(b) Air.

1. (1) The air filtration system for the procedure room and for the embryology laboratory must provide twenty (20) air changes per hour.
2. (2) If the rooms are adjacent, there must be positive pressure from the embryology laboratory room to the procedure room.

(e) Walls and floors.

1. (1) Walls and floors must be composed of materials that are:

   1. (A) Easily washed and disinfected; and
   2. (B) Not physically affected by germicidal and cleaning solutions.

2. (2) Wall bases must be:

   1. (A) Made integral and covered with the floor;
   2. (B) Tightly sealed within the wall; and
   3. (C) Constructed without voids that can harbor insects.

(g) Adequate space and mutual accessibility.

1. (1) The laboratory must be constructed and arranged to ensure adequate space for the performance and reporting of tests and for equipment.

2. (2)

   1. (A) The embryology laboratory must be located within one hundred feet (100 ft.) of the oocyte collection/procedure room.
   2. (B) The presence of a general access hallway between the embryology laboratory and the procedure room is not recommended.

3. (4)

   1. (A) As an alternative, oocyte identification and isolation can be performed in the procedure room, using a self-contained, temperature- and environmental-controlled, microscope/incubator unit.
   2. (B) Oocytes can then be transported within this unit (or in a portable incubator) to the embryology laboratory.

(h) Safety.

1. (1) Aerosols and toxic pest control substances must not be used.
2. (2) Non-toxic (non-powdered) gloves must be worn while handling gametes and embryos.
3. (3) Toxic fumes that could be harmful to gametes and embryos must be eliminated.
4. (4) All compressed gas cylinders must be secured to prevent falling.
