Product,Application & Engineering FAQ,Commercial FAQ

Emergency eyewash and safety shower stations should be installed wherever employees may be exposed to hazardous chemicals, corrosive substances, harmful dust, airborne particles, biological contaminants, or other materials that could injure the eyes or skin.

Typical industries include chemical processing, oil & gas, mining, pharmaceuticals, laboratories, manufacturing, food processing, wastewater treatment, construction, utilities, and educational or research facilities.

Common installation locations include:

• Chemical storage and dispensing areas
• Laboratories and testing rooms
• Battery charging stations
• Paint and coating areas
• Welding and grinding workshops
• Machine and maintenance shops
• Fuel storage areas
• Wastewater treatment facilities
• Production lines
• Boiler rooms
• Pharmaceutical and healthcare departments
• Loading docks and material handling areas

Emergency equipment should be installed as close as practical to the hazard, with an unobstructed path for immediate access.

The correct equipment depends on the type of hazard, installation environment, and applicable safety standards.

Typical selection considerations include:

• Eyewash only or combination shower and eyewash
• Indoor or outdoor installation
• Temperate, tropical, or freezing environments
• Hazardous (Ex) or non-hazardous locations
• Water supply pressure and flow rate
• Material requirements such as SUS304, SUS316L, or corrosion-resistant finishes
• Optional features including alarms, lighting, foot pedals, drain systems, and heated or insulated enclosures

If you are unsure which model is appropriate, DAAO can recommend a solution based on your project specifications and site conditions.

ANSI Z358.1 specifies the minimum performance and installation requirements for emergency eyewash and shower equipment.

Key requirements include:

• Equipment should be reachable within approximately 10 seconds of the hazard.
• The access path must remain clear and unobstructed.
• The equipment must activate quickly and remain hands-free once operated.
• Water should be delivered continuously for at least 15 minutes.
• Equipment should be tested and maintained regularly to ensure reliable operation.

Always verify local regulations and project specifications in addition to ANSI requirements.

When selecting an emergency eyewash or safety shower system, the choice between plumbed and portable equipment depends on your workplace conditions, hazard locations, and facility requirements.

Portable Eyewash System
A portable eyewash system is designed for workplaces where permanent plumbing connections are unavailable or where hazard locations may change frequently.

Advantages of portable units include:

• Flexible installation: No permanent water supply connection is required.
• Easy relocation: The unit can be moved when work areas or hazard locations change.
• Multiple configurations available: Pressurized portable units provide flexibility for remote sites; gravity-fed units are lightweight and suitable for locations where mobility is required.

Portable eyewash stations can be installed in different ways depending on the model:

• Wall-mounted installation
• Mobile cart-mounted installation
• Bench-top installation

Maintenance requirements: Units must be maintained with appropriate bacteriostatic treatment to prevent bacterial growth. The flushing fluid should be replaced according to manufacturer instructions to ensure safe and effective flushing.

Plumbed Emergency Eyewash System
A plumbed system is permanently connected to a facility’s water supply and is typically used as a fixed safety installation in industrial environments.

Advantages include:

• Reliable water supply: Connected directly to the building’s plumbing system.
• Suitable for permanent hazardous locations: Ideal for manufacturing plants, laboratories, chemical processing facilities, and industrial sites.
• Various installation options: Available in configurations including wall-mounted, pedestal-mounted, floor-mounted, faucet-mounted, and deck-mounted units.

According to ANSI/ISEA Z358.1, emergency eyewash and shower equipment should be designed with stay-open valves, allowing the unit to continue supplying flushing fluid without continuous manual operation.

The selection depends mainly on your application:

For permanent industrial installations, a plumbed emergency shower and eyewash system is usually the preferred solution due to its continuous water supply and lower maintenance requirements. Portable units are a practical alternative where plumbing connections are not feasible.

Yes. DAAO provides customized solutions for industrial projects worldwide.

DAAO offers emergency shower and eyewash systems manufactured from materials suitable for different industrial environments, including:

• Stainless Steel 304 (SUS304)
• Stainless Steel 316L (SUS316L)
• Galvanized carbon steel (available for selected applications)
• ABS or corrosion-resistant components where appropriate

Material selection depends on factors such as corrosion resistance, chemical compatibility, environmental conditions, and project specifications.

Emergency eyewash and shower equipment should be inspected and tested regularly to ensure proper operation.

Typical maintenance includes:

• Weekly activation checks to verify water flow and flush stagnant water.
• Periodic inspections for leaks, corrosion, damaged components, and accessibility.
• Preventive maintenance according to ANSI Z358.1, local regulations, and the facility’s safety procedures.

A documented inspection program helps ensure the equipment is ready for use whenever an emergency occurs.
