Aztech Services Australia Pty Ltd (Aztech) was requested by Alex Thompson, HAZMAT Manager of EHO Consulting Pty Ltd (EHO) to provide this Letter of Reference in relation to works conducted alongside Aztech, in particular Bush Fire Make Safes. Aztech has worked with EHO since establishing our Sydney Branch in January 2019; EHO is Aztech’s preferred hygiene consultant in Sydney. EHO has proved to be highly dependable, furthermore demonstrating experienced guidance and advice throughout onsite supervision and upper management. Recently, Aztech has conducted over 50 Make Safes to properties across NSW damaged due to current bush fires. Aztech has successfully worked alongside EHO to ensure properties are made safe, all suspect materials are sampled and reports are generated as a matter of urgency. Due to the nature of the emergency, at times EHO were only provided a few hours’ notice of departure for make safes in remote areas; EHO were constantly reliable and always had sufficient resources available to meet demands. The Bush Fire Makes Safes have proved to be tricky undertaking. EHO’s professionalism, guidance, reaction times and dependability have been a vital contribution to the successful delivery of the projects thus far.

During the past year EHO has become one of our preferred asbestos consultants in NSW. We continue to be impressed with the reliability and quality of work EHO produces. EHO has completed emergency make safes, asbestos and mould assessments and remediation strategies, including project management/supervision on programmed works for Advanced Buildings. EHO has demonstrated to be reliable, sufficiently resourced, and great with our customers and clients. EHO has provided Advanced Buildings with innovative remediation solutions, whilst ensuring that our clients' obligations to the environment and occupational health and safety are upheld. EHO has always had a quick response time to emergency make safe requests and deliver detailed and informative reporting on time. I would highly recommend EHO Consulting's services for any occupational hygiene works. Should you have any questions regarding this letter of reference, please do not hesitate to contact me.

EHO is UBS’s preferred hygiene consultant in NSW, assisting with the project management of programmed works, asbestos sampling and surveys, small scale removals, mould remediation strategies and make-safes.
