English to Romanian Tech/Engineering Safety

Confined spaces, like columns, storage tanks and silos, are among
the most hazardous work environments. Risk assessments and
occupational safety procedures for working in confined spaces must
therefore be followed meticulously and without error to avoid danger
to life.
A vital part of such procedures is to thoroughly check that the
confined space atmosphere is safe enough for workers to enter.
The process, known as clearance measurement, is to detect and
monitor any potential toxic gases or substances within the confined
space, and monitor oxygen levels, to make sure all values stay
within safe parameters. Without clearance measurement, confined
space entry and working in these environments pose even greater
danger to life through combustion or contamination by this poten-
tially occurring matter
