COMMON QUESTIONS:

1. What water temperature is required?
Answer: The ANSI standard recommends that the water should be “tepid”. The ANSI 358.1-2004 appendix defines tepid waster as water temperature between 60° F – 100° F.
• In locations where freezing temperatures exist, frost-proof or freeze protected
equipment must be installed.
• In locations where temperatures reach scalding levels from heat or exposure to direct sunlight, scald protection valves must be installed.
 
2. What are examples of areas that may require eyewash stations?
Answer: Work areas and operations that may require these devices include:
• Battery charging areas
• Laboratories
• Spraying operations
• High dust areas
• Hazardous substances dispensing stations
 
3. Do I really need to test (activate) plumbed eyewashes monthly?
Answer: Yes, testing of plumbed units is required to ensure a flushing fluid supply is available
when needed. Flushing helps clear the supply line of any sediment buildup and
minimizes microbial contamination due to sitting water.
 
4. How often do I need to clean and maintain my portable self-contained eyewash?
Answer: Portable eyewashes that mix potable water and preservative should be cleaned and refilled per the manufacturer's instructions, which typically is every four to six months.
 
5. Does bottle eyewash meet the requirements of ANSI for flushing?
Answer: Bottle eyewash is classified by ANSI as personal and does not meet the main criteria of plumbed or self-contained eyewash equipment.
