OPINION
OGG, Chief Judge,Division 1.
The two issues raised in this appeal are:
1. Was the respondent employee, Charles R. Mugg, entitled to benefits under the Workmen’s Compensation Act as a covered employee of the Department of Economic Security under the provisions of A.R.S. § 23-901.-4(f)?
2. Was this a valid industrial injury where the activity engaged in at the time of the injury was common to the public in general and was not peculiar to the employment activities?
We affirm the award.
The facts are undisputed. Respondent sustained an industrial injury to his back while working in Oklahoma. He underwent surgery for ruptured discs. Permanent disability resulted, for which he received compensation.
After relocating in Arizona, he consulted a vocational rehabilitation counselor of the Department of Economic Security’s Division of Vocational Rehabilitation (hereinafter DES and DVR, respectively). This counseling led him to select welding as his vocational goal. Training options included on-the-job training with a private employer, vocational training at a local community college, or vocational training at a private technical school. Because on-the-job opportunities were unavailable and the private school offered the best training, respondent chose to attend a private school and enrolled at the ABC School of Welding.
Respondent was unable to obtain private disability insurance because of his injury. Prior to undertaking training, he questioned the counselor about the consequences of re-injury during training. He testified that the counselor assured him that he was protected by workmen’s compensation coverage. The counselor testified that he could not recall making any specific representation, but that under the administrative guidelines applicable then, he thought respondent was eligible for coverage and sought to qualify him.
The Department paid respondent’s relocation, subsistence and tuition expenses. The training consisted of approximately two hours of classroom instruction and six hours of shop work per day. Upon successful completion, the trainee received a school diploma and/or a Certificate of Completion. This technical instruction was considered the equivalent of two years of on-the-job training.
While at work on an assigned project in the school shop, respondent bent from the waist to pick up a scrap of metal from the floor. Although the motion required only ordinary bending and the weight of the metal was negligible, he severely strained his back. The injury compelled him to leave school and obtain medical treatment.
THE COVERAGE UNDER A.R.S. § 23-901.4(f) ISSUE
This issue, whether a vocational trainee attending a private technical school under the DVR’s rehabilitation program is a DES employee, is one of first impression. Its resolution turns on the meaning of A.R.S. § 23-901.4(f), which provides as follows:
Any person placed in on-the-job evaluation or on-the-job training under the department of economic security’s vocational rehabilitation program shall be deemed to be an employee of such department for the purpose of coverage under the state workmen’s compensation laws only. .
Any person receiving vocational rehabilitation services under the department of economic security’s vocational rehabilitation program whose major evaluation or training activity is academic, whether as an enrolled attending student or by correspondence, or who is confined to a hospital or penal institution, shall not be deemed to be an employee of the department for any purpose, (emphasis added)
*587The first class that the statute designates includes persons placed in on-the-job evaluation or training. Members of this class are explicitly deemed DES employees. Membership in this class requires placement in on-the-job evaluation or training.
We disagree with petitioners’ contention that failure to qualify for membership in this class necessarily determines that a trainee is not a DES employee. Statutes must be interpreted as a whole. See Long v. Dick, 87 Ariz. 25, 347 P.2d 581 (1959). A.R.S. § 23-901.4(f) designates a second class. The two classes, therefore, must be interpreted together.
The second class includes, inter alia, persons receiving vocational rehabilitation services whose major evaluation or training activity is academic. Members of this class are explicitly not deemed DES employees.
If petitioners were correct that only members of the first class were DES employees, the second class would be either unnecessary or limited to on-the-job placements whose major training activity is academic. Both alternatives are absurd; the first renders the second class redundant, the second restricts its membership to an inconsequential group.
The statutory language does not compel this interpretation. The class of persons receiving vocational rehabilitation services whose major training activity is academic presupposes a more inclusive category of all persons receiving vocational rehabilitation services, both academic and non-academic. By explicitly excluding as DES employees only academic trainees, the statute implicitly includes as DES employees non-academic trainees.
The statutory history supports this interpretation. Two versions of A.R.S. § 23-901.4(f) preceded the present one. The first provided as follows:
Any person who performs service for an employer as a trainee for the purpose of vocational rehabilitation under the terms of any recognized public or private program is deemed to be an employee.
Laws 1970, Ch. 187, § 1. The second provided as follows:
Any person being evaluated or trained in vocational activities or who performs service for an employer as a trainee under the auspices of vocational rehabilitation division is deemed to be an employee of the vocational rehabilitation division.
Laws 1971, Ch. 173, § 6.
The evolution from the first to the second version indicates a legislative intent to shift the burden of providing workmen’s compensation coverage for on-the-job trainees from the private employer to the DES and to expand the class of covered trainees from those performing service for employers to all vocational trainees. The evolution from the second to the present version indicates a legislative intent to keep the coverage burden for on-the-job trainees on the DES (the first class), and to exclude academic trainees from the class of covered trainees (the second class). If the legislature had intended to limit DES employees to on-the-job trainees, it would have simply eliminated the language of the second version that expanded coverage to all trainees, rather than merely excluding the limited class of academic trainees.
Sound policy underlies these distinctions. Unless DES assumes the coverage burden, private employers are unlikely to provide on-the-job training for disabled persons. Similarly, because the trainee probably cannot obtain private disability insurance when training involves hazards similar to industrial employment, i. e., when training is non-academic, the disabled person is unlikely to assume the risk of reinjury unless he is protected. The first classification solves the employer’s problem; the second solves the trainee’s.
We conclude that under A.R.S. § 23-901.4(f), any person receiving vocational rehabilitation services whose major evaluation or training activity is not academic in nature shall be deemed a DES employee.
The statute defines neither the term “on-the-job” nor the term “academic.” “On-the-job”, as commonly used, denotes a training position with a private employer. *588It is conceded that respondent’s placement at a private technical school did not constitute on-the-job training. He, therefore, was not a member of the first class of DES employees.
There are two possible interpretations for the term “academic”. Under the broad interpretation, the term means training occurring at a school. The more narrow interpretation of “academic” means instruction occurring in a classroom, as opposed to technical training occurring in a workshop or in the field.
The same arguments applicable to interpretation of the statute as a whole are applicable to the interpretation of the term “academic”. To interpret it broadly would, in effect, limit DES employee status to on-the-job trainees.
There is sufficient evidence in the record to support the hearing officer’s determination that the major training activity at the ABC School of Welding was not academic in nature. As of the date of the accident, the training had consisted of two hours of classroom instruction offered each week with six hours each day devoted to practical welding experience in the workshop. Given the statutory language, its history, and its underlying policy, it is our opinion that the respondent was a DES employee under the terms of A.R.S. § 23-901.4(f).
THE COMPENSABILITY OF THE ACCIDENT ISSUE
The petitioners contend that because an ordinary bending motion caused the injury, no compensable accident occurred. Two distinct problems are involved. We must determine whether the injurious incident constituted an industrial accident and second, if it did, whether such accident arose out of the employment.
The hearing officer correctly decided that the incident was an accident. It is unnecessary for the incident (bending action) to be unexpected or extraordinary. It is sufficient that the consequences of the incident (the acute lumbar strain) are unforeseen or uncommon. An injury is caused by an accident within the Workmen’s Compensation Act when either the external cause or the resulting injury itself is unexpected or accidental. See Paulley v. Industrial Commission, 91 Ariz. 266, 371 P.2d 888 (1962).
The second problem, which the hearing officer did not specifically address, focuses on the required relationship between the risk giving rise to the injury and the employment. It is unnecessary for the employment to create a special risk of injury. See Pauley v. Industrial Commission, 109 Ariz. 298, 508 P.2d 1160 (1973). The employer takes the employee as he finds him. See Employers Mutual Liability Insurance Company of Wisconsin v. Industrial Commission, 17 Ariz.App. 516, 498 P.2d 590 (1972). It is sufficient that this bending action while engaged in welding activity increased the risk of injury to respondent. The accident, therefore, arose out of the employment.
In summary, because respondent was a DES employee and a compensable accident occurred, the hearing officer properly awarded benefits under the Arizona Workmen’s Compensation Act.
Award affirmed.
