Personal Protective Equipment and Human Safety
This domain tests personal protective equipment (PPE) and human safety. The exam focuses on label-required PPE, correct selection, donning and doffing, exposure routes, and heat stress in tropical conditions.
Core rules
- The label sets the minimum PPE. Mixing and loading usually need more protection than spraying because concentrate exposure is highest.
- Use chemical-resistant gloves (for example nitrile), not leather or cotton, for concentrates. Add coveralls, boots, goggles or face shield, apron, and a respirator when the label requires it.
- Don PPE before handling product; check fit and condition. Doff in a set order: remove outer gloves and boots, wash hands, remove respirator from behind, then coveralls, then inner gloves; shower.
- Never eat, drink, or smoke while handling pesticides. Wash contaminated clothing separately; discard disposable items properly.
Worked example
An EC concentrate label requires gloves, goggles, apron, boots, and a respirator for mixing. The correct choice is nitrile gloves, sealed goggles, a chemical-resistant apron over coveralls, rubber boots, and an approved respirator. The reasoning is route-specific: mixing creates splashes and vapour, so eye and inhalation protection matter more than during low-pressure spraying.
Traps
Wearing PPE only while spraying; reusing disposable gloves; cleaning skin with solvent; and ignoring heat stress, which leads to removing PPE at the worst moment.
