General Guidelines for ADA Compatible Laboratories

Doors: Doors should have a minimum width of 32 inches to accommodate wheelchairs and should be easy to open (automatic or with lever handles).

Thresholds: No higher than 1/2 inch to prevent tripping hazards and make it easy for wheelchairs to pass over.

Accessible Pathways: Pathways to, from, and around the lab should be at least 36 inches wide to allow for easy movement.

Height Adjustability: Workbenches should be adjustable to accommodate seated and standing users. The recommended range is 28-34 inches high for wheelchair accessibility.

Clear Knee Space: A minimum of 27 inches of vertical clearance underneath workstations for wheelchair users.

Reachable Equipment: Ensure equipment and materials are within 15-48 inches of reach for seated and standing individuals.

Accessible Controls: Place controls for lab equipment (e.g., microscopes, centrifuges) within reach and make them operable with one hand without tight grasping or twisting.

Automatic Faucets: Use motion-sensor or easy-to-operate faucets, ideally with extended levers.

Accessible Shelving: Adjustable shelving that can be lowered or raised as needed; ideally, the top shelf should not be higher than 48 inches for those in wheelchairs.

Accessible Fume Hoods: Adjustable height hoods or a lower work area, with controls and viewing windows accessible from a seated position.

Safety Showers and Eyewash Stations: Ensure these are reachable for wheelchair users and easy to activate without great force. Floor markings and Braille signage can be helpful.

Braille and Raised Lettering: On doors, equipment, and exit signs to aid individuals with visual impairments.

Audible and Visual Alarms: Fire alarms, safety alerts, and emergency signals should have both sound and light cues.

Adequate Lighting: Bright, glare-free lighting, with adjustable task lighting at workstations.

Non-slip Flooring: For safety, especially around areas where chemicals or liquids may be used.

Accessible Software: Ensure lab software is compatible with screen readers and other assistive technologies.

Adjustable Monitor Arms and Keyboards: Flexible mounting for monitors and keyboards to accommodate seated and standing users.

Inclusive Training: All staff should be trained in inclusive practices and emergency procedures to assist those with disabilities.

Accessible Emergency Exits: Clearly marked exits with ramps or accessible pathways.

Modular Design: Use flexible, modular components that can be adjusted or reconfigured.

Input from Diverse Users: Involve people with disabilities in the design process to ensure all needs are met.
