Facing hazards in the food industry
21 June 2022
THE FOOD and drink industry is the largest manufacturing sector in the UK, with a total turnover of £112b in 2021. For a hygienic and sterile environment, it’s important that all safety showers inside a food and drink facility are made of stainless-steel. This ensures the showers are durable, corrosion resistant and easy to clean.
Both the EN 15154 and the internationally recognised American National Standard, ANSI/ISEA Z358.1-2014 provide uniform minimum requirements for the performance, use, installation, testing, maintenance and training of emergency safety shower and eyewash equipment. Here we outline some of the main considerations.
In order to minimise any injury with a swift decontamination in the event of a spill or splash, emergency safety showers must be located within 20 metres, or 10 seconds reach, of a hazard. However, if a chemical is particularly hazardous, the safety shower and/or eye/face wash equipment must be placed immediately adjacent to the hazard. Personnel should be instructed on the safe and proper use of the emergency safety equipment and be advised of its location.
Emergency safety equipment must be visually inspected and activated weekly along with an annual service to guarantee reliable and effective operation and conformance to European and International standards.
According to these standards, the water delivered by emergency safety showers should be tepid, between 15-37 C (59-98.6 F). At temperatures above 37 C (98.6 F) there is the added danger of scalding and increased absorption of harmful chemicals into the skin whereas prolonged exposure to water below 15 C (59 F) increases the risk of thermal shock or hypothermia and prevents the casualty using the shower to decontaminate effectively for the full 15 minutes.
Some chemicals dictate a particular decontamination procedure. For example, contact with anhydrous ammonia requires flushing of the area with a large amount of water for at least 15 minutes, at a temperature between 25C-30C. For set temperature decontamination, you will need a Temperature Controlled Safety Shower. These units maintain the water within a set range and can also be used to supply heated water to other emergency safety showers in the local vicinity. Always check the safety data sheet of the hazardous material for specific decontamination requirements.
In manufacturing, space is at a premium. Over-door, ceiling and wall-mounted models are an easy solution to ensure as little floor space as possible is used. Where there is a little more space to spare, combination units comprise of a plumbed in safety shower as well as an eye/face wash for full decontamination.
In some instances, the spray and contaminated water will need to be carefully contained to ensure a sterile environment, cubicle units are the ideal solution as they are enclosed with an integral drain sump.
The food and drink industries are varied and complex with many potential health and safety risks. It is imperative that workers who are exposed to hazardous substances have easy and quick access to safety showers and eye/face wash equipment in the event of a spill or splash.
