Health & Safety

Providing a safe and healthy work environment for all employees and sub-contractors is one of our primary goals.

Diona's Safety Management System is certified to AS/NZS 4801 and is built around continual improvement of our safety policies, processes and procedures. It includes training and induction for our employees and sub-contractors, with regular internal and independent external audits and reviews.

The OH&S Manager is responsible for communicating our safety policy and procedures to all staff, and through education and training, ensuring everyone is using current best practices.

Our staff are provided with compulsory internal training aimed at:

•    Ensuring workers and the general public are properly protected
•    Creating a proactive culture around OH & S, and
•    Encouraging innovation and learning.

Diona's health and safety procedures ensure its AS/NZS 4801 certification

By their very nature, our projects can have a substantial impact on the environment. So we take our environmental responsibilities very seriously.

Diona has a proven Environmental Management System to ensure all our work practices minimise, as much as possible, any negative effects on the environment. The system takes an integrated approach, ensuring we have multiple methods and tools at our disposal.

Diona's Environmental Management System is certified to AS/NZS 14001. Measuring, analysing, reviewing and monitoring our environmental management processes enables continuous improvement. Everything from erosion and sedimentation control methods to habitat protection practices are monitored, reviewed and adapted to meet site specific parameters, ensuring we always deliver the best possible solution.

Our Environmental Managers are responsible for ensuring all staff up to date on our environmental protection, waste minimisation, water conservation, and greenhouse gas reduction policies, and are competent to put them into practice.

Training and specialised site inductions ensure staff stay up to date with the latest environmental management techniques. Our policy is that all staff should be able to identify and manage environmental issues, and be vigilant in preventing damaging incidents.

Diona has an outstanding record in environmental management, however as new projects create new challenges, we are constantly developing new techniques and approaches.
