With the temperature dropping, typically the dock doors are closed more hours of the day, which for many companies means less air circulation. This can lead to problems that could be ignored during the warmer times of the year, but not this time of the year.
When the dock doors are opened all day it naturally turns the air in the building and minimizes exhaust build up problems, but with the doors closed and reduced air circulation, excessive exhaust fumes can become a real problem.
The most commonly noticed problem is the Exhaust Fumes from the Propane (LP) Powered forklifts. While LP is much cleaner than gasoline, LP still burns oxygen and emits Carbon Monoxide (CO). There also have been several improvements in Emissions Controls, and these improvements have drastically reduced CO Emissions, but have not eliminated them.
Running propane powered equipment uses the available Oxygen and emits Carbon Monoxide. As we all know, CO can cause serious health problems or death.
Here are some of the problems of Extended Carbon Monoxide Exposure at different ambient CO Levels:
Here are some suggestions to help reduce the Carbon Monoxide emissions from your equipment:
In summary, measure both the ambient CO levels as well as the exhaust CO levels. If your heating & air conditioning system does not bring in enough outside air, exhaust emissions will be a problem even if the equipment is working perfectly. So make sure your equipment is running properly and make sure your HVAC System is supplying enough outside air.
