CSCS Health and Welfare 3 — Questions and Answers
Question 1: What is the main risk of workers not having access to adequate washing facilities on a construction site?
- Workers may feel uncomfortable but there is no real risk
- Harmful substances like cement or lead can be ingested or absorbed through the skin (Correct answer)
- Workers will spend less time on breaks
- Tools may become contaminated
Correct answer: Harmful substances like cement or lead can be ingested or absorbed through the skin
Without proper washing facilities, hazardous substances can be transferred from hands to mouth or absorbed, causing serious health issues.
Question 2: Which of the following is a common long-term health risk associated with working in the construction industry?
- Improved cardiovascular fitness from physical labor
- Noise-induced hearing loss from prolonged exposure to loud machinery (Correct answer)
- Better eyesight from working outdoors
- Increased immunity from outdoor exposure
Correct answer: Noise-induced hearing loss from prolonged exposure to loud machinery
Chronic exposure to high noise levels without hearing protection leads to permanent, irreversible hearing loss.
Question 3: What should a worker do if they suspect they have been exposed to asbestos on a construction site?
- Continue working and report at the end of the day
- Stop work immediately, leave the area, and report to a supervisor (Correct answer)
- Brush off any dust and use a face mask to continue
- Seal the area with tape and carry on with adjacent tasks
Correct answer: Stop work immediately, leave the area, and report to a supervisor
Asbestos exposure is a serious health emergency requiring immediate work stoppage and reporting to prevent inhalation of dangerous fibers.
Question 4: Why is it important for construction workers to take regular breaks away from noisy environments?
- Breaks are required by union agreements only
- To allow the ears to recover and reduce the cumulative risk of hearing damage (Correct answer)
- Breaks have no impact on noise-related health outcomes
- To reduce electricity usage from machinery
Correct answer: To allow the ears to recover and reduce the cumulative risk of hearing damage
Regular breaks in quiet areas reduce the total daily noise dose, helping protect hearing over the long term.
Question 5: What is 'whole-body vibration' (WBV) and how does it affect construction workers?
- A massage therapy used to relieve muscle pain
- Vibration transmitted through the seat or feet from vehicles or machinery, which can damage the spine (Correct answer)
- A breathing exercise to improve lung capacity
- A safety inspection method for heavy equipment
Correct answer: Vibration transmitted through the seat or feet from vehicles or machinery, which can damage the spine
WBV from operating heavy plant or vehicles over time can cause back pain, spinal damage, and other musculoskeletal disorders.
Question 6: Which group is at highest risk of developing occupational asthma on a construction site?
- Workers who perform only administrative tasks
- Workers regularly exposed to dust, fumes, or chemicals such as isocyanates or wood dust (Correct answer)
- Workers who operate cranes at height
- Night-shift security personnel
Correct answer: Workers regularly exposed to dust, fumes, or chemicals such as isocyanates or wood dust
Repeated inhalation of sensitizing substances like dust or chemical fumes can trigger occupational asthma, a serious and often permanent condition.
Question 7: How should a worker store and handle their work clothes to reduce the risk of taking hazardous substances home?
- Bring contaminated clothing home to wash with the family laundry
- Change out of work clothes on site and store them separately from personal clothing (Correct answer)
- Leave all clothing at home and buy disposable coveralls
- Wear work clothes until the end of the week, then wash them once
Correct answer: Change out of work clothes on site and store them separately from personal clothing
Keeping work clothes separate prevents transferring construction contaminants to family members or the home environment.
