How does the On-Site (S19-921) compare to the single use, preserved and sterile solution used in portable fixtures on the market?
The On-Site allows people to view the contents inside the tank, activate the fixture, and still have enough fluid to satisfy the 15 minute flush requirement, provided that the water is not below the fill line. Competitive preserved and sterile portable eyewashes do not feature a clear tank, and allow for a single activation only. After that single activation, the unit is no longer compliant, and new pouches must be ordered and installed. This significantly increases the cost to maintain the fixture.
