 1. PCB equipment has to be used with great care. Health and safety is important at every stage of producing a PCB (printed circuit board). Look carefully at the equipment shown below and list two safety rules for each one.

 

ETCHING TANK
 
RULE 1:
 
RULE 2:
 
  POSSIBLE ANSWER
   
 
ETCHING TANK
 
RULE 1: Use plastic tongs to place pcb into tank. Do not use hands / fingers as the chemicals are dangerous.
 

RULE 2: Wear goggles/visor and appropriate safety clothing when placing pcb in the tank and also when removing it. Chemicals are dangerous if ‘splashed’ on to the user.

 
   

PCB DRILL
 
RULE 1:
 
RULE 2:
 
     
 
PCB DRILL
 

RULE 1: Ensure that the PCB is clamped / held securely so that the drill does not ‘spin’ it round causing an accident to hands / fingers.

 

RULE 2: Wear goggles when drilling in case the PCB shatters or pieces are thrown off into the face.

 
 
   

SOLDERING IRON
 
RULE 1:
 
RULE 2:
 
 

POSSIBLE ANSWER

   
 
SOLDERING IRON
 

RULE 1: Check the condition of the electrical cord. A damaged cord can lead is highly dangerous, especially if the soldering iron is rated at 240 volts

 

RULE 2: Ensure the PCB is held securely and not in the hand. Soldering iron tips are extremely hot

 
   

SAFETY GOGGLES
 
RULE 1:
 
RULE 2:
 
   
   
 
SAFETY GOGGLES
 

RULE 1: Wear safety goggles when drilling or at anytime the eyes are in danger. For example, soldering or using the brazing hearth.

 

RULE 2: Wear the correct standard goggles for the process. A British Standards code is stamped on every pair of goggles. This determines for which process the goggles are suitable.
