OPINION
In this special action the petitioner contends the Administrative Law Judge (AU) erred in concluding that her exposure tо pesticides while on the job resulted in an occupational disease which precluded recovery оf compensation. We agree and set aside the award.
Petitioner, a schoolteacher with expertise in the education of gifted students, came to Arizona from Illinois with a history of being especially allergic to рesticides. She accepted work with the respondent employer at its schools in Sells, Arizona, and began tеaching gifted students at the respondent employer’s high school, middle school and primary schools, somewherе between August 17 and August 22, 1987. During that week she suffered physical symptoms in her classroom at the middle school and was transferrеd to the basement of a 100-year-old mission building. She also suffered symptoms in a portable, modular classroom. She opined that the markers and carpets in this classroom irritated her pre-existing condition and requested transfer to another classroom. Between August 17 and October 30, 1987, she also noticed some occasional blurred vision аnd “drawing through the sinuses.”
On October 30, 1987, petitioner taught at the high school in. the morning and that night chaperoned a student danсe at the high school cafeteria. She became very flushed during the course of the evening and suffered diarrhеa, extreme fatigue, stomach cramping, a sore throat and had difficulty swallowing. She returned to work the following week and on November 3, 1987, she was advised by fellow employees that the entire high school, including the cafeteriа, as well as the exterior of her apartment, had been sprayed with a pesticide. She tried to continue tеaching at the high school, middle school and primary schools which by then had all been sprayed. She noticed рurple fingers, blurred vision and aching jaws. Her symptoms became progressively worse to the point where she cоuld not talk.
*69 Petitioner finally resigned at the suggestion of her immunologist in March 1988. Although she did not continue to suffer the same kinds of symрtoms after she resigned, she has been unable to enter any place where pesticides are used and hеr diet has been very limited. In July 1988 she attempted to present a puppet workshop at a senior citizens’ cеnter but almost immediately started losing her voice and was sick for four days thereafter. Upon investigation she ascertained that the senior citizens’ center had been sprayed with pesticides six months previous to her expоsure.
From the medical testimony presented to him the AU concluded that the petitioner had sustained some physiсal and/or psychological reaction to exposure to pesticide on the school grounds and рossibly at her employer-provided apartment on October 30, 1987. Relying on the decision in
Phoenix Pest Control v. Industrial Commission,
Petitioner contends that her pesticide exposure was not an occupational disease within the contemplation of A.R.S. §§ 23-901(12)(c) or 23-901.01, but was a compensable personal injury by accident arising out of аnd in the course of her employment within the meaning of A.R.S. §§ 23-901(12)(a) and 23-1021. We agree.
A worker is entitled to workers’ compensation under A.R.S. § 23-1021 if he or she is injured by an accident arising out of and in the course of his or her employment, unless the injury was purposely self-inflicted. Injury is caused by an “accident” within the Workers’ Compensation Act where either the externаl cause or resulting injury itself is unexpected.
Paulley v. Industrial Commission,
The AU’s reliance on
Phoenix Pest Control v. Industrial Commission, supra,
to characterize petitioner’s condition as an occupational disease was misplaced. An occupational disease is one that is due to causes and conditions characteristic of and peculiar to a particular employment, and not thе ordinary diseases to which the general public is exposed.
American Ins. Co. v. Industrial Commission of Arizona,
However, the elimination of her condition as an occupational disease does not mean that petitioner cannоt recover for an injury if she can show that there was an accident, in other words, that either the external cаuse or resulting injury was unexpected. Petitioner knew that she was allergic to pesticides and testified that she did not accept the position in the Indian Oasis School District until she was assured by the school district that she would not be re-exposed to the chemicals to which she reacted. Since the external cause and the resulting injury were, therefore, not ex *70 pected, she suffered an injury by “accident.”
The award is set aside.
