According to OSHA, what must portable containers used for drinking water be?

Portable containers used for drinking water must be tightly sealed and equipped to ensure the safety and integrity of the water being provided. This requirement helps prevent contamination from external sources, such as dirt, insects, and other potential pollutants that could compromise the quality of the drinking water. Additionally, proper sealing of these containers supports hygienic conditions essential in workplaces, particularly in construction sites where exposure to various contaminants is typical.

Ensuring that these containers are equipped may also refer to features like a dedicated spout or tap, which allows for easy and sanitary access to the water without needing to open the container frequently, thus maintaining its cleanliness. Proper handling and maintenance of these portable drinking water sources are essential under OSHA standards to promote worker health and safety on construction sites.
