They
consist of the application of techniques of samplings
for the accomplishment of physical and chemical agents'
present quantitative evaluations in the work atmosphere
through measurements of the concentrations of the pollutants
(substances and chemical compositions) or of the physical
agents' intensities (noise, vibrations, heat, etc) and
subsequent comparison with the respective limits of tolerance
of NR 15 (L. T) or ACGIH (American Conference Industrial
Government of Hygienists).
The result of an environmental evaluation
will be documented in a technical report (LTCAT), identifying,
among other specifications, the environmental conditions
of work, the noxious agents' registration and conclusion
that the exhibition the these are or not harmful to the
health or the physical integrity.
LTCAT is an opinion circunstanciado and conclusive of the
environmental conditions the one that the employee was exposed,
owing, however, to reflect the reality in the moment of
the attainment of the it inspects. The decision has the
function of releasing her it inspects of WELFARE DEPARTMENT,
however, if incomplete, lacunoso or doubtful ensejará
inspects her/it in loco for the fiscalization.
LTCAT should be signed by engineer of safety of the work,
with the respective number of the Annotation of Technical
Responsibility (ART) close to the Regional Council of Engineering
and Architecture (CREA) or for doctor of the work, indicating
the professional registrations for both.
The (LTCAT) that should contain among other data: data of
the company; work section, description of the places and
of the services accomplished in each section, with pormenorização
of the work atmosphere and of the functions, I pass the
step, developed by the held; environmental conditions of
the work place; the noxious agents' registration, concentration,
intensity, time of exhibition and used methodologies, according
to the case; in if taking care of chemical agents, it should
be informed the name of the substance it activates, not
being accepted citations of trade names, could be enclosed
the respective toxicological record; duration of the work
that exposed the worker to the noxious agents.
