Just seen a story on local TV news.
A woman in Pately Bridge called emergency services after she dropped a mercury thermometer in her kitchen. Fire brigade and paramedics attended the scene and the family has been moved into temporary accommodation whilst the kitchen is decontaminated. Pictures showed kitchen units being dismantled and removed. the cost so far is £5000.
At the end of the article the woman asked "if they are so dangerous why can I buy them at the local shop for £1-99?"
I know mercury is toxic but I don't know enough to say that the reaction was OTT.
How many workplaces have mercury thermometers and if they do are there adequate emergency procedures in place in case of an accident? Will evacuation be part of the procedure?

A lifetime's exposure to mercury vapour will have serious effects (see Alice in Wonderland) but I wouldn't have thought that one thermometer's-worth could justify the response you have described. Of course, the mercury should be cleaned up but wrecking a kitchen to do it seems excessive.

I remember breaking a thermometer in the chemistry lab at school, and I didn't think it had any effect on me. 30 odd years later though a lot of my colleagues think I'm as mad as a hatter.

Perhaps her kitchen units had aluminium in them! Who knows? A bit OTT I suspect, unless you are raking in the money for the clean up.
Aluminium spillages in aircraft kitchens (galley), now thats a different kettle of fish!

One of the original methods of a clean up of mercury, if my memory serves me correctly, was to use an automatic pippete, flowers of sulphur and copious amoumts of water.

Presumably this one contained Mercury in the elemental form but its still OTT. Today's pooters should be connected to a vacuum pump via a trap. You can also use a paste of Calcium hydroxide and flowers of Sulphur in water in equal parts. In my school days we were encouraged to pass the stuff around from hand to hand to experience the specific gravity, etc!

This story was on GMTV this morning - its going to cost in the region of £10,000 for the clean up and cost of replacing furniture - a chemist was called in and he told them their pine dining room table and chairs had to be destroyed.It was dismantled and plaed in sealed bags and siposed of as toxic waste. The family (who haven't been near the house for 4 days)cannot re-enter the house until the chemist has given the all clear.

What a waste of money and a very extreme OTT reaction. I cringed as I watched the story and once again thought about changing professions as I do not want to be categorised as a completley OTT H&S professional

When I was at school someone put some mercury in the physics teachers cup of tea. It gave him a terrible case of the sh#ts but he was back working after the weekend with no long term health effects.

By the way, I am not recommending that anyone re-creates this.

Someone should check their facts and then sue that chemist. I'm out of the office (caen in normandie) so I can't look them up. By memory, The surface tension/evaporation rate of liquid mercury is such that it can give rise to an atmospheric concentration above the 8-hr TLV, depending on the environment. Did anyone actually check/calculate the exposure to the involved family ?

What environmental/occupational health qualifications did that idiot have ? Where did he/she come from ?

I remember someone in biology at school breaking a mercury thermometer and the teacher using 2 pieces of paper, and eventually getting it all onto one piece.

How it was disposed of after that I have no idea!

Have to say that, prior to taking a sideways move to avoid being branded as what others have suspected we will eventually be branded as, I became aware of a local education establishment that dialled 999 when a similar incident occured.

By the time I got to the site there were fire and police vehicles everywhere and all the staff were walking around in disposable paper suits having had their own clothes taken away for decontamination/ destruction.

The building was cleaned from top to bottom using a specialist cleaning company and most of the building contents were either destroyed or sent for similar specialist cleaning operations. All carpets were destroyed.

The common factor would seem to be the emergency services. Once the call came in the incident was treated as a major incident and acted upon accordingly. Total control was assumed by the emergency services although the bill was ultimately met by the Council tax payer.

I do not know what the ultimate answer is but until such time as education of the masses, with particular emphasis on the first responders, ensures a proportionate response to incidents headlines like this will be all too worryingly common place.

I think you have raised an important issue with regard to the somewhat pre-determined and wooden responses of the emergency services to reported incidents.

Whilst we all value and admire the service they provide it often seems that the text book takes over from human initiative.

By way of one example, there was a serious RTA on the motorway leading into Portsmouth a short while ago. The police investigation response was to close the motorway for a very long time - which is one of only three ways in and out of the city. The result was complete gridlock until the early hours of the morning the next day. People could not get to hospital appointments, children could not get home from school. Parents could not reach them. Ferry terminals were blocked, buses full of passengers were stationary for hours, etc, etc. It was only through good fortune that this did not lead to more serious consequences for people needing medical attention, etc.

We really need people in control with authority to use their initiative and the ability to do so wisely.

Happy Wednesday to all.

As an ex-Fire Service Fire Survival & Decontam [HAZMAT for our North American brethren] Instructor with a total of 24yrs at Stations and as a Trainer in the busiest parts of south Essex; perhaps I could provide some background info for responders to this post to consider. It should be unsderstood that I am only relating to my past experience, although I suspect that little of substance has changed in the intervening time; except for suspected terrrorist incidents.

Also, I am not trying to defend or refute any aspect of the reported incident - I am trying to present an impartial & unbiased informative posting.

As an OiC of appliances attending incidents that involved suspected hazardous substances, I was bound by the Brigade rules; the principal ones being to check what potentially uncontrolled substances may be present at the incident without exposing personnel unnecessarily; to relay that information to Control who would then pass that info to the Brigade Chemical Expert [not a direct FS employee] who would then respond with [hopefully] appropriate advice. I was not allowed to initiate any actions on my own initiative unless I perceived an immediate and over-riding life risk - and I was still required not to place those under my control in harms way [these procedures are a book - and not a slim one either].

If it was perceived sufficiently dangerous, the Chemist would either liaise directly with the incident commander or even attend in person.

Firefighters get a considerable grounding and training in recognising & collecting the evidence of hazardous substances and extensive training in how to interact with those substances. Because of the limited space availability on fire engines, and the need to provide the minimum amount of ability to select the wrong level of protection, this inevitably leads to what could very easily be seen with hindsight as an OTT response in many cases. It should be borne in mind that there really is still only an extremely limited range of PPE & RPE immediately available to the first responders; and they are always the ones who really do need the highest level of protection.

The Incident Commander would be advised by the Chemist and then deal with the incident accordingly. In the reported case, there is probably rather more than has so far been reported publicly and I will reserve my opinion as to appropriate the reported actions.

In response to some other responses on this thread; as an OiC at RTA's on even relatively minor roads - which may also involve hazardous substances; I have been present when firefighters have been put at unacceptable risk from passing traffic; and I still have a very clear vision of a colleague being pulled into the slipstream of a passing artic on the A127 at about 20:00hrs one night in the mid-seventies whilst working to extricate the occupants of a crashed car; and then being pulled by that slipstream some 80yds along the road - he broke lots of things in his body before coming to a stop in the centere of the outer lane.

Since that time, I adopted a procedure of simply closing the road that was being worked on with FS vehicles as other provided barriers were not perceived as being effective. From the FS perspective, having ensured the safest possible working environment, it was then the exclusive responsibility of the Police to effectively manage the ensuing traffic issues. the Fire & Rescue Services Act 2004 [replaced the Fire Services Act 1947 & etc] now ratifies that approach and makes the responsibilities explicit.

My apologies for such a lengthy posting; but it never hurts to provide a means for people to have a greater understanding of the underlying reasons or assumptions for doing things.

The fire brigade had long since done their job with my Portsmouth story, Frank, and closing one lane thereafter would have been adequate. I would have hated to have needed to drive a fire appliance into the city that day. I know that it has been known for crews to move a few cars in order to get through but this would have meant lifting a few miles of vehicles onto the footway. Overall situations and associated risks need to be assessed by competent management rather than following weighty text books and absent consultants at times.

Perhaps every mercury thermometer should be supplied with some aluminium foil and a 2 page spill control sheet and an MDS so that we could avoid such situations!!! Ouch bit the wretched tongue and cheek again.

Other alternative is to swop to alcohol thermometers, banning mercury altogether, then when the child bites it and swallows the alcohol we can limit the chaos to a single hospital cubicle and person.

Obviously the dynamic risk assessment aspect of FS training has not reached sufficient state of cultural change so that it can evaluate all situations in the light of circumstances. Perhaps this is even a case of over-training whereby individual officers perceive dynamic assessment as only suitable for major incidents - or is it that the rules are so written as to proscribe the use of intellectual judgement.

Dynamic assessment to be truly effective has to be used at the time of performing ALL tasks, minor or major, in order to bring the person into the assessment process and ownership of their own actions.

Sorry if it looks like I've hi-jacked your post Martin.

Ken, A very valid point that you raised; I wasn't targetting your earlier comment as such; simply reinforcing the concept that the Police have direct responsibility rather than any other body in such circumstances 'cos the FS appeared to be presented as the prime culprits in the original post.

Robert K; I accept your observations, but the real point of my drearying on earlier was to identify that the FS [the actual firefighters who committed the alleged mayhem] are not, and don't pretend to be, experts in deciding how dangerous any substance or substances are; nor how to make them safe. They rely very heavily on information and guidance that is essentially external to the FS and certainly not within the control of those being directed at the scene.

So, for me, the real issue is that one aspect of Roberts response is very true - that the FS have only a restricted and generally inflexible range of responses at such an incident.

What the FS reely, reely needs is for a demonstrable and consitantly high calibre of practical & competent guidance and advice to be provided to those who are pilloried for being such enthusiastic vandals in the protection of the public. Personally, I have, in the past, spent several hours at incidents where I have suspected [only suspected 'cos I'm not competent in the chemical field] that there could have been far less public expenditure involved.

Oh yeah, knew there was something else that I wanted to say - there is no actual legislative requirement for the FS to have done anything!!! This was obviously an "operational decision" that several people in higher FS places are now distancing themselves from as quickly as possible.

Nighty night - don't spill anything that you can't pick up [or hide].

I know this has gone a bit off topic, but there are regular criticisms of the police for closing roads for too long after a major RTA, but it must be remembered that it is a potential crime scene.

If a person has died, or is considered likely to die, or has serious injuries, the same investigation will go on as if it was a murder scene.

You cannot preserve or find evidence with traffic driving over or near the scene. A finger tip search may be necessary to identify minute markings on the road, or to find a small piece of a vehicle that may have come lose or caused the incident.

It is not unknown for vehicles to be used as weapons, so the police must assume the worst until all avenues have been investiagted.

I get frustrated like you, but I am sure I would want a proper investigation if one of my loved ones was involved.

Would you object to a factory being closed down whilst a HSE Inspector thoroughly investigated a death or serious injury ?

Whilst understanding the need to investigate, this should not be at the risk of many other lives, preventing doctors, ambulance crews, firefighters, etc from doing there work properly and at considerable cost to the community. Common sense is needed to consider the overall situation and not just the need for possible evidence. At times there are more important matters to be taken into account (risk assessment!).

Another aspect of relying upon the guidance of persons not present is the need for accurate information on the whole situation including the consequences of actions and inaction. Experts tend to look at their own fields of expertise whereas good local management should see the overall picture.

From one of my earlier existences, I can recall being called to a collapsed footbridge only to find it was some steps to the front door of a house above a basement entrance and also a suggestion that it might be worth checking the condition of a scaffold which turned out to be a massive structure leaning over a major 'A' road and at risk of collapse!

I have just had to pick up my operational fire fighting colleagues from the floor (after having carried out the relevant risk assesment of course) after retelling this tale. Obviously over zealous - glad it wasn't in my brigade...!!!

Could this be an urban legend though? I have searched high and low, including the BBC local news, and can find no mention of it. Not a sausage - even in local news sites. Just curious, as I would like more details in case we get called to a similar incident.

If true, the response was OTT in my opinion as a qualified chemist and safety professional. I have many years experience dealing with mercury spills and broken mercury thermometers in University chemistry laboratories.

The incident could have easily dealt with and cleared up: even without the employment of sulphur or a paste of calcium hydroxide and sulphur. Sulphur (or paste mix) is applied to lower the vapour pressure.

The amount of mercury in a clinical thermometer is small and breakages in my experience tend to involve a break in the glass tube and not the bulb resulting is a very small release of mercury. The kitchen floor could carefully be swept and the mercury gathered: it will coalesce. Ideally, a pipette type suction device should have been employed to 'suck up' the mercury and transfer it to a suitable container (small tupperware comes to mind). Absorbent sponge type spillage kits are now availabe on the market (Fischer) and the appilication here would have been equally as effective.

In the short term (i.e. accute effects) elemental mercury does not pose a threat to human health: uptake of mercury (vapour) by inhalation is easily passed through body and excreated. The long term effects of mercury are well known : it is chronic poison.

As to the advice provided to the emergency services: incorrect and the "chemist" better hope they have good PI.

Ah, yes, that wonderful silvery stuff. From the waste disposal point of view, we have in the pass, recommended to people to wear a mercury filtered facemask (ABEK1-Hg from memory) and waterproof clothing and gloves.

Based on the extremely short exposure time in cleaning the stuff up, mercury can be collecetd in blotting paper or at least moved to a suitable absorbent rag. This can then be put into a suitable glass container with thermometer for labelling and disposal by the authorities.

From experience, how many knowledgable and untrained people dispose of these wonderful devices via their municipal waste collections, hidden in the 'bins'. If soneone can confirm by checking environmental sites on the web, i remember from memory, that a amount of thermometer mercury can pollute and contaminate a loch (sorry 'lake/pond' of water)which would only affect the fish (being poached), plantlife, domestic drinking supply if drawn from it.

Anyway, now that the incident has passed, would the general public of learned from the incident based on how the article would of been accurately and objectively been printed by the media.

Right, back to earning some serious money now!
