Safe Work Procedure
1. Check MSDS sheet for chemical to be decanted and check for manufacturer’s recommendations on
handling. Wear any Personal Protective Equipment (PPE) which is necessary. Ensure that all materials for
the task are assembled prior to removing chemical from storage.
2. Remove the chemical bottle to be decanted from storage. Use an appropriate caddy, tote, or cradle to
assist in transporting from one location to another if necessary.
3. Place smaller container to be filled on a firm, level surface at about waist level. If the MSDS indicates
the decanting may produce harmful vapors, decanting must then take place in a working fume hood.
4. Select an appropriate sized funnel for the task.
5. Support the funnel in an appropriate holder, such as a ring stand with clamp or similar device and
ensure that the container to be filled is located directly beneath the spout of the funnel.
6. Carefully support the original larger container with both hands and controlled so the mouth of the
container is near the mouth of the funnel.
7. Slowly pour the chemical into the funnel, ensuring the amount of product does not rise to closer than
one inch (2.5cm) from the top of the funnel.
8. Stop to allow the product to flow through the funnel and fill the second container without overflowing
the second container. Cap the second container when filled.
9. Repeat steps 3-8 as necessary until the necessary number of containers is achieved.
10. Place Workplace Label on second container as per WHMIS guidelines for the product.
11. Return original and secondary containers to storage, and secure the cabinet or storage area.
Note: If the purpose of the transfer is to create diluted stock solution of corrosive chemical, always start
the transfer after having placed about one half of the required water into the receiving container. Top up
the remaining water after decanting the chemical.
