Pesticides coming into contact with the skin can rapidly enter the body. Successful decontamination of body surfaces requires:
Anyone contaminated with pesticide should strip off their clothing and quickly and thoroughly scrub the affected part of their body with soap and water. This should be followed by careful rinsing and towelling dry (Figure 26).

Contaminated protective clothing should be
thoroughly washed using industrial grade detergent followed by
several rinsings. Protective clothing should not be washed with the
family wash. Gloves should be worn when washing protective clothing.
Hot water should be used when available. Washed clothes should be
hung to dry in full sunshine.
Where there is a large patch of fabric that has
been contaminated by toxic concentrates and replacement clothing is
available, it is best to destroy the affected clothing by burning.
When dealing with leaks and spills, water, soap
or detergent are usually the most readily available materials for
decontamination. However, other chemicals sold for domestic or common
commercial purposes may be useful too.
Organophosphorus compounds can be treated by sodium
hypochlorite (bleach) and sodium carbonate (washing soda), which are
useful for decontamination and can be applied following initial
scrubbing with soap and water.
Organochlorine compounds are persistent chemicals
and household ammonia and washing soda can be used, but the main
method is to scrub with water and detergent.
Carbamates should be scrubbed with washing soda or strong soap.
Transport vehicles should be decontaminated
thoroughly as soon as spills or leaks are seen, otherwise there is a
danger that when used subsequently for other goods, including
foodstuffs, the goods could become contaminated (Figure 27). Spills
are cleaned up in the same way that they are in stores. The
contaminated washings from the vehicle should be absorbed by sawdust,
sand or dry soil and placed in a container for collection and central
disposal by the national authority.
