SECTION ONE: QUESTIONS 1 – 100
1. When performing routine maintenance on a gasoline-powered mower, what is the MOST
critical safety step to take before beginning any inspection or repair?
A. Check the oil level.
B. Remove the spark plug wire.
C. Inspect the air filter.
D. Sharpen the mower blade.
🟢B
🔴 Explanation: Removing the spark plug wire prevents the engine from accidentally starting while
you are working on it, which is the primary safety hazard. The other options are important
maintenance tasks but do not address the immediate risk of accidental ignition.
2. A park irrigation system is showing signs of low water pressure in a specific zone. What is the
FIRST thing a maintenance worker should check?
,A. The main water supply valve.
B. The condition of the sprinkler heads in that zone.
C. The irrigation controller's programming.
D. The system's backflow preventer.
🟢B
🔴 Explanation: The most common cause of low pressure in a specific zone is a broken or missing
sprinkler head, which creates a large opening and reduces pressure for the rest of the zone.
Checking the heads is the quickest and most logical first step before investigating more complex
issues.
3. Which of the following is an example of a Class A fire extinguisher?
A. A fire extinguisher intended for use on electrical fires.
B. A fire extinguisher intended for use on flammable liquids.
C. A fire extinguisher intended for use on ordinary combustibles like wood and paper.
D. A fire extinguisher intended for use on cooking oils and fats.
🟢C
🔴 Explanation: Class A extinguishers are designed for ordinary combustibles such as wood, paper,
cloth, and trash. Class B is for flammable liquids, Class C is for electrical fires, and Class K is for
cooking oils.
4. What is the primary goal of Integrated Pest Management (IPM) in a park setting?
A. To completely eliminate all insects and pests.
B. To use the strongest chemical pesticides for immediate results.
C. To manage pest populations at acceptable levels using the least hazardous methods.
D. To rely solely on natural predators for pest control.
🟢C
🔴 Explanation: IPM is a sustainable approach that focuses on long-term prevention and control of
pests through a combination of techniques. It aims to minimize risks to human health and the
environment by using the most effective and least toxic methods available.
5. A park visitor reports a large, broken branch hanging dangerously from a tree near a picnic
area. What is the appropriate initial action?
A. Immediately cut the branch down with a chainsaw.
B. Close off the area and post warning signs.
C. Ignore the report until more pressing tasks are completed.
D. Call a certified arborist to remove the branch.
🟢B
🔴 Explanation: The immediate priority is to protect the public from the hazard. The area should be
cordoned off with caution tape and signs should be posted. The maintenance worker can then
assess the situation and determine if they have the tools and training to remove it safely, or if a
certified arborist needs to be called.
, 6. When mixing fertilizer for a sprayer, the general safety rule "P.P.E." stands for:
A. Physical Protective Equipment.
B. Personal Protective Equipment.
C. Primary Personnel Equipment.
D. Professional Practice Equipment.
🟢B
🔴 Explanation: Personal Protective Equipment (PPE) includes items like goggles, gloves,
respirators, and protective clothing. These are essential to protect the worker from chemical
exposure during mixing and application.
7. The "Root Crown" of a tree is best described as:
A. The topmost part of the tree's canopy.
B. The area at the base of the trunk where roots meet the soil.
C. The main lateral root of the tree.
D. The scar left on a branch after pruning.
🟢B
🔴 Explanation: The root crown is the critical transition zone between the tree's trunk and its root
system. Keeping this area exposed to air is vital for the tree's health; covering it with soil or mulch
can cause decay and girdling roots.
8. Which of the following chemicals is commonly used to maintain the proper pH level in
swimming pool water?
A. Chlorine
B. Bromine
C. Sodium bicarbonate (baking soda)
D. Muriatic acid
🟢C
🔴 Explanation: Sodium bicarbonate (baking soda) is used to raise the total alkalinity and pH of
pool water. Chlorine and bromine are sanitizers, while muriatic acid is used to lower pH and
alkalinity.
9. A worker is using a power auger to dig post holes. What is the MOST important safety
precaution to take?
A. Ensure the auger bit is sharp.
B. Have a coworker nearby to assist.
C. Identify and mark all underground utilities before starting.
D. Keep the engine speed high for best performance.
🟢C
🔴 Explanation: Contacting an underground utility line (gas, electric, water, or sewer) can be
catastrophic and life-threatening. Calling 811 to have utilities marked is the single most important
safety step before any digging activity.
