PRESSURE CLEANER OPERATOR’S MANUAL
CLASSIFICATION
CLASSIFICATION
High Pressure Water Cleaning systems which include all BAR pressure cleaners are separated into two classes as per
Australian and New Zealand Standard 4233.1 & 2
Class A systems –Produce [pressure*flow] between 800 bar litres per minute and 5600 bar litres per minute.
Class B systems –Produce [pressure*flow] of 5600 bar litres per minute or greater.
A high pressure cleaning system cannot be reclassed by reducing available working pressure, the rating is based on
the units’ maximum output capability.
The following graph provided by Safe Work Australia can assist you to determine the class of your system.

Bar litres per minute = pressure (bar) x flow (L/min)
For example –
1000 psi gives 68.9 bar pressure from the conversion table and let’s say we want 60 L/min of flow. So if we follow the
graph, we can see that the lines meet in the green section which is class A and if we put the values into the formula
we get –
68.9 bar x 60 L/min = 4134 bar litres per minute
which justifies the system to be in the class A range as we witnessed from the graph.
Nozzle reaction force (newtons) = 0.182 x pressure (bar) x [x (nozzle diameter / 2)2(mm2)]
[Please refer to online catalogue page - 526 for nozzle diameter.]

RISK ASSESSMENT
Managing risks
Risk is the potential for injury or negative consequence based on the likelihood of a specific event occurring. Controls
must be put in place to eliminate the risk. Where the risk cannot be entirely eliminated, implement controls to reduce
risk by lowering the chance of the event occurring or minimising the severity of the consequence.
The risk matrix below can be used to provide a rank for any specific event.
