First-Aid Injury Frequency Rate (FAIFR) Calculator

What is First-Aid Injury Frequency Rate (FAIFR)?

First-Aid Injury Frequency Rate (FAIFR) is a workplace safety KPI that answers a simple question: How often do first-aid injuries occur? It measures the number of first-aid injuries relative to total manhours worked, normalized using a standard multiplier (commonly 1,000,000 hours).

FAIFR is especially useful for identifying minor injury patterns such as cuts, abrasions, splinters, small burns, and minor strains. These events are often early warning signs of unsafe conditions and unsafe acts.

The FAIFR formula is:

FAIFR = (Number of First-Aid Injuries × Multiplier) ÷ Manhours Worked

A high FAIFR indicates frequent minor injuries requiring first-aid treatment. While these cases may not be severe, they strongly indicate gaps in:

  • Housekeeping and workplace layout
  • Hand safety and tool usage
  • PPE compliance (gloves, safety shoes, eye protection)
  • Supervision and task planning
  • Reporting culture and unsafe act control

Important Notes (Before You Calculate)

  • First Aid vs Medical Treatment: FAIFR should include only cases classified as first-aid under your company definitions. Medical Treatment cases must not be included.
  • Upgrading cases: If a first-aid case later becomes a Medical Treatment Injury or Lost Time Injury, update the classification as per your procedure and exclude it from FAIFR for that period.
  • Reporting maturity: A very low FAIFR is not always “good” if near misses and safety observations are also very low (possible under-reporting).
  • Scope consistency: If contractors are included, ensure contractor manhours are included too for fair benchmarking.

Why Do We Use 1,000,000 / 200,000 / 100,000 Multipliers?

  • 1,000,000 hours is widely used internationally and in corporate reporting for benchmarking across sites.
  • 200,000 hours is commonly used in OSHA-style rate reporting (approx. 100 workers × 40 hrs/week × 50 weeks).
  • 100,000 hours can be practical for smaller sites/projects to avoid very small decimals.

Rule: Use the same multiplier consistently for trend comparison.

Tip: A rising FAIFR is often a leading signal for future recordable injuries if hazards are not controlled.

Worked Example: How to Calculate FAIFR

Assume your site recorded 24 first-aid injuries in a quarter and completed 1,200,000 manhours. Using a 1,000,000 multiplier:

FAIFR = (24 × 1,000,000) ÷ 1,200,000
FAIFR = 24,000,000 ÷ 1,200,000
FAIFR = 20.00

Result: Your FAIFR is 20.00 per 1,000,000 man-hours.

Why Tracking FAIFR is Important?

  • Minor injury trends: Highlights repeated low-level injuries that often share common root causes.
  • Early warning signal: Helps detect risk before escalation to Medical Treatment or Lost Time Injuries.
  • Improves reporting culture: Encourages prompt reporting and supports accurate first-aid inventory/usage control.
  • Targets preventive action: Useful for focused campaigns such as hand safety, slips/trips, and tool safety.

How to Reduce First-Aid Injury Frequency Rate?

  • Conduct frequent workplace inspections to remove unsafe conditions (sharp edges, clutter, poor access).
  • Improve PPE compliance (cut-resistant gloves, safety shoes, eye protection) based on task risk.
  • Strengthen toolbox talks and task briefings focusing on top first-aid injury types.
  • Encourage near-miss reporting and close unsafe condition actions quickly.
  • Review first-aid logs to identify repeating injury hotspots and implement controls.

Reducing minor injuries helps prevent major accidents, improves productivity, and boosts workforce confidence.

FAIFR FAQ

1) Is FAIFR a statutory KPI?
Not always. Many organizations track FAIFR as an internal KPI to detect early warning trends and strengthen safety culture.

2) What should be counted as first aid?
Use your company’s documented definitions. If a case becomes medical treatment or lost time, it should be reclassified and removed from FAIFR for reporting consistency.

3) Can a high FAIFR be a “good sign”?
Sometimes yes—higher reporting can indicate a healthy reporting culture. The key is whether corrective actions are reducing repeat events over time.

4) Which multiplier should we choose?
Follow your corporate standard. Consistency is the most important factor for trend comparison.
