(xi) Owners and operators must ensure that respirators are used in compliance with the terms of the respirator's NIOSH certification.

(xii) Owners and operators must conduct regular evaluations of the workplace, including consultations with potentially exposed persons using respiratory protection, consistent with the requirements of 29 CFR 1910.134(l), to ensure that the provisions of the written respiratory protection program required under paragraph (f)(3) of this section are being effectively implemented.

(xiii) The respiratory protection requirements in this paragraph (f)(3) represent the minimum respiratory protection requirements, such that any respirator affording a higher degree of protection than the required respirator may be used.

(4) Dermal protection. (i) Owners or operators must require the donning of gloves that are chemically resistant to PIP (3:1) with activity-specific training where dermal contact with PIP (3:1) is reasonably expected. Owners or operators must minimize and protect potentially exposed persons from dermal exposure in accordance with 29 CFR 1910.132.

(ii) Owners or operators must supply and require the donning of dermal PPE that separates and provides a barrier to prevent direct dermal contact with PIP (3:1) in the specific work area where it is selected for use, selected in accordance with this paragraph (f)(4) and provided in accordance with 29 CFR 1910.132(h), to each person who is reasonably likely to be dermally exposed in the work area through direct dermal contact with PIP (3:1) For the purposes of this paragraph (f)(4), provisions in 29 CFR 1910.132(h) applying to an “employee” also apply equally to potentially exposed persons, and provisions applying to an “employer” also apply equally to owners or operators.

(iii) Dermal PPE that is of safe design and construction for the work to be performed must be provided, used, and maintained in a sanitary, reliable, and undamaged condition. Owners and operators must select PPE that properly fits each affected person and communicate PPE selections to each affected person.

(iv) Owners or operators must provide training in accordance with 29 CFR 1910.132(f) to all persons required to use dermal protection prior to or at the time of initial assignment to a job involving exposure to PIP (3:1). For the purposes of this paragraph (f)(4), provisions in 29 CFR 1910.132(f) applying to an “employee” also apply equally to potentially exposed persons, and provisions applying to an “employer” also apply equally to owners or operators.

(v) Owners and operators must retrain each person required to use dermal protection at least annually or whenever the owner or operator has reason to believe that a previously trained person does not have the required understanding and skill to properly use dermal protection, or when changes in the workplace or in dermal protection to be used render the previous training obsolete.

(5) Engineering controls. Owners or operators manufacturing cyanoacrylate adhesives using PIP (3:1) as an intermediate processing aid must use the following engineering controls:

(i) Must take place in a closed loop system, and

(ii) General and local exhaust ventilation must be provided.

(6) Workplace protection records. (i) Owners or operators subject to requirements described in this section must retain records of:

(A) The name, workplace address, work shift, job classification, and work area of each person reasonably likely to directly handle PIP (3:1) or handle equipment or materials on which PIP (3:1) may be present, and the type of PPE selected to be worn by each of these persons;

(B) The basis for the regulated area as defined in § 751.403, including monitoring data and documentation of any controls or combination of controls that have reduced exposure to where airborne concentrations of PIP (3:1) can no longer reasonably be expected resulting in a smaller or no regulated area being established;

(C) The type of PPE selected by the owner or operator for use by each of these persons, the respiratory protection used by each potentially exposed person and PPE program implementation, including fit-testing and training;

(D) The basis for PPE selection (e.g., demonstration based on permeation testing or manufacturer specifications that each item of PPE selected provides an impervious barrier to prevent exposure during expected duration and conditions of exposure, including the likely combinations of chemical substances to which the PPE may be exposed in the work area);

(E) Appropriately sized PPE and training on proper application, wear, and removal of PPE, and proper care/disposal of PPE; and

(F) For owners and operators using PIP (3:1) as an intermediate processing aid in the manufacturing of cyanoacrylate adhesives, compliance with paragraph (f)(5) of this section.

(ii) These records must be maintained for a period of five years from the date the record is generated.

(iii) These records must be made available to EPA upon request.

(iv) The owner or operator must provide potentially exposed persons and their designated representative an opportunity to observe records related to the basis of the PPE or another control measure selection, including potential monitoring results that is representative of the potentially exposed person's exposure.

(7) Exclusions. The following are not subject to the workplace protection requirements of paragraph (f) of this section:

(i) Import of PIP (3:1) and PIP (3:1)-containing products and articles.

(ii) Processing of PIP (3:1)-containing adhesives and sealants, specialized engine filters for locomotive and marine applications, and the products or articles described in paragraphs (b)(1)(vi) and (vii) of this section.

(iii) Processing of PIP (3:1)-containing new and replacement parts to which PIP (3:1) has been added for motor and aerospace vehicles and for manufacturing, HVAC, refrigeration and water heating equipment, electric and electronic equipment, and power generating equipment and the motor and aerospace vehicles, manufacturing, HVAC, refrigeration and water heating equipment, electric and electronic equipment, and power generating equipment that contain new and replacement parts to which PIP (3:1) has been added.

(iv) Processing of PIP (3:1) and PIP (3:1)-containing products for use as an intermediate to produce cyanoacrylate adhesives when PIP (3:1) and PIP (3:1)-containing products are contained in a closed system as described in paragraph (f)(6) of this section are not subject to the provisions of paragraphs (f)(3) and (4) of this section.
