|
| At which noise level do you need dual hearing protection? A. 90 dB; B. 95 dB; C. 100 dB; D. 105 dB |
D. 105 dB |
|
| You are in an environment where the noise level is 100 dBA. Which ear plugs would protect you to the MSHA PEL? A. PVC foam (NRR 33); B. Composite foam (NRR 23); C. Polyurethane foam (NRR 25); D. Polyurethane foam (NRR 22) |
A. PVC foam (NRR 33) |
Subtract 7 dB from the NRR if noise is measured on the A-weighted scale. Divide by 2. Subtract from noise level. 4. Compare to MSHA PEL of 90 dBA TWA8 |
| A self-contained self rescuer (SCSR) should be donned at the first sign of this condition. |
Fire or smoke |
|
| What is the duration a W65 self-rescuer should last with 1% CO atmosphere? |
60 minutes |
|
| A W65 uses a chemical called hopcalite to change CO into CO2 but will not protect you in this type of atmosphere. |
Oxygen-deficient |
|
| When using either an oxygen-generating unit or W65, it is important to respond in this way, to ensure it lasts longer. |
