10 SO HAVE YOU COMPLETED YOUR RISK ASSESSMENT?

11 WHAT HAZARDS SHOULD OUR RISK ASSESSMENT COVER Drowning Legionella Manual Handling Microbiological Risks Chemical Safety Electrical Safety Safe Storage of displays

12 SAFE DISPLAYS

13 ELECTRICAL SAFETY - HEALTH AND SAFETY EXECUTIVE/LOCAL AUTHORITIES ENFORCEMENT LIAISON COMMITTEE - SAFETY IN ELECTRICAL DISPLAYS Competence of staff Display layout It is strongly recommended that the electrical wiring to the display should be installed fully in accordance with BS 7671 Requirements for Electrical Installations (also known as the IEE Wiring Regulations). In addition it is recommended that, wherever practicable, the display is additionally protected by means of a Residual Current Device (RCD) suitable for protection against electric shock. Suitable types are often known as "30mA/30mS" devices.

14 ELECTRICAL SAFETY - HEALTH AND SAFETY EXECUTIVE/LOCAL AUTHORITIES ENFORCEMENT LIAISON COMMITTEE - SAFETY IN ELECTRICAL DISPLAYS Maintenance All display installations should be visually inspected at regular intervals to determine whether deterioration and/or damage has occurred. The periods between such inspections will depend on the use/abuse of the systems. Publication INDG236 Maintaining portable electrical equipment in low risk environments should be consulted to determine an appropriate initial frequency of visual inspection and how to determine inspection frequencies thereafter. It is recommended that the premises' electrical installation should be subject to an annual routine check and a formal inspection on a 5- yearly basis by a suitably competent person to ensure it remains in a safe condition.

15 MICROBIOLOGICAL CONDITIONS (ECOLI, PSEUDOMONAS, ETC) Should not be an issue unless you are going to permit bathers in to your spa / hot tubs. If you are going to enter the water then have you set safe parameters for; Free chlorine Combined chlorine ph What is your frequency of your testing regime? What training has your member of staff received to demonstrate competence? Have you recorded the results?

16 LEGIONELLA What is legionella? Is there a risk with a spa / hot tub? Is there guidance for us to follow? What should we be doing?

17 WHAT IS LEGIONELLOSIS Legionellosis is the collective name given to the pneumonia-like illness caused by legionella bacteria. This includes the most serious legionnaires disease, as well as the similar but less serious conditions of Pontiac fever and Lochgoilhead fever. Legionnaires disease is a potentially fatal form of pneumonia and everyone is susceptible to infection. However, some people are at higher risk, including: people over 45 years of age smokers and heavy drinkers people suffering from chronic respiratory or kidney disease anyone with an impaired immune system

18 SYMPTOMS OF LEGIONELLA The symptoms are similar to those of flu, i.e. high temperature, fever and chills, cough, muscle pains and headache. In a severe case, there may also be pneumonia, and occasionally diarrhoea, as well as signs of mental confusion. Legionnaires disease is not known to spread from person to person.

19 WHERE DOES IT COME FROM Legionella bacteria are widespread in natural water systems, e.g. rivers and ponds. However, the conditions are rarely right for people to catch the disease from these sources. Outbreaks of the illness occur from exposure to legionella growing in purpose-built systems where water is maintained at a temperature high enough to encourage growth, e.g. cooling towers, evaporative condensers, spa pools, and hot water systems used in all sorts of premises

20 HOW DO PEOPLE CONTRACT IT People can catch legionnaires disease by inhaling small droplets of water, suspended in the air, containing the bacteria. Certain conditions increase the risk from legionella, including: water temperature between C, which is suitable for growth creating and spreading breathable droplets of water, e.g. aerosol created by a cooling tower, or water outlets stored and/or re-circulated water a source of nutrients for the organism e.g. presence of sludge, scale or fouling

21 IS THERE A RISK FROM SPAS

22 IN 1999, AN OUTBREAK OF LEGIONNAIRES' DISEASE AFFECTED MANY VISITORS TO A FLOWER SHOW IN THE NETHERLANDS. From March 7 to 11, 1999, 10 patients with severe pneumonia were admitted to a hospital in Hoorn, in the northern part of the Netherlands. The clinical condition of these patients deteriorated quickly and unexpectedly, with eight requiring mechanical ventilation. On March 11, six patients were diagnosed with Legionnaires' disease on the basis of a positive Legionella urine antigen test. Additional patients with severe pneumonia were sent to another hospital since all the respirators at the Hoorn hospital were in use All patients had visited the West Frisian Flower Show Dates of onset ranged from February 25 to March 16

23 IN 1999, AN OUTBREAK OF LEGIONNAIRES' DISEASE AFFECTED MANY VISITORS TO A FLOWER SHOW IN THE NETHERLANDS. There were 188(133 laboratory confirmed) cases and 21 deaths. People pausing at the spa pools had an increased chance of developing the disease. Within four days of their installation one or both of two new spa pools on display at a Netherlands flower show were the source of one of the worlds largest outbreaks of Legionnaires disease.

24 IN 1999, AN OUTBREAK OF LEGIONNAIRES' DISEASE AFFECTED MANY VISITORS TO A FLOWER SHOW IN THE NETHERLANDS. Findings Data demonstrated that contaminated spas may remain culture positive for months, perhaps as a result of stagnant water in their extensive inner tubing system. Because Legionella is ubiquitous in water systems, prevention of Legionnaires' disease depends mainly on disinfection. The findings showed that whirlpool spas may become a health hazard if their disinfection system fails.

25 IN 1999, AN OUTBREAK OF LEGIONNAIRES' DISEASE AFFECTED MANY VISITORS TO A FLOWER SHOW IN THE NETHERLANDS. Bathing in whirlpool spas has led mainly to outbreaks of Pontiac fever and to lesser extent Legionnaires' disease. Data showed that even staying in the vicinity of a whirlpool spa or walking in a hall where an operating whirlpool spa is on display may be important risk factors for Legionnaires' disease. Considering the popularity of whirlpool spas at home and the number of exhibitions where they are displayed, we suspect that small outbreaks have occurred without detection. None of these devices were maintained with adequate disinfection. The whirlpool in hall 3 had never been used before, and its disinfection system failed.

26 AGAIN IN 1999 Outbreak of Legionnaire's disease at Kapellen in Belgium among visitors of the annual fair. 93 cases and 5 deaths. Those individuals working in the central areas of the tent, near the aerosol-producing devices, were at higher risk of disease. Legionella was detected on swabs of the surfaces of the whirlpool. Although not fully proven, an aerosol-producing device was the most probable source of the outbreak.

27 SO WHAT GUIDANCE SHOULD WE BE FOLLOWING No primary legislation is currently in place to manage spas and hot tubs in display settings. No primary legislation for that matter covering spas and hot tubs in operation in commercial settings So what help is there?

28 WE NEED TO RELY ON ASSOCIATED REGULATIONS AND GUIDANCE

29 SO WHAT GUIDANCE SHOULD WE BE FOLLOWING HSE reviewed its ACOP and guidance for legionella in 2013 New ACOP L8 The main changes are removing Part 2, the technical guidance, which is published separately in HSG274,

30 SO WHAT GUIDANCE SHOULD WE BE FOLLOWING Undertake risk assessment by a competent person Microbiological testing monthly (if used by bathers) Levels for Chlorine & ph Quarterly sample for legionella

31 SO WHAT GUIDANCE SHOULD WE BE FOLLOWING Undertake risk assessment by a competent person How complicated our your spas and hot tubs? Are you competent?

32

33 COULD IT HAPPEN TO THOSE DISPLAYING SPAS IN THE UK We have historical evidence from Europe that it can occur with equipment similar to that on display in our outlets The industry has been given sufficient guidance from the HSE & HPA Can there be any excuses for an outbreak in the UK?

34 WHAT DID WE LEARN FROM 2008 Note that no evidence any person suffered harm The mere fact that you put people at risk by your failings can be sufficient grounds for prosecution

35 JTF STOKE ON TRENT

36 JTF STAFFORDSHIRE CASES & 3 DEATHS

37

38 POSSIBLE LEGAL CONSEQUENCES OF THIS TYPE OF CASE If its your business Corporate Manslaughter If its you personally gross negligence manslaughter General health & safety breaches

39

40 JTF Case MANSLAUGHTER charges may be brought against a company after three men died in an outbreak died of legionnaire s disease in Stokeon-Trent. Richard Griffin, of Westbury Park, 79-year-old William Hammersley, of Chesterton and Harry Cadman, aged 71, of Stoke-on-Trent, all died after being struck down with the disease which was linked to Fenton discount warehouse JTF. A further 18 people needed hospital treatment following the outbreak of summer 2012 Now evidence gathered by Stoke-on-Trent City Council for a health and safety prosecution against the company has been passed onto Staffordshire Police.

41 FINALLY DISINFECTION LEVELS Arguably the levels could may be kept lower if bathers not present but the general parameters for display spas should be; Chlorine 2mg/l 4mg/l Bromine 4mg/l 6mg/l ph Requires regular monitor to ensure disinfection present and the system is working. Results of the tests recorded
