Procedures for Safe Working With Micro-organisms

Step 1: Carry out a risk assessment in order to determine the Containment Level that must be applied in order to carry out the work safely.

Step 2: Adhere to the relevant Containment Level Procedures.

Important Definitions

Containment Level: the combination of physical and operational requirements necessary to work with a particular micro-organism or to perform a particular procedure or manipulation safely. The ACDP and SACGM define four Containment Levels (1 to 4) in their published guidance. The ACDP guidance is solely concerned with the hazards to human health. The SACGM system builds upon the ACDP system with the addition of measures specifically intended to protect the external environment.

General Laboratory: Any laboratory area out with the TC suites.

Genetic Modification: The alteration of the genetic material of an organism in a way that does not occur naturally by mating and/or natural recombination.

Micro-organism: A microbiological entity, cellular or non-cellular, capable of replication or of transferring genetic material. This includes bacteria, fungi, protozoa, viruses and viroids, prions, cell and tissue cultures from humans, animals and plants, and full-length copies of viral genomes that are known to be infectious even when they are not encapsulated or enveloped.
