care.  Protect them from damage by people, 
objects  and  vehicles.    Never  lay  them  in 
dirt,  mud,  ice  or  other  loose  material  which 
could plug the fluid opening or interfere with 
their  operation.    Never  use  the  wand, 
nozzle,  gun,  etc.  to  pry  loose  material  off 
items being cleaned. 
 
Before 

starting 

operation 

in 

cold 

environment,  check  to  make  sure  there  is 
no  ice  in  the  fluid  system  and  repeat  this 
inspection  each  time  before  operation  is 
restarted. 
 
Before  purchasing  wands,  nozzles,  guns, 
connections,  hoses,  etc.,  manufacturers  of 
these  components  should  be  contacted  for 
detailed  information  on  the  design  and 
safety 

features 

incorporated 

in 

their 

products.    After  careful  study  of  various 
manufacturers  products,  we  recommend 
that  only  those  wands,  nozzles,  guns, 
connections  and  hose,  etc.,  be  considered 
for  purchase  that  you  judge  to  offer  the 
highest  quality  of  design,  construction  and 
safety,  since  these  components  are  among 
the  most  critical  to  the  safe  operation  of 
high  pressure  liquid  jetting,  blasting  and 
cleaning equipment. 
 
After  you  have  selected  and  purchased 
these 

components, 

follow 

the 

manufacturer’s  instructions  completely  in 
their use. 
 
In  summary,  high  pressure  jetting, 
blasting  and  cleaning  are  inherently 
dangerous,  as  the  pressures  and  flow 
rates needed to remove scale, clean, etc. 
are  sufficient  to  cause  personal  injury, 
death, 

and/or 

equipment 

damage 

resulting  from,  but  not  limited  to, any of 
the  conditions  described  in  the  above 
Danger Notices.
