Welcome to our Free Confined Space Entry Training Blog POST #1 - Welcome to the very first post on our brand-new Confined Space Entry Training Blog. As the name implies, this free confined space training blog is dedicated to helping readers achieve a better understanding of the requirements of the Federal OSHA permit-required confined space entry standards. And not just a cursory understanding, but an in-depth understanding on a broad range of confined space-related topics. Areas covered in our free confined space training blog will include, but not be limited to, OSHA's requirements for employers' confined space entry programs, confined ...

POST #2 - Special care and attention must be given when determining which OSHA requirements for confined space entry apply to your specific work situation. Federal OSHA health and safety regulations pertaining to confined space entry operations can be found in the 29th Code of Federal Regulations, or CFR. More specifically, the Federal OSHA confined space entry standards are located in three different parts of the CFR. Those are: The Part 1910.146 confined space standards, which apply to general industry operations; The Part 1915 confined space standards, which apply to the maritime industries; and, The Part 1926 subpart AA confined ...

Post #3 - In the previous post to the confined space training blog, I identified various OSHA standards governing confined space entry work for construction and general industry work (as well as the maritime industry). However, many of the terms used in these confined space standards are not well defined, if defined at all, whereas other parts of these standards are vague and seem to be open to interpretation. These issues often lead to uncertainty about whether or not you are in compliance with the requirements of the OSHA confined space entry standard. Fortunately, OSHA provides many key documents that ...

Post #4 – As mentioned in an earlier blog post (#2), OSHA has three different sets of confined space entry standards; one applies to construction work, and another applies to general industry work. OSHA also have a standard that applies to confined space work conducted in the Maritime industry, but that standard will not be discussed in this blog post. It is imperative that you understand which of the OSHA standards apply to your particular confined space entry operations, and conversely, which one does not, as the requirements of each standard differ. And the way to make sure you understand ...

Post #5 – The success of an organization’s confined space entry program is ultimately predicated on having a competent person with the ability to identify and evaluate the confined spaces at their work sites to determine whether or not they meet the OSHA definition of a permit-required confined space. And that takes a person with sufficient training and experience to do the job right. But exactly whose job is it to identify and evaluate confined spaces? Here’s what the OSHA confined space regulations say about that. OSHA Requirements to Evaluate Confined Spaces The first paragraphs from the general requirements sections ...

Post #6 – Why is it paramount that you understand the OSHA confined space definition? Because OSHA regulates entry into permit-required confined spaces, and the only way to know if you have a permit-required confined space is to first understand whether or not you are even dealing with a confined space as defined by OSHA in their standards. As you dig deeper into the OSHA confined space standards, you will come to realize that, in addition to the common question of what is the OSHA definition of a confined space, you will no doubt find yourself asking several other questions, ...

Post #7 – In the previous post to the Confined Space Training Blog (#6), we examined the OSHA definition of a confined space, with in-depth explanations of the three criteria that make up a confined space per the definitions in the OSHA 1910 and 1926 confined space regulations. In this post, we will follow up by providing several examples of potential confined spaces you may find in the workplace; some expected, and some not. Keep in mind that while these examples list below are but a few of the different types of confined spaces that could be present in the ...

Blog Post #8 – In this post to The Confined Space Training Blog, we will discuss the differences between a confined space that meets the Federal OSHA definition of a permit-required confined space versus one that can be classified as a non-permit required confined space. Why make the distinction between permit and non-permit required confined spaces? Because entry into that space classified as a permit-required confined space is only allowed under an entry program meeting all pertinent requirements of the OSHA permit-required confined space entry standard. However, confined spaces that do not meet the OSHA definition of a permit space, ...

 Blog Post #9 – In previous blog posts, we discussed how to identify confined spaces, and provided several examples of such spaces. Next we will examine the factors that determine whether or not each confined space identified at your workplace must be classified as a permit-required confined space, starting with a hazardous atmosphere that contains a flammable gas, vapor, or mist in excess of 10% of its lower flammable limit, or LFL.  OSHA Definition of a Permit-required Confined Space The Federal OSHA definition of a permit-required confined space for general industry can be found in 1910.146, paragraph B, titled definitions, ...

 Blog Post #10 – In this post, we will examine the second category listed in the Federal OSHA definition for a hazardous atmosphere, which is an atmosphere with airborne combustible dust at a concentration that meets or exceeds its LFL (which stands for Lower Flammable Limit). LFL represents the minimum quantity of combustible dust that must be suspended in the air within the space to be able to cause a flash fire or dust explosion if ignited. In these conditions, the airborne dust is considered to have met or exceeded its lower flammable limit, or LFL. OSHA’s 5-foot Rule of ...

Blog Post #11 – In this post to The Confined Space Training Blog, we will examine the third category listed in the Federal OSHA definition for a hazardous atmosphere, which is an atmospheric concentration of oxygen less than 19.5%, or greater than 23.5%. Atmospheric Composition Oxygen is critical to support human life. However, under normal conditions, over 78 percent of the air we breathe is actually comprised of nitrogen, which is an inert gas. And oxygen, commonly referred to as O2, makes up approximately 20.9% of the atmosphere. If oxygen levels were to fluctuate slightly, there would most likely be ...

Blog Post #12 – In this post to The Confined Space Training Blog, we will examine the fourth category listed in the Federal OSHA definition for a hazardous atmosphere, which is an atmosphere that contains any toxic substance present in quantity greater than its permissible exposure limit, or PEL. Before moving on, make certain to pay close attention to an important footnote to this definition in the OSHA definition section for this standard. OSHA states that this category of hazardous atmosphere only applies “if the topic substance can cause death, incapacitation, impairment in ability to self-rescue, injury, or acute illness ...
