In terms of fire safety, FRP ducts have a superior rating due to their inherent flame retardancy. They do not support combustion and produce minimal smoke, ensuring safety in case of a fire emergency They do not support combustion and produce minimal smoke, ensuring safety in case of a fire emergency They do not support combustion and produce minimal smoke, ensuring safety in case of a fire emergency They do not support combustion and produce minimal smoke, ensuring safety in case of a fire emergencyfrp duct. This feature, along with their acoustic insulation capabilities, makes them a preferred choice for commercial and industrial applications.

It was not until the development of the hydraulic drifter in the 1950s that rock drilling truly entered the modern eradrifter for rock drill. This innovative tool used high-pressure hydraulic fluid to power a piston that rotated the drill bit, allowing for much greater penetration rates and precision. The hydraulic drifter quickly became the go-to tool for drilling holes in hard rock, paving the way for many of the major engineering projects of the time.
