Man Entry Case Study 1

Sometimes there is no alternative than to manually enter a sewer to carry out a survey. Therefore it is important to have the correct training and ability to safely enter a confined space environment.
Our site managers are trained in the management of confined spaces to be able to plan, design RAMS and execute challenging man entry procedures. All our operatives are City & Guilds trained in “confined space entry (High Risk)” and “confined space rescue”. We use explosion proof (Ex) radios and torches and our operatives wear full PPE.
We have live entry and exit recording systems in place and these are documented. Our confined space RAMS and site specific risk assessments are also documented.
Our equipment includes gas detectors, BA and escape sets, man riding winch, fall arrest winch, tripods, nano lock above ground fall arrests and PID monitors. The safety critical confined space equipment is checked and documented prior to each use.
