A3: Laser Plume

Question 1

What is laser plume?

Answer 1

Collection of fine particles varying in size, which disperse in the air during laser treatments, (due to targeting chromophore and thermal reaction) and thermally alter target tissues

Question 2

What are the general health effects associated with laser plume generation

Answer 2

• Acute and chronic respiratory disorder
  E,g. Asthma, acute and chronic bronchitis (lungs inflamed and mucous) and pneumonia (lung infection
• Throat irritation and pain
• Eye irritation

Question 3

Serious health effects associated with laser plume generation?

Answer 3

• Allergic sensitisation
• Viral wart in respiratory tract
• HIV & HPV infection
• Hepatitis
• Cancer: Respiratory, lymphatic and blood related

Question 4

How can you appropriately control this hazard in clinical setting?

Answer 4

Engineer controls:
- Evacuate plume by Local Exhaust Ventilation (LEV): Extract laser plume through a filter (HEPA or ULPA) to remove the particulate matter, ULPA (ultra low penetration air filter) filter small particles (0.1μm),
Activated charcoal filter: minimise odour of plume

Administrative control:
- Work role rotations: reduce plume exposure
- Training and acknowledgment of PPE
Health ad safety risk training

PPE control:
- Personal Protective Equipment
Particulate filter respirators
