About dss+

At dss+, you don’t just deliver projects - you help save lives, improve performance, and build a more sustainable future.

We are a purpose-led global consultancy partnering with organisations in high-risk and asset-intensive industries to solve complex operational challenges across safety, operational excellence, and sustainability.

With a heritage rooted in DuPont’s industrial operations, we combine deep expertise, practical problem-solving, and digital innovation to deliver measurable and lasting impact for our clients.

Why This Role

As a freelance Subject Matter Expert (SME), you will bring deep expertise in underground mine ventilation, fire prevention, and emergency response to support a major mining expansion project in Brazil.

Working alongside dss+ and client stakeholders, you will review operational procedures, identify operational and safety risks, challenge existing practices where appropriate, and provide practical recommendations aligned with industry leading practices.

Why This Industry

As underground mining operations become more complex and technically demanding, effective Ground Control is critical to protecting people, infrastructure, and operational continuity.

dss+ supports mining organizations in strengthening operational risk management by ensuring that technical requirements, Critical Controls, and engineering standards are translated into practical procedures that can be applied consistently in the field.

Your Impact at dss+

You will provide specialist expertise for the critical review, development, and improvement of operational procedures associated with underground mine ventilation, atmospheric hazards, fire prevention and response, evacuation, and emergency preparedness.

You will help ensure that ventilation requirements, operational conditions, emergency scenarios, and Critical Controls are translated into practical procedures that can be understood and consistently applied by supervisors, operators, contractors, maintenance teams, and operational leadership.

Key Accountabilities

• Review and evaluate underground ventilation procedures, standards, and management systems.


• Assess procedures covering primary, secondary, and auxiliary ventilation systems.


• Review ventilation surveys, monitoring practices, and atmospheric testing requirements.


• Evaluate post-blast ventilation and underground re-entry procedures.


• Assess operational responses to ventilation failures, alarms, and abnormal atmospheric conditions.


• Review underground fire prevention, detection, and emergency response procedures.


• Evaluate smoke propagation response strategies and ventilation management during emergencies.


• Assess emergency communications, evacuation procedures, refuge chambers, and escape route management.


• Support the development and validation of emergency preparedness plans and response procedures.


• Identify gaps between engineering requirements and operational execution.


• Facilitate workshops involving engineering, operations, maintenance, emergency response, safety, and contractor teams.


• Provide recommendations to strengthen operational and safety risk controls.
