When testing and tagging office appliances, I often see computers with a safety issue that has gone undetected for quite a while.
Here is a typical example;
You will notice the cooling intake vents have become very clogged with dust causing a significant restriction of the amount of air that can be drawn in.
It is a mandatory requirement of the physical and visual inspection of appliances to “Check ventilation inlets and exhausts are unobstructed“.
There are two main problems obstructed vents can create;
The fix for something like this example is quick and easy however prevention is always better than cure.
When we find computers like this we recommend the owner request their cleaner to incorporate checking and cleaning the vents on computers at regular intervals into their cleaning program. In most offices, once a year is usually enough but this can vary according to the actual environment.
I have also seen similar situations of blocked vents on a number of other types of appliances, such as “under bench” hot water systems and stationary appliances in workshops. The intake and exhaust vents are designed for a purpose, so ensure they are are unobstructed.
PS If you have recently had your computers or other appliances tested and tagged and notice the vents are blocked it is a big sign your test and tag technician has not fully undertaken the inspection process they are required to perform or they have overlooked the defect.
