Emergency Shower and Eyewash Station Requirements
0 2020-04-16

ANSI/ISEA Z358.1 is an international consensus standard that helps users select, install, operate, and maintain emergency eyewash, eye/face wash, and shower equipment. It was issued in 1981 and revised in 1990, 1998, 2004, 2009, and again in 2014.

 

Installation / Location:

 

Must be accessible within 10-seconds of hazard, approximately 55-feet (consult a medical professional to determine the appropriate distance for harsh acids and caustics; high hazard = closer distance)

Must be located on the same level as the hazard

Path of travel must be free of obstructions—Appendix B5 clarifies that a step into an enclosure where emergency equipment is located is not considered an obstruction

The location must be well lit and identified with a highly visible sign

If shut-off valves are installed in the supply line for maintenance purposes, provisions must be made to prevent unauthorized shut-off

 

Temperature

 

Must deliver tepid flushing fluid—suggested temperature range of 60–100°F

Maintenance and Inspection

 

Activate plumbed units at least weekly to verify proper operation

Visually check self-contained units weekly to determine if flushing fluid needs to be changed or supplemented

Inspect annually for compliance with ANSI/ISEA Z358.1 performance requirements

Training

 

Instruct all employees in the location and proper use

Shower Requirements

There are two types of emergency showers:

 

Plumbed Shower: An emergency shower permanently connected to a continual source of potable water

Self-Contained Shower: A stand-alone shower that contains its own flushing fluid

 

Shower Requirements

There are two types of emergency showers:

 

Plumbed Shower: An emergency shower permanently connected to a continual source of potable water

Self-Contained Shower: A stand-alone shower that contains its own flushing fluid

Key emergency shower features and specifications include:

 

The hands-free valve activates in one second or less and remains open until manually closed

The plumbed unit delivers 20 gallons of water per minute for 15 minutes at 30 pounds per square inch pressure in the required pattern

The self-contained unit delivers 20 gallons of water per minute for 15 minutes in the required pattern

The height of the water column is between 82 and 96-inches above the surface on which the user stands

At 60 inches above the surface on which the user stands, the water pattern is at least 20 inches in diameter

The Center of the water pattern is at least 16 inches from any obstruction

Easily located, the accessible actuator is no more than 69 inches above the surface on which the user stands

If provided, the shower enclosure has a minimum diameter of 34 inches

 

Eyewash and Eye/Face Wash Station Requirements

There are two types of eyewash and eye/face wash stations:

 

Plumbed station: An eyewash unit permanently connected to a continual source of potable water

Gravity-fed (self-contained) station: A stand-alone eyewash device that contains its own flushing fluid that must be refilled or replaced after use

Key eyewash and eye/face wash station features and specifications include:

 

Eyewash and eye/face wash controlled, low-velocity flow rinses both eyes and is not injurious to the user

Water flow is sufficiently high to allow the user to hold eyes open while rinsing

Spray heads are protected from airborne contaminants - covers are removed by water flow

Plumbed eyewash delivers at least 0.4 gallons of water per minute at 30 pounds per square inch pressure for 15 minutes

Gravity-fed (self-contained) eyewash delivers at least 0.4 gallons of water per for 15 minutes

Plumbed eye/face wash delivers at least 3.0 gallons of water per minute at 30 pounds per square inch pressure for 15 minutes

Gravity-fed (self-contained) eye/face wash delivers at least 3.0 gallons of water per for 15 minutes

The water flow pattern is positioned between 33 and 53 inches from the surface on which the user stands and at least 6- inches from the wall or nearest obstruction

The valve actuator is easy to locate and readily accessible to the user

The unit washes both eyes simultaneously and covers the area indicated on test gauge at no more than 8 inches above spray heads.
