Help! Can someone remind me the basics of what to do with 5.1 / 5.2.
Agency phoned up with a possible job for me, but its 2years since I did my ADR and I’ve never done any class5, mostly did class 1 and 4 
Looked everywhere but can’t find my core modules coursebook either.
Thanks in advance 
Spoke to dd he on his way to oxford but will answer this later when he can get online
Hope this will be ok
thanks very much 
Class 5.1 Oxidising agents
Class 5.2 Organic peroxides
Don’t suppose that is any help… is it 
I already knew that 
Was hoping for some info on safe handling and what to do with spillages, what kit to carry with you etc
Most of my ADR work has been explosives so I guess I know most of it already, keep away from fire etc

In that case you definitely need dieseldave
Dont spill it on your socks or take your pipe off and let any drips land on timber floors or vegetation 
It is also used for making dark haired women dumb or for cleaning your ears out
Well sorry for wasting your time you nice people, The agency didn’t phone me back to confirm the job so looks like i’m unwanted. Again sorry for wasting your time 
I’ll just go away now

Not a waste of time at all
DD does not got access to net at the moment but will try tomorrow and will reply for future reference
Not a problem at all
Sorry ROG beat you to it

Hi Lycanthrope, OK, here goes. Even though you don’t now need it.
The headmaster would like to know how you lost your schoolbook
These substances and articles contain oxygen and are therefore capable of starting or supporting fires, even in enclosed spaces, when they come into contact with something capable of being burned. (Fuel.)
Some oxidisers have a secondary hazard, such as corrosivity. Some 5.1s are a liquid, whilst some other 5.1s are a solid.
PPE for class 5.1 will include protection for your skin (people count as fuel 
) and eyes, so goggles and gloves will be the minimum, but the appropriate level of protection will be written on your Instructions In Writing (Tremcard.)
Oxidisers conform to the notion of packing groups (PGs) where
PGI = high danger
PGII = medium danger
PGIII = low danger
5.1s are assigned to packing groups dependant on their oxygen content and how easily / quickly they release the oxygen.
5.1s must not be carried near to any other dangerous goods that have a flame symbol on the label, therefore adequate segregation should be implemented in such a case.
New 5.2
Organic Peroxides are similar to Oxidisers in that they contain oxygen, but 5.2s come with their own fuel too.
To say that 5.2s are sensitive to heat is an understatement.
If you remember the fire triangle, you’ll see that chemically, 5.2s are living life right on the edge.
Due to the sensitivity of most 5.2s, they do not fit the notion of packing groups, but instead are assigned to one of seven bands of danger, these being expressed using the letters A - G.
5.2s all end up in Transport Categories, with ADR load “trigger” limits, just like other dangerous goods, but they are placed in the transport category by their specific UN number. As a rough rule of thumb, most 5.2s are in transport category 1, whilst the rest are in transport category 2.
Some 5.2s are so sensitive that they must have an explosive label as a secondary hazard. In most cases of this type, the load must legally be carried in a fridge truck. 5.2s are one of the few classes that, in some cases, also have an upper load limit per vehicle. (Like explosives.)
Another possible secondary hazard of 5.2s is that they might also be corrosive.
5.2s should also be segregated from any other dangerous goods that have a flame symbol in the top half of their label.
The PPE requirement for 5.2s is much the same as for 5.1s, but there is EXTREME danger for eyes in contact with any 5.2 substance.
A little not about the 5.2 labels. On 01/01/07, a new label came out for 5.2s. This has the appearance of the bottom half of the old label, combined with the top half of a class 3 label. The old (all yellow) label may continue to be unsed until 31/12/10, so you might see either kind. Please don’t get confused, because they both have the same meaning.
Spill kits for classes 5.1 and 5.2 must be as per the Instructions In Writing as a MINIMUM, so anything you have over and above that is just fine.
I hope this helps.
To animal: Thanks for letting me know.
dieseldave:
Thanks for the fantastic reply DieselDave, I kindly loaned my booket to another employee at my last company, and never recieved it back 
Your post is great and I’ll print it off and might help me in the future I hope
Slight problem is the agency contacted me again regards the job, and they made a mistake, its actually Class 6.2 Infectious substances I believe. Luckily I have all of the classes so that won’t present a problem, just need to remember how to handle this stuff. Think I can borrow a book from a relative to look at Thanks so much for your help and posts, and sorry for wasting your time.

I would be a bit worried about your agency, a mistake that big could be fatal.
6.2 infectious substances may contain pathogens & micro organisms which could include, virus, bacteria, cultures, clinical waste and specimens.
Do you really want to be responsible for the next epidemic of Bubonic Plague or even Foot and Mouth disease?
I hope they are paying you £25 an hour
Wheel Nut:
I hope they are paying you £25 an hour
sadly not, but beggars can’t be choosers, if they want to give me a job I’m happy to take it, anything to get some experience on the road and money in my pocket
And the agency thing getting confused was probably to do with talking to two different offices, the local office at lincoln contacted me about a job in Nottingham, and got the Notts office to call and give me further details
I’ll let you all know what happens thanks a lot for your help, much appreciated.
Diesel Dave…would i be right in saying that most 5.2’s are carried refrigerated due to their (probable) Self Accelerating Decomposition Temperature?
GlesgaBill:
Self Accelerating Decomposition Temperature?
I once had a load of mushrooms that did that.
I know. I’ll get my coat. 
Wheel Nut:

Agreed Wheel Nut.
It could be a mistake at the customer’s end though.
From my experience, I share your concern about agency staff dealing with bookings for ADR regulated jobs.
Many of them simply haven’t a clue, they seem to suspect that there’s something missing, yet they do nothing about it…
Wheel Nut:
6.2 infectious substances may contain pathogens & micro organisms which could include, virus, bacteria, cultures, clinical waste and specimens.
That’s a fair summary of class 6.2, but here is what ADR says about it: (I think your quote is from elsewhere. )
In ADR is:
The heading of Class 6.2 covers infectious substances. For the purposes of ADR, infectious substances are substances which are known or are reasonably expected to contain pathogens.Pathogens are defined as microorganisms (including bacteria, viruses, rickettsiae, parasites, fungi) and other agents such as prions, which can cause disease in humans or animals.
Also included in class 6.2 are:
Biological products, cultures, Genetically Modified Microorganisms (GMMOs) and organisms, Medical or clinical wastes and Patient specimens.
TIP: Packages bearing white (class 6) labels should be kept well away from your butties.

Hi GlesgaBill.
Blimey, you’ve remembered SADT so long after taking your course.
As a rough rule of thumb, if a 5.2 has an SADT of 50 deg C, then it is subject to temperature control requirements.
That’s not hard and fast though, because for some 5.2s, the fridge requirement kicks in with an SADT of 45 deg C.
These types of organic peroxides sometimes have an ‘explosive’ secondary hazard and a “1” label next to the 5.2 label on the packages.
IMHO, a pair of spiked running shoes should be added to the PPE list for these.
