Personal Protective Equipment and Human Safety
The label sets the floor
PPE required on the label is the minimum for that product and that task. Mixing and loading usually demand more protection than application - gloves, apron, and eye protection at the mix station are the classic example. Never substitute: leather or cloth gloves absorb and hold pesticide against skin. Use chemical-resistant gloves (nitrile, butyl, neoprene) matched to the solvent, and wash them before removing.
Respirators
Cartridge respirators require fit testing, training, and a cartridge change schedule. A dusty wettable-powder load is a respiratory exposure event. A tight-fitting respirator on an unshaven face leaks. Trap: assuming a dust/mist mask equals an organic-vapor cartridge.
Exposure and poisoning
Organophosphates and carbamates cause cholinergic signs: salivation, lacrimation, sweating, vomiting, diarrhea, pinpoint pupils, slow pulse, muscle twitching. Take the label and SDS to the hospital and call the poison center number printed on the label. Do not induce vomiting unless instructed.
Heat
Full PPE in July is a real heat-illness risk. Manage it with work-rest cycles, shade, hydration, and early starts - not by shedding PPE. Trap: questions dangling 'it is hot' as a reason to remove gloves or a respirator.
Worked example
A label requires mixers and loaders to wear coveralls over long sleeves and pants, chemical-resistant gloves, and goggles, and requires applicators to wear gloves and long pants. If you mix, the mixing standard applies even if you spray for only five minutes.
Other basics
Wash work clothes separately from family laundry, wash PPE after each use, store PPE and pesticides away from food, and know the minimum age requirement for handling pesticides under the Worker Protection Standard.
