Which of the following is not a confined space that requires a permit?
4. Which of the following is NOT a confined space that requires a permit? A space that contains a hazardous or potentially hazardous atmosphere. A space that contains a material that can smother someone who enters.
What is not a characteristic of a confined space?
The space is not designed for continuous occupancy. The space is partially or completely enclosed. The space has the potential for a hazard to be present.
What are the characteristics of 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.
Which of the following are only characteristics of permit-required confined space?
OSHA uses the term “permit-required confined space” (permit space) to describe a confined space that has one or more of the following characteristics: contains or has the potential to contain a hazardous atmosphere; contains material that has the potential to engulf an entrant; has walls that converge inward or floors …
What are the four main dangers of a 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.
How many types of confined space 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 gases are tested in confined space?
The most common configuration for a multiple-sensor gas monitor is one that can read levels of oxygen, combustible gases, hydrogen sulfide and carbon monoxide. While monitoring oxygen and combustible gas levels is required, toxic gas hazards vary with different types of confined spaces.
What is the OSHA standard for confined space?
OSHA’s standard for confined spaces (29 CFR 1910.146) contains the requirements for practices and procedures to protect employ-ees in general industry from the hazards of entering permit spaces. Employers in general industry must evaluate their workplaces to determine if spaces are permit spaces.
What is the oxygen level in confined space?
Make sure that the oxygen content in the confined space is not enriched. Oxygen content should be less than 23% but maintained at levels greater than 19.5%.
What is an acceptable LEL?
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. Such atmospheres are too lean to burn.
What is a safe level of oxygen?
A normal level of oxygen is usually 95% or higher. Some people with chronic lung disease or sleep apnea can have normal levels around 90%. The “SpO2” reading on a pulse oximeter shows the percentage of oxygen in someone’s blood. If your home SpO2 reading is lower than 95%, call your health care provider.
What is Lel in confined space?
An LEL Confined Space refers to Lower Explosive Limit within the confined space, which will be a percentage of combustible material in a gas or vapor state, that if mixed in the right proportion with air can create a hazardous fuel/air mixture that can be ignited and explode.
What is LEL & UEL?
The minimum concentration of a particular combustible gas or vapor necessary to support its combustion in air is defined as the Lower Explosive Limit (LEL) for that gas. The maximum concentration of a gas or vapor that will burn in air is defined as the Upper Explosive Limit (UEL).
How is Lel calculated?
To compute the LEL of any gas in air, divide the unknown concentration by the LEL listed in the NFPA Handbook. 100% LEL’s for 9 of Gasco’s more common gasses are shown in the table to the left. For example, if you take 2.5% Methane in air and divide it by 100% LEL of methane (5%), the result is 50% LEL.
What is Lel oxygen?
The lower explosive limit (LEL) is the minimum concentration of a specific combustible gas required to fire combustion when in contact with oxygen (air). If the concentration of the gas is below the LEL value, the mix between the gas itself and the air is too weak to spark.
What does LEL mean in gas?
Lower Explosive Limit
Is 19.5 Oxygen safe?
Based on OSHA guidelines, a confined space is considered to have safe oxygen levels if readings are between 20.8-21 percent, while a space with readings of less than 19.5 percent are considered to be oxygen deficient.
What does Lel stand for?

Why do people say Lel instead of LOL?
Unlike what many people think lel is not an acronym in the same fashion that LOL is (it does not mean laughing extremely loud, laughing extra loud or similar). Lel (and variations including lal) resulted from the use of random vowels substituted in place of the ‘o’ in LOL. The word however, in essence, still means LOL.
