We will always work to your risk assessments, you would need to tell us what you require and we can then advise on the most suitable products to make that entry.
Of course you can, but please try to give us as much notice as possible and ensure that you have any relevant paperwork and purchase order numbers
We are open Monday – Friday, 8am to 17:30.
Taking into consideration the ATEX directive, manufacturer recommendations and your own company risk assessments, it is recommended that you bump test your monitor before every use, it is true that the law is not clear and doesn’t use the all-important word “MUST” and the regulation only surrounds flammable gases, not toxic, but you can guarantee that the authorities would want to see evidence of such testing should the worst happen!
A bump test is the only way to test that the whole gas detector unit is working properly. It checks that the sensors respond to the target gas, it also verifies that the display reacts and it confirms that all the alarms are activated and the detector goes alarm properly.
The principle behind bump testing remains the same across all manufacturers, with a target gas applied to the monitor for usually around 30-40 seconds with a flow rate of around 0.5lpm, this exposes the sensors to the target gas and the monitor (depending on manufacturer) will show gas readings and alarms should respond accordingly. You would normally expect to see readings within 10% of the target gas applied.
No. Whilst a monitor can initially pass the start-up process and indicate that the monitor is functional, what this doesn’t tell you is if gas can actually reach the sensor, as the sensor membranes can become clogged with muck, dust and particles that are not visible to the human eye and thus not allowing the gas molecules to reach the sensor and react in a timely fashion.
