At hazardous waste sites, IDLH concentrations should be assumed to represent: B) Levels requiring the use of respirators that provide maximum protection .
Explanation :
IDLH stands for 'Immediately Dangerous to Life or Health'. It represents exposure levels that pose an immediate threat to life, cause irreversible or delayed adverse health effects, or interfere with an individual's ability to escape. Therefore, maximum protective gear, such as self-contained breathing apparatus or supplied-air respirators, should be used.
When must all suspected conditions that are immediately dangerous to life or health (IDLH) be identified? C) During the preliminary survey .
Explanation :
The preliminary survey is a crucial step in assessing a hazardous site. Identifying all potentially dangerous conditions at this stage helps ensure proper safety measures and plans are put in place before more detailed surveys or work are conducted.
Which of the following types of air monitoring equipment is easily carried by one person and does not require external power? D) Portable .
Explanation :
Portable air monitoring equipment is designed to be lightweight and easy to carry. It operates on internal power sources, like batteries, making it convenient for individual use to monitor air quality and ensure safety on-site.
These questions relate to important safety standards and procedures necessary to ensure the health and safety of workers handling hazardous materials. Understanding these principles is essential for maintaining safe working conditions.
