Before you enter into the blocked manhole Twickenham, you have to keep in mind the following safety measures. You need to have an emergency action plan and remember that no person should enter into the confined space such as the blocked manhole to get someone who is unconscious without leaving a person who is trained over the ground to help him. A person who enters in a confined space to offer the rescue has to have the right equipment and he has to be aware of the best rescue procedure. Be cautious when it comes to working around the manholes. You should not produce sparks, have open flames, or even smoke in the immediate vicinity when there is an open manhole. Before you remove the covers on the manhole, you have to know the atmosphere that is found within and you need to use aspirators. You should use the hooks and the picks in order to open the manhole covers. When you lift the manhole covers, you need to have heavy hatches on the legs. You should never lift using the back muscles. Lay the removed manhole with the heavy hatch covers flat at the ground many feet away from the opening.
When a manhole has been opened, then its opening should be guarded at once with a temporary barrier, a temporary cover or railing to avoid anyone falling inside accidentally. You should use any warning devices and barricades in order to direct the traffic near the manholes. You can follow the public service department to see the confined space entry program with the safety procedure before you decide to enter into a manhole. At least two people should be near the entrance of the manhole. A person has to enter in the manhole and another has to observe and alert the other person when there is an emergency under a blocked manhole Twickenham.
