Locking confined spaces correctly

What is a confined space?

A confined space is defined as a fully or partially enclosed area that is not designed for long-term employee occupancy, but can be used temporarily for maintenance work. These spaces, present in sectors such as agriculture, food industry, chemical industry, sewage, waste, transport and property, constitute a hazardous working environment due to factors such as confinement, liquids, chemical residues, lack of ventilation, and the nature of the work to be performed.



Carrying out work in confined spaces

Because of the limited space in confined spaces, workers experience significant difficulties while working. Access is often restricted and once inside, freedom of movement is severely hampered. This not only limits the ability to react quickly in emergencies, but also complicates rescue operations for supervisors.


Working in confined spaces is unpredictable and carries additional risks. Changes can occur quickly when carrying out work, such as the release of toxic substances, or due to external factors, such as a sudden rise in water levels. As a result, worker safety is no longer guaranteed, making it necessary to leave the room as soon as possible, even under even more complex conditions.



The risks of working in a confined space

In addition, confined spaces often have weak or even absent ventilation, with low oxygen levels and limited fresh air supply. Breathing without a respiratory mask is sometimes not possible, and the spread of toxic substances during work quickly reduces the available oxygen. This again poses a serious danger to the worker.


Working in confined spaces entails significant risks, including limited access and freedom of movement, difficulties in emergency evacuations, and the unpredictable nature of the environment. Ventilation is often weak or absent, resulting in low oxygen levels and toxic releases. Risks include asphyxia, poisoning, electrocution, falls, collapse, drowning, fire, explosion, hearing problems, thermal hazards and unpredictable accident complications.


Due to the risks posed by the confined space, it is essential to ensure that no accidents occur around the confined space. A work permit is therefore required in most cases. For added safety, it is strongly recommended that access to confined spaces be closed and locked.
