When should the sniff test for odorization be performed?

The sniff test for odorization should be performed when LP-gas is delivered to the bulk plant to ensure that the propane has the designated odorant mixed in at the correct level. This is an essential safety measure, as the odorization of propane is critical for detecting leaks; propane is naturally odorless. By conducting this test upon delivery, operators can confirm that the gas meets safety standards before it is distributed for use. Ensuring that the proper odorization is in place right at the point of delivery helps maintain safety through the entire distribution process.

Performing the sniff test at this stage assures that any issues related to odorization can be addressed immediately, minimizing the risk of undetectable leaks in the distribution system. This proactive step is crucial in upholding safety regulations and protecting both the facility's workers and the end customers.
