Risk Assessment
Hazardous Substance
Risk Assessment Number: 2013:22
Only required for chemicals that are designated as Hazardous Substances
The chemical’s label and Material Safety Data Sheet (MSDS) will be needed to complete the risk
assessment.

1. How is the substance used? – i.e.
describe the process? (If the chemical is used
for a number of different processes a risk
assessment may be needed for each task. Also
consider decanting, storage and disposal)
2. How are people exposed to the
substance?
3. How much of the substance are the
workers exposed to during the task? (E.g. in
litres/millilitres)
4. How long are the workers exposed to
the substance? How often is the chemical used.
(E.g. I hours per day and days per week)
5. Briefly what are the health effects of
exposure to this substance? (Refer to MSDS)
AS SOLD
AT USE DILUTION
6. What engineering control measures (e.g.
extraction, ventilation; dilution) are
recommended by the MSDS and/or label?
7. Currently, what engineering controls are
used to control exposure to the substance?

delayed following exposure.
Exposure can cause nausea, headache
Ingestion:
and vomiting.
No known significant effects or critical
hazard
Dilution: Use 4 – 32mL/L in water.
Ventilation – AS SOLD & AT USE DILUTION: Good
general ventilation should be sufficient to
control worker exposure to airborne contaminants. If this
product contains ingredients with exposure limits, use
process enclosures, local exhaust ventilation or other
engineering controls to keep worker exposure below any
recommended or statutory limits.

Risk Score Calculator
Risk Assessment Method Using the Risk Assessment Calculator:
a. For each risk:
1. estimate the probability of a hazard resulting in an injury or disease;
2. estimate the duration of exposure a person has; and
3. the possible consequences that may result given (1) and (2) above;
4. use the Risk Assessment Calculator (below) to obtain a risk score.
b. Using the risk scores for each risk, develop a prioritised list of workplace risks
requiring action.

To use the Risk Assessment Calculator:





select the appropriate point on the probability scale;
draw a line, connecting the point on the probability scale with the appropriate
point on the exposure scale;
extend the line so that it intersects with the tie line;
from the point on the tie line, draw a line through the appropriate point on the
possible consequences scale; and
extend the line to the risk score scale.
