SIMMONS, logging specialist NORTHEASTERN FOREST EXPERIMENT STATION FOREST SERVICE UNITED STATES GOVERNMENT PRINTING OFFICE - - - WASHINGTON, D. C, 1951 For sale by the Superintendent of Documents, Washington, D. C. Price 75 cents Preface THOSE who want to be successful in any line of work or business must learn the tricks of the trade one way or another. For most occupations there is a wealth of published information that explains how the job can best be done without taking too many knocks in the hard school of experience. For logging, however, there has been no ade- quate source of information that could be understood and used by the man who actually does the work in the woods. This NORTHEASTERN LOGGERS' HANDBOOK brings to- gether what the young or inexperienced woodsman needs to know about the care and use of logging tools and about the best of the old and new devices and techniques for logging under the conditions existing in the northeastern part of the United States. Emphasis has been given to the matter of workers' safety because the accident rate in logging is much higher than it should be. Sections of the handbook have previously been circulated in a pre- liminary edition. Scores of suggestions have been made to the author by logging operators, equipment manufacturers, and professional forest- ers.

  • MPAC Market Valuation Report Sawmills
    ASSESSMENT METHODOLOGY GUIDE ASSESSING SAWMILLS IN ONTARIO 2016 BASE YEAR APRIL 2015 This document describes the assessment methodology that MPAC currently expects to use for the 2016 Assessment Update for properties for which the current use is as a sawmill and for which the current use has been determined by MPAC to be the highest and best use. Assessors exercise judgment and discretion when assessing properties and may depart from MPAC’s preferred assessment methodology when assessing a particular property, however, any deviation from these guidelines must be thoroughly documented. This document has been prepared by MPAC to help assessed persons review how the current value of the property likely will be determined, illustrate the uniform application of valuation parameters to the property type and consider whether MPAC’s subsequent assessed value is correct and equitable in comparison to the assessed value of similar real property so as to ensure the fair distribution of the property tax burden. The information in this document will help property owners to meet the requirements of subsection 39.1(4) of the Assessment Act and Rule 16 of the Assessment Review Board when providing reasons for making a Request for Reconsideration or filing an Appeal to the Assessment Review Board. © Municipal Property Assessment Corporation 2015 All rights reserved April 30, 2015 In accordance with the direction issued by the Minister of Finance on April 18, 2015, pursuant to subsection 10(1) of the Municipal Property Assessment Corporation Act, the Municipal Property Assessment Corporation (MPAC) has published Assessment Methodology Guides for the following industries: • Pulp and Paper Mills; • Saw Mills; • Value-Added Wood Products Manufacturing Plants; • Steel Manufacturing Plants; • Automotive Assembly Plants; • Automotive Parts Manufacturing Plants.

    Portable Milling Reference Guide v1.1 Created by Ian Hanna, Northwest Natural Resource Group Phone:360-379-9421, Email:[email protected], Web: www.nnrg.org This reference guide is intended to educate new mill owners on the full spectrum of issues related to onsite milling, primarily with bandmills. The guide does not cover basic milling techniques or specific operating and maintenance procedures, which are typically included in manufacturer trainings and manuals. Last updated August 2007 - 1 - Note: See Glossary on last page for definitions 1. Safety Clearly, safety is the main concern in all aspects of mill operation. There are many hazards and the risk of severe or fatal injury is very real. Understanding the potential for these risks and planning for their prevention is critical to a safe working environment. 1.1. Safety equipment – Generally, safety equipment will be very similar to that required for felling or other chainsaw work. As a chainsaw is often used to prepare or modify logs going onto the mill, it’s a good idea to dress for both. Essential clothing includes: Hard hat Safety glasses (not just a helmet screen) Headphones (not earplugs) Tight fitting gloves (rubber coated cotton recommended) Heavy leather boots (steel toe optional) Heavy pants (chaps if operating a chainsaw) Heavy leather gloves (for changing and coiling blades) Comprehensive first aid kit, including eye wash Mobile phone or other communication device Passenger vehicle for emergency evacuation 1.2. Cutting risks – Never put hands, feet, foreign material, or any other object near the cutting head while the mill is running.
