Under the Hazard Communication Standard (29 CFR 1910.1200), if you use Nalco 3DT 449, you must: Understanding these properties helps in both safety and
The 15-minute eyewash requirement is non-negotiable — not 2 minutes, not “until it stops stinging.” The MSDS reinforces the urgency. Why this matters: The presence of hydantoins means
Nalco 449 is a high-performance internal treatment chemical designed for steam boilers. It is a "phosphate-based" program used to control scale and corrosion in boiler systems.
This is proprietary, but the SDS must list hazardous ingredients. Typical components include:
Why this matters: The presence of hydantoins means that in the presence of water, the product releases both bromine and chlorine gases.
