On October 6, 1977, plaintiff, the union representative of correctional officers employed at the Detroit House of Correction (hereinafter, DeHoCo), petitioned the Michigan Employment Relations Commission (hereinafter, the Commission) for a formal determination as to whether the officers were eligible for arbitration under the compulsory arbitration statute, MCL 423.231 et seq.; MSA 17.455(31) et seq.
In an order dated May 17, 1978, the Commission held that it possessed the requisite jurisdiction necessary to effect a settlement of the controversy, and in addition ruled that the prison guards were within the act’s coverage and therefore entitled to mandatory arbitration. The City of Detroit and DeHoCo appeal that determination by leave, raising three issues, only one of which merits distended consideration.
Defendants’ initial argument, that the Commission lacks the jurisdiction and authority to hear and decide the question of plaintiff’s eligibility for compulsory arbitration, has been recently rebuffed by this Court in In The Matter of Metropolitan Council 23, AFSCME, AFL-CIO, 89 Mich App 564; 280 NW2d 600 (1979), wherein it was held that the legislative intent to afford public employees within the scope of the act an expeditious and effective procedure for the resolution of disputes1 would be ill-served by imposing the protracted delays ger*277mane to initial court review and resolution of the act’s comprehensiveness. Defendants’ claim, therefore, is without merit.
Defendants also maintain that the Commission erred in determining that DeHoCo is a state rather than a city facility.
MCL 423.232; MSA 17.455(32) defines "public police and fire department”, to which the compulsory arbitration act applies, as follows:
"any department of a city, county, village or township having employees engaged as policemen, or in fire fighting or subject to the hazards thereof.”
Assuming, arguendo, the validity of defendants’ contention, Green v Dep’t of Corrections, 30 Mich App 648, 652; 186 NW2d 792 (1971), aff'd 386 Mich 459; 192 NW2d 491 (1971), we are no closer to a resolution of the ultimate dispute on appeal, which is, whether the Commission erroneously ruled that the correctional officers were within the purview of the act. As is readily apparent from the provision above, the focal point of conflict is not whether DeHoCo is a city or state institution, but rather the identity of the prison guards’ employer. Since the guards are employed and paid by the City of Detroit, they clearly come, in this respect, within the ambit of the statute.
Hence, we turn to the dispositive issue, whether the Commission’s holding that the officers in question were subject to the same or similar hazards as faced by Detroit policemen was in accordance with the law and supported by competent, material and substantial evidence. Const 1963, art 6, § 28, MCL 423.23(e); MSA 17.454(25)(e), Michigan Employment Relations Commission v Detroit Symphony Orchestra, Inc, 393 Mich 116, 121-124; 223 NW2d 283 (1974).
*278Executive Deputy Chief James Bannon testified regarding the hazards generally encountered by Detroit police officers. They included walking beats, riding motorcycles, responding to radio reports of crimes, riding in patrol cars, and investigating narcotics cases, sex-related offenses, robberies and homicides. The police are charged with the general enforcement of all the criminal laws of the state, be they misdemeanor, felony, or motor vehicle connected. Police officers have an obligation to carry their identification cards, badges and guns even when off duty, and, accordingly, to respond to life threatening situations at any time. Police must assist firemen in their work. They also must respond to and intervene in family squabbles, which is one of the most dangerous of police activities since, on the national average, 50% of the police officers killed or injured are killed or injured in responding to domestic calls. Statistics were introduced evidencing the high rate of injur ries resulting throughout the entire spectrum of police activities. Bannon also indicated that, due to the stress of police work in urban communities, police officers have the highest occupational rates of suicide and divorce, and one of the highest rates of alcoholism in the country.
The functions of the correctional guards, and their attendant risks, were explained by various witnesses, including the director of DeHoCo. Their testimony may be summarized as follows: the officers are responsible for maintaining order throughout the detention facility, and also patrol its perimeters on foot and in vehicles. They are accountable for the custody of prisoners to and from police agencies, courts and hospitals. In the event of a prisoner escape, they pursue and initially attempt an apprehension, always with the *279aid of weapons. They search prisoners and visitors for contraband such as weapons or narcotics; however, their power extends only to detention of the wrongdoer—the local police are alerted to effectuate the arrest. Although the guards are on call 24 hours a day, they are not authorized to carry a weapon or make an off-duty arrest. Most do not carry guns as part of their daily routine, but a full range of weapons (including mace, teargas, and other riot equipment) are kept on the premises for issue when necessary. Officers have, on occasion, been assaulted through prisoner attack, though not anywhere nearly as frequently as Detroit policemen. However, the potential for these attacks coupled with instances of inter-inmate conflicts exposes them to risks from which they suffer physical injuries.
Upon a careful review of the evidence and testimony proffered, we are unable to reach the conclusion that the Commission’s finding was devoid of the necessary record support. We view the instant case as a decidedly close one, and accordingly afford due deference to administrative expertise and decline to "invade the province of exclusive administrative fact-finding by displacing an agency’s choice between two reasonably differing views”.
