Good Laboratory Practices

Good laboratory practices help to maintain biosafety in TB lab settings. However, it is good to keep in mind that:

• NOTHING can totally eliminate the safety risk associated with the TB laboratory.
• Good laboratory practices with an emphasis on biosafety, significantly reduce the risk of laboratory-acquired infection.
• Specialized equipment aids good laboratory practice but does NOT replace it.

Good Laboratory Practices

• Biohazard signs (Figure 1) should be posted at the entrance to laboratories performing work on infectious agents and hazardous chemicals.

Figure 1: Biohazard Sign

• Laboratory access should be limited to essential staff.
• No eating, drinking, or smoking (Figure 2).
• No mouth pipetting (Figure 2).      

Figure 2: No eating or mouth pipetting in lab

• No placing pencils or pens in the mouth.
• Keep hands away from eyes and face.
• Always wash hands before leaving the lab.
• Remove gloves before handling phones, instruments or computers.
• Minimize the use of mobile phones.
• Lab coats must be decontaminated and laundered regularly (never take them home for laundering!)
