Industrial laser accidents are rare but can cause severe burns. This case details a 1.5 KW laser injury to an index finger, resulting in a deep wound and temporary nerve issues, which healed without functional loss.

Area of Science:

  • Occupational safety
  • Laser technology
  • Dermatology

Background:

  • Accidental laser injuries are uncommon, with ocular injuries being most frequent.
  • Industrial lasers, particularly high-power invisible beams, pose significant risks.

Observation:

  • An industrial worker sustained a 1.5 KW invisible laserbeam injury to the right index finger.
  • The resulting lesion was a deep cavity (3 x 3 x 12 mm) affecting the dermis and subcutaneous tissue.
  • Temporary ulnar nerve involvement was noted.

Findings:

  • The laser-induced wound healed within 10 days.
  • Healing resulted in a linear scar without loss of finger function.
  • The severity of the injury highlights the need for enhanced safety protocols.

Implications:

  • Visible frequency addition to cutting laser systems could improve safety.
  • This case underscores the importance of comprehensive safety measures in industrial laser applications.
  • Further research into laser safety for non-ocular industrial injuries is warranted.
