Other safety precautions for the handling of lime
are as follows:
An efficient dust-collecting system should be
used whenever dust is present at handling points.
A dry-pickup vacuum cleaner should be used for
removing dust around unloading equipment and
Protective clothing should always be worn for
persona! safety in case bags break or the dust-
collection system fails. The proper dress is
heavy-denim clothing with long sleeves,
heavy gloves, bandanas, and trousers tied
around the shoe tops. Chemical goggles and
suitable dust masks should be worn. Any
exposed skin areas should be covered with
Avoid accidental contact of quicklime or
slaked lime with water as it generates exces-
sive heat. Serious skin bums and eye damage
can be caused by contact with hot lime solu-
tion. ALWAYS WEAR CHEMICAL GOG-

HANDLING AND STORING
In handling and storing chemicals, observe all
1. Wear appropriate-type chemical cartridge dust
masks when bags of chemicals or bulk material
are unloaded or otherwise handled. When the
chemical is particularly irritating or dust is
excessive, wear chemical goggles.
2. In handling toxic solutions, a face shield, boots,
gloves, and a rubber apron afford required
protection from splashes or sprays.
3. Store chemicals in a clean, dry place. Store
bagged or mixed chemicals in single or double
rows with access aisles around each stack for
frequent fire inspection. This type of storage
makes it easier to remove burning chemicals.
Store chemicals in separate areas free from
contact with flammable chemicals.
Prohibit smoking when loading and unloading
Do not store flammable chemicals where sparks
from overhead electrical equipment can start a
Use explosionproof wiring and electrical
equipment where flammable chemicals are
stored or handled.
Provide adequate shower facilities for all
personnel handling chemicals.
Give all personnel handling fluorides detailed
Avoid breathing fluoride dust; wash thoroughly
after handling fluorides and clean up all
Respirators, chemical goggles, rubber gloves,
and protective clothing must be worn by all
personnel likely to be exposed to sodium
fluoride or sodium silicofluoride dust. Rubber
gloves and boots and acidproof aprons are
necessary where acids, such as hydrofluoric,
fluosilicic, and hydrofluosilicic, are handled.
Wash protective equipment thoroughly before
and after using.
Take care to prevent dust or acids from entering
open cuts, sores, or lesions.
Provide all fluoride-handling equipment, such
as storage bunkers, weight hoppers, and dry-
feed machines, with devices to keep the dust
hazard down. Acid pumps will be provided with
a clear plastic shield around glands and parts to
protect personnel from acid spray.
Store fluorides in a specific, well-identified
area. Storage in various or changing locations
may result in a mistake in identifying the
chemical. All acid containers will be covered,
well vented, and stored where there is no fire
Containers that have held fluoride compounds
will be disposed of in a safe manner by
personnel protected as described above.
