In our travels in the waste management industry and in particular in our visits to landfills and we have found that despite the fact that in the UK there are health and safety regulations require (under criminal law) that for all cases confined space access to responsibility individuals must have completed a risk assessment and shall only work to carefully judged and established safe working practices. All this will usually be consistent within the employer or its own security policy domain operators and stick method statements / or procedures.
Nevertheless, safety in confined spaces can easily be compromised by over familiarity with the site, and most of all, the staff not to define a closed space broadly enough.
confined space is a space where there is any restraint to access or egress, or significant confinement at all. Therefore, the space could be quite shallow tank, as a small control unit, etc. enclosed space could be a kiosk or even a shed, if the situation presented a particular risk in that area.
In Wikipedia confined space is defined as follows: “. Closed space concept of the rules for referring in an area attached conditions and limited access to make it dangerous”
So, the definition is very broad. Please note -. In each country, the readers have to refer to their own local regulations
In a confined space, the right approach to access and exit is important, but awareness of some of the basic equipment involved is often lacking. It is clear from our experience that people are regularly in and out of a confined space without using the right combination of equipment.
In recent years, workers have even been known to reduce one of the shafts with nothing more than a rope. But, more often, bring errors even when the right equipment is available.
Many confined space in landfill industry are accessed through a vertical shaft, perhaps the simplest example of manholes. This can be especially dangerous in a landfill where landfill gas could be present – if it may be the ATEX and DSEA Regulations (DSEAR) apply in the UK and national funds DSEAR apply throughout Europe
(. In all references that follow refer to UK rules as stated earlier – .. all readers encouragement accession process this article to refer to their own local rules)
Of course, the entry of the manhole as it means to work at height Regulations 2005 would have to be considered.
A suitable approach would likely include full-body harness, with front-and-rear D attachment points, a fall arrest block, and mounting position as a tripod.
To fully in accordance with Regulation 5 of the confined space regulation in 1997, it must be “appropriate and adequate arrangements for the rescue of persons in an emergency.” The fall-arrest block should incorporate recovery system, to be unfit person to be retrieved
This system requires secondary backup to guard against catastrophic failure of the primary system -. That is, winch.
Clearly, the first mode of entry -. steps or stairs provide the primary means of access, egress and escape in an emergency
In both modes of entry, a full body harness is the necessary equipment.
Full-body harnesses, used for fall arrest, must meet the EN 361 standard and, as a minimum, be a back D attachment point.
in front of the D attachment point can also be used for fall-arrest order, if used. The attachment point can only be used to access / egress, rescue and retrieval purposes. Some higher specification harnesses are also waist belt
