| Minor Burns due to accidental skin contact with the oven interior.
|
The reflow oven will not stay on for more than two minutes, and should cool down fairly quickly after use due to extraction. The oven interior is only accessible by opening a drawer, so accidentally touching something hot by being near it is unlikely to be an issue. While the oven does not require an induction, there will be training offered and there is a notice posted on the machine pointing to instructions on the wiki.
|
3/3
|
People in the area might be unaware of how hot the oven may be.
|
Put hot warning sticker on the oven.

|
| Electrical Shock due to damaged cabling or poor earthing.
|
Portable Appliance Testing (PAT) is performed according to a schedule. A visual inspection of the appliance should take place prior to use of a soldering iron.

| Fire due to an unattended use.
|
There is a notice posted indicating that the machine must not be left unattended. The machine will run for a maximum of eight minutes, at which point it will begin to cool down. The internals of the oven are enclosed in stainless steel, with a fire proof insulation around that. Fire is therefore unlikely.

| Fumes due to flux evaporating
|
The oven is attached to the Electronics Extraction. There is a notice on the machine informing the user that this must be turned on before use. The extraction vents outside.

| Hazardous Substances e.g. solder paste.
|
Solder paste comes in containers with appropriate warnings about ingestion, as well as recommendations for PPE. PPE is available in the Electronics Area (namely, safety glasses and gloves).
