101PD SAMPLEChapter 1 — Site Preparation and the Label (15% of the exam) High-yield review. Full doctrine: Treatise Ch. 1. Supplements — never replaces — the Board's study references. Not affiliated with SPCB, DPR, or PSI. §1.0 The exam and license frame PSI computer exam · pass 70% (BPC 8560) · $60 application · 6-month window · 15-day retake wait · $35 license + Live Scan after passing · 3-yr renewal · CE 12 hrs = 4 R&R + 6 PAU + 2 IPM. Official domains/weights: application 23 · environment 20 · safety 16 · label/site 15 · equipment 14 · notice/IPM 12. Branches: 1 fumigation · 2 general pests · 3 wood-destroyers. Tiers: operator (qualifies company) · field rep (inspects, recommends, bids) · applicator (applies, employed by a registered company). §1.1 Label law The label is the law — use inconsistent with labeling violates federal law. Anatomy: brand + active ingredient % · EPA reg. number · signal word (DANGER/POISON WARNING CAUTION — worst acute route) · precautionary/PPE · first aid · environmental hazards (bee box, aquatic box, impervious-surface sentences) · directions for use (SITES listed = sites lawful; unlisted site = unlawful) · storage & disposal · misuse statement. California adds DPR registration. Labels attached govern over web versions; each jug is its own law. §1.2 Dilution arithmetic Gallon = 128 fl oz. 1:128 = 1 oz/gal · 1:64 = 2 oz/gal · 1:32 = 4 oz/gal. Percent: finished vol × target% ÷ stock% (0.5% from 25%, 1 gal = 2.56 fl oz). % → ppm: ×10,000. Granular: lb per 1,000 sq ft × area. The label's table BEATS your arithmetic. Mix per label order (water first for ECs), dedicated marked measures, mix only what the job needs. §1.3 Formulations EC (solvent/emulsifier — penetrates, odor, surface risk) · WP (agitate; visible on dark; holds on porous) · SC/F (WP performance, easier) · ME/CS (encapsulated — low odor, long life) · G (soil/turf) · D (voids/cracks — light puffs) · B (gels/stations — placement is everything; sprays contaminate) · RTU · fumigants = Branch 1. Match: porous → WP/SC · odor-sensitive → ME/bait · void → dust · kids/pets → tamper-resistant stations. §1.4 Site preparation Read work order + label together (food areas restrict methods) · verify pest/conditions · stage occupants, pets, food out per label · aquarium covered, pump off · food surfaces cleared/covered · labeled service containers only · PPE on BEFORE concentrate · plan reentry communication. Resolve every hazard BEFORE application. §1.5 AI families Pyrethroids (-thrin: residual backbone, aquatic poison, paresthesia, repellent) · pyrethrins (+PBO) · OPs/carbamates (cholinesterase history + symptom cluster) · neonicotinoids · fipronil (transfer effect) · IGRs (cycle-breakers) · borates · desiccant dusts (physical, resistance-proof) · rodenticides (FGAR multi-feed/vit-K antidote · SGAR restricted · bromethalin NO antidote) · sulfuryl fluoride (Branch 1). §1.6 Drill bank — 12 rapid checks 1. Unlisted site? — Unlawful. 2. Table vs math? — Table. 3. 1:64 in 3 gal? — 6 oz. 4. Signal word measures? — Acute
