With winter looming if you haven't yet done so it is a vital time to conduct an annual service, inspection and compliance assessment for every on-site safety shower, eyewash station and also, just as importantly, the supply pipe. Ensuring that your emergency showers and eyebaths are fit for purpose and ready to withstand the winter freeze is essential in order to avoid further problems that may occur when the temperature drops.
When it comes to the safety of personnel, just installing a piece of safety equipment is not enough. Testing for uninterrupted operation and functionality of both internal and external safety showers is vital. Not doing so can put workers lives in danger.
These critical pieces of health and safety equipment very often slip through the regular maintenance duties on site. During periods of cold weather this can leave the equipment non operable and liable to long term damage. A planned Winterisation programme that includes annual servicing will prevent downtime and costly repair bills and will also provide peace of mind that the showers and eyebaths will operate perfectly when needed.
Such a plan should include a full report that records the operation, testing and servicing of showers in accordance with the relevant standards including ANSI Z358.1-2009** and BS EN 15154 covering key points, for example shower flow rates, water temperatures and location. This is important with the ever increasing demands of international standards and health and safety requirements which state maintenance and test regimes must be kept.
There is a requirement to ensure that safety eyewashes and showers supply clean, potable water and are in proper working order. So you need to ensure that the water flow is continuous; evaluate that the unit can maintain flow for 15 minutes, and is not injurious to the user's eye or face. Valve actuators must activate water flow in one second or less and controlled flow of flushing fluid must be provided to both eyes simultaneously.
With the changing climate, exposed pipe work that would have normally survived the winter is no longer adequate and will not meet the recommended standards. This will mean either re-siting the shower unit or freeze protecting the pipework.
In house inspection programmes should necessitate updating your risk assessments. This should include assessing not only against the control of substances hazardous to health (COSHH) but also against climatic conditions, the surrounding environment and the workforce including lone workers and the mix of male/female operatives for example. If processes and site layouts change operationally you need to carefully reconsider the type of decontamination solution that meet the needs of the workers and environment in which they work.
To make sure casualties can use the shower for the recommended 15 minutes minimum (to ensure chemicals are thoroughly washed off) the water must be of a tepid temperature as cold water directly from the mains will cause casualties to stop using the shower too soon due to thermal shock.
And talking about your operatives, hopefully they have never had to use the safety shower but can they remember where the emergency facilities are located? For example, if working near hazardous substances, it can be time critical that they are aware that a facility is available in the direct vicinity rather than having to get to a main building which could be driving distance away. This also reduces any further spread of the contamination.
Emergency eyewash and shower unit facilities must be installed in work areas where there is high potential for accidents involving corrosive, irritant or toxic substance absorption through skin and eyes. The location should be no more than a maximum of 10 seconds travel time for an injured person to access as every second counts. Therefore, there should be nothing to obstruct the pathways leading up to an emergency shower or items stored on top of an eyewash sink. Ensure that the pathway is well lit and all directional signage is still in place and clearly visible.
Operatives also need to be fully briefed on the potential danger of the hazards within which they are working, they also need to be trained on how to operate the shower and also key items that should be checked routinely that might prevent correct operation. Waste-water treatment workers, for example, are in close contact with sewage, storm water and treatment chemicals. The hazards are therefore high. Workers need to know and understand exposure limits and what to do when it comes to decontaminating clothing and the body.
So, there are a number of steps you can take to ensure your emergency facilities are fit for purpose but most importantly you must make clear who is responsible for carrying out inspection, weekly testing, recording and maintenance. If there is anything wrong with the facility there must be a tagging process put in place whereby workers themselves can check that an emergency shower has been properly tested and report anything they believe to be unsafe.
** ANSI Z358.1 2009
Ensure continuous water supply delivering 76 litres of per minute for 15 minutes.
Deliver Tepid Water (16 Deg C – 38 Deg C), to prevent thermal shock and ensure casualties can use the shower for the full duration.
Installed so the shower head is between 208 – 244cm from the floor.
Safety Showers must be located within 10 seconds/15 metres of a potential hazard.
Safety Showers must be located on the same level as the hazard and the path should be free of obstructions. Any doors that have to be negotiated must not have a lock and must open in the direction of travel towards the shower.
The unit should be well lit and identified with a highly visible sign.
All units to be activated weekly to flush the line and verify proper operation and ensure flushing fluid is available.
All units must be inspected annually to assure conformance to above standard.
Stay-open valve (hands-free) activates in one second or less.
Eye wash heads positioned between 84-114cm from the floor.
Combination unit components shall be positioned so that the components may be used simultaneously by the same user.
All employees who may be subject to exposure to hazardous materials must be trained in the use and also the locations of the unit.[Go Back]
