4.1 Introduction
4.1.1 Part II contains requirements for the users of powered industrial trucks. Included are requirements for operator qualifications and training, operating safety rules, and maintenance practices.
4.1.2 Unusual operating conditions may require additional safety precautions and special operating instructions.
4.1.3 Supervision is an essential element in the safe operation of powered industrial trucks.
4.2 Modifications, Nameplates, Markings, and Capacity
4.2.1 Except as provided in para. 4.2.2, no modificatioris or alterations to a powered industrial truck that may affect the capacity, stability, or safe operation of the truck shall be made without the prior written approval of the original truck manufacturer or its successor thereof. When the truck manufacturer or its successor approves a modification or alteration, appropriate changes shall be made to capacity plates, decals, tags, and operation and maintenance manuals.
4.2.2 If the truck manufacturer is no longer in business and there is no successor to the business, the user may arrange for a modification or alteration to a powered industrial truck, provided however, the user
(a) arranges for modification or alteration to be designed, tested, and implemented by an engineer(s) expert in industrial trucks and their safety
(b) maintains a permanent record of the design, test(s), and implementation of the modification or alteration
(c) makes appropriate changes to the capacity plate(s), decals, tags, and operation and maintenance manuals
(d) affixes a permanent and readily visible label on the truck stating the manner in which the truck has been modified or altered together with the date of the modification or alteration, and the name of the organization that accomplished the tasks
4.2.3 If the truck is equipped with a front-end attachment(s), including fork extensions, the user shall see that the truck is marked to identify the attachment(s),
– Properly running internal combustion engines will still produce carbon monoxide emissions and deplete the oxygen supply sufficiently, affecting the ambient air of the work environment if the ambient air exchange is not adequate. Always use ventilation as the primary means of control by providing necessary air exchange capabilityc
4.11.2 Ventilation shall be provided in enclosed areas where internal combustion-powered equipment is used to maintain an atmosphere that shall not exceed the contamination levels specified by the American Conference of Governmental Industrial Hygienists, “Threshold limit Values of Airborne Contaminants.” (See 29 CFR 1910.1000 Table Z-l.) This includes the atmosphere within the truck cab when a cab is provided.
4.11.3 Common symptoms of carbon monoxide exposure may include headaches, diziiness, and nausea. If employees exhibit these symptoms, move them into fresh air, seek medical attention as required, and determine the source of carbon monoxide by monitoring “threshold limit values” in areas of exposure.
4.11.4 Questions concerning degree of concentration and methods of sampling to ascertain the conditions present should be referred to a qualified professional. Users must follow applicable local, state, and federal regulations that apply to their workplace.
4.12 Sound
Powered industrial trucks can contribute to the ambient sound in the work area. Consideration should be given to the sound exposure of personnel in the work area.
4.13 Dockboards (Bridge Plates)2
4.13.1 Portable and powered dockboards shall be marked conspicuously with their carrying capacity. The carrying capacity indicated shall not be exceeded.
4.13.2 Portable dockboards shall be secured in position, either by being anchored or by being equipped with devIces that will prevent their slipping.
4.13.3 Handholds or other effective means shall be provided on portable dockboards to permit safe handling. Where possible, fork loops or lugs shall be provided for handling by fork trucks.
4.13.4 All types of dockboards shall have a high friction surface designed to reduce the possibility of employees or trucks slipping.
