CITB Managers Accident Investigation and RIDDOR 3

Question 1

What is the 'fault tree analysis' technique used in accident investigation?

Accepted Answer

A top-down systematic technique that starts with the accident (top event) and works backwards through possible causes, identifying contributing factors and logical relationships

Answer

Fault tree analysis (FTA) is a top-down deductive technique starting from the accident event and working backwards to identify all possible contributing causes. It uses logic gates (AND/OR) to map the causal chain and can identify multiple simultaneous causal paths.

Question 2

A RIDDOR report for an over-7-day incapacitating injury must be submitted to the HSE. The 7 days is calculated as:

Accepted Answer

7 consecutive days (including non-working days, but not the day of the accident) during which the worker is unable to carry out their normal range of work duties

Answer

The 7-day period begins the day after the accident and includes all days — working and non-working — during which the worker is incapacitated from their normal work. If the worker is still incapacitated after 7 consecutive days, the injury must be reported within 15 days of the accident.

Question 3

An 'occupational disease' must be reported under RIDDOR when:

Accepted Answer

A doctor notifies the employer that a worker is suffering from a RIDDOR-listed occupational disease (such as carpal tunnel syndrome, occupational dermatitis, HAVS) and the work involves the associated activity

Answer

Occupational diseases listed in RIDDOR Schedule 3 must be reported when a diagnosis is made by a doctor and the work involves the listed causative activity. Examples include hand-arm vibration syndrome (HAVS), carpal tunnel syndrome from use of vibrating tools, and occupational dermatitis from skin contaminants.

Question 4

What is the role of the site manager in an accident investigation?

Accepted Answer

To ensure the scene is preserved, first aid and emergency services are called, relevant information and witnesses are identified, and the investigation process is initiated

Answer

The site manager's immediate duties after an accident: secure the scene, ensure first aid/emergency services, prevent disturbance of the scene until investigated, identify witnesses, gather initial information, and initiate the investigation process in accordance with the company's procedure.

Question 5

Following an accident investigation, recommendations must be:

Accepted Answer

Specific, actionable, assigned to named individuals with target completion dates, and followed up to confirm they have been implemented effectively

Answer

Recommendations from accident investigations must be SMART — specific, assigned to named responsible persons, with target completion dates. Follow-up must confirm effective implementation. Generic or unassigned recommendations that are never followed up fail to prevent recurrence.
