We've just had our gas burner serviced, and Premiere Servicing has classified it as 'At Risk/imminently dangerous' Can we still use it?

Following the proper protocols outlined in the Gas Industry Unsafe Situations Procedure, we advise against using the gas appliance. However, we understand that shutting down production can have significant consequences. In extreme circumstances, if the gas appliance is to remain in use, a risk assessment must be conducted by the responsible person.
