Install computer wiring and other cables appropriately to prevent such hazards. Avoid all use of electrical extension cords. Two major factors in determining an appropriate class size are the number of special needs students and the extent of their needs. NFPA Occupancy Load standards require a minimum of 50 net square feet per occupant in science laboratories. For safety as well as pedagogical purposes, the NFPA square footage per occupant should be increased and the NSTA maximum number of students in a laboratory should be reduced in a class accommodating students with special needs.
Thoughtful scheduling is another way administrators can make a difference.
Lab periods can be scheduled in tandem with special education resource periods, if appropriate. This helps facilitate special PPT requirements, for example, extended test time, special assistance, and other accommodations. Common planning periods for special education and science teachers are essential for co-teaching team members. During these planning periods, the special education teacher can focus on modifications of the lesson plan and the science teacher on modifications for laboratory safety. Finally, school districts have a responsibility to provide professional development on an ongoing basis.
