Fix

Work through the following list to control risks from hazardous substances. In many instances, a combination of approaches will result in the best solution.

1. Eliminate the hazardous substance

The best option is to remove the substance completely, so you should always try to do this first.

Example: Use a physical process rather than a chemical process to clean an object.

2. Use a safer substance, isolate the substance from people or use engineering controls

If you can’t remove the substance altogether, think about changing the form of the substance or the way that it is used.

Example: Use a detergent instead of a chlorinated solvent for cleaning, or install exhaust extraction to remove contaminants.

3. Use administrative controls

If you can’t change the substance or processes, try to change the way the work is done.

Example: Reduce the number of employees exposed to the substance by performing the task out of normal working hours.

4. Provide personal protective equipment

If no other measures will totally solve the problem, use personal protective equipment to reduce the risk.

Example: Provide employees with respirators.
