What precaution should be taken when working in septic environments?

Using protective gear when working in septic environments is essential due to the hazardous nature of the tasks involved. Septic systems can contain harmful pathogens, toxic gases, and other contaminants that pose health risks to workers. Protective gear typically includes gloves, eye protection, masks, and coveralls, which serve to minimize exposure to harmful substances and prevent infection.

The other options, while they may have their benefits in different contexts, do not adequately address the primary concern of worker safety in septic environments. For instance, while using biodegradable products can be environmentally friendly, it does not necessarily protect a worker from exposure to harmful substances. Working only during daylight may enhance visibility but does not mitigate any hazards present. Similarly, using manual tools might reduce certain risks associated with powered equipment, but it does not provide the necessary protection from the exposures inherent in septic environments.
