SST Safe work method statements (SWMS) - Describes how work is to be carried out. (Order of work) - It identifies the work activities which may have risks. - Describes control measures that can be used to nullify risks, and how they should be implemented. - Description of the equipment that will be used. - Standards of work, and the qualifications of the personnel undertaking the work. Safety Data Sheet (SDS) also can be known as the MSDS - Outlines the high risk activities, hazards that may arise, and measures to control the risk. - Document prepared by the supplier of a chemical product. The document states the hazardous nature. - Document shows precautions that must be followed to ensure that the material doesn’t impact anyone. - Includes ways to respond in emergency situations. Person Conducting Business Undertaking (PCBU) - A PCBU conducts business alone or with others. Safe operating procedure (SOP) - Description of how to use machines, and tools Job Safety Analysis - A procedure which describes the steps required to complete a certain task. - JSA should be completed before the SWMS - Analysis of the Job, identifying potential hazards, assessing associated risks and outlining control measures - Comparing to SWMS, JSA just lists the control measures, whereas SWMS describes them. Duty of care - Ensuring Safety for others, and yourself.

Identifying, assessing and controlling risks and hazards Hazard- Anything in the workplace that has the potential to harm, injure, damage, kill

or impact people or equipment. - Acute Hazard- Short term exposure to the hazard will cause an injury. (E.g Being burnt in an explosive fire) - Chronic Hazards- Long Term exposure to the hazard will cause injury, and sickness. (E.g SKin Cancer occurring from extended exposure to the sun.) Hierarchy of Hazard Controls 1st priority- Elimination 2nd Priority- Substitution 3rd priority- Engineering Controls (Isolation and guarding) 4th Priority- Administrative controls (Training and work scheduling) 5th Priority- PPE Measurements

Work Health and Safety - Work Health and Safety Act 2011 ❏ Provides a framework to protect the health, safety and welfare of all workers at work. It also protects the health and safety of all other

people who might be affected by the work. All workers are protected by this WHS act ❏ Regulating Authority is Safework NSW -

PPE -

Reasons for development of WHS Laws ❏ Self regulation not working ● Organisations regulating their own WHS programs wasn’t working. Evidence of this is 500 people were dying nationally due to work related accidents. ❏ National and overseas legal developments ● National, and international efforts to update WHS legislation. Made it modernised to the twentieth century. ❏ Many Workers not covered ● When WHS began approximately 1/3 of the workforce was covered. Today all workers are covered. ❏ Too much legislations ● There were 26 different acts, which over complicated the legislations. WHS brought upon stability. ❏ Cost of Compensation ● WHS legislation was introduced in conjunction with workers' compensation to provide for injured workers.

Formal meetings will have an agenda, which all workers have been made aware of. It will consist of minutes, and notes from the meeting to be recorded. Formal meetings are run by a chairperson who is usually people involved in the work site. Informal meetings can occur on short notice, and information about the work will be exchanged A toolbox meeting is an example of both a formal, and informal meeting. Purpose of meetings is to pass on information, resolve disputes, make workers aware of any amendments, and planning for future work.

Methods of ensuring a safe work environment - Barricades: Prevents entry, and signifies that a danger exists. - Signage: Informs others of hazards, dangers and required ppe. - Housekeeping: Ensuring work area is clean, and clear of any hazards. AN example could be sweeping any dust, or rubbish away from work areas. Plan Interpretations and specifications - Site or Block Plan ❏ Essential for determining the location of the building block. ❏ Information on a site plan: ❖ Distance from street to boundary ❖ Distance from side boundary to building ❖ Contour lines, and their heights. ❖ Trees ❖ Direction of North ❖ Lot number

-

Floor Plan ❏ Horizontal cut through section of the building as viewed from above. It is the most important of all the related views as it contains most of the information for construction. ❏ Items shown are: ❖ Dimensions of walls ❖ Door and Window positions ❖ Position of cupboards, stoves, laundry tubs, etc

-

Elevations ❏ Provide information relating to vertical measurements, and external finishes. ❏ They show: ❖ Height of finished floor level (FFL) ❖ Design of the building

-

Sections ❏ Elevations that cut through the building. ❏ The section is a cross section from the bottom of the footing, through the walls, ceiling, and roof structures. ❏ The information provided on sections are: ❖ Footing sizes ❖ Floor Construction ❖ Roof Pitch ❖ Section Sizes

-

Construction Details ❏ Sectional views drawn to a larger scale. ❏ Information it includes are ❖ Scale used for drawings ❖ Dimensions ❖ Title Block

Tools and

Equipment - Hammer ❏ Deliver an impact. E.g Driving nails into wood ❏ Types of Hammers: ➔ Claw Hammer ➔ Ball Pein Hammer - Chisel ❏ Used for carving, and cutting. ❏ Types of chisels: ➔ Mortise Chisel ➔ Bevel Edge Chisel Jobs in Construction - Carpenter ❖ Installation of timber wall frames. ❖ Installation of doors, and windows.
