Confined space hazards are addressed in specific
standards for the general industry and shipyard employment. This page
highlights OSHA standards, directives (instructions for compliance
officers), standard interpretations (official letters of interpretation of
the standards), and national consensus standards related to confined spaces.
OSHA
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. |
