An IT technician is tasked with cleaning up a substantial dry toner spill inside a high-volume departmental laser printer room. Place the following safety and cleanup steps in the correct chronological order from first to last.
- 1Disconnect power from the laser printer and allow internal heating elements to cool.
- 2Don personal protective equipment (PPE), including safety goggles and a particle dust mask.
- 3Use a specialized ESD-safe vacuum equipped with a high-efficiency particulate air (HEPA) filter to remove the loose toner powder.
- 4Wipe residual toner particles off non-electrical surfaces using a cold, damp cloth.
- 5Dispose of collected toner waste and cleanup materials according to the Safety Data Sheet (SDS) and local regulations.
Answer
The proper sequence begins with disconnecting power to eliminate electrical and thermal hazards, followed by donning PPE (goggles and particle mask). Next, a specialized ESD-safe toner vacuum with a HEPA filter is used to extract loose powder. Residual particles are then wiped away using a cold, damp cloth. Finally, all waste is disposed of in accordance with SDS guidelines.
The correct sequence ensures personal safety and equipment integrity. First, disconnecting power prevents shock and thermal injuries. Second, putting on PPE protects against particle inhalation. Third, using an ESD-safe HEPA vacuum safely removes the bulk toner without causing static discharge or recirculating fine dust. Fourth, cold water on a damp cloth lifts remaining residue without fusing the toner powder. Finally, disposing of materials following SDS documentation ensures regulatory compliance.
