43. A person who carries out pesticide spraying must, at the time the work begins, post a sign on each entrance to the treated premises if(1) the quantity of pesticides to be applied in the premises is determined by the volume of the premises to be treated; or
(2) the pesticide label of the pesticide states there must be a waiting period after the pesticide application during which access to the premises is prohibited.
That requirement does not apply to a farmer or forest manager.
