OSHA GENERAL SAFTY AND HEATH PRACTICE

BLUE PRINT READING � � A blueprint is a reproduction of a technical drawing, documenting an architecture or an engineering design, using acontact print process on light-sensitive sheets. Invented in the 19 th century, the process allowed rapid and accurate reproduction of documents used in construction and industry. The blue-print process was characterized by light colored lines on a blue background, a negative of the original. The process was unable to reproduce color or shades of grey. Various base materials have been used for blueprints. Paper was a common choice; for more durable prints linen was sometimes used, but with time, the linen prints would shrink slightly. To combat this problem, printing on imitation vellumand, later, polyester film (Mylar) was implemented.

MASONRY

CARPENTERY � Carpentry is a skilled trade in which the primary work performed is the use of wood to construct items as large as buildings and as small as desk drawers. [Note: in the UK, strictly speaking, the term is more correctly used to describe the skill involved only in 'First Fixing' of timber items and mainly covers areas such as constructing roofs, floors and timber framed buildings - i. e. those areas of construction that are normally unseen in the finished building. 'Second Fix' work - i. e. skirting boards, architraves, doors etc. , is more correctly referred to as 'Joinery'. ] Carpentry is also used to construct the formwork into which concrete is poured during the building of structures such as roads and highway overpasses. [Note: in the UK, the skill of making timber formwork for poured (in situ) concrete, is referred to as 'shuttering'. ] While the primary material used is wood, the construction of walls with metal studs, and concrete formwork with reusable metal forms is a carpentry skill.

WELDING AND FARICATION

ELICTRICAL � Electrical wiring in general refers to insulated conductors used to carry electricity, and associated devices. This article describes general aspects of electrical wiring as used to provide power in buildings and structures, commonly referred to as building wiring. This article is intended to describe common features of electrical wiring that may apply worldwide. For information regarding specific nationalelectrical codes, refer to the articles mentioned in the next section. Separate articles cover long-distance electric power transmission andelectric power distribution.

AIR-CONDITION AND REFRIGERANT

RIGGING � � � The system of ropes, cables, or chains employed to support a ship's masts (standing rigging) and to control or set the yards and sails. . . The action of providing a sailing ship with sails, stays, and braces.

HAND POWER TOOLS � Hand power tools are a common part of our everyday lives and are present in nearly every industry. These tools help us to easily perform tasks that otherwise would be difficult or impossible. However, these simple tools can be hazardous and have the potential for causing severe injuries when used or maintained improperly. Special attention toward hand power tool safety is necessary in order to reduce or eliminate these hazards.

OXY-FUEL WELDING � In oxy-fuel welding, a welding torch is used to weld metals. Welding metal results when two pieces are heated to a temperature that produces a shared pool of molten metal. The molten pool is generally supplied with additional metal called filler. Filler material depends upon the metals to be welded.

HOUSE KEEPING � � Housekeeping refers to the management of duties and chores involved in the running of a household. It is also used to refer to the money allocated for such use. [1] By extension, an office or organization, as well as the maintenance of computer storage systems. [2] A housekeeper is a person employed to manage a household, [3] and the domestic staff. According to, the housekeeper is second in command in the house and "except in large establishments, where there is a house steward, the housekeeper must consider herself as the immediate representative of her mistress".
