The Occupational Safety and Health Act grants OSHA the authority to issue workplace health and safety regulations. These regulations include limits on hazardous chemical exposure, employee access to hazard information, requirements for the use of personal protective equipment, and requirements to prevent falls and hazards from operating dangerous equipment. The OSH Act's current Construction, General Industry, Maritime, and Agriculture standards are designed to protect workers from a wide range of serious hazards. Examples of OSHA standards include requirements for employers to provide fall protection such as a safety harness/line or guardrails; prevent trenching
cave-ins; prevent exposure to some infectious diseases; ensure the safety of workers who enter confined spaces; prevent exposure to harmful chemicals; put guards on dangerous machines; provide respirators or other safety equipment, and provide training for certain dangerous jobs in a language and vocabulary workers can understand. OSHA sets enforceable
permissible exposure limits (PELs) to protect workers against the health effects of exposure to hazardous substances, including limits on the airborne concentrations of hazardous chemicals in the air. Most of OSHA's PELs were issued shortly after the adoption of the OSH Act in 1970. Attempts to issue more stringent PELs have been blocked by litigation from the industry; thus, the vast majority of PELs have not been updated since 1971. The agency has issued non-binding, alternate occupational exposure limits that may better protect workers. Employers must also comply with the General Duty Clause of the OSH Act. This clause requires employers to keep their workplaces free of serious recognized hazards and is generally cited when no specific OSHA standard applies to the hazard. In its first year of operation, OSHA was permitted to adopt regulations based on guidelines set by certain standards organizations, such as the American Conference of Governmental Industrial Hygienists, without going through all of the requirements of a typical rule-making. OSHA is granted the authority to promulgate standards that prescribe the methods employers are legally required to follow to protect their workers from hazards. Before OSHA can issue a standard, it must go through a very extensive and lengthy process that includes substantial public engagement, notice, and comment. The agency must show that a significant risk to workers exists and that there are feasible measures employers can take to protect their workers. In 2000, OSHA issued an ergonomics standard. In March 2001,
Congress voted to repeal the standard through the
Congressional Review Act. The repeal, one of the first major pieces of legislation signed by President
George W. Bush, is the first instance that Congress has successfully used the Congressional Review Act to block regulation. Since 2001, OSHA has issued the following standards: • 2002: Exit Routes, Emergency Action Plans, and Fire Prevention Plans • 2004: Commercial Diving Operations • 2004: Fire Protection in Shipyards • 2006: Occupational Exposure to Hexavalent Chromium • 2006: Assigned Protection Factors for Respiratory Protection Equipment • 2007:
Electrical Installation Standard • 2007: Personal Protective Equipment Payment (Clarification) • 2008: Vertical Tandem Lifts • 2010: Cranes and Derricks in Construction • 2010: General Working Conditions in Shipyards • 2012:
GHS Update to the Hazard Communication Standard • 2014: New Recordkeeping and Reporting Requirements for Employers • 2014: Revision to Electric Power Generation, Transmission, and Distribution; Electrical Protective Equipment • 2016: Occupational Exposure to Respirable Crystalline Silica • 2016: Update General Industry Walking-Working Surfaces and Fall Protection Standards ==Enforcement==
