construction Yr 12 assessment 2 Flashcards
Q: What is the main goal of WHS requirements in construction?
To protect workers from injury or illness by identifying hazards, assessing risks, and applying safety practices.
Q: What is a risk matrix used for?
A: To evaluate the severity and likelihood of hazards in a construction site.
Q: What are the four types of hazards in construction?
A: Physical, chemical, ergonomic, and psychological.
Q: What is the purpose of risk assessment?
A: To identify potential hazards and implement control measures to reduce risk.
Q: What is the difference between elimination and substitution in risk control?
A: Elimination removes the hazard completely, while substitution replaces it with something less dangerous.
Q: Give an example of engineering control in construction.
A: Installing guardrails to prevent falls from heights.
Q: What is PPE in construction?
A: Personal Protective Equipment, such as helmets, gloves, and safety boots, worn to protect workers from hazards.
Q: Why is sequencing operations important in construction planning?
A: It ensures tasks are completed in the most efficient order, preventing delays and mistakes.
Q: What does resource allocation involve in construction?
Ensuring materials, equipment, and labor are available when needed to complete tasks.
Q: How does a time schedule help in managing construction work?
A: It helps set deadlines, track progress, and ensure tasks are completed on time.
Q: What is the formula to calculate the area of a floor?
A: Area = Length × Width.
Q: How do you calculate the volume of a trench?
A: Volume = Length × Width × Depth.
Q: What are the basic steps in performing a construction calculation for a fence?
A: Calculate the number of posts by dividing the fence length by the post spacing and rounding to the nearest whole number.
Q: How do sustainable practices affect construction?
They minimize environmental impact by using eco-friendly materials, reducing waste, and following environmental regulations.
Q: Why is teamwork essential in construction projects?
It ensures tasks are completed efficiently and on time by sharing responsibilities and supporting each other.
Q: What is the significance of waste management on a construction site?
Proper waste management reduces environmental impact and ensures compliance with regulations.
Q: What should be checked before using construction tools?
Ensure tools are maintained, clean, and safe to use by inspecting for damage, rust, or missing parts.
Q: What is the role of PPE when using power tools?
A: To protect workers from potential hazards such as flying debris, sparks, and loud noises.
Q: What is a title block on a construction drawing?
A feature that provides essential project details such as name, architect, date, and scale.
Q: How does the scale of a drawing affect construction?
It ensures that the dimensions on the drawing accurately represent the real-life measurements of the project.
