Cash and Cash Equivalents [Abstract]

Under the terms of the master netting arrangement, the financial institution has the right, ability and intent to offset a positive balance in one account against an overdrawn amount in another account. Amounts in each of the accounts are unencumbered and unrestricted with respect to use. As such, the net cash balance related to this pooling arrangement is included in Cash and cash equivalents in the unaudited Condensed Consolidated Balance Sheets.

Segment Information

Segment Reporting [Abstract]
Segment Information	Segment Information We are organized into four geographical operating segments that are based on management responsibilities: Northern North America, Latin America, Europe, Middle East & Africa, and Asia Pacific. The operating segments have been aggregated (based on economic similarities, the nature of their products, end-user markets and methods of distribution) into three reportable segments: Americas, International, and Corporate. The Americas segment is comprised of our operations in Northern North American and Latin American geographies. The International segment is comprised of our operations in all geographies outside of the Americas. Certain global expenses are allocated to each segment in a manner consistent with where the benefits from the expenses are derived. The Company's sales are allocated to each segment based primarily on the country destination of the end-customer. Adjusted operating income (loss), adjusted operating margin, adjusted earnings before interest, taxes, depreciation and amortization (EBITDA) and adjusted EBITDA margin are the measures used by the chief operating decision maker to evaluate segment performance and allocate resources. Adjusted operating income (loss) is defined as operating income (loss) excluding restructuring charges, currency exchange (gains) losses, product liability expense, loss on divestiture of MSA LLC, transaction costs and acquisition-related amortization. Adjusted operating margin is defined as adjusted operating income (loss) divided by segment net sales to external customers. Adjusted EBITDA is defined as adjusted operating income (loss) plus depreciation and amortization. Adjusted EBITDA margin is defined as adjusted EBITDA divided by segment net sales to external customers. The accounting principles applied at the operating segment level in determining operating income (loss) are generally the same as those applied at the unaudited condensed consolidated financial statement level. Sales and transfers between operating segments are accounted for at market-based transaction prices and are eliminated in consolidation. Reportable segment information is presented in the following table: (In thousands, except percentages) Americas International Corporate Consolidated Three Months Ended March 31, 2023 Net sales to external customers $ 280,267 $ 117,995 $ — $ 398,262 Operating loss (60,061) Restructuring charges (Note 3) 1,747 Currency exchange losses, net 4,175 Loss on divestiture of MSA LLC (Note 17) 129,211 Product liability expense (Note 17) 3 Amortization of acquisition-related intangible assets 2,305 Adjusted operating income (loss) 71,694 15,779 (10,093) 77,380 Adjusted operating margin % 25.6 % 13.4 % Depreciation and amortization 12,267 Adjusted EBITDA 80,494 19,058 (9,905) 89,647 Adjusted EBITDA margin % 28.7 % 16.2 % Three Months Ended March 31, 2022 Net sales to external customers $ 225,648 $ 105,044 $ — $ 330,692 Operating income 42,668 Restructuring charges (Note 3) 2,189 Currency exchange losses, net 3,271 Product liability expense (Note 17) 2,772 Amortization of acquisition-related intangible assets 2,336 Transaction costs (a) 607 Adjusted operating income (loss) 52,435 9,024 (7,616) 53,843 Adjusted operating margin % 23.2 % 8.6 % Depreciation and amortization 11,829 Adjusted EBITDA 60,796 12,362 (7,486) 65,672 Adjusted EBITDA margin % 26.9 % 11.8 % (a) Transaction costs include advisory, legal, accounting, valuation, and other professional or consulting fees incurred during acquisitions and divestitures.

Earnings Per Share [Abstract]
Earnings per Share	arnings per Share Basic (loss) earnings per share is computed by dividing net income, after the deduction of preferred stock dividends and undistributed earnings allocated to participating securities, by the weighted average number of common shares outstanding during the period. Diluted (loss) earnings per share assumes the issuance of common stock for all potentially dilutive share equivalents outstanding not classified as participating securities. Participating securities are defined as unvested stock-based compensation awards that contain nonforfeitable rights to dividends. Three Months Ended March 31, (In thousands, except per share values) 2023 2022 Net (loss) income $ (150,173) $ 35,542 Preferred stock dividends (10) (10) Net (loss) income available to common equity (150,183) 35,532 Dividends and undistributed earnings allocated to participating securities — (4) Net (loss) income available to common shareholders (150,183) 35,528 Basic weighted-average shares outstanding 39,224 39,291 Stock-based compensation awards (a) — 232 Diluted weighted-average shares outstanding 39,224 39,523 Antidilutive shares 180 — (Loss) earnings per share: Basic $ (3.83) $ 0.90 Diluted $ (3.83) $ 0.90 (a) During periods in which the Company incurs a net loss, stock-based compensation awards are excluded from the computation of diluted earnings per share because their effect would be anti-dilutive. As such, during periods in which the Company incurs a net loss, diluted weighted average shares outstanding are equivalent to basic weighted average shares outstanding.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company's effective tax rate for the three months ended March 31, 2023, was (121.7)%, which differs from the United States of America ("U.S.") federal statutory rate of 21% primarily due to the divestiture of MSA LLC and the non-deductible loss recorded on the derecognition of the product liability reserves and related assets. Refer to Note 17—Contingencies to the unaudited condensed consolidated financial statements in Part I Item 1 of this Form 10-Q for further information on this transaction. The Company's effective tax rate for the three months ended March 31, 2022, was 21.7%, which differs from the U.S. federal statutory rate of 21% primarily due to state income taxes partially offset by tax benefits on certain share-based payments. At March 31, 2023, the Company had a gross liability for unrecognized tax benefits of $3.4 million. The Company has recognized tax benefits associated with these liabilities of $1.8 million at March 31, 2023. The gross liability includes amounts associated with foreign tax exposure in prior periods. The Company recognizes interest and penalties related to unrecognized tax benefits in interest expense and operating expenses, respectively. The Company's liability for accrued interest related to uncertain tax positions was $0.3 million at March 31, 2023. We are subject to regular review and audit by both foreign and domestic tax authorities. While we believe our tax positions will be sustained, the final outcome of tax audits and related litigation may differ materially from the tax amounts recorded in our unaudited condensed consolidated financial statements.

Under the amended agreement, the Company may elect either a Base rate of interest (“BASE”) or an interest rate based on the London Interbank Offered Rate (“LIBOR”). The BASE is a daily fluctuating per annum rate equal to the highest of (i) 0.00%, (ii) the Prime Rate, (iii) the Federal Funds Open Rate plus one half of one percent (0.5%), (iv) the Overnight Bank Funding Rate, plus one half of one percent (0.5%), or (v) the Daily LIBOR Rate plus one percent (1.00%). The Company pays a credit spread of 0 to 175 basis points based on the Company’s net EBITDA leverage ratio and elected rate (BASE or LIBOR). The Company has a weighted average revolver interest rate of 5.74% as of March 31, 2023. At March 31, 2023, $536.1 million of the existing $900.0 million Revolving Credit Facility was unused, including letters of credit issued under the Facility. The Facility also provides an accordion feature that allows the Company to access an additional $400.0 million of capacity pending approval by MSA’s board of directors and from the bank group. On July 1, 2021, the Company entered into a Third Amended and Restated Multi-Currency Note Purchase and Private Shelf Agreement (the “Prudential Note Agreement”) with PGIM, Inc. (“Prudential”). The Prudential Note Agreement provided for (i) the issuance of $100.0 million of 2.69% Series C Senior Notes due July 1, 2036 and (ii) the establishment of an uncommitted note issuance facility whereby the Company may request, subject to Prudential’s acceptance in its sole discretion, the issuance of up to $335.0 million aggregate principal amount of senior unsecured notes. As of March 31, 2023, the Company has outstanding £48.8 million (approximately $60.3 million at March 31, 2023) of 3.4% Series B Senior Notes due January 22, 2031. Remaining maturities of this note are £6.1 million (approximately $7.5 million at March 31, 2023) due January 22, 2024, with annual maturities of £6.1 million through January 2031. On July 1, 2021, the Company entered into a Second Amended and Restated Master Note Facility (the “NYL Note Facility”) with NYL Investors. The NYL Note Facility provided for (i) the issuance of $100.0 million of 2.69% Series A Senior Notes due July 1, 2036, and (ii) the establishment of an uncommitted note issuance facility whereby the Company may request, subject to NYL Investors’ acceptance in its sole discretion, the issuance of up to $200.0 million aggregate principal amount of senior unsecured notes. The Revolving Credit Facility, Prudential Note Agreement and NYL Note Facility require the Company to comply with specified financial covenants, including a requirement to maintain a minimum fixed charges coverage ratio of not less than 1.50 to 1.00 and a consolidated leverage ratio not to exceed 3.50 to 1.00; except during an acquisition period, defined as four consecutive fiscal quarters beginning with the quarter of acquisition, in which case the consolidated net leverage ratio shall not exceed 4.00 to 1.00; in each case calculated on the basis of the trailing four fiscal quarters. In addition, the agreements contain negative covenants limiting the ability of the Company and its subsidiaries to incur additional indebtedness or issue guarantees, create or incur liens, make loans and investments, make acquisitions, transfer or sell assets, enter into transactions with affiliated parties, make changes in its organizational documents that are materially adverse to lenders or modify the nature of the Company's or its subsidiaries' business. All credit facilities exclude Mine Safety Appliances Company, LLC prior to the divestiture of this subsidiary on January 5, 2023, as discussed further in Note 17. During August 2021, the Company amended its Revolving Credit Facility to transition from Sterling LIBOR reference rates to Sterling Overnight Interbank Average Rate ("SONIA") reference rates. The Company will apply the optional expedients in ASC 848, Reference Rate Reform , to this modification and potential future modifications driven by reference rate reform, accounting for the modifications as a continuation of the existing contracts. Therefore, these modifications will not require remeasurement at the modification date or a reassessment of previous accounting determinations. As such, the Company does not anticipate the change in reference rates will have an impact on the Company’s unaudited condensed consolidated financial statements. Management continues to evaluate the Company’s other outstanding U.S. LIBOR based contracts to determine whether reference rate modifications are necessary. On January 5, 2023, the Company entered into a new $250 million term loan facility to fund the divestiture of MSA LLC, a wholly owned subsidiary. Under the agreement, the Company may elect either BASE or an interest rate based on the Secured Overnight Financing Rate. The Company pays a credit spread of 0 to 200 basis points based on the Company's net EBITDA leverage ratio and elected rate. The Company had a Term Loan interest rate of 6.22% as of March 31, 2023. As of March 31, 2023, the Company was in full compliance with the restrictive covenants under its various credit agreements.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy consists of three broad levels, which gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value hierarchy are: • Level 1—Observable inputs that reflect unadjusted quoted prices for identical assets or liabilities in active markets. • Level 2—Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. • Level 3—Unobservable inputs for the asset or liability. The valuation methodologies we used to measure financial assets and liabilities include the derivative financial instruments described in Note 15—Derivative Financial Instruments. We estimate the fair value of the derivative financial instruments, consisting of foreign currency forward contracts, based upon valuation models with inputs that generally can be verified by observable market conditions and do not involve significant management judgment. Accordingly, the fair values of the derivative financial instruments are classified within Level 2 of the fair value hierarchy. With the exception of our investments in marketable securities and fixed rate long-term debt, we believe that the reported carrying amounts of our financial assets and liabilities approximate their fair values. Our investments in available-for-sale marketable securities, primarily fixed income, were transferred to Sag Main Holdings, LLC, as part of our MSA LLC divestiture as described in Note 17—Contingencies. Prior to the divestiture, these investments were valued at fair value using quoted market prices for similar securities or pricing models. Accordingly, the fair values of the investments were classified within Level 2 of the fair value hierarchy. The amortized cost basis of our investments was $9.9 million as of December 31, 2022. The fair value was $9.9 million as of December 31, 2022, which was reported in Investments, short-term in the accompanying unaudited Condensed Consolidated Balance Sheets. Prior to the divestiture, changes in fair value were recorded in Other comprehensive (loss) income, net of tax. No impairment losses relating to these securities occurred during the three months ended March 31, 2023. All investments in marketable securities had maturities of one year or less and were in an unrealized loss position as of December 31, 2022. The reported carrying amount of our fixed rate long-term debt was $260.3 million and $266.5 million at March 31, 2023, and December 31, 2022, respectively. The fair value of this debt was $217.1 million and $218.3 million at March 31, 2023, and December 31, 2022, respectively. The fair value of this debt was determined using Level 2 inputs by evaluating similarly rated companies with publicly traded bonds where available or current borrowing rates available for financings with similar terms and maturities.

Contingencies

Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies Product liability The Company and its subsidiaries face an inherent business risk of exposure to legal claims arising from the alleged failure of our products to prevent the types of personal injury or death against which they are designed to protect. Product liability claims are categorized as either single incident or cumulative trauma. Single incident product liability claims. Single incident product liability claims involve incidents of short duration that are typically known when they occur and involve observable injuries, which provide an objective basis for quantifying damages. Management has established reserves for the single incident product liability claims of its various subsidiaries, including asserted single incident product liability claims and incurred but not reported ("IBNR") single incident claims. To determine the reserves, Management makes reasonable estimates of losses for single incident claims based on the number and characteristics of asserted claims, historical experience, sales volumes, expected settlement costs, and other relevant information. The reserve for single incident product liability claims was $1.5 million at March 31, 2023, and $1.4 million December 31, 2022. Single incident product liability expense was $0.1 million during both the three months ended March 31, 2023 and the three months ended March 31, 2022. Single incident product liability exposures are evaluated on an annual basis, or more frequently if changing circumstances warrant. Adjustments are made to the reserve as appropriate. The reserve has not been discounted to present value and does not include future amounts which will be spent to defend the claims. Cumulative trauma product liability claims. Cumulative trauma product liability claims involve alleged exposures to harmful substances (e.g., silica, asbestos and coal dust) that occurred years ago and may have developed over long periods of time into diseases such as silicosis, asbestosis, mesothelioma, or coal worker’s pneumoconiosis. Prior to the divestiture described below, one of the Company's former subsidiaries, Mine Safety Appliances Company, LLC ("MSA LLC"), was named as a defendant in various lawsuits related to such claims. These lawsuits mainly involve respiratory protection products allegedly manufactured and sold by MSA LLC or its predecessors. Management previously established a reserve for MSA LLC's potential exposure to cumulative trauma product liability claims. Prior to its divestiture, MSA LLC's total cumulative trauma product liability reserve was $395.1 million, including $13.4 million for claims settled but not yet paid and related defense costs, as of December 31, 2022. The reserve includes estimated amounts related to asserted and IBNR asbestos, silica, and coal dust claims expected to be resolved through the year 2075. The reserve was not discounted to present value and did not include future amounts which will be spent to defend the claims. Defense costs were recognized in the unaudited Condensed Consolidated Statements of Operations as incurred. At December 31, 2022, $65.1 million of the total reserve for cumulative trauma product liability claims was recorded in the Insurance and product liability line within other current liabilities in the Consolidated Balance Sheet and the remainder, $330.0 million, is recorded in the Product liability and other noncurrent liabilities line. Prior to the divestiture, MSA LLC's cumulative trauma product liability reserve was based upon an estimate of MSA LLC’s current and potential future liability for cumulative trauma product liability claims, in accordance with applicable accounting principles. See further discussion on the process and assumptions used to derive this estimate in Note 20—Contingencies of the consolidated financial statements in Part II Item 8 of MSA's Form 10-K for the year ended December 31, 2022. On January 5, 2023, the Company entered into a membership interest purchase agreement (the “Purchase Agreement”) with Sag Main Holdings, LLC (the “Buyer”). The Buyer is a joint venture between R&Q Insurance Holdings Ltd. (“R&Q”) and Obra Capital, Inc. (“Obra”). Under the Purchase Agreement, on January 5, 2023, the Company transferred to the Buyer all of the issued and outstanding limited liability company interests of MSAC LLC (the “Sale”). In connection with the closing, the Company contributed $341.2 million in cash and cash equivalents, while R&Q and Obra contributed an additional $35.0 million. As MSA LLC was the obligor for the Company's legacy cumulative trauma product liability reserves and policyholder of the related insurance assets, the rights and obligations related to these items transferred upon the sale to the Buyer. In addition, pursuant to the Purchase Agreement, the Buyer and MSA LLC have agreed to indemnify the Company and its affiliates for legacy cumulative trauma product liabilities and other product liabilities, and the Company has agreed to indemnify MSA LLC for all other historical liabilities of MSA LLC. This indemnification is not subject to any cap or time limitation. In connection with the sale, the Company and its Board of Directors received a solvency opinion from an independent advisory firm that MSA LLC was solvent and adequately capitalized after giving effect to the transaction. Following the completion of the sale and thus transfer, the Company no longer has any obligation with respect to pending and future cumulative trauma product liability claims relating to these matters. As such, all legacy cumulative trauma product liability reserves, related insurance assets, and associated deferred tax assets of the divested subsidiary were derecognized from our balance sheet and the Company incurred a tax-effected loss on the divestiture of MSA LLC of $199.6 million, including transaction related costs of $5.6 million. R&Q and Obra's joint venture has assumed management of the divested subsidiary, including the management of its claims and associated assets. Below is a summary of the impact of the divestiture of MSA LLC on our unaudited Condensed Consolidated Statements of Operations for the quarter ended March 31, 2023: (In millions) Three Months Ended March 31, 2023 Cash and cash equivalents $ (341.2) Current insurance receivables (17.3) Notes receivable, insurance companies (5.9) Noncurrent insurance receivables (110.3) Notes receivable, insurance companies, noncurrent (38.7) Current product liability 65.1 Noncurrent product liability 324.7 Loss on divestiture of MSA LLC before transaction costs (123.6) Transaction costs (5.6) Loss on divestiture of MSA LLC (129.2) Income tax expense (a) (70.4) Tax-effected loss on divestiture of MSA LLC $ (199.6) (a) Related to the write-off of deferred tax asset related to product liability reserve Insurance Receivable and Notes Receivable, Insurance Companies Many years ago, MSA LLC purchased insurance policies from various insurance carriers that, subject to common contract exclusions, provided coverage for cumulative trauma product liability losses (the "Occurrence-Based Policies"). Prior to the divestiture of MSA LLC, when adjustments were made to amounts recorded in the cumulative trauma product liability reserve, we calculated amounts due to be reimbursed pursuant to the terms of the negotiated Coverage-In-Place Agreements, including cumulative trauma product liability losses and related defense costs, and we recorded the amounts probable of reimbursement as insurance receivables. Insurance receivables at December 31, 2022 totaled $127.6 million, of which $17.3 million was reported in Prepaid expenses and other current assets in the unaudited Condensed Consolidated Balance Sheets and $110.3 million was reported in Insurance receivables and other noncurrent assets.

A summary of notes receivables from insurance companies balance is as follows: (In millions) Three Months Ended March 31, 2023 Year Ended Balance beginning of period $ 44.6 $ 48.5 Divestiture of MSA LLC (44.6) — Additions — 1.2 Collections — (5.1) Balance end of period $ — $ 44.6 Other Litigation Globe, a subsidiary of the Company, is defending claims in which plaintiffs assert that certain products allegedly containing per- and polyfluoroalkyl substances (“PFAS”) have caused harm, including injury or health issues. PFAS are a large class of substances that are widely used in everyday products. Specifically, Globe builds turnout gear from technical fabrics sourced from a small pool of specialty textile manufacturers. These protective fabrics have been tested and certified to meet industry standards, and some of them contain PFAS to achieve water, oil, or chemical resistance. At this time, no manufacturer of firefighter protective clothing is able to meet current National Fire Protection Association safety standards while offering coats or pants that are completely PFAS free. Globe believes it has valid defenses to these claims. These matters are at a very early stage with numerous factual and legal issues to be resolved. Defense costs relating to these lawsuits are recognized in the unaudited Condensed Consolidated Statements of Operations as incurred.

Product Warranty The Company provides warranties on certain product sales. Product warranty reserves are established in the same period that revenue from the sale of the related products is recognized, or in the period that a specific issue arises as to the functionality of the Company's product. The determination of such reserves requires the Company to make estimates of product return rates and expected costs to repair or to replace the products under warranty. The amounts of the reserves are based on established terms and the Company's best estimate of the amounts necessary to settle future and existing claims on products sold as of the balance sheet date. If actual return rates and/or repair and replacement costs differ significantly from estimates, adjustments to recognize additional cost of sales may be required in future periods. The following table reconciles changes in the Company's accrued warranty reserve: (In thousands) Three Months Ended March 31, 2023 Year Ended Beginning warranty reserve $ 15,230 $ 12,423 Warranty payments (2,479) (10,631) Warranty claims 2,554 14,544 Provision for product warranties and other adjustments (163) (1,106) Ending warranty reserve $ 15,142 $ 15,230
