June 2013: If you want to keep on producing high-quality products, don’t neglect observation processes, says our senior technical advisor Gareth Jantjies.
Your operators should check every batch of timber before treating it and take a sample after each batch is treated, he advises.
The “pre-observation” process entails using a moisture metre to check that the moisture content of the wood is appropriate for its purpose, and “post-observation” requires taking samples to check there was sufficient penetration of the chemical.
These checks are required by SANS 10005 and 1288.
They will also safeguard you against possible future claims from customers that your wood was not properly preserved, Gareth says.
“Many operators stop doing pre- and post-observations, in the same way that most drivers do not always check their cars before getting in to drive, despite being taught this when they were learners,” says Gareth.
“But observation is crucial for protecting and promoting your business. Make sure your operators always do the observations, and put checks in place to make sure this is happening,” he advises.
