Work Coveralls

Employers must ensure that employ- ees who handle minimal exposure pesticides are provided with—and wear—coveralls. This is true regardless of the toxicity category of the product. Employers must ensure that

  • employees start each workday wearing clean coveralls

  • they keep at least one change of clean coveralls available at the mixing and loading site

  • employees change out of their coveralls and wash themselves at the end of their workday

  • employees do not take home potentially contaminated coveralls they remove at the work site or at headquarters

  • employees whose workday does not require them to return to their employer’s headquarters must remove and store their contami- nated coveralls in a sealable container outside of their own living quarters and return them later to their employer

Employers must provide for the laundering of coveralls. They must inform the person or firm doing the laundry that they will receive pesticide- contaminated clothing and that it should be laundered separately.

Full-Body Chemical-Resistant Protective Clothing. Employers must provide—and ensure that employees wear—full-body chemical-resistant protective clothing when employees handle minimal exposure pesticides. This clothing must cover the torso, head, arms, hands, legs, and feet of the employee. Employees working in the following situations are not required to wear full-body chemical-resistant protective clothing, but this clothing must be immediately available for use in an emergency:


  • employees using a closed system or sealed water-soluble packets while mixing, loading, or transferring minimal exposure pesticides. These employees must instead wear a chemical-resistant apron, chemical-resistant gloves, and chemical-resistant boots.

  • employees working as applicators or flaggers in enclosed vehicles

  • applicators using vehicle-mounted or towed equipment to inject or incorporate minimal exposure pesticides into the soil

  • applicators using equipment with vehicle-mounted spray nozzles that are directed downward and located below the level of the employee

Closed Systems

Employers must provide and ensure the use of a closed system for all employees who mix, load, or transfer liquid formulations of minimal expo- sure pesticides, or who load diluted liquid mixtures derived from dry formulations of minimal exposure pesticides, regardless of their toxicity category. Closed systems are not required for employees who handle a total of one gallon or less of minimal exposure pesticides per day exclusively in original containers of one gallon or less.

Respiratory Protection

Employers must provide—and require employees to wear—respiratory protection when they engage in

  • hand application or ground application of minimal exposure pesticides

  • flagging during an application of a minimal exposure pesticide, except flaggers in enclosed vehicles

  • mixing and loading dry formula- tions of minimal exposure pesti- cides, except when mixers or loaders use sealed water-soluble packets
