Frequently asked questions
What does the Frontline GUM manhole guardrail protect against?
It rings an open manhole or hatch with portable rail so attendants and passers-by working at surface level are protected from the opening while the entry team works below.
Does the GUM replace confined-space entry gear?
No — it is surface protection around the opening. You still need your tripod or davit, retrieval SRL, gas monitoring and a written entry/rescue plan.
Can the GUM be reused on different openings?
Yes. The rail sections are portable and set up quickly, so the same system can protect openings across the jobsite.
Is the GUM guardrail CSA certified?
It is a structural guardrail product, not CSA Z259 PPE — confirm its configuration and load rating against your province’s requirements for openings in work surfaces.
