YES, this is TRUE.

The two main types of hazards associated with confined spaces are physical hazards and atmospheric hazards. Physical hazards include risks such as entrapment, falls, or equipment-related dangers, while atmospheric hazards involve the presence of harmful gases, lack of oxygen, or toxic substances that can lead to suffocation or poisoning. Both types of hazards can pose significant risks to individuals working in or entering confined spaces. Proper safety protocols and monitoring are essential to mitigate these risks.

The primary purpose of the Confined Space Program Team (CSPT) is to ensure the safety of workers who enter confined spaces by developing and implementing procedures, training, and monitoring. The team is responsible for identifying, evaluating, and controlling hazards associated with confined spaces to prevent accidents and injuries.
Employers are typically responsible for identifying, evaluating, and classifying all confined spaces under their area of control. They must ensure that proper safety measures and protocols are in place for working in confined spaces to protect their workers from hazards. This responsibility is often outlined in regulations such as OSHA standards in the United States.
Atmospheric testing is conducted for monitoring air quality to ensure human health and environmental protection. It is also done to gather data and insights on atmospheric conditions for weather forecasting and climate research purposes.
Confined spaces training typically covers the identification of confined spaces, the hazards associated with them, and the necessary safety procedures to mitigate risks. Participants learn about proper ventilation, atmospheric testing, and the use of personal protective equipment (PPE). The training also emphasizes emergency response protocols and the importance of having a rescue plan in place. Overall, the goal is to ensure that workers can safely enter, work in, and exit confined spaces.
Confined spaces pose several hazards, including oxygen deficiency, where the level of breathable air is low; toxic atmospheres, which can contain harmful gases or vapors; and flammable atmospheres, which may lead to explosions or fires. Physical hazards, such as engulfment from materials or machinery, can also pose significant risks. Additionally, the confined nature of these spaces can limit rescue efforts in emergencies, increasing the overall danger to workers.
Confined spaces training prepares employees who work in confined spaces to follow OSHA requirements. This training provides workers with such information as how to identify hazards and how to follow proper rescue procedures.
