The other defendants are Travelers Insurance Company and the Second Injury and Compensation Assurance Fund.

General Statutes § 7-314a provides in relevant part: “death, disability and injury benefits, presumption, (a) Except as provided in subsection (e) of this section, active members of volunteer fire departments shall be construed to be employees of the municipality for the benefit of which volunteer fire services are rendered while in training or engaged in volunteer fire duty and shall be subject to the jurisdiction of the workers’ compensation commission and shall be compensated in accordance with the provisions of chapter 568 for death, disability or injury incurred while in training for or engaged in volunteer fire duty.

“(b) For the purpose of this section, the average weekly wage of a volunteer fireman shall be construed to be the average production wage in the state as determined by the labor commissioner under the provisions of section 31-309.”

General Statutes § 31-310 provides: “determination of average WEEKLY WAGE OF INJURED WORKER. CONCURRENT EMPLOYMENT. PAYMENTS from second injury fund. For the purposes of this chapter, the average weekly wage shall be ascertained by dividing the total wages received by the injured worker from the employer in whose service he is injured during the twenty-six calendar weeks immediately preceding that during which he was injured, by the number of calendar weeks during which, or any portion of which, such worker was actually employed by such employer, but, in making such computation, absence for seven consecutive calendar days, although not in the same calendar week, shall be considered as absence for a calendar week. When the employment commenced otherwise than at the beginning of a calendar week, such calendar week and wages earned during such week shall be excluded in making the above computation. When the employment previous to injury as provided above is computed to be less than a net period of two calendar weeks, his weekly wage shall be considered to be equivalent to the average weekly wage *481prevailing in the same or similar employment in the same locality at the time of injury except that, when an employer has agreed to pay a certain hourly wage to such worker, then the hourly wage so agreed upon shall he the hourly wage for such injured worker and his average weekly wage shall be computed by multiplying such hourly wage by the regular number of hours that is permitted each week in accordance with such agreement. For the purpose of determining the amount of compensation to be paid in the case of a minor under the age of eighteen years who has sustained an injury entitling him to compensation for total or partial incapacity for a period of fifty-two or more weeks, or to specific indemnity for any injury under the provisions of section 31-308, the commissioner may add fifty per cent to his average weekly wage, except in the case of a minor under sixteen years of age, in which case the commissioner may add one hundred per cent to his average weekly wage. When the injured employee is a trainee or apprentice receiving a subsistence allowance from the United States because of war service, such allowance shall be added to his actual earnings in determining the average weekly wage. Where the injured employee has worked for more than one employer at the time of injury and the average weekly wage received from the employer in whose employ he was injured, as determined under the provisions of this section, are insufficient for him to obtain the maximum weekly compensation rate from such employer under section 31-309 prevailing at the time of his injury, his average weekly wages shall be calculated upon the basis of wages earned from all such employers in the period of such concurrent employment not in excess of twenty-six weeks prior to the date of the injury, but the employer in whose employ the injury occurred shall be liable for all medical and hospital costs, a pro rata portion of the compensation rate based upon the ratio of the amount of wages paid by him to the total wages paid the employee in such average week but not less than an amount equal to the minimum compensation rate prevailing at the time of injury and, if he is totally incapacitated, the applicable dependency allowance, if any, due under section 31-308b. The remaining portion of the applicable compensation rate shall be paid from the second injury and assurance fund. In cases which involve concurrent employment and in which there is a claim against a third party, the injured employee or the employer in whose employ the injury was sustained or the employer’s insurer shall advise the custodian of the second injury fund if there is a third party claim, and such employee, employer or employer’s insurer shall pursue its subrogation rights as provided for in section 31-293 and shall include in its claim all benefits paid by the second injury fund and shall reimburse the second injury fund for all payments made for compensation in the event of a recovery against the third party.” This statute, in effect at the time this action was instituted, was amended by Nos. 91-32 and 91-339 of the 1991 Public Acts, effective July 1, 1991.

The certified question was: “Is a volunteer fire fighter eligible for benefits under General Statutes § 7-314a also eligible for concurrent employment benefits pursuant to General Statutes § 31-310?” Wislocki v. Prospect, 223 Conn. 911, 612 A.2d 58 (1992).

General Statutes (Cum. Sup. 1967) § 7-314a (a) (2) is the predecessor of the current § 7-314a (a). See Public Acts 1967, No. 892, § 2. Section 7-314a (a) (2) provided in pertinent part: “death, disability and injury benefits, (a) Active members of volunteer fire departments shall be compensated for death, disability or injury ... as follows ... (2) all other volunteer firemen who are not such public employees [for whom compensation is provided by general or special law] shall be construed to be employees of the municipality for the benefit of which volunteer fire services are rendered while in training or engaged in volunteer fire duty and shall be compensated in accordance with the provisions of chapter 568. . . .”

The amendment, Public Acts 1969, No. 464, § 1, which changed the statute in a number of respects, did not affect the proceedings in Going v. Cromwell Fire District, 159 Conn. 53, 267 A.2d 428 (1970), because in that case the volunteer firefighter had sustained his accidental injuries in 1968. Id., 55.

The 1969 amendment also added General Statutes § 7-314a (d), which provides: “For the purpose of adjudication of claims for the payment of benefits under the provisions of chapter 568, any condition of impairment of health occurring to an active member of a volunteer fire department while such member is in training for or engaged in volunteer fire duty, caused by hypertension or heart disease resulting in death or temporary or permanent total or partial disability, shall be presumed to have been suffered in the line of duty and within the scope of his employment, provided such member had previously successfully passed a physical examination by a licensed physician appointed by such department which examination failed to reveal any evidence of such condition.”

Section 7-314a was amended again in 1989, adding subsection (e), which provides: “Any member of a volunteer fire company or department performing fire duties pursuant to a mutual aid understanding between municipalities shall be entitled to all benefits pursuant to this section and shall be construed to be an employee of the municipality in which his fire company or department is located.” See Public Acts 1989, No. 89-22, § 2. Because the plaintiff sustained his injury in 1988, however, the 1989 amendment is not relevant in this case.
