Personal Protective Equipment and Respiratory Protection

Personal Protective Equipment and Respiratory Protection

Personal protective equipment is the last barrier after product choice, engineering controls, equipment maintenance, and safe work practices. It is still mandatory whenever the label requires it. Read the PPE statement for the exact task: mixers and loaders, applicators, flaggers, cleaners, and early-entry workers may have different requirements.

Select from the label

Common label items include long-sleeved shirt and long pants, coveralls, chemical-resistant apron, chemical-resistant gloves, chemical-resistant footwear, protective eyewear, headgear for overhead exposure, and a specified respirator. “Chemical-resistant” does not mean every rubber-like material resists every product. Use the material category or examples stated on the label and consult the manufacturer’s chemical-resistance data.

If the label requires chemical-resistant gloves, porous leather, cotton, or canvas gloves do not comply. A label may prohibit glove use for a particular fumigant or task, so never add PPE by guesswork when it could trap chemical against the skin. Wear sleeves and gloves in the overlap direction that prevents runoff from entering the glove; that direction changes for hands held above versus below shoulder level.

Chemical-resistant aprons are especially useful during concentrate mixing, loading, and equipment cleaning when the label requires them. Protective eyewear must fit the stated type. Ordinary prescription glasses are not goggles. PPE required by the label is not automatically determined by a product’s signal word.

Inspect, put on, remove, and clean

Before use, inspect gloves for pinholes, seams, stiffness, swelling, or discoloration; check suits and footwear for cracks and worn closures; and check eyewear for visibility and fit. Replace defective items. Keep clean PPE separate from pesticides and contaminated equipment.

At removal, treat the outside as contaminated. Wash gloved hands, peel items off without touching skin, remove gloves without contacting their exterior, and wash hands and face immediately. Shower and change into clean clothes as soon as practical. Follow the product label and PPE maker for reuse limits.

Launder pesticide work clothing separately from family laundry. Handle it with gloves, use the recommended detergent, water level, temperature, and cycle for the fabric and contamination, and run an empty cycle afterward when recommended. Line drying can help prevent contaminating a dryer. Clothing drenched or heavily contaminated with concentrate may need disposal; do not assume hotter water makes every garment safe. Never wash a respirator cartridge or filtering facepiece.

Respirator selection

A respirator must match the exact label specification and contaminant. Particulate filters remove particles; chemical cartridges or canisters address specified gases or vapors; supplied-air or self-contained systems serve different hazards. N, R, and P filter series describe resistance to oil aerosol, while 95, 99, and 100 describe minimum particulate filtration efficiency under test conditions. Those markings do not tell you which pesticide respirator to choose—the label does.

A cartridge has limited service life. Follow the employer’s written change schedule, label, and respirator manufacturer; odor or irritation is not a safe change indicator. Escape immediately if breathing becomes difficult, the respirator is damaged, or breakthrough is suspected.

WPS respiratory safeguards

When the labeling requires a respirator for a WPS handler, the employer must provide a medical evaluation before use, fit testing at least annually for a tight-fitting facepiece, and respirator training at least annually. The employer keeps the required documentation for two years. A user performs a seal check each time a tight-fitting respirator is put on.

Facial hair, eyewear, scars, or head coverings cannot cross or interfere with a tight face seal. Fit-test the same make, model, style, and size used in the field. A medical clearance for one respirator or work condition does not automatically clear a more burdensome device or changed health condition.

An enclosed cab or closed transfer system may permit PPE modifications only when every label and WPS condition for that engineering control is met and the required PPE is immediately available. Leaving the cab or repairing a leak can restore the full PPE requirement.

On exam problems, first locate the label’s task-specific PPE, then check chemical resistance and condition, and finally add the respiratory program steps whenever the label specifies a respirator.

Heat stress and PPE

PPE can increase heat load. Schedule heavy work for cooler periods when the label and weather permit, provide shade and drinking water, use work-rest cycles, and train coworkers to recognize heat exhaustion and heat stroke. Never remove required PPE to cool down inside the exposure area. Leave safely, decontaminate as needed, and cool down in a clean area. Heat illness and pesticide poisoning can share headache, weakness, nausea, or confusion, so treat severe symptoms as an emergency and provide responders with the pesticide label and work history.
