A thorough risk assessment of the process has been carried out, led by gas testing specialist company, Kiwa. This risk assessment is based on:-
- The routine risk assessments that are done for regular gas safety checks in homes and buildings carried out every day, and two additional aspects, specific to HyDeploy;
- The connection and operation of bottled ‘test gases’ in homes and buildings.
- Undertaking the standard tests on the different gas composition.
Kiwa has safely undertaken over 1500 gas bottle tests in homes in Scotland for a previous project (Oban, SGN). They have also tested hydrogen blends on a range of appliances in their laboratory as part of HyDeploy. Based on this experience, they have undertaken the necessary risk assessments for the HyDeploy safety checks, which have been reviewed by Health and Safety Laboratory as well as Keele University.
The following risks are associated with the gas appliance safety checks:-
- Fire/explosion risks of working with gases.
- Carbon monoxide exposure during testing.
- Vehicular accidents.
- On-site working – e.g. slips, trips and falls.
- Damage to house/building gas appliances.
Appropriate mitigation measures have been put in place to manage these risks:-
- All gas testing work will be carried out by suitably qualified gas professionals.
- Appropriate training for all gas engineers ahead of the safety checks.
- The vehicle with the gas bottles on it to be clearly marked and parked safely off road.
- Step-overs and warning signs to be used around gas pipes.
- The use of appropriate gas detection equipment by gas professionals.
- Documents that clearly set out the agreed process.
The safety checking of appliances will be undertaken by qualified gas fitters with method statements and risk assessments developed by experts, and reviewed by Keele University and the Health and Safety Laboratory (HSL).
There is the risk that during the check one of your gas appliances may be found to be unsafe and be disconnected.
If any safety issues are identified then the team will switch off your gas supply and will rectify the problem or replace the appliances free of charge to ensure they meet the required standards.
Switching off the gas supply will cause some inconvenience, but it will protect your safety. The team will then ensure that you have temporary heating and cooking facilities while they work to solve the problem or install a new appliance.
Bear in mind that if these tests had not been carried out, and your device continued with a fault, you would be at risk. The tests will uncover potential risks and deliver a safer solution for you and your family.
