Occupational Health & Safety ICAITU004B

The Occupational Health & Safety Act  Clearly spells out duties for all workplace parties  Must be followed by employers and employee

Regulation  Rules that deal with certain issues in greater detail than are contained in the act e.g. first aid

Codes of Practice  Standards set by the industry for the industry  Minimum standards for workplace practices of OH&S

What should a OH&S policy do?  Indicate a company’s health and safety policy objectives  Arrangements to achieve these objective Issues include o Senior management commitment o Commitment to set down functions and duties of all people in the organization for maintaining workplace heath and safety o Accountability of all levels of management o Training in communication in health and safety practices o Regular monitoring/review effectiveness

Implementation of policy  Involves consultation and cooperation between management and employees  Policy document should be displayed in prominent place for employee to view

Hazard Management Approach (HMA)  Leads to reduced costs, increased productivity, higher morale and better industrial relations Responsibility of Health & Safety Employers o Must take all reasonable practicable steps to protect the health & safety at work of employees o Managers/Supervisors-responsible/accountable o Ensures Manager/Supervisors aware of responsibility o Ensure employee knows responsibility Employee

Health & Safety Representatives  Representatives of employees to represent them on health & Safety issues  To promote/ensure H&S they may: FreeAsAir [email protected]

o inspect workplace o consult managers/supervisors o issue provisional notices

Aim HMA  eliminate/reduce risk of injuries and illnesses associated with work. Through 1) Hazard identification Identify all situations/events that could give rise to potential injury/illness 2) Risk assessment Determining whether there are any risks associated with the identification hazards 3) Risk control Determining & implementing appropriate measures to control risk. Practicable means: o Severity of hazard o State knowledge of ways of removing it o Cost of removing 4) Evaluation of control measures Checking to see whether the introduced changes reduce the risk previously assessed e.g. repeat step 1,2, 3

Hazard: Potential to cause injury/illness Risk: Likelihood of injury/illness arising from exposure to any hazards

Identify Hazards in the office  Mechanical o Tripping, hot components of photocopiers  Physical o Reflections from VDU, poorly designed chairs, prolonged work in fixed posture  Chemical o Vapours e.g. paint

What to consider when assessing risk  Likelihood of exposure leading to injury/disease  Frequency/duration of exposure  Who it may effect?

What to consider when controlling risks  Elimination (most effective)  Substitution  Engineering e.g. barriers  Administration e.g. est. policies  Personal protective equipment e.g. gloves Evaluation of control measures

OH&S Committees FreeAsAir [email protected]

 Forum where health and safety problems can be identified and resolved and where safety systems/procedures can be developed and monitored  Meet at least every 3 months  Minutes must be recorded and meetings displayed prominently  Number of employer must not exceed employee  NOT ‘responsible’ for workplace health and safety o Employer ensures health, safety, welfare of employees o Only document and inform employer Functions:  Review measures to make workplace healthy & safe  Help develop safe working environment and system of work  Help develop a system to record accidents & hazards

Ergonomics Study of the physical relationship between people and their working environment Results in:  Increased work efficiency  Errors due to fatigue decreased  Health & injury problems reduced  Work satisfaction increased Work related problems  Eyestrain  headache/bloodshot eyes  Rapid fatigue due to prolonged static body position  Backache  Shoulder/neck stiffness  Repetitive Strain Injury (RSI) – caused when using body in unnatural position/carry out repeated actions

Considerations:  Design of furniture  Placement of equipment  Work Routine  Work environment  Incorporations of exercise and breaks into routines

Signs:  Red circle with a line through it: Some thing must be done (urgent)  Green Triangle: Indicates where emergency equipment is kept  Yellow Triangle: Danger, warning  Blue Circle: Need for safety equipment

What is the Internet? FreeAsAir [email protected]

 Worldwide groups of connected networks that allows the public to access information, send messages, obtain products/services  Networks use the same ‘language’ o Use the same protocols (rules)  ‘plat form- independent’ o Protocols devised so that can be understood by all main computer platforms

Connecting to the Internet ISP  Has a server which is permanently online and has a permanent internet address  Server connected through high-speed telephone lines, fiber optic links or satellite o Providing high speed data transfer  Connected to bank of modems  User modem dials up ISP’s modem and make a connection DIAL UP CONNECTION

IDSN Lines  Permanent phone line connection to an ISP o Transfer data faster o Come in a variety of bandwidths (data carrying capacity)

Web Server??? Own ISP  Larger organizations  Large network of computers and require high internet access

Choosing an ISP  Cost: prepaid/rate/joining fee  Speed: speed of modem supports/support lines for IDSN/cable modems  Lines: Line per customer  Start up Help: software provided- min. email program/borwser  Ongoing support  Experience  Platform: IBM Vs Macintosh Vs Windows version  Accounts: cheque?  Newsgroups: Limit to number can join?  Additional Mail Boxes e.g. AOL  Web Page: Space on server? Size? What is WWW?  World Wide Web  Portion of internet containing websites o Information can be accessed electronically o Collection of hyperlinked documents accessible on the internet o Hyperlinks allow you to move quickly from one document to another

 Web contains millions of documents known as Web Pages FreeAsAir [email protected]

o Held on various computer networks around the world

How a modem works

Packets

Firewall  Both hardware and software used to restrict access to data on a network  Used to deny access to outsiders and restrict employee’s access to sensitive data

Implementation  Place a computer “proxy server” between two separate networks o Programmed to allow access to/from only specific network locations

File Compression  Reduce download time  Internet is used to transfer files o File Transfer Protocol (FTP) – standard “language” used by computers o Allowing one program to transfer data to another e.g. Archie, Fetch, Most Web Browsers  Decompression program needed for ‘expansion’

Search Engine (search tool)  Software program searches documents for specified keywords and returns a list of documents where the keywords o Matches 1+ keywords answered  Searches an index of Internet sites, which is always updated

Function  Send out automated ‘spiders’ ‘crawlers’ ‘robots’ to scour internet  Search engine sends out ‘spider’ to fetch as many documents as possible  Program: ‘indexer’ reads documents and creates an index based on words 1) User types in word/phrase 2) Matched against database 3) Search engine displays URL matching

Newsgroup  Collection of news and discussion groups accessed via the internet to a central location o Allows anyone to read/post messages on particular topic o Divided into groups and subgroups  Participation requires program called “newsreader”

Mailing List  List of email addresses identified by a single name FreeAsAir [email protected]

 Messages are distributed to a large number of people via email  Join = subscribe  Get off mailing List = unsubscribe  Lurking: on mailing list without posting messages  explore  Flaming: email of personal nature resulting in disagreements among members – don’t reply/inflame  Emotions

Search Engine Vs FTP Vs Archie Server  Search engine: Generally used to locate information  Archie: program that enables you to search for files anywhere on the internet by filename o FTP sites are searchable with Archie

Plug-in  Mini applications that add extra functions to web browsers o E.g. allows recognition/play audio/video files

Browser  Software file that allows you to view HTML files  Interprets and displays Web pages and enables you to link to other Web pages  Basic Function: interpret Hyper Text Markup Language  Modern browsers e.g. MS Windows Explorer/Netscape o Display/deal with Graphics o Play sounds & video o Transfer files

Creating a Web Page  Analyze o Purpose/Achieve/Audience o Important info legible? o Too many pictures/animations o Which web browsers does page support o Contacts/Feedback?  Design o Layout o Appropriate user interface with simple navigation tools o Home Page interesting to grab user’s attention  Implement Software o Web Editor/Web Authoring package: enables you to create Web Pages o Technically any software letting you save HTML format e.g. Word processing can be used – compatibility of MS Word Vs Macintosh upon upload Types 1)Text Based editors: help you create HTML files by inserting HTML codes that help you manage links o Requires some knowledge of HTML

2) WYSIWYG editors: work with visual representation of web page o Hides HTML code unless you want to see it o Import Clips like desktop publishing e.g. MS FrontPage

Text  Written in word processing package for proofread/spell-check  Fonts used will be stored on viewers computer  use common font

Graphics  KISS – slows time  Ensure people who choose to turn off “auto load” can still navigate  No discrimination for e.g. visually impaired

Icons/Symbols  Navigation aids

Sound/Video  Limits on modem i.e. bandwidths (data capacity)  Employ streaming : Delivered in small packets at regular intervals  sufficient  poor quality  Obtain permission FreeAsAir [email protected]

File Operations in Word  Manage files  Save document  Print  Open File  Send to..e.g. fax

Why a ‘bulleted’ paragraph called a hanging indent  Hanging indents paragraphs formatting in which the second and subsequent lines of a paragraph are indented more than the first line How do you select a particular type of ‘tab stop’ Tab Stop: a position you set for placing and aligning text on a page  Difference between soft/hard page breaks Soft: starts a new page (automatic) Hard: force page break at a specific location (manual)

Difference between ‘cut and paste’ ‘copy and paste’ Cut…: removes texts from the place and pastes it in another location Copy…: exact replica made and still can be pasted elsewhere

MS EXCEL FreeAsAir [email protected]

Difference between Workbook and Worksheet Workbook: file in which you work and store data, each workbook can contain many worksheets Worksheet: used to list and analyse data, primary document – also called ‘spreadsheet’, in columns, rows and always stored in workbook

Excel recognition of ‘formula’  “=”  or paste function “f(x)”

When should you use ‘absolute addressing’ Absolute References: cell reference that always refers to a cell in a specific location.  If “dollar” sign before letter/number e.g. $A$1 the column/row is absolute  Used when don’t want excel to adjust references when copying formula to different cell

Difference between ‘searching’ and ‘filtering’ Filtering:  Quick/easy way to find work with a subset of data in a list  Displays only the rows that meet criteria as specified Search:  Returns the number of the character at which a specific character/text setting is first found

The ‘IF’ Function  Enables decision making to be implemented in a worksheet  Three arguments: o A condition that is evaluated as either true or false o A true condition: value returned if condition true o False action: value returned if condition false  Must use relational operators to perform logical test  = < > <> <= >=

Lookup Functions  Used to ‘look up’ tables  In a lookup table, you use a formula to locate an item of data that is associated with another item of data in the same list  Data in table must be ‘sorted’ as: o Search starts from the left-most value in the table/list and o Works its way from lowest to highest value  2 commonly used functions o VLOOKUP(cell, Range i.e. table, value, column) o HLOOKUP()

DATABASES FreeAsAir [email protected]

Attribute: Field in relational database Field: Item of info in a record Record: Collection of related fields

Primary Key  Unique field  Identifies each record in a table  Must have a unique value, used to relate a table to foreign keys in other tables

Data ‘Form’  Clearer  Full field labels seen  Easily search/review data  Reduction in possibility of mistakes

Control  Graphic User Interface object e.g. text box  Allows user to control program/data choices

When would you use a query rather than find filter commands  Query can bring together data from multiple tables to serve as the source of data for a form, report or data access page 

What advantages do reports have over printed forms  You have control over the size and appearance of everything on a report  You can display the information the way you want to see it  Prints information and organized according to your specifications
