Notes: | 1. Only properly trained employees should select PPE. Hazardous materials technicians and hazardous materials specialists can select PPE within the competencies specified in Table 4. |
2. Selection requirements in other PPE rules also apply, including: | |
a. Chapter 296-307 WAC, Part Y-5, Respirators. | |
b. Chapter 296-305 WAC, Safety standards for firefighting. |
Note: | Follow the manufacturer's recommended procedure for testing a TECP suit's ability to maintain positive air pressure and prevent inward gas leakage. Other established test protocols for these suits, for example NFPA 1991 and ASTM F1052-97, may also be used. |
Table 9 Selecting PPE for Specific Hazards | |
If: | Then use: |
• Inhalation hazards could be present. | • Positive-pressure (pressure-demand) self-contained breathing apparatus (SCBA) or • A decreased level of respiratory protection only when the incident commander determines, from air monitoring results, that employees will be adequately protected. |
Chemical exposure levels will create a substantial possibility of: • Immediate death. • Immediate serious illness or injury. • Reduced ability to escape. | Either positive-pressure (pressure-demand): • SCBA • Air-line respirators equipped with an escape air supply. |
Skin absorption of a hazardous substance may result in a substantial possibility of: • Immediate death. • Immediate serious illness or injury. • Reduced ability to escape. | Protection equivalent to Level A including a totally encapsulating chemical protective (TECP) suit. |
