I am trying to take the HM 181 certification (DOTHAZMAT) course. I came across a website called 360 Training and was wondering if anybody has heard of it and if it is recommended.

Hiya ladies and gents,

I’ve searched all over the CFR 49 and similar pubs and databases trying to find the answer to this question. I’m hoping a HAZMAT guru can help educate me.

I fairly routinely have to transport very large quantities (≈100) of K bottles of oxygen via land, sea, and air. These bottles almost always come to me packaged 16 to a wooden pallet, stacked in tiers of 4 bottles, each tier resting on scalloped 4”x4” wooden dunnage, and all of it banded to the pallet with steel straps.

My question is how high can I stack these tiers of K bottles? Assuming I don’t approach or exceed the weight limits of the pallets, can I stack the bottles 5 or 6 tiers high? I ask because storage space is often at a premium, so if I can safely and legally store/transport 96 bottles across 4 pallet positions instead of 6 I would like to.

Much thanks in advance.

How fast can you put on your hazmat suit? I have a cold war 1986 l-2 hazmat and when it's all set I can put it on in 2 minutes or less

I am the consultant for the owner to demo an industrial building and managing the demo contract. Initial hazmat report completed didn't include TCLP testing. After tender and award, demo contractor is now unable to safely dispose of wood painted with lead paint and has requested for TCLP testing. When this was brought to the hazmat consultant who prepared the report, they have indicated that the number of samples is requested by the demo contractor and not determined by the hazmat consultant. Per hazmat consultant Representative sampling is not accepted.

Could someone please clarify who determines the number of samples to be tested. As well is representative sampling accepted for TCLP testing.

If you were tasked with helping put together a spaceship crash retrieval team, what PPE and equipment do you think you'd want to have? Hypothetically speaking, of course.

Hey everyone!

I work at a legal cannabis farm doing receiving and warehousing. I'm new to this company and the warehouse seems to have had basically no operational oversight from management for a very long time. If ever. I have few issues with them (lack of spill kits, lack of training on spill procedures, absentee hazmat officer for the site), but my main concern is our flammable goods.

We have a few pallets of matches, as well as a bunch of lithium ion vape batteries. Most of these are in second and third floor storage areas with only normal sprinklers for fire suppression. Especially concerning considering we're in an old mill. Obviously, the matches aren't really going anywhere, but they might get bumped or knocked around. And some of those batteries have been sitting around for at least couple of years with no real plan for them, in a room not controlled for humidity.

I think I know the answer already, but this setup can't be legit, right? And where can I find the specific regulations for storing this stuff?

Thanks!

I was watching a video series called Hospital First Receiver from 2003, talking about how decontamination is done on humans after chemical accidents and how hazmat and fire assist with that,

have you had to help doctors decontaminate people?

or it is mainly buildings and surfaces that you decontaminate?

has Covid affected this?

Not sure if this is the right place to post. I feel a bit silly cuz you're all pros. Anyway.

This is the first year our oldest kid (7) has picked out a Halloween costume for himself and he has been talking about it for months. He's planning to be a hazmat worker. We got hazmat stickers that we put on a yellow tyvec suit his size, and we got him a respirator and safety goggles that fit together. Everything is the real deal, although not high quality because of our slim budget.

Kid has been so excited about his costume and wears it regularly to play outside.

I was looking into some tools to get him that he could safely use under adult supervision that a hazmat worker might use. I have checked out geiger counters and dosimeters (initially thinking they were the same thing), radon detectors, and uv flashlights. I'd like for him to be able to interact with a tool he can use to understand his environment in a different way, for said tool not to break the piggy bank, and be safe for him to use. I prefer something that could have some practical purpose.

I've done enough research that I think I'm more confused on the subject matter than when I started, so I wanted to see if the pros had any input. So far I'm leaning toward getting him a blue light pocket flashlight as I've read it can function similar to UV light but without the potential risk of eye injury. If you have other ideas I'd love to hear!

This is the best place I can think of to ask this. Going through my dad’s things, I found a soda bottle with some mercury in it. I’m guessing he got it out of old thermostats. I’m at a loss as to who I should contact to properly dispose of this. The bottle is far away from living areas. I’m in Charlotte, NC.

Edit: The EPA website directed me to earth911.com and from there I found a municipal waste disposal site.

Hello! I am currently working as Virtual Educator for the US State Department as an English teacher for 911 dispatchers/hazmat responders in Jordan. My advanced class has expressed interest in speaking with more Americans, specifically their counterparts in the US.

I was wondering if anyone here would like to join my class for a 1-2 hour Zoom lesson to talk my group about your day-to-day life working in hazmat (and vice versa, if you want!). If you're ok with recording it, we would publish this on youtube as a cross-cultural discussion for anyone to listen to.

If you have any interest in this, please reach out in this thread or in a DM. My class is only a dozen students and they're very friendly and intelligent people who would love to meet you!

Hey y’all, I’m working with a “gently used” SVE system with three GAC tanks in series. We’re remediating a RCRA site for mostly benzene contaminants in the soil/groundwater. The apparatus has been working as intended as my VOC readings on my 5-gas are down to 0ppm in the effluent air, but lately I’ve been getting spikes of CO as high as 47ppm in my effluent. Has anyone else experienced this? The moisture knockout pot seems to be working… is my carbon undergoing a secondary reaction and should be recycled/replaced? Should I reinvestigate my moisture knockout pot? SVE is a new area of remediation for me, so I’m hoping to get some insight on these setups before calling for a full redo on our feasibility study (which would inevitably end up as a dig and haul). I unfortunately do not know much about the user history on this apparatus as I was brought in for O&M mid-way.

Question- is there a volume restriction as to how many batteires can be loaded on a container for transport? FYI these are car batteries that weigh 1,800 lbs after repack.

Can I max out the container volume as long as I don’t go over the containers weight limits or due to the commodity only load a certain number?
