Safety Procedures & Tool Usage Flashcards

Why is it important to wear safety glasses in the shop?

Answer: To prevent eye injury

Wearing safety glasses is a fundamental safety practice in any automotive shop environment. They provide essential protection for the eyes from flying debris, chemical splashes, dust, and other potential hazards that can cause severe and permanent eye injuries. Always use them when working with tools, fluids, or under a vehicle.

What should you always do before lifting a vehicle?

Answer: Secure the lift points

Before lifting a vehicle with a hoist or jack, it is absolutely paramount to correctly identify and secure the designated lift points. Improper placement can lead to severe structural damage to the vehicle, instability during lifting, or even catastrophic failure of the lift itself. This poses extreme danger to personnel and equipment, making proper lift point securing a critical safety step.

Which fire extinguisher class is suitable for gasoline fires?

Answer: Class B

Gasoline is a flammable liquid, and fires involving flammable liquids are classified as Class B fires. A Class B fire extinguisher is specifically designed to suppress these types of fires by smothering them or interrupting the chemical reaction. Therefore, it is the appropriate and most effective choice for extinguishing gasoline fires in an automotive setting.

Why should tools be returned to their proper place after use?

Answer: To prevent loss and ensure safety

Returning tools to their designated storage locations after use is a fundamental practice for maintaining an organized and safe workshop. This prevents tools from being misplaced or lost, reduces the risk of tripping hazards, and ensures that the correct tools are readily available for the next task. It significantly improves efficiency and overall shop safety.

What is the purpose of a torque wrench?

Answer: To measure torque accurately

A torque wrench is a specialized tool designed to apply a precise amount of rotational force (torque) to a fastener. This accuracy is crucial in mechanical applications to prevent overtightening, which can damage components or strip threads, and undertightening, which can lead to parts loosening. It ensures fasteners are tightened to manufacturer specifications for optimal safety and performance.

How should chemicals be stored in the workshop?

Answer: In original, labeled containers

Storing chemicals in their original, labeled containers is a fundamental safety practice in any workshop. This ensures that the contents are clearly identified, preventing accidental misuse, mixing of incompatible substances, or exposure to unknown hazards. Proper labeling also provides critical information regarding safe handling, storage requirements, and emergency procedures.

Which PPE is recommended when working with loud power tools?

Answer: Ear protection

Ear protection is essential when working with loud power tools to prevent noise-induced hearing loss, which can be permanent. Prolonged exposure to high decibel levels can severely damage the delicate structures of the inner ear. While other PPE like safety glasses and steel-toe boots protect different body parts, ear protection specifically safeguards against auditory damage.

What is the danger of using a damaged extension cord?

Answer: Risk of shock or fire

Using a damaged extension cord, especially one with frayed insulation or exposed wires, presents a serious risk of electrical shock or fire. Exposed conductors can directly shock a user or short circuit, generating excessive heat that can ignite flammable materials. Always inspect cords for damage before use and replace any that are compromised to ensure electrical safety.

Why should jack stands be used instead of only a floor jack?

Answer: They provide added stability and safety

Jack stands are critical for safety when working under a vehicle because they provide stable, mechanical support that a hydraulic floor jack alone cannot guarantee. A floor jack is designed for lifting, but it can fail due to hydraulic leaks or accidental release, posing a severe risk of injury. Jack stands securely hold the vehicle in place, preventing it from falling.
