It is generally recommended that calibration is performed if it is suspected that the instrument has been subjected to any condition that could have an adverse effect on the unit such as; sensor poisons, high gas concentrations, mechanical shock, liquid spill, and temperatures, etc.

Most well-known manufactured gas detection equipment works within temperature ranges of -5°C and up to a maximum of +40°C

In recent times the UK has seen temperature ranges drastically increase and decrease. In February 2019 temperatures were recorded at lower than -12°C, and in 2022 we have seen temperatures reach 43.3°C in lincolnshire, with 34 sites exceeding 40°C.  These temperature ranges could mean gas detection equipment is void and no longer doing the job it should. 

To ensure the safe and accurate operation of Fixed Gas Detectors, they need to be periodically calibrated against reference test gases that are traceable to National Physical Laboratory standards. 

The recommended calibration period for most gas detectors is six months although the frequency may need to be increased where continual exposure to the target gases is experienced. 

Between calibrations, our fully trained engineers also check that the response of the detector is fit for purpose by using an appropriate specialist test gas. 

Detectors are ‘Optimum calibrated’ when manufactured, the performance and accuracy of the detectors can deteriorate with time, the rate of which depends on the type of sensor and the operating conditions e.g. dusty, corrosive or damp environments and temperature fluctuations can cause an accelerated decline in response and accuracy.

Due to this, it is vital to consider the manufactures recommendations for testing and calibration frequency.  It is recommended that the detectors are recalibrated and tested on an annual basis at least.

The Factories Act 1961 is an Act of the Parliament of the United Kingdom. At the time of its passage, the Act consolidated much legislation on workplace health, safety, and welfare in Great Britain. Though as of 2008 some of it remains in force, it has largely been superseded by the Health and Safety at Work, etc. Act 1974 and regulations made under it. However, the Act continues to have legal importance in cases of chronic workplace exposure to hazards such as gases. 

The Factories Act 1961 states a requirement for all gas detection systems to be systematically examined and recalibrated. Regular checking and calibration in compliance in accordance to BS EN 60079-29-2:2007.

BS EN 60079-29-2:2007 legislation also states that gas detection systems must be serviced every 6 months. 

Whilst the PUWER 1998 (Provision & Use of Work Equipment Regulation) states “safety equipment needs to be effective and maintained”.

viewmyair services will provide you with a dedicated account manager, whether you are a large corporate business, an independent school, or an NHS trust. viewmyair services takes the safety of gas detection very seriously. That's why our teams are trained to the highest level of gas detection safety compliance

Your dedicated account manager will allocate you one of our gas detection engineers who will conduct the following;

• Visual inspection to confirm that all cabling, fittings, and equipment is secure, undamaged, and adequately protected and that sensor housings are not obstructed or covered in any way.
• Sensor positioning checked for correct siting.
• Control Panel Isolator check.
• Power up and ensure no system faults are being reported.
• Full system function check
• Appropriate test gas to be applied to all detector heads, with diagnostics and results recorded.
• Confirm that the control unit alarm lamps and internal sounder operate satisfactorily when test gas is applied.
• Check for any remote indicators and sounders connected to the system respond correctly.
• Clean and remove any dust/ debris from sensor enclosures
• Function check to auxiliary equipment
• Test Gas Valve power output
• Ensure that the system is fully operational after servicing.
• Check that operational manual are readily available.
• Test date label attached to the equipment.
• A fully comprehensive and interactive servicing report issued to you within 48 hours of completed calibration/servicing
