Risk Survey

We consider health and safety highly important in manhole inspection. We are conscious of this and have therefore made a reputation of carrying out smooth manhole inspections in the Trelash area.

By using the right barrier system to keep it stable and the right tools to raise the cover, we can avert such injuries.

We cut off external influence by isolating the area. We possess a thorough understanding of the challenges that this work can pose, whether it's a physical or psychological hazard. We therefore ensure that all our workers maintain great health prior to and in the course of the manhole inspection process.
