Operation of laboratory waterbaths
Step 1: :- Identify the Activity and the location of the activity
Step 2: :- : Identify who may be at risk by the activity: A number of people
Description
of Activity
Waterbaths are used for warming tissue culture media and solutions to
37C. Other temperatures maybe used for other purposes such as heat
inactivating FBS.
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
Description
of Location
CSB, level 2, Wet Lab
Persons
at Risk
Staff /students using the equipment
Other laboratory staff/students and visitors/contractors working in
the immediate vicinity.
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.

Avoid using power boards and
NEVER use double adaptors

If smoke is detected coming from
a device or a cord feels warm,
switch off at the power and
contact the plant custodian. Put
an “out of order” sign on the
equipment.
Report all damaged power outlets
and plugs to Facilities (x55111)

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
In the case of a fire, if it is safe to do so, turn off the power to the waterbath at the power point. Alternatively, turn off the power at the laboratory emergency shutdown switch,
which is located on the LHS wall near the emergency shower when entering the lab. This is the switch for all power outlets in the laboratory. If safe to do so, use a fire blanket
or a fire extinguisher (CO2 or dry powder). Notify security (x777), the equipment custodian, laboratory manager and your supervisor.
For major emergencies dial x777. Inform all other laboratory members and evacuate the laboratory. Also notify the equipment custodian, laboratory manager and your
supervisor. There is an emergency exit from the main lab leading to fire stairs. Emergency Evacuation routes are displayed on noticeboards.

Step 12:- Acknowledgement of Understanding
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

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
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.
Medium
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.
Low
Act this month: Managed by local documented routine procedures which must include application of the hierarchy of controls.
