ARCO PROFESSIONAL SAFETY SERVICES SUPPORTS PIONEERING EXPEDITION OF MULU CAVE
Bartek Biela, an Arco Professional Safety Services Training Instructor, embarked on an expedition to Gunung Mulu National Park to support cave work efforts which could potentially lead to future confirmation of its status as the largest cave system in the world by volume.
3D laser scanning was used to measure the volume of sections of the Clearwater Cave system to identify new passages and areas. The discovery was found by revisiting old unfinished leads in the far reaches of the system which unveiled a vast connection, almost a kilometre long, leading to a chamber previously believed to be a dead end in earlier expeditions.
This discovery resolves one more of the many mysteries that characterise the intricate Mulu cave system. Today, larger passages are harder to find but the systematic approach employed to surveying of the smaller openings allowed the cavers to add hundreds of meters of new data to the master survey.

The three-week expedition, which comprised of 22 dedicated cavers and scientists to survey the caves, undertake scientific research and exploration, has also led to significant findings on the deterioration of fabrics.
Agents that are present in the Mulu caves environment have been found to cause significant degradation of man-made fabrics. These corrosive substances are being tested by UK and American cave scientists to establish the causes of significant degradation of glued seams, stitching and other man-made polymers.
Bartek Biela, Training Instructor at Arco Professional Safety Services, commented: “I am immensely grateful to have received the invite call to be part of this amazing opportunity, that would give me a chance to meet and cave with the original explorers of the area, an opportunity that one does not refuse.
“This expedition has delivered promising insight into the cave system and important, possibly even groundbreaking scientific research, not to mention the beauty of the underground landscape that I have had a chance to photograph.”
Richard Walters, the Expedition Surveyor, said: “Acknowledging the challenging conditions of Mulu, renowned for its punishing environmental factors—extreme heat, humidity, mud, and frequent rainfall—these explorers faced the rigorous task of navigating caves that often require multiple days underground. Despite these barriers, the cavers emerged with compelling results that suggest the Clearwater Cave system may be the largest by volume in the world.”
As one of the expedition sponsors, Arco Professional Safety Services equipped the expedition team with eleven kit bags which proved to be extremely robust and durable in the tough environment of the Mulu caves.
