GUIDELINES TO ENSEMBLES FOR SPECIFIC ACTIVITIES/TASKS <br /> WHERE CHEMICAL EXPOSURE IS POSSIBLE <br /> IMPORTANT: READ FOOTNOTES AND ASSUMPTIONS/JUSTIFICATIONS PRIOR TO USING TABLE <br /> Notes: <br /> 1. This table is for use by trained environmental professionals only. To use this table: <br /> a. Scan the activity description to find activities (bolded) that most closely matches those you plan to engage in. <br /> b. Review Hazard/Conditions section to make sure the hazards of the planned activity match those listed. Note the <br /> Required Work Practices and be ready to follow them. <br /> c. For those activities most likely to be conducted as part the response, select Targeted Minimum PPE (Personal Protective <br /> Equipment). <br /> d. Necessary equipment needs to be available and used unless other information becomes available which necessitates an <br /> upgrade or allows a downgrade in the protection level. The work area must be continuously re-evaluated to ensure <br /> workers have the proper safety equipment. <br /> e. When working in hazardous environments, workers must always be aware of their surroundings. In addition to this Table, <br /> workers entering these environments need to use "common sense" prior to proceeding. <br /> 2. These ensembles focus on chemical protection and may not be adequate for all hazards. This Table can be used as a <br /> starting point but does not circumvent proper evaluation by an industrial hygienist in appropriate situations. See Table 2 for <br /> more specific chemical agents. <br /> 3. Suits, gloves, boots listed in the Minimum PPE column will not be appropriate for all activities, hazards and conditions. The <br /> listings should be used as a guide only. Confirm PPE compatibility with specific chemical contaminants. <br /> 4. A comprehensive Task Hazard Analysis must be performed prior to final selection of ensembles/PPE material types. <br /> 5. Hardhat (Class A or C), safety glasses/other eye protection are typically required but may not be specified here. In noisy <br /> environments (above 85dB) hearing protection is required. In areas where there is traffic, heavy machinery, or other hazards <br /> involving worker visibility problems a Class 2 High Visibility Vest must be worn. Activities requiring vests include natural <br /> disaster responses, demolitions, and excavations. <br /> 6. PPE makes and models referenced in these tables are only suggestions. Other comparable, adequate makes and models <br /> may be used. <br /> 1 <br />
