Hose pressure testing commonly involves the application of stored energy, or pressure, to various assemblies, components and parts found within industry standard machinery and equipment. The test is applied to determine the overall strength, functionality and integrity of an individual component. Those responsible for the safety of employees and the functionality of machinery should be fully aware of hose pressure testing and how it benefits the business for the long term. Here we will look into the required safety precautions necessary for pressure tests, which ensure the safety of test engineers and employees alike.
The actions necessary that comply with test regulations will vary on the component itself. Each component should be reviewed as follows:
- The overall size of the component during a pressure test.
- The specific test pressure that the component is designed for.
- The specifications of the pressure test being performed.
There are key factors that should always be looked into before performing any pressure testing. They are as follows:
- Assessing the possible risks.
- Writing a pre-planned safety system in the work place.
- Assuring the components being tested is kept segregated from other components during testing.
- Maintaining the required safety features during the test.
The amount of risks involved with using pressure in any form is incredibly high. When stored energy is applied to an assembly, (with a greater risk when subjected to stored energy for the first time), there is always a chance that an unintended release of pressure could occur, damaging both important machinery and employees who stand within the danger zone.
Releasing stored pressure suddenly can:
- Cause the component to suddenly rupture, which can lead to pieces being flung at high speeds.
- Cause a component to fail. If a hose is being tested, this can cause the hose to detach and whip violently.
- Cause the liquid, gas or solid to eject from the component and cause severe damage to machinery or employee.
