Example: A car wash supervisor died when an air tank exploded in a car wash equipment room. The investigation showed that the pressure relief valves had been tested by the National Board Testing Laboratory and found it to be functioning properly. In an independent evaluation it was discovered that there were products of combustion in the air tank. They reported that this was most likely caused by the wrong viscosity of oil being used (not manufacturer recommended oil). Read the full article
Admittedly, this is a rare accident. What it should show us is the potential hazards that can be the result of cutting corners.
In an effort to take some precautions to ensure that this does not happen at your wash, be sure to have air tanks and compressors inspected and serviced on a regular basis. Please use original equipment manufacturer oil and maintain documentation of all repairs/servicing.
A few more tips:
- Air pressure should be drained regularly (weekly).
- Service should be done annually.
- Oil levels should be checked once a week. (If you notice it needs oil often it probably has a leak and should be checked/repaired.)
- Keep maintenance logs up to date.
