Exposures to crystalline silica are
addressed in specific standards for the general industry, shipyard employment,
and the construction industry. This page highlights OSHA standards, the
Regulatory Agenda (a list of actions being taken with regard to OSHA standards),
preambles to final rules (background to final rules), directives (instructions
for compliance officers), and standard interpretations (official letters of
interpretation of the standards) related to crystalline silica.
Section
5(a)(1) of the OSH Act, often referred to as the General Duty Clause,
requires employers to "furnish to each of his employees employment and a
place of employment which are free from recognized hazards that are causing or
are likely to cause death or serious physical harm to his employees". Section
5(a)(2) requires employers to "comply with occupational safety and
health standards promulgated under this Act".
Note:
Twenty-four states, Puerto Rico and the Virgin Islands have OSHA-approved
State Plans and have adopted their own standards and enforcement
policies. For the most part, these States adopt standards that are
identical to Federal OSHA. However, some States have adopted different
standards applicable to this topic or may have different enforcement
policies. |
