I think Wood breakage policy is enough if you have. What we are doing in our compnay is we documented on policy related to foregien Object control policy and we have mentioned some point
1. Only heat treated and approved pallets will be used
2. All the pallet will be checked for the integrity and abnormility at the the time of receving at plant. Security gurad is responsible to take care of this point also same will be verified by the Dy. manager Systems and audit.
3. pallets are made of good wood and not un even finishing.
4. we have defined a frequency of life of these pallets. Every 6 month we chane the pallets with new one.
6. Monitoring is being carried out on monthly basis of all the pallets.
7. Also treatment is carried out for wood borer.
I think these point can be added in the procedure
And please if anybode have something better realted to this , i will really appriciate...
