Routine pesticide store
- The storekeeper should put on essential protective clothing
(overalls and boots) upon arrival at the pesticide store.
- There should be a quick daily inspection of drums and
containers to ensure that there have been no overnight spills or
- Spilled and leaked pesticide must be cleaned up immediately,
using the methods described in section "Spills,
leaks and disposal of containers and chemicals".
- Drums and containers should be thoroughly inspected monthly
for leaking seals, split seams and corrosion.
- Leaking or old drums should be removed and their contents
transferred to empty containers. Appropriate protective clothing
should be worn and precautions taken as described in section
"Personal safety and protective clothing".
Replacement containers should be sealed and relabelled.
- Transfer of chemicals to new containers should be recorded on
the stock record sheet.
- Dates on labels of containers in the store should be checked
monthly and outdated stock separated for disposal. Any labels in
poor condition should be replaced.
Arrival of a consignment of pesticides at the store:
- The back of the transport vehicle should be checked for spills
and the containers for leaks or broken seals; the vehicle should
be decontaminated of any spills. Chemicals from containers with
leaks or split seams should be transferred to empty containers in
good condition and relabelled.
- Pesticide containers should be carefully unloaded from the
delivery vehicle. The delivery note should be examined and
check-list of chemicals arriving at the store should be prepared
on a stock record sheet.
- Containers of chemicals placed in the store should be set on
floor dunnage and stacked using wooden pallets as necessary.
- The location of chemical containers in the store should be
recorded on the stock record list.
Taking pesticides from the store for pest control purposes
- The condition of the transport vehicle should be checked
before placing containers of pesticides in it. It should also be
ensured that no foodstuffs are to be carried on the same vehicle.
- The removal of pesticides from the store should be recorded on
the stock record sheet.
- The stock first deposited in the store should be the first to
be taken out.
- Pesticide containers should be carefully loaded on to the
despatch vehicle and the driver provided with a delivery note.
Ten rules for proper
pesticide storage and stock management
- Pesticide stores should not be located in or near densely
populated urban areas or near water bodies.
- The storage capacity (total storage surface) should be
sufficient to store the total stock of pesticides at any time.
- Each store should have at least the following:
- sufficient ventilation openings to avoid unnecessarily high
- floors made of, or covered by, impermeable concrete or
cement (as a temporary measure, floors may be covered by a
large and thick polyethylene sheet);
- ramps at entrances to contain any major leakage within the
- doors that are lockable and bars across ventilation holes
and windows to prevent unauthorized entry.
- The floor of the store should have a layout of separate blocks
with aisles between them. Ideally the outline of the blocks should
be painted on the floor. Each block should contain only one
product. There should be sufficient space between blocks to move
containers freely, enable the inspection of containers and treat
leakages. Drums should be stacked in such a way that each can be
inspected from the aisles between the blocks. Drums and bags
should be stored on pallets. The number of containers stacked on
top of each other should not exceed the stacking recommendations
for the type of container concerned. Overstacking may lead to
rupture of containers lower down and reduces access to containers.
- Pesticide stores should only contain pesticides. All other
goods or objects should be removed.
- Obsolete pesticides should be separated from operational
- Each store should have the following for dealing with
- a few bags of sawdust and/or sand to absorb leaked or
- a number of empty containers (preferably salvage drums that
can contain a whole 200-litre drum) and empty bags to repack
heavily damaged or leaking containers;
- spade and brush;
- fire extinguisher;
- protective gear for staff to enable them to deal with
emergencies (nitrile rubber or neoprene gloves, rubber boots,
overalls, goggles, vapour masks or half-face respirators with
organic vapour cartridges)
- water supply from a tap, or a container of water, to wash
hands and face if these become contaminated;
- eyewash set.
- The contents of leaking or heavily damaged containers should
be repacked in appropriate replacement containers. Repacked
pesticides should be labelled immediately. Stores should be
inspected regularly. Any leakage or contamination should be
cleaned up immediately.
- Storekeepers should keep a record of the stocks in their
custody and a separate record of stocks in the country should be
kept centrally. Recorded data should include: for incoming
pesticides, the arrival date, formulation, quantity, unit size,
date of manufacture, supplier and origin; for outgoing pesticides,
the date, formulation, quantity, unit size and destination.
Records should be updated regularly.
- A "first in - first out"principle should be applied
consistently. In other words, always finish old consignments
before using newly arrived consignments.
