Confined Space Inventory Development




Developing a Confined Space
Inventory List

Working in confined spaces is one of the more dangerous elements on job sites. Working safely in confined spaces requires that a strict safety process and aa series of precautions be followed. 85% of confined space accidents are preventable – so long as workers are educated about job hazards & have a structure in place that is tasked towards prevention. An important part of confined space safety is the establishing, maintaining and updating of a confined space inventory.

The first step in the process is setting out to detail a list of all confined spaces on the job site, premises, campus, etc. It is important that management and all appropriate supervisors and staff are aware of such spaces and the inherent danger that they may bring. This does not mean that work cannot be performed in these spaces; so long as the spaces have been identified and inventoried – and proper confined space training has been given – authorized personnel may perform work in these spaces as needed.

Securing a Confined Space Entry Permit, Working Safely Within

Once confined spaces are identified and inventoried, the organization can then establish these as permit-required confined spaces (PRCS). This is necessary to ensure that anyone with a confined space entry permit has received proper training on working in confined spaces and has been briefed as to the nature of this particular confined space, its configuration and inherent risks and hazards. Confined Space Inventory identifies hazardous environments, configurations and/or materials; and whether any other safety or health hazards are present.

At Advanced Consulting and Training, we can put together a Confined Space Inventory program for your organization or work site. We also offer training courses and consulting in confined space inventory. This way your company or organization can work safely and be in compliance with workplace safety laws, regulations and best practices. Contact us today to find out more and ensure that your operations in confined space entry are safe and compliant.



A confined space is a space with limited entry. This is not suitable for workers as it poses a health and safety risk.
  • Limited entry & exit
  • The space is not intended for human occupancy – meaning the space was designed to hold something other than people
  • The space IS large enough for a worker to fit inside and conduct work. If the space is too small for a human to fit inside, this does not pose any risk as no one can become trapped within the space
The main dangers surrounding confined spaces in a workplace is reduced oxygen levels, risk of fire, flooding/drowning or asphyxiation from contaminants that may be present in the confined space. The above risks are heightened in a confined space as it provides limited entry and exit to the worker. While the above-mentioned risks can happen anywhere on a job site, limiting your employee’s ability to remove themselves from danger goes against the health and safety regulations.
