What Is the CITB HS&E Test?

The CITB Health, Safety & Environment test—often called the CSCS test—is a computer‑based assessment that proves you understand key construction site safety principles. Passing it is a prerequisite for most CSCS cards. You’ll face 50 multiple‑choice questions in 45 minutes covering:

  • General safety, health & environmental awareness
  • Working at height & manual handling
  • Fire prevention and emergency procedures
  • Occupational health (noise, dust, hazardous substances)
  • Legal duties and best practice for everyone on site

According to the CITB 2024 annual review, more than 650,000 HS&E tests were taken last year—up 8 % year‑on‑year, reflecting sustained growth in UK construction. Passing first time saves retest fees and speeds up card applications.

Show All Explanations
  1. CO2 extinguishers contain non‑conductive gas, making them safe for energized electrical equipment.
  2. PPE is effective only when intact and correctly fitted; damaged gear must be replaced immediately.
  3. The HSE GS6 guide recommends staying 3 m below 11 kV lines to avoid arcing.
  4. Blue signs denote mandatory actions such as “Wear safety helmet”.
  5. Combining plugs and earmuffs provides the highest SNR, often exceeding 35 dB.
  6. Site inductions tailor generic safety law to specific hazards, locations and emergency procedures you’ll face.
  7. Place the casualty in the recovery position to maintain their airway while help arrives.
  8. A lifting plan sets load weight, radius, sling angle and exclusion zones for safe crane work.
  9. Breathing respirable crystalline silica can scar lung tissue, causing silicosis.
  10. Damaged ladders fail the Workplace (Health, Safety & Welfare) Regulations; quarantine and report them.
  11. A quick visual check by users before each use picks up obvious cable or casing damage on power tools.
  12. A bump cap is designed for low‑risk overhead bumps, not impact from falling objects.
  13. Water mist suppresses dust at source and is the preferred engineering control.
  14. The employer/duty‑holder must organise six‑monthly thorough examinations under LOLER.
  15. HAVS damages blood vessels and nerves in fingers and hands, leading to numbness and pain.
  16. Red‑and‑white tape signals no entry—usually around excavations or drop zones.
  17. Store flammables in a fire‑resistant cabinet with ventilation and signage to BS EN 14470‑1.
  18. LOLER 1998 legally controls lifting equipment and operations in the UK.
  19. The control hierarchy starts with eliminating the hazard altogether.
  20. CDM welfare checks make sure minimum facilities (sanitary, rest, drinking water) are provided for all workers.
