## Diesel Particulate Matter Sampling

**MSHA Outreach Program**

## Types of Sampling

**Compliance Sampling**
**MSHA**
**Sampling/analytical methods spelled out in rule.**
**Environmental Monitoring**
**Mine Operator**
**No method specified, but must indicate whether limit exceeded.**

## Compliance Sampling

**Do not need to worry about interferences with EC surrogate.**
**Personal Sampling**
**Sample Time - Full Shift**
**Calculate with 480 minutes**

## DPM Sampling Train

**SKC Submicron Impactor**
**(Double Quartz-Fiber, Filter)**
**Cyclone**
**Breast Plate**
**Pump**

## DPM Sampler

## Calibration

**Pre calibration**
** **
**Post Calibration**
**1.7 Lpm**

## Personal Sampling

## Environmental Monitoring

**As often as necessary to determine:**
**Whether any miners overexposed,**
**Exposure of persons designated by MSHA.**
**Miners/miners’ rep must be given opportunity to observe monitoring.**
**If overexposure found, must correct.**
**Monitoring results must be posted, copy provided to miners’ rep.**
**Environmental monitoring records.**

## Sample Analysis

**Submit sample to lab - Make sure lab’s procedures followed (handling of sample cassettes, shipping, etc)**
**Complete lab paperwork and provide field notes, sampling documentation**

## Sample Analysis

**Total Carbon (DPM)**
**NIOSH 5040 - OC and EC**
**Sample - Top Filter**
** **
**Control - Double Filter**

## Carbon Analyzer

## Carbon Analysis - Thermogram

**Organic Carbon                 Elemental Carbon**

**OC  +  EC  =  TC**

**TC = OC + EC    or  TC = 1.3 x EC**

## Concentration Calculations

**TC = OC + EC**
**TC = 1.3 x  EC**
**OC* or EC* = **_**1000 x **__****__**g/cm**__**2**__** x Area**_
**                         ****1.7 x 480**
**Area = 9.12 sq. cm.**
***Corrected for control**

## Concentration Limit

**TC = 400 ********g/m****3**** **
**Error Factor**
**TC - 1.14**
**EC - 1.12**
**Compliance Ratio**
**  ****R =      **_**Concentration**_
**      ****Standard x Error Factor**

## Citable Violation

**Citable violation only if:**
**  ****EC + OC exceeds 400 x 1.14 = 456 ********g/m****3**** **
_**AND**_
**  ****EC x 1.3 exceeds 400 x 1.12 = 448 ********g/m****3**
**   ****Remember: MSHA will conduct compliance assistance sampling (no citations) until ****	****	****July 19, 2003**

## Sampling Results

**Make sure sample result relates to**
**Full shift exposure**
**Shift-weighted to 480 minutes**
**Airborne concentration of TC**
**Lab may report ********g on punch, ********g on filter, TWA instead of SWA, etc.**
**You may need to convert lab results to proper form (SWA ********g/m****3****)**
