What is a Non Permit-Required Confined Space Checklist?

A non permit-required confined space checklist is a document used to assess and confirm that a confined space is safe to enter without the need for a permit or an attendant. The primary goal is to make sure that confined spaced does not contain hazards that can cause serious harm or death. The use of this form aims to mitigate risks and ensure the safety of workers in confined spaces.

What is a Non Permit-Required Confined Space?

According to the US Occupational Safety and Health Administration (OSHA), a non-permit confined space is any confined space that is not likely to cause harm to workers through atmospheric, mechanical, fire, or gaseous hazards. It is a place where hazards are “eliminated” enough to cause little to no risk to humans.

However, it’s important to note that even in non permit-required confined spaces, potential dangers might still exist due to factors such as:

  • limited entry and exit points;

  • confined movement; and

  • the presence or condition of certain work-related machinery.

Employers are still responsible for ensuring that workers receive proper training, are equipped with necessary safety protection, and follow established safety protocols. Regular assessments of the space’s conditions should also be conducted to verify that no unexpected hazards have emerged.

Importance of Using a Checklist for Confined Space Safety

It is important to keep non permit-required confined spaces free from hazards at all times, as changes in the amount and kinds of hazards will require employers to reevaluate that space. A non permit-required confined space checklist is essential in keeping said space in a safe working condition.

With the right checklist, you can ensure all non permit-required confined spaces are free of hazardous and harmful substances and practices. It can also help you document any possible risks that may happen or be spotted.

Additionally, by standardizing procedures through the checklist, there is consistency in the safety measures taken across different non permit-required confined spaces. In the process, it also helps in training and educating employees on the proper procedures and precautions to take when entering confined spaces, ensuring that there is no ambiguity in safety expectations. As a result, the risk of accidents is significantly reduced.

Furthermore, the checklist promotes and improves both compliance and accountability. Responsible individuals can verify that each step has been completed before granting entry, minimizing the chances of errors that could lead to accidents or injuries. At the same time, this ensures compliance with safety guidelines set by the employer, the area’s safety professionals, and international standards.

What to Include in a Non Permit-Required Confined Space Checklist

To ensure your non permit-required confined space is safe for use and work, create a checklist that includes fields for the following:

  • Evaluating if any new hazards will be introduced to the confined space from:

    • Work tasks

    • Chemicals

    • Equipment

    • Air monitors

  • Ensuring gasses such as the following are at safe working levels

    • Oxygen

    • Hydrogen sulfide

    • Carbon monoxide

    • Lower Explosive Limit (LEL) or Lower Flammable Limit (LFL)

  • Making sure the following are not present or are controlled so as to not cause harm or create other hazards:

    • Materials that can engulf different items

    • Exposed or unmaintained equipment

    • Stray electrical equipment

    • Unmanaged fall hazards

    • Asbestos or asbestos-generating materials
