Original text. Later amendments are not shown.

  • Table I A presents minimum requirements for laboratory activities.

  • Table I B presents additions to and modifications of Table I A for glasshouse/growth-room activities involving GMMs.

  • Table I C presents additions to and modifications of Table I A for activities with animals involving GMMs.

  • Table II presents minimum requirements for activities other than laboratory activities.

In some particular cases, it might be necessary to apply a combination of measures, from Table I A and Table II, of the same level.

In some cases users may, with the agreement of the competent authority, not apply a specification under a particular containment level or combine specifications from two different levels.

In these tables ‘optional’ means that the user may apply these measures on a case-by-case basis, subject to the assessment referred to in Article 4(2).
