Environment

Protecting the environment and the communities around us

We work through consultation and engagement at village level — through our own representation, or alongside the client's — so that people living near a site know what is happening on it before work starts.

Zero harm is our operating standard.

Health & Safety

Supervisors set the standard on site

Project management and supervisory staff at every level are expected to be safety role models, building a strong safety culture through training, education and coaching rather than paperwork alone.

Led from the front, on every shift.

How we hold ourselves to it

Ten practices, checked on every project.

Standards and systems

What we work to

  • Complying with all applicable EHS laws and regulations in PNG, and actively following organisations such as WHS, NEBOSH and IOGP
  • Implementing and maintaining effective EHS management systems
  • Integrating our safety management plans and procedures with those of the client on every project

People and training

Who carries it

  • Ensuring all employees are trained on EHS procedures and practices
  • Verifying competency training programs are in place for our staff
  • Clearly communicating that safety is everyone's responsibility

Sites and operations

How it holds up in the field

  • Conducting regular EHS inspections and audits
  • Performing risk assessments in all operations and at all sites
