If your company works with chemicals, storing them safely can be a
problem. What the problem is, depends on what the chemical is, how it is
stored and what measures are in place in case of accidents.
Storing chemicals properly and safely should prevent
accidental leaks, spills and fires, and it is very important to store
them in the correct manner. Obviously, “prevention is better than cure”,
but as some leaks and spillage are almost inevitable, dealing with
problems is also an important part of safety procedures.
The
first thing to look at is the type of chemical to be stored, as this
will also tell you how stable, or indeed unstable, it is. It will also
tell you how dangerous it is, how toxic, and what measures are needed in
case of accidents.
Segregate chemicals – there are some, that when mixed together cause reactions that each one individually would not have.
Toxic
chemicals should be stored in well ventilated storage areas that have
solid floors and shelves and no direct sunlight. This means in case of
accidents, fumes will not gather and the chemical will not be absorbed
by the materials around it. (Once it is absorbed it will be next to
impossible to remove, making the whole area dangerous for an undefined
period of time.)
The storage room used should be locked, with
access limited to personnel trained in dealing with each product, both
in handling and in damage control. Do not store combustibles, equipment
or other items in the storage area with the chemicals, the former could
cause a fire and the latter two may be needed to clear it up.
Make
sure the containers used really suit the type of chemical. Many
chemicals have different needs. A very ordinary procedure, that is
perhaps the easiest to overlook – make sure lids etc. are closed
properly and tightly.
Keep a proper inventory of chemicals at all times. Know where everything is and how much is available.
Ensure
the containers holding the chemicals are labeled at all times,
immediately replacing any label that is unreadable or absent. The label
will tell anyone near the container, not only what is in it, but also
how to behave near it, (many chemicals are highly flammable, so sparks
must be avoided), and how to react in case of an emergency.
Make
sure protective clothing and whatever products needed to contain and
clean up any spills, leaks or fires, (water, sand, lime etc), are quick
and easy to access. Fire extinguishers should be checked regularly,
although this is the law anyway in many countries, and as such the
authorities will come out to check them.
Do check for leaks or spills regularly and keep emergency numbers in an area where everyone can find them quickly and easily.
