message: I think this article should be merged with Biosafety Level. Both articles contain almost the same info.  —Preceding unsigned comment added by 68.192.35.0 (talk) 19:41, 2 July 2008 (UTC)
replies: text: This article has the potential for expansion much beyond the topic of Biosafety levels.  Any merger should result in the survival of this article and removal of the BioSafety Level article.  Pzavon (talk) 00:52, 4 July 2008 (UTC)

thread_title:  YES it is 

message: Is there a reason why, for Levels 1-3, the first words are "Bacteria and viruses", and for Level 4, the first words are "Viruses and bacteria"? It's the tiniest of issues, but I skimmed over the four levels to see if, for example, 4 had only viruses, and it took a moment to see what happened. ALTON .ıl 04:57, 20 August 2009 (UTC)

message: The main black on yellow image has sharp points, but the symbol with dimensions has points that are squared off according to dimension C. I also feel that the main image should be an SVG not a PNG as
recommended here.

thread_title:  Is one of the images incorrect? 

message: Plant pathogens are necessarily biohazards. They include a versatile kind of slime-moulds, fungi, bacteria, viruses, viroids.  They are hazardous because
* Plant pathogens can spread and destroy food crop plants and agricultural fields. (See also: Famine )
* or can destroy or even wipe-out vegetation and biodiversity (See also : Forest_dieback)
* or can deteriorate stored food grains/cereals, vegetables, etc. that makes the food inedible or toxic and/or distasteful. That can cause financial loss as well as hunger. (See also: Food spoilage , Post-harvest_losses_(vegetables))
* Some plant pathogens and even plant beneficial microbes (some benificial endophytes that promote the plant to grow, without no appearent visible lesion) infect the live plant can make the plant toxic to human and cattle, such as some ergots. 
* Some plant pathogens can cross infect human or cattle, and can be deadly. such as Aspergillus spores. 
* Some plant pathogen spores can survive for prolonged period, so after a prolonged period of unfavourable condition to the micobe when the optimal environmental coditions match the plant pathogens can multiply exponentially and can cause plant disease or famine.  
* Some bacteria such as some rhizobacteria are able to transfer DNA into plants, which get integrated into host plant's DNA. 
So I request to elaborate on plant pathogens as biohazards, and their safe handling methods and regulations.

message: As of 17:56, 14 April 2020,  added COVID-19 to the list of "Bacteria and viruses that can cause severe to fatal disease in humans, but for which vaccines or other treatments exist" in §Levels of biohazard. 
This was not supported by the cited CDC reference: Coronavirus Disease 2019 (COVID-19) > Lab Biosafety Guidelines,Updated March 31, 2020.
I removed the mention and reference.

thread_title:  Symbol graphic with dimensions 

message: With , Captain Cornwall made a bold edit by adding the image and caption at the right. The caption not an accurate summary of the SARS-COV-2 and COVID-19 articles, and frankly reads to me as wp:advocacy for the view that the efffect of COVID-19 is overstated for the large majority of people. The image has the additional problem that an isolated virus does not come with a biohazard warning, such as might be found on bags of clinical waste: it really is not a relevant image for this article. 
Rather than revert it straight away per wp:Bold, Revert, Discuss, I tried to tone down the POV-pushing caption to read "SARS-CoV-2, the cause of COVID-19". The wp:Short description at SARS-Cov-2 reads "Virus strain that causes coronavirus disease 2019 (COVID-19)"
Captain Cornwall reverted this compromise, saying that [this short description] "is debatable", insisting on their version. Consequently I am now reverting the original change per WP:BRD and WP:STATUSQUO. An argument must be made (a) whether or not this image is useful in this article, recalling that "images are to inform, not to decorate" and (b) [if it is] what caption is appropriate, recalling WP:FORK.  --John Maynard Friedman (talk) 15:02, 14 October 2020 (UTC)
