Employers are responsible to provide adequate workplace lighting, to carry out equipment inspection, to notify employees who service application equipment of potential hazards, and to provide closed mixing systems when these are required.
Employers must install shut-off devices on the exit end of all hoses attached to mixing tanks that carry liquid pesticides with the signal word Danger or Warning. These devices must be designed so that they prevent pesticides from splashing onto the employee doing the loading when the employee stops filling the application vehicle’s tank and removes the filler hose from the tank’s inlet. A reversing action pump (or a similar system) that will empty the hose and eliminate dripping once the filling operation has stopped may be used instead.
Lighting. Whenever natural light in a mixing and loading area is not ad- equate to allow an employee to read the label and work in a safe manner, the employer must provide artificial light that is sufficient to allow the employee to perform these activities safely.
Safe Equipment. Employers must assure that the equipment employees

Employers must equip all openings on tanks used for mixing or applying pesticides with tightly-fitting covers that prevent splashes or spills (Figure 5-8). And they must not allow any flexible hose that is under pressure and carrying a liquid pesticide with the signal word Danger or Warning to pass unshielded through the cockpit of an airplane or helicopter.
