Which incidents, and who investigates
Serious injuries and deaths, major structural failures or collapses, major releases of a hazardous substance, and fires or explosions that could seriously injure a worker are reported to WorkSafeBC immediately, and the scene is left alone except to help the injured, prevent more harm or protect property.
Those incidents, any injury needing medical treatment, and any near miss that could have caused serious injury are investigated twice: a preliminary and a full investigation. Vehicle accidents on public roads are excluded. The investigators know the work, and the employer and a worker representative take part where reasonably available. Witnesses are made available, and their contact details are recorded.
The preliminary report: within 48 hours
The preliminary investigation starts immediately and its report is done within 48 hours. As far as possible it gives the place, date and time; the names and job titles of the injured, the witnesses and the investigators; the sequence of events; the unsafe conditions, acts or procedures that contributed; the employer's details; a brief description; the interim corrective actions, which ones are done and when the rest will be; and anything that stopped an element from being covered.
The report goes to the joint committee or worker health and safety representative as soon as practicable, or is posted at the workplace, and to WorkSafeBC if asked. Interim fixes are made without undue delay, with a short report of the action taken.
The full report: within 30 days
The full investigation finds the underlying causes, such as gaps in supervision, training, maintenance or procedures, and the corrective actions to prevent a repeat. Its report adds the employer's legal and business names, address, phone, email and WorkSafeBC account number, the other workplace parties, a full description, everyone who took part, and every corrective action with when it was or will be done.
It goes to WorkSafeBC within 30 days of the incident, unless WorkSafeBC extends that, and to the joint committee or worker representative, or is posted, within the same 30 days. Employers and supervisors must never discourage a worker from reporting an injury or claiming compensation.
From notes to a B.C. investigation report
Note who was there, their job titles, what happened in order, and what you changed right away. ReportDraft adds the employer's WorkSafeBC details and the investigators to the header, marks the report as preliminary or full, lists contributing unsafe conditions as findings, keeps witnesses' home contact details out, records each corrective action with an owner and a date, and notes anything the investigation could not cover yet.
Common mistakes
- Missing the 48-hour deadline for the preliminary report.
- Leaving out the job titles of the injured worker, witnesses or investigators.
- Investigating without a worker representative when one was reasonably available.
- Stopping at the unsafe act and never finding the underlying cause.
- Not sharing the report with the joint committee or worker representative, or not posting it.
