Incident Investigation and Reporting Requirements#

Executive Summary#

When workplace incidents occur—injuries, illnesses, near-misses, or property damage—employers should investigate to determine causes and prevent recurrence. Certain incidents must be reported to OSHA within specified timeframes. Understanding investigation processes and reporting requirements helps ICI contractors respond appropriately to incidents while meeting regulatory obligations.

The Context for ICI Subcontractors#

Construction is a high-hazard industry. Despite safety efforts, incidents occur. The response to incidents matters: proper investigation identifies causes and prevents recurrence, while proper reporting meets legal obligations.

Both under-response (failing to investigate or report) and over-response (excessive documentation creating liability) carry risks. Understanding what is required enables appropriate response to workplace incidents.

Types of Incidents#

Injuries#

Physical harm to workers:

First aid cases: Minor injuries requiring only first aid treatment
Recordable injuries: More serious injuries requiring medical treatment beyond first aid
Lost time injuries: Injuries causing workers to miss work
Fatalities: Worker deaths

Illnesses#

Occupational diseases and health conditions:

Respiratory conditions from dust or fiber exposure
Skin conditions from chemical contact
Hearing loss from noise exposure
Musculoskeletal disorders from repetitive activities

Near-Misses#

Events that could have caused injury but did not:

Falling objects that miss workers
Equipment failures that do not result in injury
Situations where injury was narrowly avoided

Property Damage#

Damage to equipment, materials, or property without personal injury.

OSHA Reporting Requirements#

What Must Be Reported to OSHA#

Certain incidents require direct notification to OSHA:

Within 8 hours: Report all work-related fatalities

Within 24 hours: Report all work-related:

Inpatient hospitalizations (one or more workers)
Amputations
Loss of an eye

How to Report#

Report to OSHA by:

Calling OSHA's toll-free number: 1-800-321-OSHA (1-800-321-6742)
Calling or visiting the nearest OSHA area office
Using OSHA's online reporting system

What to Report#

When reporting, provide:

Establishment name
Location of incident
Time of incident
Number of fatalities or hospitalized employees
Names of affected employees
Contact person and phone number
Brief description of incident

Exceptions#

Some incidents are not reportable:

Motor vehicle accidents on public streets (except in construction work zones)
Incidents on commercial aircraft, trains, subways, buses
Hospitalization for diagnostic testing or observation only

OSHA Recordkeeping#

300 Log#

Employers with more than 10 employees must maintain OSHA Form 300 (Log of Work-Related Injuries and Illnesses) recording:

Recordable injuries and illnesses
Whether days away from work, job transfer, or restriction
Type of injury or illness

301 Form#

For each recordable case, complete Form 301 (Injury and Illness Incident Report) or equivalent documenting details of the incident.

300A Summary#

Post the annual summary (Form 300A) from February 1 through April 30 each year.

Recordable vs. Non-Recordable#

An injury or illness is recordable if it results in:

Death
Days away from work
Restricted work or transfer
Medical treatment beyond first aid
Loss of consciousness
Significant injury or illness diagnosed by physician

First aid only cases are generally not recordable.

Incident Investigation#

Purpose of Investigation#

Investigation serves to:

Determine what happened
Identify root causes
Prevent similar incidents
Document findings
Meet regulatory and company requirements

Investigation is not about assigning blame but about understanding causes to prevent recurrence.

When to Investigate#

Investigate:

All recordable injuries and illnesses
Significant near-misses
Property damage incidents
Any incident that could have resulted in serious injury

The scope of investigation may vary with incident severity.

Investigation Process#

Immediate response: Ensure injured workers receive care, secure the scene, preserve evidence.

Gather information:

Interview witnesses and those involved
Photograph the scene
Document equipment and conditions
Collect relevant documents (procedures, training records)
Diagram the incident area

Analyze causes:

What happened? (Sequence of events)
Why did it happen? (Contributing factors)
Root causes? (Underlying conditions or systems that allowed contributing factors)

Develop corrective actions:

What changes will prevent recurrence?
Who is responsible for implementation?
What is the timeline?

Document findings:

Written report of investigation
Conclusions about causes
Corrective action plans

Follow up:

Verify corrective actions are implemented
Monitor effectiveness
Share lessons learned

Root Cause Analysis#

Effective investigation goes beyond immediate causes to root causes:

Immediate cause: Worker slipped on wet surface

Contributing factors: Water on floor from leak, inadequate lighting, worker in hurry

Root causes: Maintenance procedure did not address leak promptly, lighting standards not enforced, schedule pressure from production demands

Addressing root causes prevents not just the specific incident but similar incidents from related causes.

Interview Techniques#

Effective witness interviews:

Interview promptly while memory is fresh
Interview separately to get independent accounts
Ask open-ended questions
Do not lead witnesses toward conclusions
Focus on facts, not blame
Document what witnesses say

Documentation#

Investigation documentation should include:

Date, time, location of incident
Description of what happened
Names of those involved and witnesses
Injuries or damage that resulted
Photos and diagrams
Interview summaries
Analysis of causes
Corrective actions identified
Signatures and dates

Near-Miss Reporting#

Value of Near-Miss Reporting#

Near-misses provide valuable safety information:

Indicate hazards that could cause future injuries
Occur more frequently than actual injuries
Allow correction before injury occurs

Encouraging Reporting#

Build a culture that encourages near-miss reporting:

No-blame approach to reporting
Easy reporting mechanisms
Visible response to reports
Recognition for reporting

Investigating Near-Misses#

Investigate near-misses using same approach as injury investigations:

What happened?
What prevented injury?
What could make injury more likely in future?
What corrective actions are needed?

Canadian Requirements#

Provincial Variation#

Canadian incident reporting is regulated provincially. Requirements vary but typically include:

Reporting serious injuries, fatalities, and dangerous occurrences to provincial ministry
Maintaining incident records
Investigating workplace incidents

Check specific provincial requirements where work is performed.

WSIB/Workers' Compensation#

Work-related injuries typically require reporting to provincial workers' compensation boards (WSIB in Ontario, WorkSafeBC, etc.) within specified timeframes.

Documentation Retention#

Retention Periods#

Maintain incident records:

OSHA 300 logs: 5 years following the year they pertain to
Investigation reports: Retain per company policy and legal requirements
Training records: Per applicable standards

Accessibility#

Records must be accessible:

Available for OSHA inspection
Available to employees for their own records
Available to employee representatives for 300 log review

Legal Considerations#

Privilege and Confidentiality#

Some investigation information may be sensitive:

Medical information has privacy protections
Some communications may be privileged
Documentation may be discoverable in litigation

Consult legal counsel about documentation practices that protect appropriate confidentiality while meeting requirements.

Consistency#

Apply investigation processes consistently:

Investigate similar incidents similarly
Document comparably across incidents
Follow established procedures

Inconsistency can create legal exposure.

How Appello Supports Incident Documentation#

Appello's Safety & Forms module enables documentation of incidents through configurable forms. Incident reports can be completed on mobile devices at the time of occurrence, capturing details while fresh.

The system maintains records of safety documentation, supporting the recordkeeping requirements of safety programs.

Conclusion#

Incident investigation and reporting are essential responses to workplace incidents. Investigation identifies causes and prevents recurrence. Reporting meets legal obligations to regulatory agencies.

ICI contractors should understand OSHA reporting requirements, implement consistent investigation processes, and maintain appropriate documentation. The goal is not just compliance but learning from incidents to prevent future harm.
