Final Guidelines for the Protection and Training of Workers Engaged In Maintenance and Remediation Work Associated with Mold 16 2.4 Course design Training courses should be developed to be consistent with the recognized principles of instructional design such as the ADDIE method (Analysis, Design, Development, Implementation, and Evaluation), the DOE Systematic Approach to Training manual (DOE- HDBK-1078-94), and ANSI Z-490. Useful additional references that specifically consider the NIEHS/WETP training target audience can be found in the WETP workshop report "Guidelines for Training of Workplace Safety and Health Programs: Guidance Document", November 1998 and on the WETP web site specific to the several bi-annual trainers exchange workshops. The method used needs be fully documented by the developer. 2.4.1 Content 2.4.1.1 Respirators and personal protective equipment The following consensus points were reached about respirators and PPE, which should be reflected in training design. Gloves Use of gloves is typically dependent on whether wet work or dry work is performed. Wet work requires that the glove choice be based on the liquid. There was a discussion noting that latex gloves cause allergic reactions in some wearers and their use should be discouraged. During dry work, the minority opinion was that reusable rough work gloves are acceptable. Eye protection The consensus was that workers should be given the opportunity to choose either safety glasses or vented goggles. Full-body coveralls Full-body coveralls are generally not needed for maintenance work, except in some unusual circumstances involving heavy exposures to mold. For remediation, non-porous, full-body coveralls, boots, and head coverings are recommended. Respirators for remediation workers NIOSH-approved, half-face elastomeric respirators with particulate cartridges of at least N-95 should be used, unless the environment might include oil mist exposures, in which case a P designation would be needed. Where heavy exposures are anticipated, improving the efficiency from 95 to 100 may be warranted. Although molds produce Microbial Volatile Organic Compounds (MVOCs), the general conclusion was that these are in such low concentrations (particularly considering the dilution inside containment from air handling equipment) that there is no need for charcoal filtration on the respirators. PAPRs should be recommended based on comfort and effectiveness. All respirators must be NIOSH certified.
