Risk Assessment title: Handling and injecting colchicine into rodents
Step 1: Identify the activity
IMPORTANT: colchicine is used therapeutically to treat gout at 0.5 to 1 mg per dose. Rats will receive up to ~ 5 mg in total. The
concentrated substance is toxic to blood, kidneys, lungs, the nervous system, the reproductive system, liver, and mucous
membranes. Repeated or prolonged exposure to the substance can produce target organs damage. Repeated exposure of the eyes
to a low level of dust can produce eye irritation. Repeated skin exposure can produce local skin destruction, or dermatitis. Wastes
including faeces and urine from exposed animals must be handled with caution. The experimental operator must wear personal
protective equipment (impermeable disposable lab gown or laboratory gowns with disposable sleeves, gloves (nitrile or double latex
gloving), masks when handling these compounds, injecting animals and handling wastes from animals exposed to this substance.
It is rapidly metabolized and sequestered in tissues, so that concentrations in urine and faeces in exposed animals are likely to be
small.
i) Transport of compounds between departments (pharmacy, laboratory, animal handling facility)
ii) Preparing compounds.
iii) Injection/gavage into animals.
iv) Handling of animal waste from exposed animals.
v) Processing diagnostic urine samples and blood samples from exposed animals.
v) Spill management

Describe the location: Wallace Wurth Building, Level 6
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.
Experimental operator: Staff member, student
Other laboratory staff/students
Animal handling facility members
Visitor/contractor
Bystanders to spills
Steps 3 to 7: Identify the hazards, risks, and rate the risks
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. Re-rate the risk if additional risk controls used.

It is important to monitor risk controls and review risk assessments regularly. Review is required when there is a change in the process, relevant legal changes, and where a cause for concern has

What you need to do
1. Consider what can go wrong that can hurt someone
2. Determine what the most likely outcome would be - Consequences
3. Determine how likely those consequences are - Likelihood
4. Calculate the risk rating
