  1. High-pressure hydraulic injection hazard.
  2. Ionizing radiation hazard.
  3. Entanglement hazard (缠绕危险). Correct answer.
  4. Laser beam eye-damage hazard.

Explanation

Rotating shafts, protruding set screws, smooth revolving cylinders, and exposed couplings present severe entanglement hazards (缠绕危险) where loose clothing, hair, or gloves can be seized and wrapped around the rotating shaft, causing catastrophic crushing or amputation injuries.

Question 9Machine, electrical and process hazard mechanisms

Which design approach represents an 'Inherently Safe Design Measure' (本质安全设计措施) for machinery under GB/T 15706?

  1. Attaching a paper warning label instructing operators to be extra cautious around exposed gears.
  2. Issuing leather gloves to workers operating rotating spindle drill presses.
  3. Relying solely on disciplinary fines to stop workers from touching operating belt drives.
  4. Eliminating pinch points by increasing clearances, using rounded corners, reducing moving mass/velocity, and designing fail-safe mechanisms. Correct answer.

Explanation

Inherently safe design (本质安全) is the first and most effective step in the risk reduction hierarchy. It eliminates hazards or reduces risks by changing the machine's physical design itself (e.g., safe geometry, limiting actuating forces and speeds, eliminating sharp edges, self-limiting energy) without relying on external guards, warning signs, or PPE.

Question 10Machine, electrical and process hazard mechanisms

In a properly designed interlocked guarding arrangement whose actual stopping and access conditions have been assessed, which listed principle links the guard with hazardous machine functions?

  1. The hazardous machine functions cannot operate until the guard is closed, and opening the guard while the machine is running initiates a stop command before hazard exposure can occur. Correct answer.
  2. The guard remains permanently welded in place and requires cutting torches to remove.
  3. The guard opens automatically whenever the machine experiences an electrical short circuit.
  4. The guard is completely transparent but provides no electrical or mechanical connection to the motor starter.

Explanation

The interlock prevents the defined hazardous functions with the guard open and initiates the assessed stop response when it opens. Actual stopping time and access distance matter; guard locking or other measures can be needed if danger persists. The device is not energy isolation and guard closure must not itself justify an unexpected hazardous restart.

Question 11Construction responsibilities, temporary works and changing sites
