Is mouth pipetting acceptable?

Mouth pipetting is considered unacceptable in any laboratory setting due to the significant health risks associated with the practice. The primary concern is the potential for ingesting hazardous substances, including chemicals or biological materials that could pose serious health threats. Laboratory safety protocols emphasize the use of appropriate pipetting tools, such as mechanical pipettors or safety pipettes, which provide a safer and more effective means of transferring liquids without the risk of exposure.

The focus on safety in laboratory environments aligns with best practices in handling potentially toxic, infectious, or volatile substances. Training and safety manuals, such as the CSMLS Safety Manual, reinforce these standards to protect laboratory personnel from potential harm and to promote hygienic methods for liquid transfer. Adhering to these guidelines is critical for maintaining a safe and healthy work environment in any laboratory setting.
