Posted By clare coles Hi I wonder if someone can help me? At my husband's workplace there is a kitchen for staff to use to eat their meals etc. The taps are separate (ie hot and cold) and have signs displaying this. One of his members of staff scalded their hand on the hot tap yesterday and said that the taps are WRONG and they should be MIXER taps!! Does anyone know any legislation supporting this? Any help would be great, thanks Clare

Posted By MT There isn't any legislation to support changing single taps to a mixer tap. However, if the water is being kept hot enough that people are being scalded, then this would need to be taken into account. The company may want to consider a mixer tap or a thermostatic control valve on the tap to lower the water temperature.

Posted By clare coles MT Many thanks for your reply. The water apparently has checks to make sure temperature does not exceed safety levels etc, I just wanted to know if there was legislation as this person was adament that there was????

Posted By MAK Ask the person to name the legislation paragraph and verse! I, agree with MT, have not heard of any legislation stating mixer taps are a must. However, the employer does have duties under Part 1 of the Health and Safety at Work Act 1974 to provide and maintain plant and systems that "so far as reasonably practicable" without risks to safety and health. etc If there is a risk from scalding or any other injury, then the H&S rep/manager/facilities management rep should be notifed and the situation assessed appropriately. Obviously the system currently in place is not without risk.

Posted By J Knight Hi Clare, the only legislation would be the Care Standards Regulations (England and Wales) and they would apply to Registered Care Homes, Independent Hospitals and the like (NHS is also strictly regulated by HSE on this but I think just under MHSW Regs). In these premises the law doesn't actually require any particular kind of tap, rather it sets very strict limits on the permitted maximum temperature, and even then only in areas where service users/patients would be at risk. Not in staff rooms. So if its not care premises there is no law, and even there it doesn't have to be mixer taps, even in care areas, John

Posted By holmezy Clare, there are regulations ie HASAW reg 3 Ensure the safety etc of employees, so it is covered, but in a general sense. There is no specific regs regarding taps, although your water should not be greater temp than 63 degrees(ish) as I recall. Mixer taps wont stop people getting scalded, especially if the tap is in the "hot" position but fitting thermostatic mixer valves in the pipeline will limit the temeperature to about 45 degrees(ish). As far as I can remember, the temperature of 60 ish degrees is required to ensure your stored water is relatively bug free ie legionella etc.

Posted By Merv Newman "scalding" means blistering. At least. Hot water systems, as Holmzey says, run at 60 to 63 °C Directly holding your hands into a 63° stream might cause some temporary pain and erythema but few people will maintain their hands in the stream long enough to produce blistering. Unless they are into the "self-harm" mode. I would suggest that the phrase "that hurt" rather than "that scalded" is more correct. And who doesn't know how mixer taps work ? Gawd. Merv

Posted By mike morland Clare Our office kitchen has mixer taps but they will not prevent the risk of being scolded. However I would offer the following: - The water should be heated to 60 degrees in the first instance as the Legionella bacteria will not survive at this temperature. Secondly, there is the requirement to assess the likelihood of scolding and reduce or eliminate the risk where reasonably practicable. If this can't be done by fitting some kind of a heat reducing filter between the storage tank and the outlet then perhaps suitable warning signage along the lines of 'CAUTION VERY HOT WATER, RISK OF SCALDING' along with advice such as - 'Enter cold water into the sink first then add the hot water until the required temperature is achieved'. This is the precaution that we have taken in respect of all hot water outlets. Regards

Posted By peter gotch Hi Clare There are various U.K. standards for maximum water [and, in some cases associated metal work] temperatures in bathing environments, which take account of research into the relationship between water temperature and the exposure time associated with severe burns. Various of these standards are referenced in Building Research Establishment [BRE] Information Paper IP14/03 “Preventing hot water scalding in bathrooms : using TMVs”. NHS Estates Health Guidance Note “Safe hot water and surface temperatures” gives guidance on maximum point of delivery water temperatures for a range of applications. These are set out below. MAXIMUM SET HOT WATER TEMPERATURES Application Maximum temperature oC Bidet 38.00 Shower 41.00 Washbasin 41* Bath 44.00 Bath 46* Notes * For washbasins, washing under running water is assumed ** Bath fill temperatures of more than 44oC should only be considered in exceptional circumstances where there are particular difficulties in achieving an adequate bathing temperature. If a temperature of more than 44oC is to be used then a safe means of preventing access to the hot water should be devised to protect vulnerable patients. Standard practice in procurement within the NHS and e.g. care setting environments is to specify a maximum point of delivery water temperature of 43oC, and a similar maximum temperature for accessible associated metalwork, e.g. radiators. At paragraph 20 of Local Authority Circular [LAU] 79/5 at www.hse.govluk/lau/lacs/79-5.htm, the Health & Safety Executive [HSE] comment that it was consulted as to whether 43oC should be retained as the limit in NHS Estates and other guidance. They add that “However, no convincing evidence of a significant increased risk, at the higher temperature of 44oC, could be found. BRE note the findings of research into injuries associated with exposure to hot water: “Severe scalds in seconds The degree of scalding depends on the temperature and volume of hot water, and the length of time the body is exposed to it. However, it can take only seconds for a severe scald to occur. Research (Waller et al, 1993) indicates that: As the temperature of the water increases above 50°C, the duration of exposure needed to suffer third-degree burns decreases rapidly. Healthy adult skin requires 30 seconds of exposure to water at 54°C – 55°C before third-degreeburning occurs, but only 5 seconds at 60°C and less than one second at 70°C. However, the skin of children and the elderly is even more sensitive to extreme temperatures.” Regards, Peter

Posted By Lee Mac There is no legislation which dictates that mixer taps should/shouldn't be used. I appreciate that a burn from a hot water tap can be quite nasty, toes & bath taps don't mix, cmon we all have done it, but we lived to see another day. It is down to a bit of common sense. Clarkeson will have a field day with this one!!!

Posted By Chris Packham There is evidence that washing hands in hot water significantly degrades the skin's barrier properties. It can take one or two hours for these to return to normal. The ideal temperature for hand washing is between 32 and 38 deg. C. Obviously you cannot pipe water around the system at this temperature, nor can you rely upon the individual to set the water temperature correctly. We ran an experiment with occupational physicians on this and they all thought they had set the temperature to the correct level, whereas the thermometer showed it to be in excess of 40 deg. C, i.e. with a potential to damage the skin barrier. Thus the only really satisfactory method is a single tap (possibly infra-red operated) with a preset mixer valve located immediately before the tap. Chris
