FUMIGATION 101

PART 1 : WHY FUMIGATE ?


3/26

REASONS FOR FUMIGATION

Insects are present in almost all environments.

Grain insects can go into the product we workwith, once it is in the product the product is said

to be infested. Customers (including you and me) will not use

infested product.

If customers find insects in our product, they will

not buy our brand again, so we lose them ascustomers.

Insects and rodents cause damages and presentsa health risk.

INSECT BEHAVIOUR


5/26

The insects we talk about here, are the ones

that feed on grain or grain products.

They are divided into 2 broad groups: The primary group who eats and lay their eggs

in whole grain kernels.

The secondary group who eat and lay theireggs between kernels or the dust of grain

products.

Grain Insects


6/26

INSECT BEHAVIOUR

All grain insects lay eggs.

The eggs hatch and a young insect appears

In many cases, the young insect is in adifferent form than the adult. i.e. a moth layeggs that becomes a worm, then a pupa andonly then a moth again.

This is called the insects life cycle The better the environment is, the quicker the

life cycle of the insect.

IDEAL INSECT ENVIRONMENTS

Any place where there is food and moisture

available for the insect to feed on.

Any place that is not disturbed (cleaned). Any place where normal cleaning and

treatments does not reach. (Cracks, ledges,

inside closed spouts conveyors etc.)

Any place warm and moist.

METHODS OF INSECT CONTROLL


10/26

METHODS OF INSECT CONTROLL

Mechanical Removal by screening, crushing,

remove by hand etc.

Chemical Kill with chemicals calledFumigants or Insecticides

Environmental Make the environment

unbearable for insects to live in heat, cold,

remove oxygen, remove food and nesting

places.


11/26

Methods of Insect Control

Mechanical controls are not very effective in a

factory environment, insect eggs are so small

that they can not even be seen by us.

So we try to firstly manage the environment in

such a way that insects are not comfortable to

nest and multiply.

This is done by regular cleaning and deep

cleaning.

Cleaning and sanitation still is the best way to

prevent, control and eliminate infestation.


12/26

Methods of insect control

The last resort we use to wipe out insect

infestation is the application of chemicals.

This is NOT the first choice as it comes withmany negative side effects.

1. Chemical residues in food product.

2. Dangerous for the people applying it.3. Loss of production time.

Fumigants defined


15/26

Fumigants

A fumigant is a chemical compound with the

inherent ability to kill living organisms.

Another word for fumigant is pesticide orsimply poison.

Almost all chemicals are poisonous at different

dosages. For example ordinary table salt can

kill a human if he ingests too much, approx

300g taken in one go would kill an adult male

human.


16/26

Fumigants -

The fumigants we use are selected because

they possess certain properties:

1. High efficiency low dosage required to killmost insects. (Low LD50 value)

2. Relatively safe to apply.

3. Relatively easy to apply.4. Low risk residue.

5. High penetration properties (Reach insects in

their hiding places)

Dangers and precautions


18/26

Insecticides : Dangers and

precautions In the previous section we made it clear that

insecticides are used to kill insects.

This means that it is also dangerous for humans,

animals and plants and prolonged exposure to high

dosages can certainly cause illness or death in

humans and animals.

Concentrated insecticides are especially dangerous

since they deliver extremely high dosages.

While diluted insecticides can also be dangerous,

they are seldom harmful to humans.


19/26

Insecticides : Dangers and

precautions Although some people assume that a person would

have to drink insecticide to get sick from it, there are

other ways these chemicals can end up inside the

body.

1. Ingestion A person can drink it or accidentally get

it in the mouth.

2. Inhalation A person can inhale the fumes or mists.

3. Skin absorption A persons skin will absorb any

chemical that is on it for a long period.

4. Transferred A person might eat, drink or smoke

products that got the chemical on it.

SAFETY FIRST


21/26


22/26

Safe use of insecticides

Make sure your gas-mask canister is of the

correct type and not expired.

Make sure the equipment you use are inorder.

Make use of a buddy system, never apply

insecticides alone, someone MUST be with

you or know where you are.

Know first aid and help any person in danger

immediately, it can be a life or death situation!


23/26

Safe use of insecticides

Wash your hands with plenty of soap and

running cold water. (Hot water causes skin

absorption)

Empty your pockets. Fumigated cigarettes are

more poisonous than regular ones!!

Make sure your food is not exposed.

Shower after spraying

Clothes must be taken off as soon as possible

and washed before wearing again.


24/26

Safe use of insecticides: Material

safety data sheets. Material safety data sheets are pages with all

the relevant information to the insecticide you

are using.

These sheets must be kept in the fumigant

store.

These sheets also has some information on

how to handle the insecticide as well as some

first aid tips and information.

You are entitled and indeed expected to read

the MTDS of the fumigants you are using.


25/26

Safe use of insecticides: The

environment. As we said previously, insecticides can be

harmful to humans, animals and obviously

insects.

Not all insects are harmful and some actually

plays an important role in the ecosystem.

We are guardians of our environment and

must ensure we use insecticides in such a way

that only the intended group of insects are

killed. And nothing or nobody else.


26/26

Safe use of insecticides: The

environment Never spray insecticides unnecessarily.

Never use in an area where it is not supposed

to be used. Dangerous chemicals must be discarded in a

safe manner. Never pour in a drain, toilet etc.

Use the correct product at the correct dosage.
