Which statement about emergency response planning is true?
The main reason to have an emergency response plan is to reduce economic losses.
The first person to contact in an emergency is an attorney.
It is important to make a detailed report of what took place before, during, and after the incident.
What is the backbone of any emergency response plan?
Outlining the sequence of actions to take in a crisis
Knowing where labels and SDSs are kept.
Having a designated emergency responder.
In addition to an emergency response plan, which of the following will further reduce the risk of a pesticide fire?
. Store pesticides close to a heat source to prevent freezing.
Keep a fire-detection system in the storage area.
Post the storage area with a warning sign.
Which is a recommended action to take in the event of a pesticide fire?
Construct berms to contain contaminated runoff water.
Enter the storage facility and remove as much pesticide as possible
Try to extinguish the fire before calling 911.
Which is an appropriate action to take in the event of a pesticide spill?
Take a “time out” to read your emergency response plan.
Call 911 only if the spill has a chance of entering surface water
Put on the appropriate PPE before responding to the spill.
Determining when to apply a pesticide includes considering the:
Life cycle of the pest and weather conditions
Percent active ingredient.
Need for additives or adjuvants.
The “Directions for Use” section of a pesticide label indicates the:
Various crops or areas on which the pesticide may be legally used.
Disposal of pesticide waste.
Environmental, physical, and chemical hazards.
When two or more pesticides mixed together form a putty or paste, separate into layers, or look like cottage cheese, it is an example of:
Limited agitation.
Chemical incompatibility.
Physical incompatibility.
After filling a tank one-fifth to one-half full with carrier, what is the usual order for tank mixing the remaining products?
Add suspension products, add emulsion products, add solution products, add surfactants (if needed), add compatibility agent (if needed).
Add compatibility agent (if needed), add suspension products, add solution products, add surfactants (if needed), add emulsion products.
Add surfactants (if needed), add suspension products, add emulsion products, add solution products, add compatibility agent (if needed).
Which statement about the proper technique for opening pesticide containers is true?
Put on the appropriate PPE after the containers have been opened.
Use a sharp knife or scissors to open paper or cardboard containers.
Leave the container open until you have finished mixing pesticides for the day.
Which statement about measuring and/or transferring pesticides is true?
Metal measuring utensils are recommended over plastic.
Most dusts, powders, and dry formulations are measured by volume.
After adding the pesticide to the partially filled spray tank, rinse the measuring container and pour the rinse solution into the tank.
Which statement about cleaning and disposing of pesticide containers is true?
Do not puncture rinsed pesticide containers.
Pesticide containers that cannot be recycled or returned to the manufacturer should be reused.

A nozzle that mainly produces fine droplets is likely to minimize off-target drift
Coarse-sized droplets provide maximum coverage of the target.
Nozzles control the amount of material applied and type of pattern created.
