GRADED A+
- Amount of chemical absorbed.
Dosage
- Size of the organism receiving the chemical.
Toxicity The inherent capability of a chemical substance to cause injury.
Lethal dosage likely to kill 50% of the test organism.
50 ppm or less = Highly Hazardous (Dangerous).
LD50
51 to 500 ppm = Moderately
Hazardous (Warning). 501 to
5000 ppm = Slightly Hazardous
(Caution). More than 5000 ppm
= Relatively Nonhazardous.
-Signs = Visible indication of poisoning that another can SEE in a
Signs vs. Symptoms victim.
-Symptoms = Invisible evidence of poisoning that only the victim
can FEEL.
Medical Antidotes Only prescribed and administered by qualified physicians.
Spray Tank Location Mounted in front of the cockpit and as close as possible to the
center of gravity.
Most widely used spray pump Centrifugal Pump
type?
Centrifugal:
- High GPM rate while working against LOW pressure (25 to 50
psi).
Centrifugal Pump vs. Gear
Pump
Gear:
- Low GPM rate while working against HIGH pressure (>60 psi).
- Weighs more than centrifugal.
- Wettable Powders
