Pension and Other Postretirement Benefits Disclosure [Text Block] | Note 9 - Retirement plans Pension plan The defined benefit plan that covered Winchester filtration hourly rated employees was frozen on June 30, 2013 per the third Amendment to the Plan dated May 15, 2013. Per the third amendment, the accrued benefit of each participant was frozen as of the freeze date and no further benefits shall accrue with respect to any service or hours of service after the freeze date. The benefits are based on fixed amounts multiplied by years of service of participants. The Company engages outside actuaries to calculate its obligations and costs. The funding policy is to contribute such amounts as are necessary to provide for benefits attributed to service to date. The amounts contributed to the plan are sufficient to meet the minimum funding requirements set forth in the Employee Retirement Income Security Act of 1974. Asset allocation The plans hold no securities of MFRI, Inc. 100% of the assets are held for benefits under the plan. The fair value of the major categories of the pension plans' investments are presented below. The FASB has established a fair value hierarchy that distinguishes between (1) market participant assumptions developed based on market data obtained from independent sources (observable inputs) and (2) an entity's own assumptions about market participant assumptions developed based on the best information available in the circumstances (unobservable inputs). The fair value hierarchy consists of three broad levels, which gives the highest priority to unadjusted quoted prices in active markets for identical assets and liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value hierarchy are described below: Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Level 2 - Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates); and inputs that are derived principally from or corroborated by observable market data by correlation or other means. Level 3 - Inputs that are both significant to the fair value measurement and unobservable.

At January 31, 2014, plan assets were held 50% in equity, 37% in debt, 2% in real estate securities and 11% in other. The investment policy is to invest all funds not needed to pay benefits and investment expenses for the year, with target asset allocations of 55% equities (with a range of 40% - 65%), 25% fixed income (with a range of 20% - 35%) and 20% Alternative Investments (with a range of 15% - 25%), diversified across a variety of sub-asset classes and investment styles, following a flexible asset allocation approach that will allow the plan to participate in market opportunities as they become available. The expected long-term rate of return on assets is based on historical long-term rates of equity and fixed income investments and the asset mix objective of the funds. Investment market conditions in 2013 resulted in $531 thousand actual return on plan assets as presented below, which increased the fair value of plan assets at year end. The Company did not change its 8% expected return on plan assets used in determining cost and benefit obligations, the return that the Company has assumed during every profitable and unprofitable investment year since 1991. The plan's investments are intended to earn long-term returns to fund long-term obligations, and investment portfolios with asset allocations similar to those of the plan's investment policy have attained such returns over several decades. Future contributions that may be necessary to maintain funding requirements are not expected to materially affect the Company's liquidity.

The discount rate was based on a Citigroup pension discount curve of high quality fixed income investments with cash flows matching the plans' expected benefit payments. The Company determines the expected long-term rate of return on plan assets by performing a detailed analysis of historical and expected returns based on the strategic asset allocation approved by the Board of Directors and the underlying return fundamentals of each asset class. The Company's historical experience with the pension fund asset performance is also considered.

401(k) plan The domestic employees of the Company participate in the MFRI, Inc. Employee Savings and Protection Plan, which is applicable to all employees except employees covered by collective bargaining agreement benefits. The plan allows employee pretax payroll contributions of up to 16% of total compensation. The Company matches 50% of each participant's contribution, up to a maximum of 3% of each participant's salary. For employees covered by the Winchester Bargaining Unit Savings Plan, the Company matches 15% of each participant's contribution, up to a maximum of 6% of each participant's salary. Contributions to the 401(k) plan were $430 thousand and $560 thousand for the years ended January 31, 2014 and 2013, respectively. Deferred compensation plan The Company has a Supplemental Retirement and Deferred Compensation Plan ("Supplemental Plan"), pursuant to which key employees deferred compensation. Life insurance contracts have been purchased which may be used to fund the Company's obligation under these agreements. Participants receive distributions from the plan at the later of age 65 or six months after separation from service. Distributions can be lump sum or annual payments over a specified number of years based on elections made when the participant enters the plan.

On April 10, 2014, the Company's Boar d of Directors terminated the Supplemental Plan and its Deferred Stock Purchase Plan, adopted on December 5, 2012 (collectively, the "Plans"), effective April 10, 2014 ("Termination Date"). No additional contributions will be made by the Company or participants under the Plans after the Termination Date. All funds and Company stock remaining in participant accounts will be distributed not later than 24 months after the Termination Date. As of the Termination Date, the Company was obligated to deliver 28,891 shares of Company common stock under the Deferred Stock Purchase Plan. Multi-employer plans The Company contributes to a multi-employer plan for certain collective bargaining U.S. employees and for foreign employees according to their countries requirements. The risks of participating in this multi-employer plan are different from a single employer plan in the following aspects:
• | Assets contributed to the multi-employer plans by one employer may be used to provide benefits to employees of other participating employers.
• | If a participating employer ceases contributing to the plan, the unfunded obligations of the plan may be inherited by the remaining participating employers.
• | If the Company chooses to stop participating in the multi-employer plan, the Company may be required to pay those plans an amount based on the underfunded status of the plan, referred to as a withdrawal liability.
The Company has assessed and determined that the multi-employer plans to which it contributes are not significant to the Company's consolidated financial statements. The Company does not expect to incur a withdrawal liability or expect to significantly increase its contribution over the remainder of the contract period. The Company made contributions to the bargaining unit supported multi-employer pension plans.
