What are 3 examples 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 3 characteristics of a confined space?

In order for a work area to be defined as a confined space it must meet all three of the following criteria:

  • Limited Openings for Entry and Exit.
  • The Space is not Intended for Continuous Human Occupancy.
  • The Space is Large Enough for You to Enter and Conduct Work.

What 2 types of confined spaces are there?

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 hazards in confined space?

The hazards associated confined spaces include:

  • Toxic Atmosphere. A toxic atmosphere may cause various acute effects, including impairment of judgement, unconsciousness and death.
  • Oxygen Deficiency.
  • Oxygen Enrichment.
  • Flammable or Explosive Atmospheres.
  • Flowing Liquid or Free Flowing Solids.
  • Excessive Heat.

What are two types of confined spaces?

What equipment is required in confined space?

A tripod (or guardrail, ladder, hoist, or another piece of access equipment) will give you the basis for getting into the confined space, and there are tripod kits with all the equipment you need to begin your confined space work.

What is LEL and UEL in confined space?

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. Upper Explosive Limit (UEL): This is the highest concentration of a gas in the air that can combust or produce a flame when paired with an ignition source.

How to work in a confined space?

Entry and Exit Plan. While it may seem obvious that a worker has to enter and exit the space,doing so isn’t always as easy as it seems.

  • The Atmosphere. Before anyone enters a confined space,the atmosphere must be tested using equipment designed to detect chemicals and gases that may be present.

  • Equipment Function.
  • Confined Space Conditions.

    Is it to be used in firefighting or emergencies?

  • Is it to be used in oxygen-deficient atmospheres (less than 18% oxygen in air; some jurisdictions say below 19.5%)?
  • What is the nature of the hazard (chemical properties,concentration in the air,warning properties)?
  • Is there more than one contaminant (i.e.

    • What are the common hazards in confined space?

  • physical hazards
  • electrical hazards
  • fire hazards

    • What is considered confined space?
