Boral strive to lead the way through a comprehensive dust management framework informed by our ongoing work with specialists and regulators to help ensure we are using modern management practices and dust control technologies to keep our people safe and healthy while at work.

 Like many in our industry and related industries, monitoring of respirable dust (RD) and respirable crystalline silica (RCS) is an established practice in place for many years.

At Boral, we undertake static dust monitoring, personal exposure monitoring as well as regular environmental (boundary) monitoring at relevant sites. Static dust monitoring and personal exposure monitoring helps us to better understand where potential risks to our people exist and if additional measures are required.

Health surveillance includes respiratory function tests and chest x-rays by a specialist radiologist accredited in occupational lung health. Under current regulations, health surveillance must be conducted at least every five years.

We continue to monitor and review our dust management approach and work collaboratively with regulators and government to make sure our controls meet and, where possible, exceed required standards to safeguard the health and safety of our people.

• fixed speed limit for all vehicles
