The Americans with Disabilities Act of 1990. The ADA is a wide-ranging civil rights law that prohibits, under certain circumstances, discrimination based on disability. It affords similar protections against discrimination to Americans with disabilities as the Civil Rights Act of 1964, which made discrimination based on race, religion, sex, national origin, and other characteristics illegal. Disability is defined as a physical or mental impairment that substantially limits a major life activity. The determination of whether any particular condition is considered a disability is made on a case by case basis. Section II and III deal with the accessibility aspects that concern the automatic door industry.
