Risk Assessment & Hazard Management Flashcards

Why does SPRAT require two independently anchored systems (a working line and a safety line)?

Answer: So that a single failure does not cause a fall

Redundancy means that if one system fails, the independent backup still prevents a fall.

A worker hanging motionless in a harness after a fall is at risk of which time-critical condition?

Answer: Suspension intolerance (suspension trauma)

Motionless suspension lets blood pool in the legs, which can cause loss of consciousness and death, so rescue must be prompt.

Which control is an example of an ADMINISTRATIVE control?

Answer: A written work permit and job hazard analysis

Administrative controls change how the work is done through procedures, permits, training, and scheduling.

Before starting work near overhead power lines, what is the PRIMARY step in hazard management?

Answer: Identify the voltage and maintain the required minimum approach distance or de-energize

OSHA requires keeping minimum clearances (at least 10 ft for lines up to 50 kV) or de-energizing and grounding the lines.

Who on a rope access team is normally responsible for overall site safety and the risk assessment?

Answer: The SPRAT Level III supervisor

SPRAT places responsibility for site safety, work planning, and rescue on the Level III.

Which practice BEST controls dropped-object hazards from technicians on rope?

Answer: Tethering tools and equipment with rated lanyards

Tethering tools stops them falling at the source, which works better than relying only on people below.

Conditions on site change during a job, such as rising wind. What should the team do?

Answer: Reassess the risk dynamically and adjust or stop work

Risk assessment is continuous, and new hazards require on-the-spot reassessment and updated controls.
