In both construction and general industry, a “Confined Space" is defined as a space that is “large enough for an employee to enter fully and perform assigned work, not designed for continuous occupancy by the employee, limited or restricted in the means of entry and exit.” An example of a confined space would include but aren’t limited to: tanks, storage bins, underground vaults, pits, diked areas, vessels, and silos.
These spaces have configurations that hinder the activities of employees who must enter, work in, and exit them. This required training for construction is OSHA 29 CFR 1926, Subpart AA and for other industries, confined space entry is regulated under 29 CFR 1910.146.
Confined Space Training provides you with the knowledge and understanding of OSHA guidelines and how to protect yourself, your coworkers, or anyone you supervise while working in a confined space environment. This OSHA training is provided to prevent injury, illness, or death from common confined space hazards.
Why are confined spaces considered dangerous?
Confined spaces tend to be dangerous because they're difficult to exit quickly in an emergency and your mobility is limited while you're inside. Their nature also hinders effective communication or rescue. Finally, the close quarters and restricted airflow make it easier for heat, gas, and other hazards to build up or fill the space.
What are the hazards of working in a confined space?
Asphyxiation is the leading cause of death in confined spaces. Many conditions common to confined spaces can lead to asphyxiation: oxygen deficiency, toxic atmosphere buildup, drowning or engulfment in fine particulate matter, and torso compression.
It's also possible to get trapped in confined spaces either by getting stuck in place or if your exit becomes blocked. Additionally, confined spaces amplify the hazards of whatever type of work you're performing. Noise, heat or cold, sparks, fumes, and visibility hindrances can all become a threat in a confined space very quickly.
What is an OSHA “Permit-Required Confined Space” (PRCS)?
A confined space permit is required by OSHA if the confined space has one or more of the following characteristics:
- Has the potential OR contains a hazardous atmosphere (examples include: Hydrogen Sulfide, Carbon Monoxide or Dioxide, Flammable Atmosphere)
- The space contains a material the has the ability to engulf someone who enters the space (examples include: grains, sand, dirt, water)
- The internal configuration, layout, or arrangement could cause an employee or anyone that enters to be trapped or asphyxiated (examples include: vaults, large-ovens, underground pits)
- There are any other recognized serious safety or health hazards (examples include: wildlife, electrical or trip hazards, struck-by or fall hazards)
