What is OSHA?

OSHA, the Occupational Safety and Health Administration, sets and enforces safety standards to protect workers across industries. It aims to reduce risks, injuries, and fatalities by ensuring employers follow guidelines on hazard communication, PPE, fall protection, and more.

The Occupational Safety and Health Administration (OSHA) is a federal agency within the U.S. Department of Labor responsible for ensuring safe and healthy working conditions for employees across various industries. Established by the Occupational Safety and Health Act of 1970, OSHA creates and enforces standards aimed at reducing workplace hazards and preventing injuries, illnesses, and fatalities.

OSHA sets guidelines that employers must follow, covering everything from equipment safety and exposure limits to reporting procedures and employee training. It also offers support through outreach programs, education, compliance assistance, and partnerships with industry stakeholders.

Why OSHA Matters

Workplace safety isn’t just a moral responsibility—it’s a legal requirement. OSHA plays a central role in ensuring that employers provide conditions free of recognized hazards, such as toxic chemicals, mechanical dangers, and unsanitary environments. Its mission: to reduce occupational risks and promote a culture of safety through both enforcement and education.

OSHA regulations apply to most private sector employers and employees in all 50 states, as well as some public sector workers through OSHA-approved state plans.

Core OSHA Functions

  • Creating Standards: OSHA develops detailed rules based on research, industry input, and consensus from advisory committees.
  • Enforcement: Through inspections and investigations, OSHA ensures compliance and may issue citations or fines for violations.
  • Training & Outreach: OSHA provides extensive training resources through initiatives like the Outreach Training Program (e.g., OSHA 10 and 30).
  • Recordkeeping & Reporting: Employers must document work-related injuries, illnesses, and fatalities, and report serious incidents within strict timeframes.

Examples of OSHA Requirements

Some common OSHA standards include:

  • Hazard Communication (HazCom): Ensures workers know about chemical hazards via Safety Data Sheets (SDS) and proper labeling.
  • Lockout/Tagout (LOTO): Procedures that prevent accidental equipment startups during maintenance.
  • Personal Protective Equipment (PPE): Employers must provide and ensure the use of gloves, helmets, eye protection, etc.
  • Fall Protection: Mandated for workers at heights of 6 feet or more in construction.
  • Noise Exposure Limits: Regulations on permissible noise levels in work environments.

How OSHA Impacts Employers

Compliance with OSHA rules is not optional. Employers must:

  • Maintain a workplace free from serious hazards (the General Duty Clause).
  • Display the official OSHA poster outlining rights and responsibilities.
  • Provide training in a language and vocabulary workers can understand.
  • Maintain injury and illness records (OSHA 300 logs).

Failure to meet OSHA regulations can result in penalties, litigation, or increased workers’ comp claims.

OSHA and Safety Management in Construction

Construction remains one of the most hazardous industries, with high rates of workplace injuries and fatalities. OSHA plays a critical role in shaping safety management systems (SMS) for construction companies, setting clear guidelines that protect workers from preventable risks like falls, electrocution, struck-by incidents, and caught-in/between accidents—the so-called “Fatal Four.”

Under OSHA’s construction standards (29 CFR Part 1926), employers must implement proactive safety practices that go beyond compliance. This includes:

  • Site-Specific Safety Plans (SSSPs): OSHA expects contractors to assess site hazards and prepare documented safety strategies before work begins.
  • Job Hazard Analyses (JHAs): A process to identify task-specific risks and define mitigation measures for each phase of work.
  • Toolbox Talks and Daily Briefings: OSHA encourages regular safety discussions to reinforce training and keep awareness high on dynamic job sites.
  • Fall Protection Programs: Required whenever employees are working at heights of 6 feet or more.
  • Scaffold, Trench, and Heavy Equipment Protocols: OSHA mandates specific training and controls for high-risk operations common in construction.

Construction employers must also assign a competent person—someone capable of identifying hazards and authorized to take corrective action—on every jobsite.

FAQs

What are the “OSHA Focus Four” hazards in construction?

OSHA identifies four leading causes of fatalities in construction, known as the Focus Four:

  1. Falls
  2. Struck-by objects
  3. Electrocutions
  4. Caught-in/between hazards

Does OSHA require a written safety plan for construction projects?

While OSHA doesn't mandate a single “universal” safety plan, it does require employers to identify, evaluate, and control hazards. In practice, this often means creating a Site-Specific Safety Plan (SSSP) that includes hazard assessments, safe work procedures, emergency contacts, and training logs. Written plans are especially important for compliance during inspections and audits.

Who qualifies as a "competent person" on a construction site?

Under OSHA standards, a competent person is someone who:

  • Is capable of identifying existing and predictable hazards, and
  • Has the authority to take prompt corrective measures.
