The emergency showers and eye washes are essential devices in any industrial environment where hazardous substances are handled. However, their mere presence is not sufficient; regular maintenance is essential to ensure optimal functioning when it is most needed.

In this article, we will explore the best practices for maintaining these safety equipment in perfect condition.

Recommended frequency of inspection and cleaning

Regular inspection and cleaning of emergency showers and eye washes are not only a good practice, but also a legal requirement in many countries. According to international standards, such as ANSI Z358.1, it is recommended:

  • Daily visual inspection : Verify that the equipment is accessible, free of obstacles, and without visible damage.
  • Weekly activation : Run water for several minutes to ensure adequate flow and eliminate stagnant water.
  • Monthly inspection : Examine the equipment's function, water pressure, and overall condition in more detail.
  • Annual maintenance : Perform an exhaustive inspection, including deep cleaning and replacement of worn-out parts.

Appropriate cleaning products

The choice of appropriate cleaning products is crucial to maintain the integrity of the equipment without compromising its function:

  • Mild detergents : Use non-abrasive and biodegradable soaps for general cleaning.
  • Approved disinfectants : Use disinfectants that do not leave toxic residues.
  • Antiscalant products : In areas with hard water, use mild antiscalant products to prevent mineral buildup.
  • Avoid abrasive products : Do not use cleaners that may damage surfaces or contaminate the water supply.

Basic maintenance procedures

Regular maintenance can be performed by following these steps:

  • Exterior cleaning : Clean all visible surfaces with a damp cloth and mild detergent.
  • Bores inspection : Verify that the bores of the eye washes are clean and free of obstacles.
  • Valve inspection : Verify that the valves open and close properly.
  • Tube and connection inspection : Look for signs of fatigue, leaks, or damage in all connections.
  • Flow test : Measure the water flow to ensure it meets the required standards.
  • Drainage inspection : Verify that the drainage system functions correctly to prevent flooding.

Alert signals indicating the need for inspection

It is important to remain vigilant for the following signals that may indicate problems with the equipment:

  • Irregular or weak water flow : May indicate obstacles or pressure problems.
  • Changes in water quality : Turbid or foul-smelling water may indicate contamination of the system.
  • Unusual noises : Silences or knocks when activating the equipment may indicate problems with valves or tubes.
  • Visible corrosion : Signal that some parts may need to be replaced.
  • Difficulty activating : Valves that do not open easily require immediate attention.
  • Leaks : Any leak, no matter how small, must be addressed promptly.

The importance of documentation

Keeping a detailed record of all inspections, cleanings, and maintenance performed is essential. This documentation not only helps to follow a consistent maintenance program, but it may also be vital in the event of a safety audit or incident investigation.
