2.1 Safety First
What does OSHA Stand for?
Occupational Safety & Health Administration
What does PPE stand for?
Personal Protective Equipment
What is the first step before operating any tool?
Inspect the tool and review the operating procedure.
What is the formula for work?
Work = Force × Distance
Which tool provides the most precise measurement?
Dial caliper
What is pacing used for?
Estimating distance.
What is a Hazard?
Anything that has the potential to cause injury, illness, or damage.
Name two examples of PPE commonly used in the ag shop.
Safety glasses, gloves, hearing protection, steel-toe boots, welding helmet (any two).
Why is choosing the correct tool for a job important?
It ensures the job is done safely, efficiently, and correctly.
What unit is work measured in?
Joules
What is the difference between accuracy and precision?
Accuracy is closeness to true value; precision is consistency.
Why is pacing considered an estimate?
Step length varies, reducing accuracy.
Why are safety standards important in an agricultural mechanics shop?
They reduce the risk of injury, protect workers, and ensure equipment is used correctly.
Why should you assess a situation before providing first aid?
To make sure the scene is safe and prevent further injury.
What is an operating procedure?
Step-by-step instructions for safely using a tool or machine.
What is power?
The rate at which work is done.
Why is precision important when fabricating parts?
It ensures parts fit and function correctly.
What is the 3-4-5 rule used for?
Checking if corners are square.
What is the most common root cause of accidents in the shop?
Human error / unsafe behavior (not following procedures or rules).
Why is PPE selection different depending on the task being performed?
Different tasks have different hazards, requiring different protection.
Explain what could happen if the wrong tool is used for a task.
The tool or material could be damaged, or the user could be injured.
How does increasing force or distance affect work done?
Increasing either increases the amount of work.
When would a combination square be more useful than a tape measure?
When checking squareness, angles, or straight edges.
Why must irregular shapes be broken into smaller shapes to find area?
To calculate area accurately.
Explain why following safety rules protects both people and equipment.
Safety rules prevent injuries and reduce damage to tools, equipment, and facilities.
Explain how improper PPE use could lead to a serious injury.
Improper PPE may fail to protect the body, allowing hazards to cause harm.
Describe why operating procedures must be followed every time.
Skipping steps increases the risk of injury, even for experienced users.
Explain the difference between horsepower and watts and why both are used.
Both measure power; horsepower is common for engines, watts for electrical systems.
Explain why a precise measurement can still be inaccurate.
Measurements can be consistent but not close to the true value.
Explain why accurate measurement is critical before cutting materials.
Incorrect measurements waste materials and create unsafe or poor-fitting projects.
