Final answer:
Before work begins at a site, a competent person must identify all confined spaces and, through atmospheric testing, designate permit-required confined spaces. This form of testing is essential to detect any hazardous conditions within a confined space related to air quality and is a necessary measure to ensure the safety of those entering the space.
Step-by-step explanation:
Before work begins at a site, each employer must ensure that a competent person identifies all confined spaces. Also, through atmospheric testing, identifies each space that is a permit space. Recognizing a confined space is critical for workplace health and safety. Confined spaces can present numerous hazards, making them potentially dangerous. Environmental conditions within a confined space, such as a lack of oxygen, toxic gases, or flammable substances, need to be assessed through atmospheric testing before entry is permitted.
Atmospheric testing is crucial in providing information about the atmospherical conditions in the confined space and determining if the space is safe for workers or if respirators, ventilators, or other protective measures are needed. This test helps to protect against accidents and emergencies related to unsafe air quality which could lead to serious injuries or fatalities. When it comes to confined spaces, a visual inspection alone is not enough — the invisible threats that can lurk in the atmosphere are what make these areas uniquely hazardous.
Aside from confined space and atmospheric testing protocols, employers should also create and maintain written communication regarding the permit-required confined spaces. This includes documentation of the space's hazards, the means of controlling them, and the permit itself. A clear and detailed record-keeping system is vital for ensuring compliance with OSHA standards and for keeping all personnel informed and safe.
