The answer given would depend on the status of the injured person. Any of the information below could be utilised.

Responsible person

The 'responsible person' must notify, report and record the events (deaths, injuries and dangerous occurrences) which are covered by regulations 3 and 4 and the cases of disease covered by regulation 5.

Self-employed people

When a self-employed person is injured or suffers ill health at work, whether they or someone else must report depends on who was in control of the premises where they were working at the time the injury or case of ill health occurred.

For example, if a self-employed person is seriously injured while working for a firm of subcontractors on a large building site controlled by a main contractor, the main contractor must report the injury. However, if the injured self-employed person is working in their own premises, or in other premises under their control at the time of the accident, they must report the injury.

Under RIDDOR there is no requirement on anyone to report the death of a self-employed person which occurs in premises where they are the owner or occupier (regulation 10 (5)).

Major injury, over-3-day injury, or case of disease of a self-employed person at work in premises under their - The self-employed person or someone control acting on their behalf

DANGEROUS OCCURRENCES

One of the dangerous occurrences listed in Schedule 2 to the Regulations - The person in control of the premises sat the time the dangerous occurrence happened: and in connection with their carrying on any trade, business or undertaking, except: 

-where, they occur at workplaces covered by part I of this table (ie at mines, quarries, closed mine or quarry tips, offshore installations or connected with diving operations); or 

· These: 

A dangerous occurrence at a well - the concession owner or the person appointed by the concession owner to organise or supervise any operation carried out by the well

A dangerous occurrence at a pipeline - The owner of the pipeline

A dangerous occurrence involving a dangerous substance being conveyed by road - The operator of the vehicle

Mobile employees

A reportable injury to a mobile employee, sometimes referred to as a peripatetic employee, (for example, a goods or postal delivery worker, a refuse collector, a sales representative, community health nurse, a building worker who travels from site to site, social worker or a service engineer) must be reported by that person's employer, wherever the accident causing the injury happens. For example, if a mobile refrigeration engineer is seriously injured while working in a supermarket, the engineer's employer must make the report, not the operator of the supermarket. The report must be made to the local office of the relevant enforcing authority for the premises where, or in connection with the work at which, the injury occurred. Where a workplace is shared, co-operation between employers and self-employed people is required by regulation 9 of the Management of Health and Safety at Work Regulations 1999. For that reason, an employer in control of premises where there is a reportable accident involving a mobile employee working away from their base should inform that person's employer about it as soon as possible.
