The Haws 9082 is a bacteriostatic eye wash water preservative additive for use in portable eyewash stations. Sold as a 4-pack of 8 oz. (236 mL) bottles, the 9082 is used to help preserve potable water in self-contained eyewash tanks between scheduled water changes.
Each 8 oz. bottle treats 5 to 20 gallons (18.9 to 75.7 L) of potable water for up to four months. Haws lists the 9082 as FDA-compliant, with a 2-year shelf life and storage requirements of 68–77°F (20–25°C).

Why Portable Eyewash Stations Need A Preservative
Portable gravity-fed eyewash stations hold potable water in a tank so they can deliver emergency flushing fluid when a plumbed eyewash is not available. Because that water may sit in the tank between scheduled maintenance intervals, a bacteriostatic preservative helps maintain the integrity of the water during storage.
The Haws 9082 is designed for Haws portable eyewashes, overhead tank showers, and air-charged tempered shower systems where stored water needs to be preserved. It is not a cleaner, sanitizer, or substitute for proper tank maintenance. Always start with clean potable water and follow the maintenance instructions for your specific eyewash station.
How To Use The Haws 9082
Use one full 8 oz. bottle of Haws 9082 per eyewash tank fill for units with capacities from 5 to 20 gallons.
- Fill the portable eyewash tank with clean potable water.
- Add one full 8 oz. bottle of Haws 9082 preservative concentrate.
- Follow the operating manual for your specific eyewash station.
- Replace the treated potable water on the manufacturer's recommended schedule.
- After any full 15-minute ANSI activation test, refill the tank with clean potable water and add a new bottle of 9082.
Important: The 9082 concentrate must be diluted with potable water before use. Do not put the concentrate directly into eyes — contact with the concentrate can cause irritation.
What Equipment Is The 9082 Designed For?
Haws specifies Model 9082 for use with Haws portable eyewashes, overhead tank showers, and air-charged tempered shower systems where the integrity of stored water needs to be preserved.
Common Haws portable eyewash products that may use preservative additive include:
- Haws 7501 Portable Gravity-Fed Eyewash, 9-gallon

How Much Will A 4-Pack Cover?
Each carton includes four 8 oz. bottles. Each bottle treats one tank fill from 5 to 20 gallons.
- One portable eyewash station: one 4-pack covers up to four scheduled refill cycles.
- Four portable eyewash stations: one 4-pack covers one fill cycle for up to four stations, when each station holds 5 to 20 gallons.
- Large facilities: order based on the number of stations and your refill schedule.
The Haws product page and spec sheet list a 2-year shelf life, so facilities with multiple portable eyewash stations can keep extra bottles available for scheduled maintenance.

Can I use this with any portable eyewash station?
Haws specifies the 9082 for Haws portable eyewashes, overhead tank showers, and air-charged tempered shower systems. If you are using another manufacturer's portable eyewash station, check that unit's operation manual or use the additive specified by the tank manufacturer.
Is the 9082 a sanitizer or disinfectant?
No. The 9082 is a bacteriostatic preservative additive for potable water in portable eyewash equipment. It is not a sanitizer, disinfectant, or water purifier. The tank must be filled with clean potable water.
What is the shelf life of an unopened bottle?
