STEP 3 – REVIEW CHEMICAL PROCESS
For each stage of the chemical risk assessment:
Hierarchy of Control (Control Type)

Review the prompts/examples for each route of exposure for each category;
El – Elimination

Determine and record a raw risk score by referencing the two variable risk matrix or the three variable risk calculator;
S – Substitution

In the comments box, describe the route of exposure and any other information (if applicable);
En – Engineering

Specify the risk control type for each current or proposed risk control;
Sh – Shielding

Provide a control description for each current or proposed risk control;
A – Administrative T – Training

Where proposed risk control(s) have been identified complete a Health & Safety Action Plan;
M – Monitoring

Determine the residual risk score referencing the same two variable risk matrix or three variable risk calculator used to determine the raw
risk score.
