Blast It Clean Confined Space Safety

Providing Nationwide Confined Space Cleaning


A confined space is an enclosed area that has limited access used to enter and exit in order to perform work. Because of limited means of entry and exit, hazards may become present and can be harmful or even fatal for individuals who enter them. Confined spaces are typically designed for purposes such as storage, maintenance, or inspection, and can be found in various environments, including industrial facilities, construction sites, agriculture, and more. Common examples of confined spaces are silos, storage bins, vaults, cold storage, ship holds, manholes, tanks, attics, crawl spaces, tunnels, and certain types of equipment or machinery.

Confined spaces may have inadequate ventilation, which can lead to the accumulation of hazardous gasses, fumes, or airborne contaminants. Confined spaces can contain various hazards such as toxic gasses, flammable materials, engulfment risks, or physical hazards. These hazards can pose significant dangers to anyone inside the space.

With confined space, the Occupational Safety and Health Administration (OSHA) requires an evaluation of the workspace to determine if risks are present that could result in serious health issues or even death. If those conditions are present, it is considered a permit-required confined space. A permit-required confined space is anything that contains or has the potential to contain a hazardous atmosphere, contains material with the potential to engulf someone entering the space, has an internal configuration that might cause an entrant to be trapped or asphyxiated, or contains any other safety or health concerns. OSHA requires these specific guidelines and regulations for working in confined spaces to protect the safety and health of workers.

It’s important to be made aware of the specific characteristics and hazards associated with confined spaces and to follow safety protocols, which may include permits, training, and equipment when entering or working in such areas to prevent accidents and ensure the well-being of individuals involved.


Entering a confined space can be hazardous, especially when adding abrasive blasting. Limited entry means limited ability for ventilation. If a hazardous gas is present, the impact can be quick and the ability to escape the toxic environment can be delayed or difficult. The blasting process itself can also contribute to contaminants entering the air and poisoning the atmosphere within the space.

The challenges of mobility when blasting in a confined space can be overwhelming. Not only do you have to overcome getting in the space and being able to move around, but many times you also have additional equipment that creates waste from residue removal or as a byproduct of the blasting and then has to be removed using restricted means. It's crucial to follow specific safety procedures to protect the health and safety of individuals involved.

The exact procedures may vary depending on the location, type of confined space, and applicable regulations, but the following graphic below shows the most common steps and guidelines for entering a confined space safely.

Atmospheric hazards are the primary cause of unfavorable outcomes due to working in confined spaces. Harmful gasses can be colorless and odorless without instrument testing. Monitoring oxygen levels is also important and should be completed before entry. Blast hoods are required for all blasters as part of their PPE and are used as a safety precaution.

Once the confined space has been evaluated for risk, it’s important to isolate the space to prevent controllable hazards. Power to any equipment associated with the confined space must be disabled. This method is referred to as lockout/tagout. 

Once in a confined space, you have to be able to see what you are doing. Natural light is not always available due to restricted openings so it’s important to have a portable light solution that is “hands-free” so that workers are still able to operate equipment and perform work. Lack of lighting and improper processes in confined spaces can create fear and put individuals in heightened emotional states. 

Ensuring that emergency services, such as rescue teams, are readily available if needed is also important. Even with training and precautions, you will find it to be best practice to make the local fire department aware of any job performed in a confined space and that they have a safety extraction team. It’s important to always check and adhere to the specific regulations and guidelines of your region, as they may have additional requirements or variations in procedures for confined space entry. Safety is paramount when working in confined spaces, and a comprehensive approach is essential to mitigate risks effectively. 

Confined space can be scary and intimidating, but putting proper safety controls in place can reduce risks and enable quick action to minimize disastrous situations.


Call on your trusted leaders in the industrial cleaning service industry to be there for your confined space projects. Working in confined spaces is something Blast It Clean does nearly every week. Due to the nature of our work, PPE is already a standard requirement. Our company emphasizes safety first and is familiar with the risks and steps we can take to minimize them. 

We offer a helping hand in keeping your valuable assets and work environments in top shape. As a leader in abrasive blasting, a process that uses high-pressure materials like sand, grit, or other abrasive media to clean and prepare surfaces, confined space can be vital. In confined spaces, this process can be vital for removing rust, corrosion, old coatings, and contaminants from surfaces to ensure they are safe and ready for maintenance or inspections. It doesn’t matter if it's a one-time silo restoration or a weekly tank cleaning, confined space safety must be followed.
