Some workers at the Merlus Fishing factory in Walvis Bay are still apprehensive about returning to work following an ammonia leak that they were exposed to on Wednesday.

The ammonia leak occurred at a fishing vessel that was being repaired near the factory.

The incident, which affected 25 people with seven requiring medical attention, has left workers feeling unsafe or apprehensive about returning to the site without further clarification on the situation or improved safety measures. 

The workers say it is important for the company or responsible parties to address the workers' concerns, be transparent about the cause of the leak, and assure them that appropriate steps are being taken to prevent a repeat of such incidents.

They further say that communication is key in such situations to maintain trust and ensure the safety of all employees.

This comes after an investigation conducted by the Ministry of Labour has established that Wednesday's ammonia leak that affected workers at the Merlus Factory in Walvis Bay originated from a nearby vessel that was undergoing maintenance.

Ammonia gas is commonly used on shipping vessels for several important purposes, primarily related to refrigeration and air conditioning systems.

Exposure to ammonia gas can have a range of harmful effects on the human body, depending on the concentration and duration of the exposure. 

Ammonia is a highly irritating and toxic substance, and its effects can vary from mild irritation to severe health issues. 

The Namibia Food and Allied Workers Union branch coordinator, Johny Shiyuka, urged both employers and employees to create a suitable working environment.
