There are three main safety hazards on a lime slaker to be aware of:
- Moving Parts
- Chemical Lime
A slaker should be operated at as close to boiling as possible to get the best possible lime slurry quality. As such, there are numerous hot surfaces that could potentially cause burns. The slurry itself is also very hot so hatches should remain closed to prevent splashing.
The slaking system should also be designed to measure and address high temperature excursions, by stopping the feed of lime and cooling the reaction with water where necessary.
Regardless of the type of slaker being used there will be some form of rotating equipment used for mixing. These moving parts should be suitably guarded to prevent personal contact.
Lime, even when cool, can be irritating to the skin and damaging to the eyes. The MSDS (Material Safety Data Sheet) for the particular product being handled at your facility should be referred too for treatment and protection recomendations.
