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?
Next Class Focus: A study on Chapter 17 is scheduled to further address safety standards and protocols.
