Atmospheric testing plays an important role in keeping workers safe in the construction industry. Like the OSHA general industry standard, the construction safety standard requires testing the atmosphere to verify that it is safe before anyone enters the confined space.
Every atmospheric testing program associated with confined space entry is filled with choices that ultimately affect the safety of workers as they perform their daily duties. Typically, the program is far from the core competency and productive focus of the company. Too often, this causes the program to concentrate on doing only what is necessary to comply with the rules.
