Confined space operations involve the necessary planning, procedures, and safety measures to ensure the safety of personnel working in these environments while completing tasks such as inspections, maintenance, or rescue operations.

What is confined space?

Confined space operations refer to activities conducted within confined spaces, which are typically enclosed or partially enclosed areas with limited entry and exit points and a restricted atmosphere. These spaces may pose risks such as poor ventilation, hazardous gases, limited visibility, or physical obstructions.

Benefits of confined space operations include the following:

  • Enhanced safety with humans removed from the equation
  • Increased operation efficiency and frequency
  • Cost saving by replacing traditional methods
  • Access to dangerous or off-limit to human areas

Confined space considerations

Confined space operations have a number of considerations that need to be taken into account before getting off the ground.

Regulatory compliance

Confined space operations require planning and are sometimes overlap with EVLOS operations, and therefor authorisations from CASA could be required to ensure safety and risks are considered.

Asset retrieval

If required, retrieving the drone that stopped working for whatever reason could be needed in line with regulations. Therefore, an asset retrieval plan should be in place.

Environmental variables

Confined space drone operations are often done in not frequently visited areas with little to no ventilation. This could mean dangerous gas levels could have built up overtime, making operations dangerous to undertake.

Training and competence

Pilots involved in confined space operations should undergo comprehensive training to understand the associated risks, safety procedures, and emergency protocols.

Risk assesment and management

A comprehensive risk assessment before each confined space operation to reduce the chance of damage or loss of a drone and environmental conditions.

Insurance and liability

Additional insurance might be required due to the higher risk working environment the drone could be subjected to.
