This also involves the sacrifice of Cane Toads by Pithing and removing the skin off their legs. Students use the muscle in the practical. In Room E401 Anderson Stuart Building F13 Step 2: :- : Identify who may be at risk by the activity: A number of people may be at risk from any activity. This may affect the risk controls needed. These people may include fellow workers, visitors, contractors and the public. The location of the activity may affect the number of people at risk Persons at Risk Technical Staff, Academic Staff, demonstrators and students. Page 1 of 10
Step 3 to 7:- Identify Hazards, Risks and risk controls. 1. An activity may be divided into tasks. For each task identify the hazards and associated risks 2. List existing risk controls and determine a risk rating using the UNSW Risk Rating Procedure 3. Additional risk controls may be required to achieve an acceptable level of risk (Use hierarchy for risk controls).re- rate the risk if additional risk controls used.

Step 8: :- List Emergency procedures and controls.list Emergency controls for how to deal with fires, spills or exposure to hazardous substances and/or emergency shutdown procedures Emergency controls to deal with fire: 1. Contact Sydney University Security on Ext 13333 or (02) 9351 3333 2. Contain the fire and smoke only if safe to do so. That is close doors and windows, but ensure you have a safe exit path yourself. If safe to do so, extinguish the fire with fitted fire extinguishers or hose reels in the building 3. Evacuate yourself and others Emergency controls to deal with Spills: 1. Clear the area 2. Check for any persons involved 3. Contact Sydney University Security on Ext 13333 or (02) 9351 3333 4. Isolate the spill (if safe to do so) using suitable spill kits (Spill kit located N243 Anderson Stuart Building F13) Emergency controls to deal with Personal Injury: 1. For minor cuts inform first aid officer and use the nearest First Aid Kit. (First Aid kits Rm 329 Bio-Science and Rm N243 Anderson Stuart Building F13) ) 2. For minor burns place affected area under running tap water for at least 20 min 3. Call Sydney University Security on Ext 13333 or (02) 9351 3333 to seek medical help. Evacuation Procedure: 1. On hearing the alarm sounding as: beeep beeep.prepare to evacuate and follow instructions from any Public Announcements or Emergency Team members. Remove PPE wash hands, save files, turn off equipment, collect personal items and remain calm. 2. On hearing the alarm sounding as: whooop whooop.evacuate the building immediately. Leave the building via the nearest safe emergency exit. Do not use the lifts. Proceed as directed to the Evacuation Assembly Area, in front of the Anderson Stuart Building main entrance. 3.

All persons performing these tasks must sign that they have read and understood the risk assessment (as described in OHS329 Risk Assessment and Control Procedure). Note: for activities which are low risk or include a large group of people (e.g. open days, BBQ s, student classes etc), only the persons undertaking the key activities need to sign below. For all others involved in such activities, the information can be covered by other methods including for example a safety briefing, induction, and/or safety information sheet (ensure the method of communicating this information is specified in the risk assessment).

UNSW Concise OHS Risk Rating Table (OHS696) (Refer to OHS328 OHS risk rating procedure and/or OHS307 Hazard and Incident Reporting Procedure ) Step 1 Consider the Consequences What are the consequences of this event occurring? Consider what could reasonably happen with existing controls in place or if an incident has occurred consider what could have reasonably happened as well as what actually happened. Look at the descriptions and choose the most suitable Consequence. Step 2 Consider the Likelihood What is the likelihood of the consequence identified in step 1 happening? Look at the descriptions and choose the most suitable Likelihood Step 3 Calculate the Risk 1.Take the consequences rating (1-5) and select the correct column 2.Take the likelihood rating(a-e) and select the correct row 3. Select the risk rating where the two ratings cross on the matrix below. VH = Very high, H = High, M = Medium, L = Low CONSEQUENCES 5. Severe : death or permanent disability to one or more persons 4. Major : hospital admission required 3. Moderate :medical treatment required 2. Minor : first aid required 1. Insignificant: injuries not requiring first aid A. Almost certain: expected to occur in most circumstances B. Likely: will probably occur in most circumstances C. Possible: could occur at some time D. Unlikely: is not likely to occur in normal circumstances E. Rare: may occur only in exceptional circumstances LIKELIHOOD 1 2 3 4 5 A M H H VH VH B M M H H VH C L M H H VH D L L M M H E L L M M M Risk level Required action Very high Act immediately: The proposed task or process activity must not proceed. Steps must be taken to lower the risk level to as low as reasonably practicable using the hierarchy of risk controls. High Medium Low Act today: The proposed activity can only proceed, provided that: (i) the risk level has been reduced to as low as reasonably practicable using the hierarchy of risk controls; (ii) the risk controls must include those identified in legislation, Australian Standards, Codes of Practice etc. (iii) the risk assessment has been reviewed and approved by the Supervisor and (iv) a Safe Working Procedure or Safe Work Method has been prepared. (v) The supervisor must review and document the effectiveness of the implemented risk controls. Act this week: The proposed task or process can proceed, provided that: (i) the risk level has been reduced to as low as reasonably practicable using the hierarchy of risk controls; (ii) the risk assessment has been reviewed and approved by the Supervisor and (iii) a Safe Working Procedure or Safe Work Method has been prepared. Act this month: Managed by local documented routine procedures which must include application of the hierarchy of controls. Current Version: 3.3, 19/11/2010 Page 10 of 10
