What Do You Know About Confined Spaces?

The statement emphasizes the importance of everyone understanding the precautions and procedures related to confined spaces in order to ensure everyone's safety. It implies that each individual has a responsibility to be knowledgeable and cautious in such environments. Therefore, the correct answer is "True."

If hazards are introduced into a non-permit space, it can become a permit space. This means that the space now poses potential dangers such as hazardous atmospheres, engulfment hazards, or other conditions that could be harmful to workers. As a result, specific safety protocols and permits must be implemented before anyone can enter the space to ensure their protection. Therefore, the statement "A non-permit space may become a permit space if hazards are introduced" is true.

The statement is false because signage for permit confined space should not be considered proprietary and confidential. It is important for the signage to be visible and easily understood by anyone who may enter the confined space, including employees, contractors, and emergency responders. Making the signage proprietary and confidential would hinder the communication and understanding of the potential hazards and safety precautions associated with the confined space.

IDLH is an acronym used to describe the condition where a substance poses an immediate threat to life or health. It is used to identify hazardous situations where exposure to a certain substance or environment can cause severe harm or death. This term is commonly used in occupational safety and health to determine the level at which workers must be protected from exposure to hazardous materials.

Employees need to have access to Material Safety Data Sheets (MSDS) at all times. MSDS provide important information about hazardous substances in the workplace, including their properties, potential hazards, and safety precautions. Having access to MSDS ensures that employees can make informed decisions about handling and using these substances safely.

The Attendant is responsible for maintaining communication with workers, signing in and out employees who enter and exit the space, and summoning the emergency response team if necessary. They can work on several things and periodically monitor the workers, but they may only be distracted by relevant operations that have been determined to be high risk.

This statement is true because before an employee enters a permit confined space, it is necessary to test the internal atmosphere for various factors such as oxygen content, potential toxic air contaminants, flammable gases, and vapors. This is done to ensure the safety of the employee and to identify any potential hazards that may be present in the confined space.

The correct answer includes tanks, storage bins, a properly shored trench, and silos. Confined spaces are areas that have limited entry and exit points and are not designed for continuous occupancy. Tanks, storage bins, silos, and a properly shored trench can all be considered confined spaces as they have limited access and may pose risks such as lack of ventilation, potential for engulfment, or hazardous atmospheres. The job connex, however, is not typically considered a confined space as it is a portable storage container and does not have the same inherent risks as the other options.

A rescue plan needs to be known by all employees to ensure that everyone is aware of the procedures and protocols in case of an emergency. It must be developed prior to entering a confined space and should consult local emergency response services to ensure that the plan is comprehensive and aligned with local regulations and resources.

When confined space entrance covers are removed, it is important to guard the opening to prevent accidents or unauthorized access. Railing and/or signage can be used to clearly indicate the danger and restrict entry. A temporary cover can be placed over the opening to prevent falls or objects from falling into the space. A temporary barrier can also be used to physically block access to the opening. OSHA regulated board stretchers and proper testing activities are not directly related to guarding the opening and are therefore not applicable in this situation.
