Safety

Media

  1. A respirator (N95 minimum) and safety glasses shall be worn whenever handling, sieving or applying either test medium. A P100 respirator should be used.
  2. Sand shall be sieved and agitated outdoors or with strong ventilation. This applies to all sand, including “washed” play sand.
  3. Silica flour, ground glass and other fine abrasive powders shall not be used in the home kit.

Note (informative): Sand contains crystalline silica. Sieving and agitating it releases respirable silica dust, which causes silicosis.

UV light

  1. The UV flashlight shall not be shone into anyone’s eyes.
  2. Safety glasses worn under UV light should be UV-rated.

Device

  1. The unit shall be backed up before testing.
  2. If the unit becomes hot, swells, smells or smokes, testing shall stop immediately and the unit shall be moved outdoors onto a non-flammable surface.
  3. The unit shall not be charged during exposure. After water exposure, it shall not be charged until the drying period [TBD] has passed.

Note (informative): Charging through a wet port can corrode its contacts or short the device.

Note (informative): For home testers, the procedure aims to keep the device working, but there is no guarantee. Some debris may stay in the device permanently, and deliberately contaminating a device may void its warranty.

Pressure vessels

  1. A pressure vessel used for W shall be rated for the pressure applied.
