Corrosion and scale inhibitors (for example Nalco products) are commonly found and used in shipboard
applications.
It is vital to consult the accompanying
MSDS
prior to use onboard.
The precautions to take with corrosion and scale inhibitors are very similar to those for cooling agents and
are detailed in the applicable
MSDS
data for each type of agent.

The
MSDS
indicates any segregation requirements of a particular hazardous material.
Hazardous materials are by nature dangerous and this danger can be magnified by incorrect stowage and
loading positions on a vessel’s deck if consideration is not given to the proximity of other hazardous
materials.
