3.11 Chemicals and Safe Procedures. Dedicated Guidelines

(8) Avoid splashing when preparing solutions, and always pour a chemical into
the water and not vice versa; any splashes will then contain a more dilute
solution. Interestingly, this ‘chemical’ rule should be repeated always in spite
of its apparent simplicity.
(9) Strictly observe instructions relating to dilution and needed quantities when
speaking of pre-impregnation operations on production lines.
(10) When cleaning a surface with a cloth, impregnate the cloth instead of the
surface to be cleaned in order to avoid any emanation.
(11) Limit spraying only to the maintenance of inaccessible spaces with a cloth;
ensure that the sprayed product is used safely.
(l2) Check the useful life of a product after dilution to ensure the effectiveness of
the solution used; refer to manufacturer’s information.
(13) Always respect the contact time of used products. Germicides should never be
wiped off.
(14) Store products in a secure and safe way.
3.11.2 The Sinner’s Circle
A perfect cleaning requires the use of products fit for the desired action(s): degreasing, scrubbing, descaling, etc. Moreover, the type(s) of cleaning tools have to be
considered. To accomplish this mission, the ‘Sinner’s Circle’ considers four simple
factors which, when used together, will provide an undeniably more efficient cleaning job than any detergent used alone (Von Rybinski 2007). These four inseparable
elements are:
(1) Chemistry (chemical action)
(2) Mechanical power (action)
(3) Contact time
(4) Temperature.
Under certain conditions, the increase of one of the parameters can improve the
result of the whole.
3.11.2.1 Chemical Action
Any product is categorized according to its chemical action (e.g., detergent, floor
finish, and disinfectant). Each chemical has a specific use that must be respected in
order to maximize its effectiveness and avoid any accident.
Each product has a given efficiency according to a specific dilution; it is important
to respect the dilution of each product, as overdose and underdosing may affect the
expected result.
