In response to this, we have implemented a COVID-19 preparedness plan. For more information on our COVID-19 preparedness plan, please don’t hesitate to contact us directly.

We kindly request that our customers inform management and/or our technicians of any possible risks at your specific facility so that extra precautions can be taken as found necessary.

We also request that our customers notify us immediately if any employee or personnel on site has knowingly been exposed to COVID-19 within the last 14 days so that we can take all necessary steps to help stop the spread.

We thank you very much for your co-operation as we all work through this situation together and we wish everyone good health during these challenging times.

Parkades

Enclosed Parking Garage

Parkades can become hazardous areas when exhaust fumes collect and are not properly ventilated. To provide fresh air and remove contaminated air out of these parking garages, fans are typically used. It is neither practical nor economical to run the fans continuously, as wear shortens the life of motors and other associated equipment. More frequent maintenance services are then required and the energy consumption is not only expensive, but not environmentally friendly either.

Carbon monoxide is the most abundant of the exhaust fumes, but there is also the potential for nitrogen dioxide from diesel powered engines and in more modern facilities, hydrogen buildup from electric car charging stations. Carbon monoxide can be very lethal as it has no colour, odour or taste and may not be detected without the use of a gas detection system.

Exposure limits for Carbon Monoxide has an 8 hour occupational safety limit of 25 PPM. The effects of carbon monoxide are dependant on the concentration levels as seen below:

  • Less than 50 PPM = Mild headache
  • 50 – 200 PPM = Severe headache
  • 200 – 400 PPM = Weakness, dizziness, nausea, fainting
  • 400 – 1200 PPM = Increased, irregular heartbeat
  • 1200 – 2000 PPM = Loss of consciousness, coma, death
  • More than 2000 PPM = Death can occur in minutes

Gases Detected:

  • Carbon Monoxide
  • Nitrogen Dioxide
  • Propane
