32 C.F.R. § 627.30 Situations specified in §627.18(e).
Title 32 - National Defense
The clothing requirements for this section are for the emergency procedures specified in §627.18(e). Because situations can occur and there is no feasible or available means to mitigate the potential hazard adequately by engineering controls, the clothing requirements exceed those required for a properly conducted laboratory operation at an equivalent biosafety level. The protective equipment required will be selected based upon an assessment of the potential hazards that could be encountered. The following clothing requirements are given as a guide. The selection of PPE will be based upon the highest possible level of contamination that could exist in the room. This will be based upon what is known about the operations that were conducted in the room during and prior to the current incident. In each situation, the aerosols will be allowed to dissipate or settle before entry (approximately 30 minutes). The following clothing requirements apply to these situations: (a) BL–1. (1) Gloves. (2) Outer complete covering such as a pair of coveralls. (3) Shoe covers, provided shoes, or safety shoes or boots. (4) Eye protection (maintenance only). (b) BL–1 LS. The same as described in section 627.30(a) with the following additions: (1) An impervious apron. (2) Impervious boots. (c) BL–2 and toxins. (1) Gloves. (2) Full outer covering such as a coverall. (3) Shoe covers, provided shoes, or safety shoes or boots (maintenance). (4) An approved half-face or full-face respirator with HEPA filters (worn). (5) Eye protection. (6) An impervious apron (not required for entry only). (d) BL–2 LS. The same as §627.30(c) with the addition of impervious boots. (e) BL–3 and BL–3 LS. (1) A complete change of clothing. (2) Gloves. (3) An approved full-face HEPA or HEPA plus charcoal filtered respirator. (4) An impervious apron (not required for entry only). (5) Impervious boots. (6) Head cover. (f) BL–4. (1) A full change of inner clothing. (2) An inner pair of gloves. (3) A one-piece positive pressure suit as described in §627.31(g), or a one-piece Xsuit with an approved positive pressure self-contained breathing apparatus (SCBA) and a supplied-air respirator (SAR) or both (see §627.31(f)).
