Testing for hazardous atmospheres in confined spaces is critical primarily to ensure worker safety. Confined spaces can contain various hazards, including toxic gases, low oxygen levels, and flammable substances, which can pose serious risks to workers' health and lives. Conducting thorough testing helps identify these dangers before workers enter the space, allowing for the implementation of necessary safety measures, such as ventilation or use of personal protective equipment, to mitigate risks.

While avoiding project delays, complying with regulations, and decreasing construction costs are valid concerns, the overarching priority in these situations must always be the safety and well-being of the workers. Protecting them from potential inhalation of harmful substances, suffocation, or explosions directly ties into the fundamental ethos of occupational health and safety practices. Therefore, ensuring worker safety is the primary reason for testing hazardous atmospheres in confined spaces.
