- Executive Summary - Centers for Disease Control and Prevention
Calibrate and maintain gas detection equipment properly by performing bump testing at the beginning of each shift following manufacturer’s guidance Use of gas detection equipment under a wide variety of conditions including when at the lower explosive limit (LEL) and upper explosive limit (UEL) of a gas or vapor

They may also be most appropriate for application in areas near seals and in tailgate entries Improving methane detection and ventilation The greatest effect on methane monitor response time is a dust cap over the sensor of the monitor All sensors have dust caps to protect the sensor head from the harsh influences of the mining environment
- Guidelines for the Control and Monitoring of Methane Gas on Continuous . . .
“A desirable development would be the equipping of these [continuous] mining machines with a dependable automatic instrument for detection and warning of the presence of methane in concentrations approaching the lower explosive limit”

Carbon monoxide (CO) is an odorless, colorless gas that can cause sudden illness and death if inhaled Find quick facts about CO poisoning and what can be done to prevent it
- Handbook for Methane Control in Mining
Subsequent chapters describe methane control methods for different kinds of mines and mining equipment, primarily for U S coal mines These coal mine chapters include continuous miners and longwalls, including bleeders Coal seam degasification is covered extensively Other coal mine chapters deal with methane emission forecasting and predicting the excess gas from troublesome geologic

EVALUATION OF METHOD: The method was reevaluated and revised Improvements were made to enhance the recovery of methanol from silica gel, to improve baseline resolution, and to improve the precision of the method Desorption efficiency (DE) was determined for three levels using the improved analytical parameters stated on page 2000-1 The average DE for methanol wasdetermined at 20 μg (0 942
