Risk assessments

Risk assessment: UV light source

Group/location:

Security Group, Tamper Lab, SE09

Description of activity/workplace:

Novacure UV light source, 20 W/cm², 250–450 nm

Identified hazards:

  1. source of ionising UV radiation
  2. very hot lamp
  3. high-voltage power supply

Whom those hazards affect:

Sergei Skorobogatov (supervisor: Ross Anderson)
Markus Kuhn

Reasonably foreseeable outcome:

  1. eye or skin damage
  2. burn or fire
  3. electrocution

Safe working procedure:

The UV light source is not used at present, therefore this risk assessment is only a first draft.

  • never look into light emitting end of the light guide
  • never expose skin to UV light
  • remove AC power cord before removing the cover
  • use laser safety goggles that absorb emitted band (250-450 nm)
  • ask people without safety goggles to leave SE09 during experiments
  • device design prevents operation with opened arc lamp drawer
  • wait for lamp to cool down before opening lamp drawer
  • do not operate unattended over long periods of time
