Code 1470 applies to employers engaged in wood distillation plants utilizing steam or destructive distillation processes to produce alcohol-based products.  In both cases, cord wood is purchased cut to size.  In steam distillation plants, it is necessary to grind the wood to produce chips to enable the steam to thoroughly saturate the wood being processed.  In the destructive distillation process, which is comparable to charcoal manufacturing, cord wood is simply placed on steel carts and pushed into retorts.  The distillation of pine wood, by either method, to produce turpentine and various by-products such as pinene and camphine is also included under this classification.  After the wood has been relieved of all its turpentine, it is allowed to cool in an airtight container to prevent oxidation and is either then sold as charcoal or ground up as chicken feed.  This process is also known as the retort method and is substantially the standard method also followed in producing other wood by-products such as wood alcohol and acetic acid, which are joint products of the destructive distillation of certain hard woods.  The manufacturing of creosote from wood is also covered under this classification.

Coke manufacturing using beehive or by-product oven methods is also assigned to this classification.
