Workers were currently treating about 12 tonnes of 36 tonnes of affected products. Neutralising mercaptan smell was a slow process and would take a certain time, the officials added.
Samples taken at the site showed the concentration of mercaptan had gone down to 20 parts per million (ppm), from 80 ppm on Monday, they said.
Meanwhile, authorities on Wednesday morning lifted bans on vehicle and pedestrian traffic near the plant, and some 270 workers at five nearby plants resumed work.
Batho said the incident was not posing health risks, given the low concentrations of mercaptan in the release. However, at high concentrations mercaptan could pose health risks, she said.
The cause of the incident was “without doubt” due to negligence, Batho said, but she added it would be up to an official investigation to establish the exact cause.
US-based Lubrizol said on Tuesday that following the incident it temporarily suspended operations at the lubricants additives plant. The company was investigating the incident to determine an exact cause and identify any needed corrective actions, it said.
