On October 22, 1980, a compliance officer of the Occupational Safety and Health Administration (OSHA) of the Department of Labor applied for a warrant to inspect portions of the premises of Rockford Drop Forge Company (Rockford) in Rockford, II *628 linois. Magistrate Mahoney issued an ex parte inspection warrant on the same day. Five days thereafter Rockford filed a complaint for declaratory and injunctive relief in the district court. The complaint contended that the warrant violated Rockford’s rights under the Fourth Amendment, was issued without sufficient probable cause, and was issued ex parte even though Rockford had asked defendant Secretary of Labor and various OSHA officials and employees, also defendants, to give Rockford advance notice of an application for an inspection warrant.
Rockford’s complaint before the district court alleged two causes of action. The first stated that OSHA has no power to obtain ex parte warrants under the following circumstances: Defendant Ronald Stephens, an OSHA compliance officer, appeared at Rockford’s premises on September 9,1980, pursuant to an August 29,1980, complaint filed with OSHA by Marvin O. Thompson for the Blacksmiths and Boilermakers Local Lodge No. 1614 (Union). Stephens was refused admission to Rockford’s premises because he had no search warrant to conduct a safety and health investigation of Rockford. On the same day and again two days thereafter, Rockford requested Harold Gier, an OSHA safety supervisor, to give Rockford notice should it apply for an inspection warrant.
The complaint then alleged that on October 22, 1980 — without notice to Rockford— Stephens applied to the magistrate for an inspection warrant based upon the August 29 complaint, another Union complaint dated September 11, 1980, -nd a summary of visual observations made by Union members on October 7, 1980. Magistrate Mahoney issued the ex
parte
inspection warrant on the same day. On the following day, Stephens and defendant Gregory Mitchell, OSHA Area Director, presented Rockford with the inspection warrant and a copy of the September 11 complaint. Rockford objected to the warrant and search for the following reasons: “invalidity of the warrant, ex
parte
issuance, failure to comply with the standards established by
Barlow [Marshall v. Barlow’s, Inc.,
In the second cause of action Rockford claimed that the inspection warrant was “not supported by a written complaint from an employee” because the Union allegedly did not represent Rockford employees. The Union had been on strike since July 23, 1979. Rockford also alleged that the Union’s complaint referred to “item # 15 which is not contained in the complaint.” 1 Therefore, the inspection warrant assertedly was “improper, unlawful, and violate[d] the Fourth Amendment of the United States Constitution as it was issued without sufficient probable cause, as required by Marshall v. Barlow[’]s, Inc.” (App.A.36).
Rockford requested a declaratory judgment that the application for the warrant and the inspection warrant were unconstitutional under the Fourth Amendment and that the inspection itself also violated Rockford’s Fourth Amendment rights. In addition to asking the district court to quash the search warrant, Rockford requested suppression of any evidence obtained from the partial inspection and an injunction against further action by OSHA.
In March 1981, Judge Roszkowski granted Rockford’s motion to quash the inspection warrant and to suppress the evidence obtained thereunder. In his accompanying opinion, the district judge invalidated the warrant because it was issued ex
parte
notwithstanding Rockford’s request to be present at the hearing on the application for the warrant. The court rejected Rockford’s position that the Union was an improper complainant because it did not represent any employee currently working for Rockford. Following our decision in
Burkart Randall Division of Textron, Inc. v.

Marshall,
We hold that the ex parte OSHA inspection warrant was valid and therefore reverse.
OSHA Was Empowered to Obtain This Inspection Warrant Ex Parte.
Although an OSHA inspection was permitted to take place over Rockford’s objection on October 23, 1980, this case is not moot because on the following day plaintiff terminated any further attempts to inspect its facilities. The case is also not moot because the district court granted Rockford’s motion to suppress evidence obtained under the inspection warrant. Therefore we must decide the merits of plaintiff’s principal argument that the inspection warrant was properly quashed on the ground that it issued ex parte. The question of OSHA power in this case should not recur regarding ex parte warrants obtained after November 3, 1980, in light of subsequent amendments to OSHA regulations. See 45 Fed.Reg. 65916 (Oct. 3, 1980).
First of all, we note that the purpose of the Occupational Safety and Health Act is “to assure so far as possible every working man and woman in the Nation safe and healthful working conditions.” Section 2(b), 29 U.S.C. § 651(b). Consequently the defendant Secretary was authorized by Congress “to enter without delay and at reasonable times” any place of employment and “to inspect and investigate during working hours and at other reasonable times * * *.” Section 8(a) of the Act, 29 U.S.C. § 657(a). In addition, Section 8(g)(2) of the Act directs the Secretary to prescribe “rules and regulations dealing with the inspection of an employer’s establishment.” 29 U.S.C. § 657(g)(2). In 1971, the Secretary promulgated 29 C.F.R. § 1903.4 which permits appropriate officials to “promptly take appropriate action, including compulsory process, if necessary,” upon an employer’s refusal to permit entry by OSHA.

Warrantless inspections conducted under these provisions were invalidated by the Supreme Court in
Marshall v. Barlow’s, Inc.,
Barlow’s was decided in May 1978 and in December of that year the Secretary took advantage of the Supreme Court’s suggestion and amended 29 C.F.R. § 1903.4 by defining “compulsory process” to mean “the institution of any appropriate action, including ex parte application for an inspection warrant or its equivalent.” 29 C.F.R. § 1903.4(d). As the Secretary explained, the agency considered it already had power to obtain ex parte warrants under the prior unamended regulation because it allowed use of “compulsory process.” The amendment was made only “to make explicit that the Secretary is authorized to obtain ex parte warrants or their equivalent.” 43 Fed.Reg. 59839.
The foregoing history shows that the statute and regulations permitted the Secretary to seek inspection warrants ex parte and that the procedure employed here was approved in advance by the Supreme Court’s opinion in Barlow’s. Since the present warrant was issued on October 22, 1980, the 1978 version of Section 1903.4 applies.
Rockford, however, asserts that the 1978 amendment to the regulation was invalid because the Secretary did not follow the rule-making procedures required by Section 4(b) of the Administrative Procedure Act (5 U.S.C. § 553(b)). While there is some authority for this position,
Donovan v. Huffhines Steel Co.,
Rockford also contends that the warrant is invalid because it had requested OSHA to give advance notice of an application for an inspection warrant. This contention is without merit because the Supreme Court had stated in
Marshall v. Barlow’s, Inc., supra,
Obviously, to permit an employer [through the giving of notice] to appear before the magistrate and contest the issuance of an inspection warrant would conflict with the explicit congressional policy that OSHA inspections be undelayed and without notice. In addition, the Court agrees with the Secretary that an adversary proceeding, such as is sought by Warren in this case, could only result in an unreasonable and unnecessary burden on the Secretary. The inevitable effect would be to “undermine the efficient and speedy implementation of the Act” contemplated by Congress * * * and to require an unwarranted “consumption of enforcement energies” that would “exceed manageable proportions.” (Citations omitted.)
This Warrant Did Not Lack Probable Cause.
Plaintiff also argues that there was no probable cause for the issuance of this warrant. This argument was rejected out of hand by the district judge. His decision was clearly correct in view of the allegations of the complaints to the Secretary by the Union’s representative attached as exhibits to the sworn warrant application. The September 11, 1980, complaint alleged 14 unsafe conditions in violation of OSHA regulations (App.A.17-A.19). On October 8, 1980, this was modified to 8 dangerous conditions (App.A.20-A.24). These allegations were set forth carefully in the application and plainly furnished “sufficient detail to evaluate OSHA’s decision to conduct an inspection based on these complaints.”
Burkart Randall Division of Textron, Inc. v. Marshall, supra,
The Warrant Was Not Overbroad in Scope.
Judge Roszkowski also rejected Rockford’s assertion that this warrant was overbroad in scope because the Secretary “indicated that he interprets the warrant to authorize only an inspection of the complaint areas” (App.A.50). See note 3 supra. The warrant itself is limited to the forge building, the forge shop, the trim room, “and those areas in plain view in which the compliance officer observes hazardous conditions * * * and all other things relating to these [hazardous] conditions and [aforesaid] areas * * * bearing on whether this * * * place of employment [is] free from recognized hazards that are causing or likely to cause death or serious physical injuries to its employees * * *.” Because of these limitations, we may accept without question OSHA’s statement that the “Secretary does not intend to execute the warrant except as to the complaint and plain view areas” (Reply Brief 16), but to avoid further disputes we will limit the warrant’s scope to those areas.
It Is Immaterial That the Complaints to OSHA Came From Striking Employees.
Rockford’s final argument is that because the Union was on strike, the three employee members mentioned in the warrant application were not employees or representatives of Rockford’s current employees and therefore not proper complainants under Section 8(f)(1) of the Act, 29 U.S.C. § 657(f)(1)
(supra
n.2). We rejected a similar argument in
Burkart Randall Division of Textron, Inc. v. Marshall, supra,
For the foregoing reasons the judgment of the district court is reversed, but the geographic scope of the warrant is limited “to the complaint and plain view areas,” and the phrase “which may be done by attaching personal monitoring devices to employees” is stricken from lines 5 and 6 on page 2 of the warrant. We do not decide whether OSHA may attach personal monitoring devices to employees under its new regulations.
Notes
. A perusal of the Union’s complaint (App.A. 17-A.20) shows that due to a typographical error, # 15 should have been # 13. The latter alleges employee exposure to electrical shock from damaged electrical cords to a fan in the forge shop (App.A.18-A.19).
. Section 8(f)(1) provides:
Any employees or representative of employees who believe that a violation of a safety or health standard exists that threatens physical harm, or that an imminent danger exists, may request an inspection by giving notice to the Secretary or his authorized representative of such violation or danger. Any such notice shall be reduced to writing, shall set forth with reasonable particularity the grounds for the notice, and shall be signed by the employees or representative of employees, and a copy shall be provided the employer or his agent no later than at the time of inspection, except that, upon the request of the person giving such notice, his name and the names of individual employees referred to therein shall not appear in such copy or on any record published, released, or made available pursuant to subsection (g) of this section. If upon receipt of such notification the Secretary determines there are reasonable grounds to believe that such violation or danger exists, he shall make a special inspection in accordance with the provisions of this section as soon as practicable, to determine if such violation or danger exists. If the Secretary determines there are no reasonable grounds to believe that a violation or danger exists he shall notify the employees or representative of the employees in writing of such determination.
. In response to Rockford’s argument that the warrant was overbroad, the Secretary advised the district court that he interpreted the warrant to authorize only an inspection of the complaint areas, but the court suggested without deciding that any future warrant application should identify the areas and documents to be inspected. The court also refused to decide whether OSHA is authorized to take samples by attaching personal monitoring devices to employees. We invalidated such sampling in
