When Is it Time to Replace Compressed Air Hoses
Compressed air hoses are powerful tools for workers in a variety of industries. While their power can speed up the pace of work, they can be extremely dangerous if used past their prime. A few key signs indicate when it is time to replace a compressed air hose.
Kinking
If a compressed air hose is permanently kinked, it is time to replace the hose. A backup of compressed air at the kinked area could lead to an explosion, which could be deadly.
Fraying or Cracking
The fraying of the protective fabric surrounding a compressed air hose -- or the cracking of the rubber if no fabric is present -- is a sign that the compressed air hose needs to be replaced. The rapid escape of compressed air from a hole in the hose can cause serious injury to workers and bystanders.
Bending
If a compressed air hose is bent, it needs to be replaced as soon as possible. Bending of a compressed air hose can drastically alter the air flow and potentially create an accident leading to serious injury.
Pressure Ratings
Each compressed air hose is rated to withstand a maximum pounds per square inch in air pressure. If a compressed air hose is not rated to withstand the compressor it is fitted to, it is time to replace the hose.
Maintenance
Compressed air hoses should be cleaned regularly using soapy water, not kerosene or other flammable material. After cleaning, make sure the compressed air hose is completely purged. While doing maintenance work on the compressed air hose, make sure the compressor or other equipment is attached to is turned off.
