How Not To Do It

CableSafe Confined Space Safety products significantly reduce accidents in confined spaces. According to OSHA, confined space work is one of the leading causes for occupational fatalities in the U.S. The entry barrier makes sure you will work in a safe environment.

We see that in some cases alternative solutions are chosen (see image below). Unofficial / improvised solutions are never as good and reliable as CableSafe Confined Space Safety products like the manhole barrier. We would always recommend the use of official Confined Space products


Safety is at the forefront of what we do. It is therefore important to understand why safety measures such as manhole barriers are necessary. Here are some questions and answers about our manhole barriers:

What is a Manhole?
Usually a manhole entry is used to conduct an inspection or for cleaning to name a few examples. These holes can be dangerous without a manhole barrier and can cause many accidents with serious consequences. A sturdy sign with a warning/restricted access sign is used as a manhole gate or entrance barrier to keep people without access out. 

Why use a manhole barrier?
A manhole in space where there is heavy construction and a lot of employees walking around is a health hazard that needs to be dealt with. Manhole barricades help to warn and keep people out of manholes which are too dangerous to let people go in unsupervised.

Why the Manhole Entry barrier?
Although our Manhole Entry Barrier has a lot in common with the man-way cross barrier, there are differences present that keep these two apart. As opposed to the cross barrier, our entry barrier is adjustable, meaning that it can be extended or shortened according to the size of the manhole.The entry barrier is also perfect to use in diverse settings; whether the hole is wood, rubber or metal, this barrier will be robust regardless of the hole and weather conditions.
We also offer the text in various languages so that our customers can make use of these worldwide.
