Emotional stress


Job stress can pose a threat to the safety and health of workers. One-fourth of employees view their jobs as the number one stressor in their lives and three-fourths of employees believe the worker has more on-the-job-stress than a generation ago. Job stress results from the interaction of the worker (including worker characteristics) and the conditions of work. Stress may be part of a miner's response to the everyday workload in the dangerous mining environment or to an emergency situation or mine disaster. Stress awareness and the development of interventions for miners and the industry contribute to worker safety and health. From a psychological perspective, preparation is the most important activity in which to engage to mitigate the effects of a disaster.

Emotional Stress Spotlights

Man Mountain´s Refuge: Refuge Chamber Training Instructor´s Guide and Trainee´s Problem Book (PDF, 646 KB, 2011)
This instructor´s guide is designed for use by instructors who train mine employees on how and when to use a mine refuge chamber, and aids the instructor in reinforcing the critical decisions that have to be made during a mining emergency.

Underground Mine Refuge Chamber Expectations Training: Program Development and Evaluation (PDF, 1189 KB, 2011)
Refuge chambers are new devices for underground coal mines that provide approximately 96 h of breathable air, water, food, and supplies in the event of an emergency where miners are unable to escape. Researchers at the National Institute for Occupational Safety and Health (NIOSH) developed a training program to prepare miners for what to expect psychologically and physiologically inside of a refuge chamber. The field tests of this training revealed that it was received very positively by miners and helped impart realistic views about the physical discomforts and psychological stresses of being inside a refuge chamber.

Overtime and Extended Work Shifts: Recent Findings on Illnesses, Injuries and Health Behaviors (HTM, 2004-04)
This document presents an integrative review of the methods and findings from 52 studies that were published between 1995 and 2002 and examined the relationship between long work hours and selected health outcomes. The review indicates that the influence of long working hours on health and safety involves a complex interaction of a number of factors. The authors recommend issues and priorities to consider in future research.

Toward a Typology of Dynamic and Hazardous Work Environments (PDF, 265 KB, 2001-12)
The most hazardous work environments share one feature in common: constant change. Many different, but constantly changing hazards are found in agriculture, construction, mining, and transport. The authors propose a preliminary typology of dynamic and hazardous work environments, along with a schema to systematically observe the dynamic characteristics of these hazards.
