Pressurized eye washes are essential safety devices in industrial environments where access to running water may be limited. These portable and self-contained units are designed to provide a rapid and effective response in the event of exposure to chemicals or hazardous materials that can affect the eyes or skin.

What is a pressurized eye wash and what is it used for?

Let's start with the basics. A pressurized eye wash is a portable system that contains water or saline solution stored under pressure. The term "pressurized" means that the liquid is maintained under a controlled pressure to ensure a constant and adequate flow when needed. These devices are crucial for:

• Providing immediate irrigation in the event of chemical splashes.
• Offering first aid treatment in areas without access to running water.
• Complying with workplace safety regulations in high-risk industries.

Key features of pressurized eye washes

• Tanks with a capacity of up to 21 gallons (79.49 liters).
• Maximum working pressure of 130 psi (896.3 kPa).
• Relief valve that activates at 115 psi (792.9 kPa).
• Portable design for easy location in critical areas.
• Some models include a thermal jacket to maintain water temperature between 60°F and 90°F (15°C and 32°C).

How often should eye wash stations be cleaned?

Regular cleaning and maintenance are essential to ensure the effectiveness of pressurized eye washes. It is recommended:

• Daily visual inspection.
• Weekly cleaning of the head and nozzles.
• Draining, cleaning, and refilling the tank every 3-6 months, depending on the work environment.

What liquid is used in eye washes?

The liquid used in pressurized eye washes is typically:

• Clean drinking water.
• Sterile saline solution.
• Specialized solutions for eye washing, depending on the specific hazards of the workplace.

It is essential that the liquid is kept clean and changed regularly to prevent bacterial growth.

Where should eye washes be located?

The location of pressurized eye washes is critical for their effectiveness:

• They should be within 10 seconds of areas with hazards.
• Place them on evacuation routes and near emergency exits.
• Ensure they are visible and easily accessible, without obstructions.
• In areas where running water is not available or as a supplement to fixed stations.

What is pressurization in the context of eye washes?

Pressurization means maintaining the liquid inside the tank under a controlled pressure to ensure a constant and adequate flow when the device is activated.

How does a pressurized eye wash work?

A pressurized eye wash uses the stored pressure in the tank to expel the liquid when the valve is activated. This ensures an immediate and constant flow without the need for manual pumping.

Why choose a pressurized eye wash over a non-pressurized one?

Pressurized eye washes offer a faster response and a more consistent flow, which is crucial in emergency situations where every second counts.
