Confined spaces are usually broken down into two groups: Non-Permit and Permit. Permit confined spaces are the most hazardous and require you or some qualified person to completed a safety checklist, simply called a permit, before you enter in to the space.

What are the types of confined space?
Confined spaces include, but are not limited to, tanks, vessels, silos, storage bins, hoppers, vaults, pits, manholes, tunnels, equipment housings, ductwork, pipelines, etc.
What are the two classifications for confined spaces?
Confined spaces may be classified into two categories: (1) open-topped enclosures with depths that restrict the natural movement of air (e.g., degreasers, pits, selected types of tanks and excavations), and (2) enclosures with limited openings for entry and exit (e.g., sewers, tanks and silo).
What 3 things define a confined space?
According to OSHA a confined space is a space that meets these criteria: 1) being large enough for an employee to enter and perform work; 2) has limited or restricted means for entry or exit; and 3) is not designed for continuous occupancy.
What are examples of confined spaces and enclosed spaces?
A confined space is any enclosed or partially enclosed structure that is intended or likely to be entered by any person, has limited or restricted entry or exit access and contains a potentially harmful atmosphere. Examples include tanks, pits, chimneys, silos, underground sewers, tunnels and wells.
What is confined space as per OSHA?
Definitions. confined space: A space that has limited or restricted means of entry, is not designed for continuous occupancy, and is large enough and configured so that a person can enter the space and maneuver well enough to perform tasks.
What is defined as confined space?
Confined space means a space that: (1) Is large enough and so configured that an employee can bodily enter and perform assigned work; and. (2) Has limited or restricted means for entry or exit (for example, tanks, vessels, silos, storage bins, hoppers, vaults, and pits are spaces that may have limited means of entry.
How many levels are there in confined space?
There are two levels to pay attention to when measuring combustible gases: Lower Explosive Limit (LEL): This is the lowest concentration of a gas in the air that can combust or produce a flame when paired with an ignition source.
What type of hazard is confined spaces?
What are the hazards associated with confined spaces? An excess of oxygen, in the presence of combustible materials, results in an increased risk of fire and explosion. Some materials, which do not burn in air, may burn vigorously or even spontaneously in an enriched oxygen atmosphere.
What is a Class C confined space?
Confined Space, Class “C” A confined space in which the potential. hazard would not require any special modification of the work procedure.
What is the depth of a confined space?
four feet
Confined spaces include any space that has an open top enclosure of more than four feet in depth which restricts the natural movement of air and enclosures with extremely limited openings for entry or exit.
Can a room be a confined space?
HSE does include “unventilated or poorly ventilated rooms” as an example of a confined space in their guidance on the Regulations in their guidance leaflet, indg258 .
What are 3 different types of hazards in confined spaces?
Hazards associated with confined spaces include oxygen deficiency, toxic vapours and combustible gases, solvents or dusts. In addition to atmospheric hazards, confined spaces often contain physical or mechanical hazards such as rotating machinery, electrical equipment or material which can engulf an entrant.
What PPE is required for confined space entry?
Chemical- and liquid-resistant gloves iv. Insulating rubber gloves c. Care of Gloves i. Protective gloves should be inspected before each use to ensure that they are not torn, punctured or made ineffective in any way.
What is confined space in the workplace?
A confined space is any enclosed or partially enclosed structure that is intended or likely to be entered by any person, has limited or restricted entry or exit access and contains a potentially harmful atmosphere. Examples include tanks, pits, chimneys, silos, underground sewers, tunnels and wells.
What are the 4 characteristics of a permit required confined space?
A permit-required confined space is one that meets the definition of a confined space and has one or more of these characteristics: (1) contains or has the potential to contain a hazardous atmosphere, (2) contains a material that has the potential for engulfing an entrant, (3) has an internal configuration that might
What is the meaning of LEL OSHA?
Lower explosive limit
Lower explosive limit (LEL) means the minimum concentration of vapor in air below which propagation of a flame does not occur in the presence of an ignition source.
What is the confined space procedure?
The confined space permit
- Visibility of confined space work.
- Prior identification of confined spaces in a register and enforcing special rules.
- Specific elevated risks for long-running equipment.
- Ensuring work is done by competent people trained in the task.
- The role of the spotter.
- Gas testing in confined spaces.
What is hazards and risk?
A hazard is anything that could cause harm. And, risk, is a combination of two things – the chance that the hazard will cause harm and how serious that harm could be.
Who can enter a confined space?
The regulations identify the ‘competent person’ as being the person making the critical decisions about entry and the protective measures to be taken. Employers must select personnel who are ‘suitable’ to enter and work in confined spaces and these people must undergo adequate training in what to expect.
What percent LEL is safe?
Atmospheres with a concentration of flammable vapors at or above 10 percent of the lower explosive limit (LEL) are considered hazardous when located in confined spaces. However, atmospheres with flammable vapors below 10 percent of the LEL are not necessarily safe.
