OSHA & Safety Regulations in Construction

OSHA Definitions and Competency in Safety

  • OSHA Definitions

    • Competent Person

    • Defined by OSHA as someone who:

      • Can identify hazards.

      • Understands the implications of those hazards.

      • Knows how to control hazards.

      • Must possess the authority to implement changes on site.

    • Qualified Person

    • Understands hazards and controls but lacks the authority to make changes.

    • Importance of distinguishing between competent and qualified persons, especially on construction sites.

Focus Four Hazards in Construction

  • Focus Four Hazards (most cited hazards in the construction industry every year)

    • Falls

    • Struck By (objects)

    • Caught Between

    • Electrocution

    • Clarifications:

      • Electrocution refers to death; shock refers to injury.

Incidents Involving Multiple Employers

  • OSHA can cite multiple entities for violations based on their roles in incidents that occur on site.

  • Example of a construction scenario:

    • General Contractor (GC) overseeing multiple subcontractors.

    • Cited if recognized hazards are not controlled effectively.

    • In an example, a leading to structural failure due to poor practices by block layers resulted in citations for both the GC and the subcontractors involved.

Responsibilities of General Contractors

  • GCs must vet subcontractors by reviewing:

    • Safety procedures/documentation

    • Incident history

  • If abnormalities are seen in subcontractor safety practices, GCs must decide to intervene carefully due to liability concerns.

  • Larger companies often have stricter requirements for subcontractors to follow their safety policies before entering sites.

Working Alone on Construction Sites

  • The risks of working alone highlighted by a case study where a worker was pinned by a mower for an hour and could not reach help, supporting the emphasis on the importance of having a buddy system.

    • The absence of safety features like a seatbelt on rental equipment led to severe consequences.

Personal Protective Equipment (PPE)

  • Common PPE in construction includes:

    • Reflective Vests

    • Steel-Toed Boots

    • Hard Hats

    • Eye Protection

    • Metatarsal Boots: Provide protection to the entire foot and ankle, not just the toes.

    • Standard practice is to wear multiple PPE items depending on the specific tasks being performed.

Falls Prevention in Construction

  • Fall protection regulations for heights above 6 feet:

    • Must be in place (e.g., guardrails, fall arrest systems).

    • Guardrails include:

    • Top rail

    • Middle rail

    • Toe guard

  • Fall Arrest Systems (FAS) include harnesses and lanyards, emphasizing the importance of proper selection and usage of equipment to prevent injuries.

Use of Equipment on Construction Sites

  • Scaffolding must meet specific standards, safety mechanisms, and regulations set by OSHA (i.e., 29 CFR 1926, Subpart L).

  • Equipment should be correctly rated, maintained, and checked for safety, such as being double insulated or grounded to prevent incidents.

Hazardous Conditions in Construction

  • Electrocution: All tools must be of appropriate standards (double insulated, grounded). Implement GFCIs (Ground Fault Circuit Interrupters) which cut power in case of faults.

  • Confined Spaces: Defined by:

    • Limited means of entry/exit.

    • Not designed for continuous human occupancy.

    • Potential for hazardous materials.

Incident and Injury Statistics

  • DART Rate (Days Away, Restricted, or Transferred):

    • Measures incidents resulting in time away from the workplace.

    • Important for evaluating safety performance.

  • TRIR (Total Recordable Incident Rate):

    • Measures total recordable incidents in a given time frame.

    • Comparison of rates critical for assessing subcontractor safety.

General Safety Practices and Discussions

  • Understanding cognitive ergonomics in safety equipment and procedures.

  • Administrative Controls vs. Engineering Controls highlighted in the context of safety practices and signage.

  • Importance of workforce training on emergency response and safety awareness in high-risk environments.

Key Takeaways

  • Comprehension and application of OSHA standards are critical for operational safety in the construction industry.

  • Accountability and authority in roles can significantly impact site safety and risk management practices.

  • Engagement in proactive safety measures can mitigate risks and enhance overall safety culture on construction sites.

  • Questions to ponder:

    • How does one ensure compliance across various contractors?

    • What are the impacts of insufficient training and resources on site safety?

    • How do psychological factors influence worker safety and decision-making?
